Abstract
The utility model discloses a high-density laser optical disk system which comprises the following components: a terminal input interface, a display device, a video decoder, a signal switching device and a terminal output interface. The terminal input interface is also connected with a multi-rail optical pickup which is connected with the signal switching device through the terminal input interface. The signal switching device is connected with the display device through the terminal output interface. The high-density laser optical disk system performs data reading analysis to a read disk through the multi-rail optical pickup connected with the terminal input interface, and furthermore outputs the read data to the signal switching device with a form of data flow. Finally the data flow is decoded by the video decoder is outputted to the display device through the terminal output interface. Compared with the prior art, through decomposing the data of the large-capacity disk for obtaining the storable data flow, playing the large-capacity disk by the high-density laser optical disk system is realized according to the utility model, so that the high-density laser optical system has stronger compatibility.
Description
Technical field
The utility model relates to a kind of EVD system.
Background technology
(the Enhanced Versatile Disk of EVD system, be called for short EVD), technical merit is better than DVD, highest resolution can reach 1920*1080, its audio encoding and decoding technique that adopts (EAC) can generate the audio frequency that is better than Doby AC-3 quality, and EVD also has flexible and changeable type matrix function and stronger interaction capabilities.
EVD supports common DVD video disc, and the CD capacity of single-surface single-layer is 4.7GB, and the single-surface double-layer capacity is 8.5GB.But and the CD capacity of HD DVD video disc single-surface single-layer is 15G, and the CD capacity of blue-ray DVD single-surface single-layer 25G is compared, and the capacity of the DVD video disc CD that EVD supported is too small, and the space of its expansion is very limited.
Calculate with 135 minutes full HD films, adopt the CD capacity that requires of MPEG2 compressed format to reach 20GB, MPEG4 compressed format to reach 12GB～15GB, and the capacity of EVD single-side double-layer light disk just has only 8.5GB.And according to the development trend of television video, the resolution of high-definition movie can be higher in the future, the size of video file also can be bigger, the CD capacity of EVD is more awkward then for that, the capacity of the video disc CD of therefore existing EVD system is too small, is difficult to satisfy the broadcast request of high-definition movie.
Summary of the invention
For addressing the above problem, the utility model provides a kind of EVD system, and this system can realize the broadcast of multiple high capacity dish.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of EVD system, comprise terminal input interface, display device, video decoded device, signal switching device shifter and terminal output interface, described terminal input interface also is connected with a multiple light picker, this multiple light picker is connected with the signal switching device shifter by the terminal input interface, and described signal switching device shifter then is connected with display device by the terminal output interface.
Also be connected with video decoded device on the described signal switching device shifter, by this video decoded device to decoding from the video signal of signal switching device shifter.
Described video decoded device also is connected with control panel.
The utility model carries out the data read analysis by the multiple light picker that the terminal input interface connects to the disc that is read, and the data that read are outputed to the signal switching device shifter with the form of data stream, wherein the signal switching device shifter can be stored these memorying data flows that reads, and finally by video decoded device data stream is decoded, output to display device by the terminal output interface.Compared with prior art, the utility model obtains storable data stream by the data of high capacity disc are decomposed, and has realized the possibility of EVD system plays high capacity video disc, makes the EVD system have stronger compatibility.
Description of drawings
Fig. 1 is a system chart of the present utility model.
Embodiment
For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.
See also shown in Figure 1ly, the utility model provides a kind of EVD system, be mainly used in solve multiple huge capacity compact discs disc the problem that can not play by EVD, as HD DVD video disc and blue-ray DVD video disc etc.
Native system mainly includes the multiple light picker, video decoded device, the signal switching device shifter, the terminal input interface, display device and terminal output interface, wherein said terminal input interface is connected with the multiple light picker, this multiple light picker is used to read outside optical disk data, and be connected with the signal switching device shifter by the terminal input interface, its data stream that reads is sent to the signal switching device shifter by the terminal input interface, and include a plurality of fifo buffers in the signal switching device shifter, be used to store these data stream, and the signal switching device shifter is connected with display device by the terminal output interface also.
Wherein the multiple light picker is used for from many tracks of CD reading of data and with the form output of each data stream data from every track; And, temporarily store above-mentioned data stream by a plurality of fifo buffers in the signal switching device shifter.Wherein the multiple light picker can selectively be exported the data stream that is less than the track of maximum track numbers that pick-up can read from quantity, a plurality of impact dampers in the general signal switching device shifter, these data stream that read are sent to video decoded device, video decoded device carries out decoding processing to these data stream, and decoded data are passed through the signal switching device shifter again carry out hand-off process, finally output to display device, show by the terminal output interface.
In addition, video decoded device also is connected with a control panel, and this control panel is by realizing video decoded device and being connected of signal switching device shifter, and can realize control to the display device output signal by it.
More than be that a kind of EVD provided by the utility model system is described in detail, used specific case herein structural principle of the present utility model and embodiment are set forth, above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
