Description

 SYSTEM AND METHOD FOR SIMULTANEOUSLY RECORDING MEASURED DATA AND VIDEO AND / OR AUDIO DATA

The invention relates to a system for the simultaneous recording of measurement data and video and / or audio data, consisting of at least one data processing device, at least one measurement data recording device connected to the data processing device via at least one interface, and at least one device connected to the data processing device via at least one interface for recording video and / or audio data, the data processing device being set up to receive data recorded by the device for recording video and / or audio data via the interface.

Furthermore, the invention relates to a method for the simultaneous recording of measurement data and video and / or audio data, in which measurement data are recorded by a measurement data recording device, furthermore data are recorded by a device for recording video and / or audio data, and both Measurement data as well as the audio and / or video data are transmitted to a data processing device.

Doctors and therapists are increasingly confronted with a growing need for psychological and psychotherapeutic help. In clinical psychosomatics, psychiatry and psychotherapy, for example, this requires a) well-trained doctors and therapists, combined with proof of quality and quality assurance of medical and therapeutic action, and b) research, documentation and evaluation of therapeutic measures.

At the moment, however, proof of quality regarding medical or therapeutic activity is only provided in the rarest of cases, and documentation of therapeutic measures is only carried out in very few cases. In the rare cases where such documentation is carried out, a therapy session is usually recorded audiovisually on video tapes so that, for example, it can be viewed again later and the appropriate conclusions drawn. Subsequent editing may also be carried out using video editing systems. Additional recording and storage, for example of medical measurement data relating to the patient, is generally not carried out, since this would involve a great deal of time and technical effort. During such therapy sessions, it is often also of interest to observe the physical reactions of the person to be treated in a situation in the brain, for example a change in heart rate, a decrease in skin resistance, which indicates increased sweating of the person, etc.

A link of such measurement data with the audiovisually recorded data is of particular interest. However, there is currently no way to enable such a link.

US Pat. No. 6,241,668 describes an EDP system in which various imaging medical devices are connected to a central EDP / image storage via data lines, e.g. B. X-ray, CT, NMR. Computers are also connected to the system for entering patient data and for sending / retrieving images and data in this system. In addition, a digital photo or video camera or a scanner for taking pictures of the patient, for example an identification photo, can also be connected.

A device shown in WO 00/08585 is used in operations. This consists of a video camera, a monitor for the ongoing direct display of the operation and a switch, such as a foot switch, for storing individual images. Furthermore, the device includes a microphone for recording comments from an operator and a second switch for storing these comments. Finally, the device also includes a timer that provides the images and comments with the current time, and a computer with software to combine this data.

US 5,776,057 shows a general device for measuring EKG, EEG and any other biological signals. The measurement procedures are stored in the device, and the corresponding procedure is then selected for taking a measurement.

The US 5,205,800 shows a treadmill (fitness device) with a video screen, in which a video cassette is played during the running training, on which a running route is shown. Depending on the incline and pace on the running track, the incline and pace of the treadmill are set automatically.

Some of these systems show the use of video recording devices in medicine, sometimes also together with the recording or input of patient (measurement) data. However, none of these systems directly affects the topics and, accordingly, these documents do not offer any solutions to these problems.

Accordingly, it is an object of the invention to enable the above-mentioned linking of measurement data with audio and / or video data, which in particular makes it possible to have the recorded measurement data relating to the patient immediately available when the recording is played back later.

This object is achieved with a system mentioned at the outset, which is characterized in that, according to the invention, the data processing device is set up to compress the video and / or audio data and, together with the measurement data transmitted by the measurement data breathing apparatus, in at least one common one Saving data files on a storage device, the data processing device being further set up to break down the measurement data into measurement data packets, further breaking down the compressed video and / or audio data also into data packets, and the measurement data packets in the data file in the data stream of the video and / or or save audio data packets.

With such a system according to the invention, it is possible in a simple manner, for example, on the one hand to record a person audiovisually during a therapy session, furthermore in this situation to measure measurement data about this person, for example the heart rate, and to feed it to the data processing device, and this audio and / or visual Save data together with the measurement data so that they are available together and can also be viewed together in a simple manner when the recorded session is displayed.

