Abstract

The receiver (10) has a memory (24) storing meta data set beyond a duration of a respective image or tone broadcast. An actuator (22) is connected with a memory controller (20), and is activated by a user. The controller is formed such that activating of the actuator during reproduction of the respective image or tone broadcast causes storing of the metadata set corresponding to the image or tone broadcast in the memory. The memory includes additional information received by a broadcast receiving unit (14) during the broadcast. Independent claims are also included for the following: (1) a reproducing unit for reproducing image or tone broadcasts (2) a computer program product comprising instructions for defining an interface to a work database.

Description

The The invention relates firstly to a broadcast receiver for Receiving picture or sound transmissions, the same time a playback device for such Picture or sound, as well as a device for reproducing and / or sound works, which has no broadcast receiver, but with a database for Picture or Tonwerke is to be connected. Moreover, the invention relates a computer program product for such a playback device.

Of the broadcast receiver affected by the invention is capable of being next to an actual picture or sound transmission also additional information to receive that to a respective received image and / or Tonwerk correspond. Such broadcast receivers are for example digital audio Broadcast (short: DAB) receiver. In addition to DAB receivers but are also z. B. modern analog radio receivers, such as z. B. car radios are designed to be next to an actual image or sound transmission to receive additional information. Also receiver for cable television or cable radio are common Broadcast receiver because they do not specifically receive transmissions directed to an individual device and thus receive from typically addressed broadcasts Devices, which are connected to the Internet, differ.

Of the Invention is based on the experience that in particular radio listeners example while a car ride - often music tracks Listen, who do not know you, but you like them spontaneously. Only in rare make the songs are called so that the radio listener does not White, what he belongs Has. Therefore, it is especially for such radio listeners, who do not maintain intensive contact with the music scene, to identify a work that you have heard by the way. The invention has for its object to solve this problem.

According to the invention Task solved by that a broadcast receiver for analog or digital broadcasting, which is capable, in addition to audio and / or visual broadcasts also to receive additional information, in addition to its usual Components, namely a playback unit connected to a receiver in the strict sense is also a memory in which one to a certain Sound and / or image transmission corresponding Metadatensatz, which includes at least some of the received additional information, also on the Duration of reception of a respective picture and / or sound transmission can be stored. About that In addition, the broadcast receiver according to the invention also has a trigger to be operated by a user, for example a push button which is connected to a memory controller, thus formed is that activating the shutter during playback of a respective picture and / or sound transmission, a save of this Image and / or sound transmission belonging Metadatensatzes in the memory results.

With the respective, stored due to the activation of the shutter Metadata records, is a later one Identification of a specific image and / or sound works possible.

Further information are transmitted in analogue broadcast stations via various RDS (Radio Data System Services) services. In digital broadcasting, such information is provided via appropriate Transferring services to the recipients and can be stored if necessary.

Though It is foreseeable that in future more and more broadcasters will use their program transmitted to digital broadcasting, (also because the transmission via digital Broadcasting a higher transfer rate allows) however, the present invention is readily included Use of analogue broadcasting applicable.

From the additional information provided to a receiver via the RDS analogue radio data system to disposal are asked for the present invention in particular the information about the Services "Programs Service Name "(PS)," Program Identification "(PI)," Radio Text "(RT) and" Clock Time "(CT) transfer are suitable for storage as a metadata record to a later identification of image and / or sound works based on the stored metadata to enable.

Of the Service "Programs Service Name "(PS) becomes used by many stations to the sender name as additional information to those receiving devices, transferred to the for the reception of RDS data are formed.

Of the Service "Program Identification "will used by radio stations, a transmitter-specific four-digit To transfer hexadecimal number, with which a unique identification of a transmitter is possible.

Of the Service "Radio Text "(RT) becomes used by some broadcasters to provide certain additional information, such as transferring the current music track.

Of the Service "Clock Time "(CT) is used by some broadcasters to transmit the current prehistoric times for example, to synchronize a watch connected to a receiver.

From the over digital broadcasting additional information provided is particularly suitable for which by means of "Dynamic Label Service "(DLS) or" Multimedia Transfer Object Transfer Protocol (MOT) become.

The "Dynamic Label Service "(DLS) is with the service "Radio Text "(RT) of analogue broadcasting comparable and transmits z. B. Information such as the name of the artist and the name of the artist Track.

