Abstract
The utility model discloses a set-top box. A main chip (1) of the set-top box respectively transmits signals with an internal memory module (2) and a flash memory hard disk (3) mutually. A network interface (6) and a digital audio frequency interface (11) are connected on the main chip (1) of the set-top box which transmits signals to a video frequency module transformer (7) and an audio frequency module transformer (8). A power supply (4) provides power to the main chip (1) of the set-top box. The set-top box displays video and audio frequency programs on TV, which realizes the real-time visible communication.
Description
Technical field
The utility model relates to set-top box, especially relates to integrated many decoded videos broadcast reception of a kind of monolithic and real-time communication set-top box.
Background technology
At present, the problem of broadcasting and TV set-top box on the market or the technical existence of video telephone has: 1, multicasting technology imperfection; 2, network accessibility deficiency.
The utility model content
The purpose of this utility model provides and a kind of video-audio program is shown by television set, realizes the TV set-top box of real-time Visual communications.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of set-top box, set-top box master chip transmission signals mutually respectively and between memory modules and the flash memory hard disk, on the set-top box master chip, be connected with network interface and digital audio interface, set-top box master chip transmission signals is given video A-D converter and audio frequency A-D converter, and power supply provides power supply for the set-top box master chip.On the set-top box master chip, be connected with USB interface.On the set-top box master chip, be connected with the IC-card deck, on the set-top box master chip, be connected with infrared receiving device.
This set-top box receive " utilize video camera, video camera, recorder and other to look audio frequency production equipment and take, record, but the video-audio program of forming by the image of continuous motion or the sound that can listen to continuously " and with " Internet protocol (IP) as main carrier, utilize the television set of common or high definition to make the receiver of display terminal; And combine real-time visual communication function.Set-top box utilization maturation, reliable Internet Data Transport Protocol come the transmission tone video compression data, utilize the monolithic TI chip decoding audio, video data of high integration in the set-top box, can realize low code check H.264, AVS, H.263, G711, G729, MPEG-2, MPEG-4 decoding, reach the image quality of QCIF, CIF (352 * 288) and D1 (720 * 576) resolution.Same principle realizes the real-time communication function of video telephone simultaneously.
The design of the utility model set-top box is based on the structure of multimedia digital signal processor, adopt high-performance digital signal processor and embedded system chip as hardware platform, adopt the multimedia digital processor structure can realize various video and Audio Processing easily, also support other to be used for the encoding and decoding standard of IPTV simultaneously.The utility model set-top box has solved on same set-top box the decoding capability to multiple audio/video coding, expanded adaptive capacity to audio/video server, for implementing decoding to multiple audio/video coding, master chip has adopted the arm processor of the high performance TI band DSP of company function, the LINUX operating system of the excellent performance in the transplanting well solves the contradiction of understanding on code requirement and the decoding performance; And additional video telephone function, can be real-time carry out visual communication, the space on the business demand of expansion may for what increase that value-added service provides future.The utility model set-top box can not only be decoded to the video source of H264, MPEG-2, MPEG-4, H263, WMV coding, has also added AVS decoding nuclear in AVS encoded video source, and has realized the set-top box of several above video source of monolithic chip decoding.
Description of drawings
Fig. 1 is an electrical block diagram of the present utility model.
Embodiment
The structure of a kind of set-top box of the utility model is as shown in Figure 1: set-top box master chip 1 transmission signals mutually respectively and between memory modules 2 and the flash memory hard disk 3, on set-top box master chip 1, be connected with network interface 6 and digital audio interface 11, set-top box master chip 1 transmission signals is given video A-D converter 7 and audio frequency A-D converter 8, and power supply 4 provides power supply for set-top box master chip 1.On set-top box master chip 1, be connected with USB interface 9.On set-top box master chip 1, be connected with IC-card deck 10.On set-top box master chip 1, be connected with infrared receiving device 5.Above-mentioned video A-D converter 7 and audio frequency A-D converter 8 can adopt commercial device.
In Fig. 1, the set-top box master chip adopts the ARM chip of TI company, and this chip has a powerful dsp processor, and the decoding software kernel has well been finished the decoding task of the audio frequency and video of multiple coding in DSP; Set-top box is made up of many peripheral interfaces: audio-video interface (digital audio interface 11) adopts S terminal and AV terminal, can the most television sets of adaptive present China.Expansion interface comprises USB interface, can connect the USB phone, as the video telephone accessory; Network interface connects the internet network; The IC-card interface is as the authentication of charge pay per view; Infrared remote control, infrared remote control can use hand-held remote controller or use infrared keyboard that set-top box is controlled.