However, the invention is not only limited to use in psychotherapeutic sessions, the system according to the invention can also be used in the field of physicotherapy and sports medicine, for example for documenting progress and therapy or training in comparison to the initial values.

Additional areas of application are also evident in everyday life: B. as theft monitoring device in closed rooms (highly sensitive motion sensors switch to recording when moving) or as a public-friendly connection at sporting events such. B. Formula I races.

For example, in Formula I races, the driver of a racing car can be provided with a simple pulse monitor or connected to an electrocardiograph, and the like Corresponding data are then transmitted together with the video / audio data of an on-board camera to a data processing device, processed accordingly and then displayed on television. The driver's pulse rate can then be displayed, for example, as a number on television. The measurement data recording device can, for example, communicate with the data processing device itself by radio, or it is connected to the on-board camera to which the measurement data is transmitted and from which it is then forwarded to the data processing device.

The measurement data, for example the pulse frequency, are transmitted to a data processing device together with the video / audio data of an on-board camera, processed and stored accordingly. The measurement data can appear on the one hand at the same time as the picture on television, and on the other hand can be used for any analysis due to the storage, for example for displaying the scene with the highest / lowest pulse frequency.

The storage in a common data file on a storage device enables the recorded situation to be viewed later, even several times. A hard disk, CD-ROM, DVD etc., for example, can be used as the storage device, which offer sufficient storage space to accommodate the recorded amounts of data. The temporally related video / audio data and the measurement data are stored in a common data file in order to have related information available at the same time. In this way, it is also easily possible, for example, to quickly find the video / audio sequence (s) belonging to a specific measured value. Furthermore, the entire recording is usually recorded in one data file, but it can also be that it is divided into several data files if this appears to be favorable. It is only important that, as already mentioned, video / audio data and measurement data that belong together in time are each stored in a common file.

It is particularly advantageous because it saves memory and resources if the data processing device is set up to write the measurement data as well as the video and / or audio data into the at least one common data file immediately after it has been received and after any compression on the data processing device, since in In this case, it is not necessary to temporarily store large amounts of data in a working memory (RAM, “random access memory”) of the data processing device.

The device for recording video and / or audio data usually transmits the video data in digital, compressed form, for example in digital video (DV) format, to the data processing device, which then decompresses the video data and then compressed again. For example, the device can be a video camera with which the video and audio data are recorded, the video data is compressed and then transmitted to the data processing device.

The audio data is usually transmitted from the video camera to the data processing device in an uncompressed form, where it is then compressed accordingly.

As a rule, the at least one interface is a wire interface, via which the device for video / audio data recording and the measurement data recording device are connected. Such interfaces are well known and are widely used.

In the sense of a free arrangement of the interconnected devices it is when the at least one interface is a radio interface. Of course, it is also possible for one or more devices to be connected to the data processing device via a radio interface, and other devices via a wire interface.

The interfaces are, for example, serial interfaces, for example an RS-232 interface and / or USB interfaces and / or interfaces based on the Firewire standard. The Firewire interface (also known as IEEE1394 from the "Institute of Electrical and Electronics Engineers") is particularly suitable for the invention, since particularly high data rates can be transmitted via these interfaces. A broadband radio transmission of the data can, for example, be carried out via the planned, future Wireless Firewire standard.

The use of an infrared interface is also possible, at least for the transmission of the measurement data to the data processing device.

In order to be able to use the system according to the invention as diverse as possible, as will be explained in more detail later, the at least one or at least one of the several measurement data recording devices is set up at least for the measurement of physical measurement variables.

For medical use or for recording therapeutic sessions, it is expedient if the at least one or one of the plurality of measurement data recording devices is set up at least for measuring vital parameters of a test person or an animal. In order to allow certain recording sections to be found quickly, it is expedient if the data processing device is set up to provide the at least one data file with one or more markings.

So that this marking process can take place in front of a patient as inconspicuously as possible, it is favorable if the data processing device can be connected to at least one remote control and the markings in the data file can be made using the remote control.

It is particularly expedient if the data processing device is set up to compress the video data using a method according to MPEG and to save them in compressed form. With this format, it is easily possible to link this data with the recorded measurement data.

