Problems solved by technology

In an actual operating streaming media business system, the media files in it can generally be in several different storage formats and encoding formats, and the encoding parameters are even more variable. Therefore, to ensure this premise, re-encoding is necessary, which aggravates the operation and management. The workload of personnel increases the requirements for the service performance of the system

Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] When the user plays the simulated live channel through the mobile terminal, the streaming media server forwards and distributes the media content to the mobile terminal according to the requested content. The media server uses the original RTSP (Real TimeStreaming Protocol real-time streaming protocol) to control the session instead of re-establishing a new RTSP session, and sends the session description information SDP (SessionDescription Protocol session description information) of the media file or live channel to be played through the ANNOUNCE message Actively push to mobile terminals. The SDP information includes all encoding formats, grades, grades, and related encoding parameter information of the media files to be played or the media tracks of the live channel, which can be compared with the encoding formats and paramet...

Abstract

The invention discloses an analog live broadcasting method of a mobile streaming media and a content switching method thereof; when the streaming media server detects the need of switching to another media file, the streaming media server utilizes the current real-time streaming protocol RTSP for controlling the session, and actively pushes the session description protocol (SDP) of the other media file to a mobile terminal; and the mobile terminal points out how to reuse the RTP / RTCP resource through the increase of corresponding parameter fields in the RTSP PLAY, and communicates with a media track about the replacement condition of the media track on an RTP link and corresponding RTP parameter adjusting information. The invention does not need to reunify the codes when in switching contents, reduces the requirement of the analog live broadcasting service on the mobile equipment and the streaming media server, and shortens the required time for switching.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a mobile streaming media simulated live broadcast method and a content switching method used therein. Background technique [0002] With the construction of the third-generation mobile communication network, mobile streaming media services are increasingly valued and welcomed by telecom operators and users. At present, in addition to the basic streaming media business forms such as on-demand, live broadcast, and downloading, the analog live broadcast service composed of media files and / or live channels has also become an important business form, and is often used to carry out virtual live channels, or in the program Advertisement insertion during broadcasting, etc., the simulated live broadcast business increases the richness of the program and realizes the advertising operation that obtains revenue. [0003] Methods for realizing simulated live broadcasting can generally be ...
