Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict.

[0025] Considering the diversity of terminal operating systems, and in order to improve the application range of media streams, embodiments of the present invention provide a method and device for reorganizing media data. A detailed description will be given below through examples.

[0026] See figure 2 As shown in the flowchart of the method for reorganizing media data, the method includes the following steps:

[0027] Step S202, demultiplexing the transport stream (ie TS stream) of the program to obtain the original media data of the program; wherein, the original media data includes: video data; in addition, the original media data also includes audio data and other data;

[0028] Step S20...

Abstract

The invention discloses a method and device for reconstructing media data. The method comprises the step of de-multiplexing a transport stream of a program to obtain original media data including video data of the program, the step of resetting a PCR in the original media data according to a local clock, the step of slicing the original media data with the reset PCR according to the method of regarding an I frame of the video data as an initial frame of the video data of slices, the step of setting index messages for all slices, and the step of regarding the slices on which the index messages are set as reconstructed data of the program to be stored. The method and device for reconstructing the media data solve the problem that due to the fact that the requirements for streaming media initial data formats of operating systems of different client terminals are different, streaming media cannot be played normally, and the performance of the service of directly playing the streaming media among the client terminals is promoted.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a method and device for reorganizing media data. Background technique [0002] In the MPEG (Moving Picture Experts Group) standard, the codec equipment has a basic time reference when processing TS (Transport Stream, also referred to as TS stream). This time reference is PCR (Program Clock Reference, program reference clock). Generally speaking, PCR is generated at the encoding end and needs to be accurately transmitted to the decoding end for decoding. PCR is very critical for the quality and mutual delay of video and audio. However, every time the TS stream is processed by the device during the transmission process, due to changes in the code rate and the relationship between the TS packets, it will have a relatively large impact on the jitter and interval of the PCR, thereby affecting the normal decoding of the terminal. [0003] In the process of transmission, streaming medi...
