Transmission method, receiving method and corresponding device for distribution system and media data

Abstract

The invention discloses an issuing system, a delivering method, a receiving method for media data, and a corresponding device, which makes the media data of different media format compatible in the identical system. The technology includes: the delivering end acquires the positioning information and URL uploaded by the receiving end; determine the media file by using the URL, and according to the medial format corresponding to the file type of the media file, find the application interface corresponding to the media format; acquire the index information of the media data of the corresponding media format by using the application interface; acquire the corresponding the media data of the media format according to the index information and the positioning information; transmit the media data of the media format; the receiving end finds the application interface corresponding to the media format according to the media format needed by users, and uploads the positioning information and the URL of the media data needed to be downloaded via the application interface; acquire the media data returned by the receiving end according to the uploaded positioning information and the URL.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a media data distribution technology. Background technique [0002] With the rapid development of network applications and the gradual improvement of network bandwidth, a large number of network media applications, especially network multimedia applications, appear, and these applications can be sent to different user terminals through the network. [0003] In the prior art, the multimedia data (image and sound, etc.) of the program are stored in the streaming media server, and the user can watch and listen to the program while downloading the program by accessing the streaming media server, without the need to read the program in the entire program. Multimedia files can only be viewed and listened to after the download is complete. Streaming media technology provides real-time high-quality video and audio effects in a low-bandwidth environment. However, there are various form...

Problems solved by technology

However, there are various formats of network streaming media. For example, the mainstream formats of streaming media include Microsoft’s wmv format, Real’s rm and rmvb formats, and flash animation formats. The media data in these formats are incompatible with each other.

[0004] Media data in different media formats are incompatible in the same network media publishing system, that is, network media operators can only choose one format of media data to send, which greatly limits the flexibility of operators in selecting content, or requires Different formats must be transcoded before sending, which greatly increases the complexity of sending media data

The incompatibility of media data in different media formats in the same system brings great technical difficulties to business expansion, and cannot adapt to the rapid development and diverse needs of network services

Network media operators can only purchase different network media publishing systems for different formats and business applications, which greatly increases the cost of investment
