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
The present invention relates to a kind of audio frequency and video treatment technology, relate in particular to a kind of audio-video frequency content family sharing means.
Background technology
Due to the popularization of intelligent use at mobile terminal and television terminal, the local area network building that makes to found a family becomes possibility, and also making real time programme share becomes a kind of natural demand.But how on the basis of existing audio-video source equipment, to meet this demand, it is problem anxious to be resolved, for example, current each radio and TV operator also starts planning program in this respect and shares application, if redefine new product, at the one-way set-top box product used, will have major part to be eliminated, this is that the user is difficult to accept.
Summary of the invention
Based on the deficiencies in the prior art, the object of the invention is to propose a kind of audio-video frequency content family sharing means, can on the basis of existing audio-video source equipment, realize that real time programme shares.
The present invention is achieved in that a kind of audio-video frequency content family sharing means, comprising:
Input module, for receiving and process the audio-video signal of source device;
Coding module, encoded for the audio-video signal to input module received and processed;
Package module, encapsulate in real time for the audio-video signal to after coding, forms audio-video document;
Sharing module, for the audio-video document after encapsulating by network sharing to exterior terminal, receive the control command that exterior terminal sends simultaneously;
The remote control reception module, the remote signal of sending for the reception sources appliance remote control;
The remotely controlled module, for passing through the remote control key of remote control reception modules learn source device remote controller;
The remote control modular converter, be converted to for the control command that sharing module is received the remote control key that the remotely controlled module is learnt;
The remote-transmitter module, launch for the remote control key that the remote control modular converter is changed, and controls the operation of source device.
The invention has the beneficial effects as follows: from technical scheme of the present invention, can find out, the audio-video signal of audio-video source equipment output is after the coding and encapsulation of this sharing means, just can realize in real time by network sharing to exterior terminal, and exterior terminal also can carry out control operation to source device by this sharing means, therefore very convenient.
The accompanying drawing explanation
Fig. 1 is device architecture figure of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As Fig. 1, illustrated device architecture figure of the present invention.
The Set Top Box of now take describes as example, other audio-video source equipment, and for example DVD player is similar.
The RCA audio-video signal of Set Top Box output is the CVBS signal, complex tone vision signal for simulation, therefore also need to comprise the A/D analog-to-digital conversion module in input module of the present invention, the analog audio-video signal for the treatment of input, be converted into digital audio-video signal.
Select the TVP5150AM1 chip of Texas Instruments company for video modulus A/D conversion chip, this chip can receive NTSC, PAL and SECAM vision signal are also exported 8-bit ITU-R BT.656format digital signal, and this chip is controlled by I2C by master chip.Adopt the CS5343 chip of Cirrus Logic company for audio frequency modulus A/D conversion chip, this chip can convert simulation LR left and right audio signal to 24bit I2S digital audio and video signals.Master chip adopts sea to think the Hi3716C chip, and this chip can receive the digital signal that above-mentioned two chip produces, and by encoder, Video signal encoding is become to H.264 form, and audio-frequency signal coding becomes the AAC form.Pass through package module, encode out H.264 with the ES data of AAC and at first be packaged into audio frequency and video PES for the PTS information of synchronizeing, audio frequency and video PES is packaged into * .flv form memory mapped file through packing again, then carry out real-time sharing by http protocol in family lan inside through DLNA, DLNA, it is DLNA, by Sony, Intel, Microsofts etc. initiate to set up, be intended to solve individual PC, consumer appliances, mobile device interconnects interior wireless network and cable network, make the unconfined shared and growth of Digital Media and content service become possibility.Wherein audio frequency and video encapsulation and sharing module are considered cross-platform transplanting, accomplish to be independent of platform, can carry out cross-platform transplanting.Exterior terminal just can carry out the program broadcast by the player of supporting DLNA.
Exterior terminal, when having inquired this audio-video document sharing service and provide, calls terminal player and is broadcasted.
Control command is after exterior terminal sends to audio-video frequency content family sharing means, and this audio-video frequency content family sharing means is converted to corresponding control command the remote controller key of the correspondence of having succeeded in school, and source device is controlled.
For the user, certainly first to possess home LAN, then by the remotely controlled module, the remote controller of source device is learnt, so just can utilize and support that the exterior terminal of DLNA standard is watched, and can carry out control operation to source device.
The advantage of the embodiment of the present invention is to support on the market existing high standard definition Set Top Box, DVD player etc. with the various device of RCA audio-video interface, reaches program in real-time sharing equipment and the purpose of other audio-video frequency contents.Simultaneously, the also demonstration demand of the smaller screen terminals such as enough PAD panel computers, mobile phone of SD source.
