Embodiment Construction

[0027] The invention will be described in more detail hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. In the drawings, the same reference numerals denote the same or similar components or elements.

[0028] figure 1 It is a schematic diagram of an application scenario 100 according to an embodiment of the present invention. The application scenario 100 includes a live broadcast source 102 , a live broadcast transfer system 104 and a target streaming media server 106 .

[0029] The live broadcast source 102 can come from the Internet, a mobile phone terminal or a TV network, and the format can be P3G, RTSP, RTMP or ASF, etc.

[0030] The live broadcast transfer system 104 can perform protocol and format conversion on different input live broadcast sources. Since various terminals are generally required to support the RTSP protocol and the HTTP protocol, in one embodiment, the target streaming media ser...

Abstract

The invention provides a direct broadcast transfer method and a direct broadcast transfer system which are used for fusing screens of a television, a computer and a mobile phone and relates to a streaming media encoding and decoding technology. The direct broadcast transfer method for fusing the screens of the television, the computer and the mobile phone comprises the following steps of: receiving direct broadcast stream data transmitted from a direct broadcast source; detecting an encoding format of the direct broadcast stream data; transcoding the direct broadcast stream data which is inconsistent with a preset target protocol in real time according to a detection result; and transmitting the direct broadcast stream data which accords with the target protocol to a corresponding target streaming media server. According to one aspect of the invention, by the direct broadcast transfer method, different direct broadcast sources which are generated by encoding or exist on a network can be subjected to protocol and format conversion in real time; therefore, play requirements of computers, set top boxes, mobile phones and other various terminals are met, and fusion and interaction of the screens of the television, the computer and the mobile phone are effectively supported.

Description

technical field [0001] The present invention relates to streaming media encoding and decoding technology, in particular to a live broadcast transfer method and system. Background technique [0002] The integration of three screens (TV, computer, mobile phone) is a key step in the promotion of triple play. With the start of the integration of three networks (television network, broadband network, and telecommunication network), three-screen integration and three-screen interaction have become streaming media. App development trends. Live streaming is an important part of the streaming business. The live broadcast source can be a live stream captured by a camera, or an encoded media stream existing on the network. The former can be an AV signal, which needs to be encoded before it can be served by the streaming media server; the latter can be relayed and provided with services as long as the streaming media server supports this format. [0003] The transmission protocols, e...
