Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 , which shows the structure diagram of the device of the present invention.

[0017] A set-top box is used as an example for description, and other audio and video source devices, such as DVD players, are similar.

[0018] The RCA audio-video signal output by the set-top box is a CVBS signal, which is an analog composite audio-video signal, so the input module of the present invention also needs to include an A / D analog-to-digital conversion module, which is used to process the input analog audio-video signal, and convert it to Convert to digital audio and video signals.

[0019] For the video analog-to-digital A / D conversion chip, choose the TVP5150AM1 chip from Texas Instruments, which can receive NTSC, PAL and SECAM video signals and output 8-bit ITU-R BT.656 format digital signals. The chip is controlled by the mai...

Abstract

The invention discloses an audio and video content family shared device which comprises an input module, an encoding module, an encapsulation module, a sharing module, a remote-control receiving module, a remote-control learning module, a remote-control conversion module and a remote-control emission module. After being encoded and encapsulated, audio and video signals of a source device are shared to an external terminal through a network, meanwhile a control demand sent by the external terminal is received and converted into remote-control key codes learned by the remote-control learning module, and the remote-control key codes control the operation of the source device after emission. The audio and video content family shared device can achieve real-time program sharing based on an existing audio and video source device.

Description

technical field [0001] The invention relates to an audio and video processing technology, in particular to an audio and video content family sharing device. Background technique [0002] Due to the promotion of smart applications in mobile terminals and TV terminals, it is possible to establish a home LAN network, and it also makes real-time program sharing a logical requirement. However, how to meet this demand on the basis of existing audio and video source equipment is an urgent problem to be solved. Most of the one-way set-top box products in use will be eliminated, which is unacceptable to users. Contents of the invention [0003] Based on the deficiencies of the prior art, the purpose of the present invention is to propose a home sharing device for audio and video content, which can realize real-time program sharing on the basis of existing audio and video source equipment. [0004] The present invention is achieved in this way, an audio and video content family sh...
