Embodiment Construction

[0098] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0099] The idea of ​​the present invention is to first establish a first correspondence between the first time information of the first media stream data packet and the first display time; establish a second correspondence between the second time information of the second media stream data packet and the second display time ; According to the corresponding relationship, when the difference between the first display time and the second display time corresponding to the time information is less than a threshold, display the first media stream data packet and the second media stream data packet simultaneously. The essence of the concept of the present invention is that by using the time information inherent in each data packet in each media stream to establish a corresponding relationship, and because different media streams need to be synchronized, ...

Abstract

The invention discloses a synchrony method and a synchro system between different media streams. The invention includes the following steps: the first corresponding relationship between the first time information and the first display time of a first media stream data packet is established; the second corresponding relationship between the second time information and the second display time of a second media stream data packet is established; according to the corresponding relationship, the first media stream media stream data packet and the second media stream data packet are displayed simultaneously when a difference value between the first display time and the second display time is less than a threshold value. The invention realizes the synchrony of different media streams from a broadcast network program or from a broadband program, and solves a synchrony of media streams from different networks, and possesses a remarkable actual application effect and significance in the modern media stream technology.

Description

technical field [0001] The invention relates to a synchronization technology of data streams among media streams, in particular to a synchronization technology of data streams between different media streams. Background technique [0002] There are various media streams in modern communication, among which transport stream and real-time transport protocol stream are more representative. [0003] 1. Synchronization of Transport Stream (TS, Transport Stream). [0004] The Moving Picture Experts Group (MPEG, Moving Picture Exports Group) was established in 1988. MPEG-2 is one of the international standards (moving image and sound coding) promulgated by it. It was formulated in 1994 and is designed for advanced industry standard image quality and higher transmission rate. The coding rate ranges from 3 megabits to 100 megabits per second, which is a broadcast-quality image compression standard and has CD-level sound quality. It is one of the core technologies in various fields...
