Abstract
The invention discloses whole multi-media audio and video adaptor software which is composed of a digital audio and video conversion module, motion picture experts group (MPEG) 4 codes (digital signal processor (DSP) core) and a port control module. An input port and an output port are formed in the port control module. The digital audio and video conversion module and the MPEG 4 codes (DSP core) are characterized in that multiple coded formats converting software is adopted, audio and video signals in multiple formats are converted into signal formats admitted by management center software. A single chip embedded type system with the DSP core has the advantage of achieving the following functions: media formats such as VCD, MP3, DivX, AVI, WMV, WMA, RM and RMVB are converted into file formats admitted by a system, so that the files can be played; multiple accessing manners are supported such as a network and a digital television; long-distance video-on-demand and a self-adaptation network bandwidth transmission function are achieved, and the media transmission code rate can be adjusted according to practical situation of the network.
Description
Technical field
The present invention relates to multimedia technology, relate in particular to multimedia audio-video transducer software engineering.
Background technology
At present, the most domestic multimedia network system all can provide video request program and live function, but domestic production interchange device software is not the solution of correspondence with it of the different traffic transmission rate below 2M, below 16M or below 100M for network speed, audio/video on-demand device response speed is not high, extensibility is not high, serve very unstablely, resource format is compatible to be lacked.
Summary of the invention
Purpose of the present invention is exactly in order to overcome above-mentioned weak point of the prior art, a kind of complete multimedia audio-video adapter software is provided, realize that resource management is convenient, Operation and Maintenance purpose simple, stable and reliable for performance, become extensibility strong, look the video on-demand system that audio format is extensively supported, cost performance is high.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of complete multimedia audio-video adapter software, formed by digital audio/video modular converter, MPEG4 coding (DSP core), interface control module, described interface control module has input interface and output interface, and input interface has cable interface and digital television signal line interface; Output interface mainly contains netting twine, USB interface, audio frequency and video output line, described digital audio/video modular converter and MPEG4 coding (DSP core), it is characterized in that: adopt the software between the Multi-encoding format conversion, the audio-video signal of multiple format is converted to the signal format that administrative center's software is admitted, adopt the single-chip embedded system of DSP core, the multiple audio frequency and video of this technical support and picture format input; Support various audio frequency and video input signals, comprise channel decoding, solution device, demodulator, the transmission stream decoding frequently of digital television signal; The various forms that comprise video decoder: MPEG-2/4, H.264/AVC, VC-1, WMA ... Deng; Comprise the functions such as video/audio output unit, Audio and Video digital analog converter.On the network technology of audio frequency and video propagation and program request; remove outside management, broadcasting and the program request based on the B/S distributed network; also comprise the digital watermarking encryption technology; enter the authentication management subsystem of server, realize copyright management, information safety protection and media push host-host protocol (MPTP)----media content, programme and real time information and control information.
The invention has the beneficial effects as follows: can realize following functions: with VCD, MP3, DivX, AVI, WMV, WMA, RM, the file format that the media format conversion such as RMVB become system to support is for broadcast.And support plurality of access modes, for example network, Digital Television.Realize remote on-demand, the network bandwidth adaptive transfer function can be regulated the media delivery code check by the network actual state.
Embodiment
The invention will be further described with an embodiment for the below:
A kind of complete multimedia audio-video adapter software, formed by digital audio/video modular converter, MPEG4 coding (DSP core), interface control module, described interface control module has input interface and output interface, and input interface has cable interface and digital television signal line interface; Output interface mainly contains netting twine, USB interface, audio frequency and video output line, described digital audio/video modular converter and MPEG4 coding (DSP core), it is characterized in that: adopt the software between the Multi-encoding format conversion, the audio-video signal of multiple format is converted to the signal format that administrative center's software is admitted, adopt the single-chip embedded system of DSP core, the multiple audio frequency and video of this technical support and picture format input; Support various audio frequency and video input signals, comprise channel decoding, solution device, demodulator, the transmission stream decoding frequently of digital television signal; The various forms that comprise video decoder: MPEG-2/4, H.264/AVC, VC-1, WMA ...