The "multimedia Object Transfer Protocol "(MOT) is a protocol that uses the push-broadcast method arbitrary Files are transferred to a receiver in a unidirectional connection can, so also files, with which a later identification of the desired Picture and / or Tonwerks possible is. Also the transmission a desired one Tonwerks itself, or at least part of it is possible via MOT.

About which Data service for later identification transfer necessary files be, is for the principle of the invention of secondary importance. So be z. For example, in North America, other standards for the transmission of additional information used, as in the EU. The only thing that matters is that after activating the shutter button into the memory such information in the form of a metadata record be saved with which at a later date a unique Identification of the respective image and / or sound works is possible.

According to one special embodiment The invention includes the metadata record as additional information the name of a piece of music and the name of the artist. With this two information is one latter Identification of the piece of music very easy. This information is, as already mentioned above by some stations z. B. over the radio data system RDS with the help z. B. the "Radio Text" service or at digital broadcasting via "Dynamic Label Service" (DLS) in addition to actual Transfer picture and / or sound works. However, the information "name of the artist" and "name of the artist Piece of music "not yet transmitted by all transmitters as additional information, so that a later identification of the desired Picture and / or Tonwerke not always possible is if exclusive this two information (if any) are stored.

According to one further and particularly preferred embodiment variant includes the Metadata record a time information and a sender identifying Information. With the help of this two information is a later identification of the piece of music always possible. All stations need namely, already for copyright reasons for each Tag a playlist, in which the music played on that day and whose transmission times are stored. Most of these will be Lists from broadcasters to collecting societies, such as the GEMA forwarded to obtain a copyrighted permission to play. About the Collecting societies can use this way with a broadcaster Information the playlist associated with a sender is determined and with the time information within this playlist the appropriate picture and / or Tonwerk can be found.

In front All sender-identifying information is nowadays of transmitted to almost all stations by means of appropriate data services. In this respect stands during of receiving and playing a particular picture and / or picture Tonwerks constantly one transmitter-identifying information is available and can be used as required Activate the shutter button be stored. Even the current prehistoric times are of some, but not all transmitters. If such transmitted by the transmitter Time information at the time of the desired saving not available is, can according to one particularly preferred embodiment also a time information is stored, which, for example from one to the broadcast receiver associated clock comes. Such a variant works even if a station set at the moment of saving is used does not transmit time information to the receiver. Preferably, a clock for providing an accurate time information adapted to regular intervals in time to be synchronized. Provides reliable time information in this context, the use of radio-controlled clocks. A time synchronization but also with the help of the "clock time" service of the radio data system RDS transmitted Time information or with the help of a comparable service of digital broadcasting Time information take place.

When Memory come in different variants of storage in question, and Although in each case preferably semiconductor memory, for example so-called flash memory containing a stored information as well then keep, if there is no external voltage at the memory.

The memory is preferably designed so that it can be removed from the broadcast receiver. Suitable memory for this purpose are, for example, so-called USB sticks or so-called SD cards (secure digital cards). These are currently the most common types of storage. In addition, a person skilled in the art knows a large number of people terer suitable memory known, such as XD cards or Compact Flash cards (CF cards). It is foreseeable that the future will bring further removable memories suitable for the present invention.

The same applies accordingly for sculptures. This opens up System allows the relevant providers the opportunity to completely new shoppers for musical works to open up. Allows the user the system casually perceived Identify works and at a later date, if they the user still likes to purchase.

Various variants The invention will now be in the context of the following description Reference to the figures closer be explained. From the figures show:

1 : a broadcast receiver having a built-in metadata record storage connected to a wireless data interface;

2 : an alternative broadcast receiver having removable storage (a storage medium) for work title metadata records; and

3 : a sound and / or image reproduction apparatus that automatically responds to a storage medium having stored thereon metadata about titles of sound and / or images.

1 shows a broadcast receiver 10 comprising the usual components of a conventional radio receiver, namely a broadcast receiving unit 14 , at whose one output an amplifier 16 connected, in turn, with a playback unit 18 connected in the form of a screen and / or a speaker. In that regard, the broadcast receiver corresponds 10 For example, a conventional car radio. Like many of today's standard car radios, the one shown here has broadcast receivers 10 also a clock 15 on.