Furthermore, it is favorable if the data processing device is set up to compress the audio data using a method according to MP2 or MP3 and to save them in compressed form, since in this way a high compression rate of the audio data can be achieved and the quality losses due to the compression are hardly noticeable are.

The initially mentioned object is further achieved with a method mentioned at the outset in that, according to the invention, the video and / or audio data is compressed by the data processing device and, together with the measurement data transmitted by the measurement data recording device, is stored together in at least one common data file on a storage device , the measurement data being broken down into measurement data packets, the compressed video and / or audio data also being broken down into data packets, and the measurement data packets being stored in the data file in the data stream of the video and / or audio data packets.

The advantageous embodiments of the method according to the invention have already been discussed in more detail in connection with the system according to the invention.

The invention is explained in more detail below with reference to the drawing. In this show

Fig. 1 is a schematic representation of a system according to the invention, and

Fig. 2 is a schematic representation of the sequence of a method according to the invention.

1 shows a system SYS according to the invention, consisting of a device for data processing, for example a known personal computer COM, to which via interface SCHI, SCH2 a device CAM for recording video data and a device MIC for recording audio data are connected. The video data recording device CAM is, for example, a known video camera, and the audio data recording device is a microphone MIC. Usually, however, contrary to the illustration shown in FIG. 1, the microphone will be integrated in the video camera.

1, a measurement data recording device MES is connected via a further interface SCH3. For example, the measurement data recording device MES shown is an electrocardiograph, i.e. a device for recording the electrocardiogram, in a greatly simplified representation. The recorded measurement data in the application shown is therefore the curve image recorded by the electrocardiograph (time profile) of the bioelectrical potentials or potential differences which arise in the heart during the spreading and regression of excitation. The derivation takes place with the aid of electrodes ELK from the body surface or directly from the heart of a person to be examined PER, and the measurement data thus supplied to the electrocardiograph MES are fed to the computer COM via the interface SCH3.

The interfaces SCHI - SCH3 are, for example, serial interfaces, infrared interfaces, etc. In particular for the transmission of the video data, it is advantageous if at least the interface SCHI is an interface for transmitting high data rates, for example a USB or An interface is based on the Firewire standard ("IEEE1394"). Radio interfaces are also suitable for high-speed data transmission, for example on the "Bluetooth" standard or on the future, planned WirelessFirewire standard.

For example, the Firewire interface is a so-called multiplex interface, so that communication between the individual devices CAM, MIC, MES is possible via only one interface on the computer COM and a corresponding interface for each of the devices.

At this point it should be noted that it is in principle also possible to connect the measurement data recording device MES to the camera CAM which is then set up accordingly and which then transmits the measurement data to the computer COM. This is particularly necessary if a direct connection of the measurement data recording device to the computer is not possible or is only possible with difficulty. Of course, it is also possible to connect several video cameras and / or video cameras and in particular several measurement data recording devices for recording medical parameters relating to the person PER to the computer. In addition to the electrocardiographs, important medical devices include blood pressure monitors, devices for measuring blood oxygen saturation, electroencephalographs (EEG), skin resistance meters, devices for measuring respiratory rate, etc.

With the corresponding devices CAM, MIC, the person to be recorded PER records video data vid and audio data aud and transmits them to the computer COM. As can be seen in FIG. 2, in which the method according to the invention is shown schematically, the video data vid are recorded and compressed, for example, by a video camera with an integrated microphone, and the compressed video data vid 'present in digital form is sent to the computer COM via the corresponding interface transfer. The audio data aud recorded with the microphone MIC of the video camera CAM are also recorded and transmitted to the computer COM.

In the case of a digital camera, the audio data aud are already digitized in the camera CAM, when using an analog camera, such as VHS cameras, however, the audio data are transmitted in analog form to the computer COM and only digitized in the computer COM. For this purpose, the audio data aud are fed, for example, to a so-called “video capture” card or a sound card, from which the digitization is carried out.

In the decompressed form, the video data vid and the audio data aud can be output via a corresponding output device of the computer COM, i.e. are usually output via a display such as a monitor and via loudspeakers.

Furthermore, according to the invention, measurement data mes recorded with a corresponding measurement data recording device, for example measurement data mes recorded with an EKG device MES, are forwarded to the computer. In a computing unit CPR of the computer COM, which as a rule consists of a working memory and one or more processors, these incoming data vid, aud, mes are processed accordingly and then in a storage device SPE, for example a hard disk of the computer, a CD-ROM , DVD etc. are stored.

