Embodiment Construction

[0019] The content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] The general principle of the method described in the present invention: the user terminal sends the actual location of the user's random location to the download server by means of CGI (Common Gateway Interface, public gateway interface) parameters; the download server first searches in the live quasi-real-time streaming file, Find a video key frame (I-Frame) closest to the user's playback position; then the download server reconstructs the relevant media data after the key frame into a structure conforming to the standard file format and sends the data stream to the user terminal with the relevant protocol , the follow-up data will continue to be sent to the user terminal according to the method of live quasi-real-time streaming.

[0021] Such as figure 1 As shown in FIG. 2 , it is a schematic diagram of a random posit...

Abstract

The invention discloses a random positioning method in mobile streaming medium live-broadcast quasi real-time streaming service, which is applied to a mobile streaming medium service system which consists of a user terminal and a download server and comprises the steps as follows: (1) the user terminal receives the practical position information of the user random positioning and sends the information to the download server; (2) the download server searches in the live-broadcast quasi real-time streaming file according to the practical position information and finds out a video key frame which is closest to the practical position information of the user random positioning; (3) the download server re-constructs correlative streaming medium data after the key frame into a structure meeting the standard file format and sends the data stream to the user terminal to be read; the method solves the problem that in the mobile streaming medium service, the random positioning function can be provided for the user when the quasi real-time streaming service is in live broadcast.

Description

technical field [0001] The invention relates to the field of mobile streaming media, in particular to a random positioning method in the live quasi real-time streaming service of mobile streaming media. Background technique [0002] With the construction of 3G network, the mobile streaming media service is more and more valued and welcomed by telecom operators and users. However, telecom operators have found in the development of quasi-real-time streaming services of mobile streaming media that users often want to be able to randomly drag the current location of the live program being played in order to review some exciting scenes or quickly skip some content and return to the latest one. Live location to watch. [0003] If the random positioning function cannot be provided, the user experience satisfaction will be reduced. [0004] If the user is provided with a random positioning function, because the actual position that the user may drag is uncertain and ever-changing,...
