The beneficial effects of the utility model are: this high definition media player is owing to adopted EM8620 or EM8622 as the digital signal Media Processor, therefore can carry out video/audio decoding and output image form adjustment processing back output to the high definition media form more than the 720P (especially 1080P form), realized broadcast, simultaneously broadcast that also can compatible SD media formats to the high definition media form; Again because this player output interface not only has traditional component interface YPbPr interface line by line, also adopted HDMI high definition media interface, the digital signal that this HDMI interface solves EM8620 or EM8622 does not need to be converted to analog signal again but directly directly is sent to receiving equipment with digital signal, the video-audio signal that therefore can guarantee first water transmits, and has realized real high definition output; Simultaneously, its multiple input interface, can be connected with the high definition media format signal source of various ways, read its high definition media file, especially can interconnect with computer local network by the computer local area network interface, play the media file on the computer in real time, and can be by computer or directly be connected to the Internet by the URL uniform resource locator, browsing information or carry out the VOD video request program is realized the online broadcast of network.
Description of drawings
Fig. 1 is the theory diagram of the utility model high definition media player;
Fig. 2 a, Fig. 2 b are the structural representation of the utility model one embodiment.
Embodiment
With embodiment the utility model is described in further detail with reference to the accompanying drawings below:
As shown in Figure 1, this high definition media player comprises a digital media signal processing unit, and the unit comprises a digital media signal processor, and Add-In memory and data buffer.The digital media signal processor specifically adopts the EM8620 or the EM8622 chip of U.S. Sigma Design company, this chip has the decoding function of 1080P source signal, can realize that the high definition media file is (more than the 720P, especially high definition decoding 1080P), and can support present various main flow format digital media decodes, the form of decoding is a lot, main is a kind of new media formats WMV9 (VC-1) that can support that Microsoft releases, and .ts, .tp .mpg .vob, DivxHD (.avi), forms such as MPEG2.HD.
This high definition media player has three kinds of input interfaces, can receive the media signal of three kinds of interfaces, it is respectively: the USB general-purpose interface, concrete USB2.0 input interface, this interface is connected with the external USB memory device by the USB line, its USB memory device can be portable hard drive, USB flash disk etc., but the media file of this player recognition to the USB memory device stopped conversion of signals by the USB interface chip with the matchmaker who receives and become the pci bus signal to give the digital media signal processor; The DVD player core is put in this player DVD player in-core with high definition or common laser disc, is converted to the IDE signal by high speed DVD player core after to processing such as optical disc media file decodings, is sent on the digital media signal processor bus; Also has a local area network (LAN) RJ45 network interface, with netting twine local area network (LAN) RJ45 network interface and computer local network are interconnected, this player can carry out communication with the computer that computer local area is equipped with computer terminal 1080P high definition media player service software on the net, convert the media signal that receives to the pci bus signal by network interface chip and give the digital media signal processor, can play the media file on the computer thus in real time, and can be by computer or directly be connected to the Internet by uniform resource locator (URL), browsing information or carry out the VOD video request program has been realized the online broadcast of network.
This high definition media player has two kinds of output interfaces, and being used for decoded conversion of signals is that the standard pronunciation video interface signal of multiple form offers audio-visual equipment.Output interface is respectively high-quality digital interface HDMI interface (High Definition Multimedia Interface-HDMI (High Definition Multimedia Interface)) and analog interface YPbPr interface commonly used.The HDMI interface circuit receives 24 the RGB image digital signals and the synchronous I2S digital audio signal of digital media signal processor EM8620 or the output of EM8622 chip, and the HDMI high definition media interface signal that changes into pure digi-tal is exported to display devices such as HDTV (High-Definition Television), because the digital signal that the HDMI interface solves EM8620 or EM8622 does not need to be converted to analog signal again but directly directly is sent to receiving equipment with digital signal, the video-audio signal that therefore can guarantee first water transmits, and has realized real high definition output; Because this HDMI interface converts the parallel video-audio signal in decoding back to the HDMI signal output of serial, single line connects, while images signal and audio signal, interface transmitted image quality can reach more than the 1080P standard, and because single line output, and interface is small and exquisite, therefore connection and easy to use.The HDMI interface has the protection of HDCP high-definition content simultaneously, can effectively prevent the high-definition content copy, safeguards copyright.Interface also has user friendly utility functions such as hot plug, the control of CEC consumer electronics, EDID expanded scope recognition data.This player also is provided with analog interface YPbPr, as high definition color difference components vision signal, and S terminal light tone separation signal, CVBS composite video signal, and corresponding 5.1 passages or stereo (output of SPDIF digital audio is arranged simultaneously).As seen media player of the present utility model can both be suitable for different external display device by two kinds of different output interfaces and different external display device connections, can connect different external display device simultaneously again simultaneously.