The video data vid are usually recorded by the video camera CAM and brought into a digitally compressed form vid ', usually using a DV compression process ("digital video"). mated video data vid 'decompressed and in turn compressed, mostly by a method according to MPEG, which will be discussed in more detail below. In principle, any other compression method that offers a corresponding compression factor is also possible, but the use of MPEG offers certain advantages, which will also be discussed below.

The audio data aud are usually transmitted from the video camera or another, independent recording device MIC to the computer COM in an uncompressed form and brought into a compressed form aud * in its computing unit CPR, for example by a method such as MP2 or MP3. In principle, however, it is also possible to leave the audio data uncompressed.

The recorded measurement data are fed to the computer COM or its computing unit CPR via a further channel, but remain uncompressed.

The compressed video data vid *, the compressed audio data aud * and the measurement data mes are stored in data packets vid * (l), vid * (2), vid * (3), vid * (4), ..., in the computing unit CPR. aud * (l), aud * (2), aud * (3), aud * (4), ..., mes (l), mes (2), mes (3), mes (4), etc. disassembled and built into a system stream as explained below and thus stored in a common file or a common data file dat in the storage device SPE. It should be noted here that FIG. 2 shows the actual situation in a considerably simplified manner, since normally in such a system stream, significantly more video data packets vid * (l), vid * (2) etc. than packets with audio data aud * ( l), ... or measurement data mes (l), etc. are included.

In order to allow a quick location of certain recording sections, which, for example, a therapist considers important, it is expedient if the data processing device is set up to provide the at least one data file with one or more markings. It is possible, for example, that a measurement data channel is used specifically for the markings; the bytes of this channel are e.g. normally 00, markings are identified by another value, e.g. 01. However, there is also the alternative of accommodating the headers of the compressed MPEG image data - each image has such a header - so-called "user data", which could then contain such markings but also short commentary texts.

So that this marking process can take place in front of a patient as inconspicuously as possible, it is favorable if the data processing device COM has at least one Remote control FER is connectable and the markings in the data file can be attached using the remote control FER.

The MPEG compression method ("Motion Pictures Expert Group") for compressing video data will be briefly discussed below.

MPEG: First, the compression of single frames of the video according to the MPEG1 standard of the Moving Pictures Expert Group will be dealt with here. In a first step, the color resolution of an image to be compressed is reduced, whereby the amount of data can be reduced, for example, by 50%. For further details on MPEG see also: Khalid Sayood, Introduction to Data Compression (2nd Edition, 2000, Morgan Kaufmann Publishers), especially chap. 16 pp. 529-560 and pp. 531-534; "Information Technology - Coding of Moving Pictures and Associated Audio for Digital Storage Media Up to about 1.5 Mbit / s" (ISO / IEC IS 11172 on the MPEG-1 standards); J.L. Mitchell, W.B. Pennebaker, C.E. Fogg, D. LeGall: MPEG Video Compression Standard, New York: Chapman and Hall, 1997.

First there are three drawing files, namely one for each of the three primary colors red, green and blue. Before this color reduction can be carried out, these three partial images must also be converted into three partial images, one with the brightness information, which in itself is a black and white image, and two partial images with the color information (red component and blue component). This conversion from red-green-blue (RGB) to brightness-blue component-red component is called the RGB-YCbCr conversion.

Since the human eye is much more sensitive to brightness contrasts than to color contrasts, an image of e.g. B. 720 x 576 pixels resolution - this corresponds to the usual image format of a DV camera (PAL) - the brightness information, which corresponds to the black / white portion, unchanged, but the color information is reduced to 360 x 288 pixels. Each pixel has its own brightness information, but four neighboring pixels share information about the red and blue components.

In a second step, each drawing file is broken down into square blocks. According to the above example of an image with 720 x 576 pixels, the color partial images are reduced to 360 x 288 points. Thus, a color partial image consists of 45 x 36 blocks of 8 x 8 pixels, the black and white image of 90 x 72 such blocks of 8 x 8 pixels. The blocks are processed in order from left to right and line by line from top to bottom, always the corresponding blocks from the SW image and the color images together. For an expedient representation, like the black and white image, the color partial images are divided into 45 x 36 units, each of which contains 16 x 16 pixels, or four blocks of 8 x 8 pixels.

