Embodiment 1

[0038] refer to figure 1 , is a structural diagram of a streaming media acquisition and encoding service system according to Embodiment 1 of the present invention.

[0039] The streaming media collection and encoding service system mainly includes:

[0040] Signal collection module 11, for collecting original audio and video flow in real time;

[0041] Encoder 12 is used to encode the original audio and video stream into audio and video data, and provide it to the communication service module 13. During the encoding process, the probability of key frame occurrence in the audio and video data is adjusted in real time according to the network bandwidth;

[0042] The communication service module 13 is configured to split the audio and video data into network transmission packets and distribute them to the requesting end.

[0043] Among them, refer to figure 2 , the encoder 12 may further include:

[0044] An encoding module 21, configured to encode the original audio and vid...

Embodiment 2

[0070] refer to image 3 , is a structural diagram of a streaming media acquisition and encoding service system according to Embodiment 2 of the present invention.

[0071] The system includes three layers, the bottom layer is the system layer 1, including the hardware platform and the operating system and device drivers covering it, as well as audio / video acquisition equipment; the middle layer is the acquisition and compression system 2, mainly including signal acquisition Module, multi-channel encoder and communication service module; the top layer is the requester 3, such as live streaming engine, forwarding service and storage service, among which the storage service can be realized by the cluster storage server.

[0072] Wherein, the collection and compression system 2 is a very important component in the whole system, and its main function is to collect audio and video source signals, encode them into FLV formats with multiple bit rates, and send them to the live broadc...

Abstract

The invention provides an acquiring and coding service system of a streaming media, comprising a signal acquiring module, a coder and a communication service module, wherein the signal acquiring module is used for acquiring an original audio-video stream; the coder is used for coding the original audio-video stream into audio-video data, providing the audio-video data to the communication service module and adjusting the probability of a key frame in the audio-video data in real time according to a network wideband in the coding process; and the communication service module is used for splitting the audio-video data into a network transmission packet and transmitting the audio-video data to a request end. In addition, the signal acquiring module can acquire various paths of original audio-video streams from each video source in real time; and the coder can be used for starting various paths of codes from each video source in parallel, wherein each path corresponds to a code rate. The system can ensure the smooth playing of image frames and provide multiple code rates for users to selectively switch.

Description

technical field [0001] The invention relates to the technical field of streaming media, in particular to a streaming media collection and coding service system. Background technique [0002] The popularity of the Internet and the application of multimedia technology on the Internet urgently require technologies that can transmit media files such as video, audio, and computer animation in real time. In this context, streaming technology and streaming media have emerged. In layman's terms, streaming transmission technology means that when the video and audio server on the Internet transmits media files such as sound, image or animation from the server to the client in real time, the user does not have to wait for all the media files to be downloaded, but only needs to delay a few minutes. Seconds or ten seconds, it can be played on the user's computer, while the rest of the file is continuously received by the user's computer in the background until the playback is complete or...
