Abstract
The utility model relates to a digital video camrecorder with a USB storage medium, which comprises a micro-controller and a digital signal processor in a digital video camrecorder circuit, and a USB processing chip connected with a USB interface; the USB processing chip is respectively connected with the micro-controller and the digital signal processor. The digital video camrecorder has the advantages that the video recorded by the digital video camrecorder is directly stored in USB equipment, so that users can more conveniently copy and shift the recorded video images and the like, thus simplifying the video recording method of the users and providing more convenience for the users to operate and carry.
Description
Technical field
The utility model relates to a kind of digital video recorder, particularly a kind of digital video recorder with USB storage medium.
Background technology
In recent years, global Digital Video industry had kept annual quick growth rate more than a times.And the market growth of China is faster.Along with the fast development of digital vedio recording technology, people are more and more to the demand of digital video recorder, require more and more higher.High definition, big memory capacity, storage fast and easily such as play at the criterion that all more and more becomes the user.With regard to the storage medium of digital video recorder, the comprising of current main application: TAPE tape, CARD CD, built-in hard disk etc.But to duplicating and moving of the video content in these storage mediums but is a complicated slightly process.Such as: read the TAPE content and need use 1394; The CARD that has broken away from digital video recorder reads and then needs card reader.And for the video camera that uses built-in memory space, the mobile needs of contents such as video carry video camera itself just can carry out.These all are digital video recorder defectives to a certain extent for user for current requirement fast, easily.
Summary of the invention
The utility model provides a kind of digital video recorder of the USB of having storage medium in order to overcome weak point of the prior art.
The utility model for achieving the above object, the technical scheme of being taked is: a kind of digital video recorder of the USB of having storage medium, comprise microcontroller and digital signal processor in the digital video recorder circuit, it is characterized in that, also comprise the USB process chip that is connected with USB interface, described USB process chip is connected with microcontroller and digital signal processor respectively.
The beneficial effects of the utility model are: directly be stored in the USB device by the video with the digital video recorder typing, the user can duplicate more easily, the mobile video image of being recorded etc.Thereby simplified the method that the user moves institute's recorded video, more convenient user's operation is used simply, easy to carry, moves inconvenience or reads this problem of process complexity thereby solved the video camera storage medium.
Description of drawings
Fig. 1 is that circuit of the present utility model connects block diagram, and as Figure of abstract.
Embodiment
As shown in Figure 1, a kind of digital video recorder with USB storage medium, comprise microcontroller MICOM and digital signal processor DSP in the digital video recorder circuit, also comprise the USB process chip that is connected with USB interface, described USB process chip is connected with microcontroller and digital signal processor respectively.
By the CCD device vision signal video is collected in digital video recorder, MIC then gathers audio signal.Embedded digital signal processor DSP reprocesses the dedicated devices of processing with logical circuit to looking audio digital signals in the main frame, and it carries out after the processing such as certain conversion, identification signal being imported among each IC that is responsible for the AV signal codec specially to the AV signal that collects.Entering the USB process chip by the digital signal processor DSP transmission through the AV signal behind the signal codec, in this chip, can control institute's recorded video is stored in the USB medium, also can from the USB memory device, read and deposit content.In collection, processing, encoding and decoding and the associated transport process of AV signal, relevant IC is controlled by MICOM.