This means that four software blocks, one color block (red) and one color block (blue) always belong together. These six blocks together form a unit, the so-called macro block.

In a third step, all of these macro blocks are compressed one after the other, line by line and each line from left to right, first the four software blocks, then the red block and the blue block. With this compression - this consists of the steps cosine transformation, which prepares a block for the subsequent quantization, and the final Huffman coding - most of the data reduction takes place.

This compression is lossy and it is therefore not possible to restore the original image exactly, but the loss of data is usually not noticeable compared to the original image. An image can be compressed to about 5% of the original amount of data without an excessive reduction in quality being discernible. With an even larger data reduction, however, the blocks in the image, for example, become visible.

An image compressed in this way is called an "intra-coded" image or I-image for short, the compressed data contains all the information necessary for decompression and display of the image. A further data reduction can be achieved by taking advantage of the fact that There are often only slight differences between successive individual frames of a video, for example the background often remains unchanged for several successive images, and only one or more objects have changed their position due to movement.

For this reason, for example, only every twelfth individual image is compressed as an intra-coded image in the manner described above, the remaining images are obtained by ascertaining the differences between the individual images. The determination of the differences, which is equivalent to a movement estimate, is only carried out on the software component. To do this, blocks are processed one after the other (namely 16 x 16 blocks, i.e. the four 8 x 8 SW blocks of a macro block) line by line from left to right.

A search area is defined, for example 16 pixels in each direction - horizontally and vertically. Within this search area, a 16 x 16 block is found in the next picture that best matches the 16 x 16 block of the previous picture. is If such a block is found, the position difference in the horizontal and vertical directions between the images form a vector, the so-called motion vector. Now it is sufficient to encode the motion vector and any small differences that may be present, which means that even less data is required for storage than with single-shot compression. If no suitable 16 x 16 block is found in the search area, then such parts of the image must be completely coded, the motion estimation does not work in these cases.

Pictures that have been coded from a previous picture by motion estimation are called P-frames. The motion estimation can also be carried out on the basis of the preceding and subsequent image, that is to say bidirectionally (“B frames”). As is clear from the foregoing, each I image contains the complete information for decompression, for which P and B However, you also need pictures of the neighboring pictures.

Usually the sequence of the pictures in an MPEG video is IBBPBBPBBPBBI ... .When playing the video you can "get in" with every I-picture, i.e. every 0.5 seconds at 25 pictures / second, because the I- The picture contains the complete information for decoding. The I-pictures are therefore also called support pictures or "key frames".

The motion estimation requires a great deal of computing power from the computer, which is why a video compression according to the invention “in real time”, that is to say while the camera is running, is only now possible with a software solution on a data processing device.

The above method describes the compression of video data according to the MPEG1 standard. However, there are also newer MPEG standards, such as MPEG2 or MPEG4, which basically work in a similar way. The differences should not be dealt with here, since these are known to the person skilled in the art and the essential ideas can be seen from the above.

System stream: An MPEG file that contains both video and audio data is referred to as a "system stream". The audio data is usually compressed to MP2, a process similar to the well-known MP3 process, but simpler. However, the audio data can basically also be compressed in MP3 or an even simpler method such as MP1.

The data is broken down into packets, each containing video or audio data. The packages usually have 2 kilobytes each. Each package contains a header with information nen about

• the type of data using an identification code with a length of 4 bytes, eg. B. 000001 cO (hexadecimal) for audio data, or 000001 eO for video data),

• the length of the packet (the next 2 bytes), as well

• Time stamps (a few bytes, different), which indicate the time for the output of the decoded video / audio data and the time for the decoding of the data of the corresponding packet and ensure the synchronization of the video and audio data during playback.

Then the actual audio or video data follows. When playing back, these packages are put together with a program part of the playback software, the so-called “demultiplexer”, to form coherent audio and video data and are played back synchronously.

It is now also possible to use other data, e.g. as according to the invention, also to collect measurement data in data packets and to insert them into this system stream when stored. These contain their own identification codes, for example their own

4-byte identification codes in the header so that they are recognized as measurement data packets. For example, the codes 000001 bd and 000001 bf are available.