In the 1 shown receiving unit 14 is designed to receive in addition to the information of the actual audio and / or video broadcast also - if available - additional, sent by a station information.

In addition to such, usual for a car radio components, assigns the broadcast receiver 10 in particular a memory 24 in which multiple metadata records can be stored beyond the duration of a respective audio or video transmission.

A metadata record comprises information, which is provided as additional information from a sender to the broadcast receiver 10 have been transferred. This information can be used to later identify each received image and / or sound.

To trigger a saving of a metadata record during a running audio or video transmission is a trigger 22 in the form of a push button provided with a memory control unit 20 communicates. The memory controller 20 causes certain additional information to be stored during the current reception of a sound or image. In addition to the radio reception unit 14 is the storage controller 20 with the clock 15 connected. In the embodiment shown here, it is provided that upon actuation of the trigger 22 both the additional information transmitted by a transmitter and that of the clock 15 output current prehistory as information of a metadata record in the memory 24 be stored. The embodiment variant shown here can either be designed such that the largest possible number of additional information is stored as a metadata record in order to save, if appropriate, the name of the artist and the name of the image and / or sound unit - if transmitted by the sender - or can be designed for this purpose to store a minimal amount of information as a metadata record, but sufficient to allow a later identification of the particular tone work. If only a small amount of information on the memory 24 is to be stored, it is advantageous to save only the station name or a transmitter-identifying information and the current prehistoric time as a metadata record. As already described above, these two pieces of information are sufficient to enable a later identification of the sound and / or image work. In addition, the availability of this information is particularly reliable

To the memory 24 from outside the broadcast receiver 10 It is a wireless data interface 26 with its own antenna 28 intended. The wireless data interface may be, for example, a Bluetooth transmitter / receiver.

In the operation of the broadcast receiver 10 this receives via its antenna 12 with the help of the receiving unit 14 a broadcast, such as a sound and / or video broadcast. That of the receiving unit 14 received and possibly decoded signals are at an output of the receiving unit 14 available and used by the amplifier 16 so amplified that they are beyond the playback unit 18 , So for example, the speaker of the broadcast receiver to be played.

While this is happening, a user may then, for example, if he likes a piece of music being played very well, the present in the form of a push-button trigger 22 trigger. This causes the memory controller 20 storing additional information corresponding to the currently received sound or image work as a metadata record in the memory 24 causes. By pressing the shutter button 22 causes the memory controller 20 of the broadcast receiver shown here 10 both storing the from the broadcast receiving unit 14 received additional information, as well as a saving of the clock 15 output current time in the memory 24 ,

Reading the memory 24 where the metadata is stored can be done, for example, by having a mobile device with a compatible wireless data interface 26 , for example, also a Bluetooth interface, in the vicinity of the broadcast receiver 10 is brought and according to the respective interface standard automatically connect to the wireless data interface 26 of the broadcast receiver 10 builds. The mobile device is in that case preferably designed so that it automatically after connection establishment of the memory 24 of the broadcast receiver 10 reads.

2 shows an alternative embodiment of a broadcast receiver 10 ' in which the memory for storing the metadata sets is not fixed, but in the form of an exchangeable storage medium 32 present, which in a corresponding read / write unit of the broadcast receiver 10 ' is to use. The storage medium can be, for example, a USB stick known per se or a likewise known per se SD card.

To put on a storage medium 32 To use stored metadata sets is a programmable player 40 provided, in addition to a central unit 42 a reading unit 44 for the storage medium 32 and having a playback unit 46 and an input unit 48 Is provided. The playback device 40 is designed to automatically respond to when a storage medium 32 into the reading unit with metadata records identifying work titles 44 is used. Once this is done, the playback device lists 40 to those on the storage medium 32 stored work titles belonging to stored metadata records on the playback unit 46 on. A user can then use the input unit 48 Select some or all of the titles in order to have a short look at the corresponding works and, if necessary, to buy the corresponding works. Because the playback device 40 is able to on the storage medium 32 To display the work titles belonging to stored metadata records is the playback device 40 over the internet 50 with a works database 60 in which the work titles for the respective metadata records are stored.

In a preferred embodiment, in which the purchase of a respective work on the playback unit 46 is possible, the purchase of such a work in a known manner also takes place via the Internet 50 ,
