Embodiment Construction

[0031] In order to perform media playback control when the media control device and the media processing device have separate structures, embodiments of the present invention provide a media playback control method, system, and device.

[0032] When controlling the playback of the media stream, various operations may be required, such as normal speed playback, fast forward, fast rewind, slow forward, slow rewind, pause, resume, jump, stop, etc. Media streams may need to be converted to each other when they are in these operating states. The conversion relationship between various operating states is as follows: figure 1 Shown:

[0033] When the media stream is played at a normal rate, it can jump, and then continue to play at a normal rate, and can perform two-way mutual conversion with fast forward, fast rewind, slow forward, slow rewind, pause, stop, etc. Switching to normal speed playback is recovery; in fast forward, fast rewind, slow forward, slow rewind and other states...

Abstract

The invention discloses a media playing control method comprising: media control device receives operation request, analyze the operation request, sends request message of H.248 format to media processing apparatus according to the operation request; media processing equipment operates the media stream according to request message of H.248 format. The invention also discloses a media playing control system comprising media control equipment, for analyzing the operation request on receiving operation request, sending request message of H.248 format according to the operation request; a media processing equipment, for receiving request message of H.248 format, operating the media stream according to request message of H.248 format. The invention can perform media playing control fitting H.248 protocol when media control equipment and media processing equipment are separate structure.

Description

technical field [0001] The present invention relates to the technical field of media playing, in particular to a media playing control method and system. Background technique [0002] With the development of wireless communication technology, real-time multimedia services have also been widely used, among which streaming media services such as video on demand are especially welcomed by users. [0003] In the process of playing the media stream, it may be necessary to perform some playback controls on the media stream, for example: control operations such as play, pause, fast forward, fast rewind, resume, jump and stop. When performing streaming media services such as video on demand, users may need to control the on-demand media stream according to their own needs to achieve personalized services. For example, they can quickly browse media streams and jump directly to interested locations. Playback can be paused at any time, resumed at any time, etc. [0004] The Internati...