Digital video format ("DV" format): According to the invention, video data coming from the digital camera, for example in digital video format, is decompressed in order to be able to display it continuously on a computer monitor.

In a commercially available DV video camera, the image data are compressed by means of a chip contained therein for storage on tape or another storage medium, using a method which is similar to the MPEG compression method; however, each image is compressed as a single image and no motion estimation is carried out.

The details of the DV format are specified in the DV standard document IEC 61834 of the International Electrotechnical Commission, which emerged from the "Blue Book" (Specification of ConsumerUse Digital VCRs using 6.3 mm magnetic tape). The details of the transmission of the video / audio data The IEEE1394 interface specifies the standard IEC 61883. The audio data, after it has been digitized in the video camera, is transmitted uncompressed (for example, 48 kHz sampling rate). Furthermore, the decompressed video data vid is immediately compressed again, e.g. B. in the format MPEG (1, 2, or 4) or in another format. The audio data is also subjected to compression (e.g. MP2, MP3 etc.). Data packets are formed from audio, video and measurement data, which are put together to form a system stream.

In principle, it would be possible to use the DV format for storage on the storage device, but this is not very useful since the relatively low compression rate means that too much storage space is required.

The invention offers several major advantages. On the one hand, it becomes possible to save recorded video / audio data and simultaneously recorded measurement data in a common data file. On the other hand, this also results in a link between the video / audio data and the measurement data, so that it is easily possible to search the data file for specific events and then to play back the corresponding locations.

In the case of medical or therapeutic recordings, it is possible, for example, to examine the data file to determine whether the blood pressure, pulse, heart rate, oxygen saturation of the arterial blood, etc. exceed or fall below a certain value or range of values, and can then determine the corresponding video / audio sequences view immediately, so that it is easy and quick to find certain places in the recordings. In addition, for example with MPEG compression, it is also possible to search the video data for a high proportion of motion and then display it together with the measurement data.

The invention is ideally suited in psychotherapy or in sports medicine and physicotherapy for (documentation of the therapy progress and for movement analysis. Furthermore, the documentation of operations with simultaneous video recording of the operation and the physiological parameters important for anesthesia such as ECG, oxygen saturation, blood pressure, etc Space-saving archiving of the recorded data on CD-ROMs or DVDs ("Digital Versatile Disc") is also possible.

However, the invention is not only limited to use in psychotherapeutic sessions, the system according to the invention can also be used in everyday medical practice, for example for documentation (operating room recordings, sports medicine), advanced diagnostics (e.g. sleep laboratory), follow-up checks such as documentation of the Fortsehnt- tes and therapy or training compared to the initial values, but also compared to standard values.

Another area of application is in neurology, for example in the area of video EEGs for seizure evaluation. A patient is monitored 24 hours a day using EEG and video with additional observation by a supervisor such as a nurse or a doctor. The recorded data is currently stored separately on the hard disk, evaluated and the seizure-free data is discarded after review. With the present invention, on the other hand, all data can be stored in a file, and it is also possible to use markings, for example, to specifically identify the seizures (e.g. epilepsy) so that they can be easily evaluated and viewed later.

In addition, data can be exchanged between different medical professionals etc. using powerful data connections such as broadband internet and their opinions obtained on a specific case.

However, the method according to the invention and the system according to the invention are not limited to medical or therapeutic use, but can basically be used over a very wide area. For example, it is also possible to record any physical or chemical measurement data together with audio / video data, for example to record a combustion process optically (for example also in the infrared range) and to detect chemical substances measured and released during combustion and correspondingly as measurement data in the data file.

For the sake of simplicity, a video camera and a measurement data recording device were mostly used in the above description. Of course, several measurement data recording devices can and will often be connected to the computer, and it is also quite conceivable for video data to be recorded by several video cameras; For example, one video camera can record in the optical range, another in the infrared range, but several optical cameras can also simply record from different camera positions.

In addition, it should also be mentioned here that, of course, USB web cameras can also be used for the invention, as well as digital cameras which forward the video data to a computer in an uncompressed manner, for example so-called IEEE1394 digital cameras.
