Embodiment
In conjunction with accompanying drawing the utility model is done further explanation:
As shown in Figure 1, the seamless spliced decoding device of a kind of WirelessHD video comprises the video decode control unit that is used for audio-video frequency media code stream real-time decoding and control stream data allocations; With said video decode control unit communicate by letter be connected be used to gather the wireless of audio-video signal and cable network communication module; With the said video decode control unit HDMI interface that being used for of being connected dock with display unit of communicating by letter.
As shown in Figure 4, said video decode control unit comprises master cpu module and decoding CPU module, and said decoding CPU module all is connected with said master cpu module through the RTL8316 router chip.
Said wireless and cable network communication module comprises wireless signal receiver and RS232 communication interface, and said wireless signal receiver and RS232 communication interface all are arranged on the said master cpu module.
As shown in Figure 3, said decoding CPU module comprises decoding CPU and is arranged on internal memory DDR3 and the flash memory NANDFLASH on the decoding CPU.
As shown in Figure 2, said master cpu module comprise master cpu and be arranged on the master cpu internal memory, flash memory, microphone, audio amplifier and audio frequency to the record interface.
Adopt homemade panel computer chip A10 as the video decode control unit; Dock with media server or other multimedia code stream supply equipments through RS232 or wireless signal receiver; Dock through big screen display device such as one or more HDMI interfaces and television equipment; Through network collection to the audio-video code stream signal get into the video decode control unit and carry out audio/video decoding, and decoded image is outputed to corresponding HDMI interface, thereby reaches the usefulness that shows output.
