Synchronization playing method based on video data block distribution

Abstract

The invention belongs to the digital video technology field, and is a video synchronization playing method specifically. According to the invention, a plurality of mobile terminus are connected to same local area network, wherein a mobile terminal is selected as a center node which stores video file in need of synchronization playing. The center node firstly divides the video file as video data blocks with same time length, and gives integer time stamp thus the video blocks are in progressive maximum according to a natural number sequence. Other terminus nodes are selected as normal nodes to connect the center node, obtains video data blocks distributed by the center node, and carries out synchronization video playing through the integer time stamp. Through sending time stamp updating information to the normal nodes, the center node controls play progress of the normal nodes. The invention relates to video data extraction, video data block distribution and video synchronization play. The method in the invention has high file transmission rate, and user experience pleasure is increased.

Description

technical field [0001] The invention belongs to the technical field of digital video, and in particular relates to video file format conversion, a video data block distribution strategy, and a video synchronous playing method. Background technique [0002] In recent years, the popularization of intelligent terminals such as smartphones and tablet computers has greatly enriched people's leisure and entertainment life. According to statistics from the Ministry of Industry and Information Technology, by the end of 2008, the number of mobile phone users in China had exceeded 640 million. In 2009, the Ministry of Industry and Information Technology issued 3G licenses to China Mobile, China Telecom and China Unicom, which marked my country's formal entry into the 3G era. The progress of communication technology and the improvement of terminal hardware level have injected a strong impetus into the development of mobile Internet, the content of network applications has been continu...

Problems solved by technology

The transmission rate of Bluetooth technology is very slow, and limited by the physical distance, it is not suitable for transmitting large video files; currently there is no mature mechanism to directly transmit files between mobile phones, tablet computers and other terminals through WiFi, even if a set similar to the traditional one is developed The server-client transmission system of the desktop computer still requires waiting time, and it is a bit of a fuss

[0008] (2) In the case of many users, it takes longer to transfer video files

[0009] (3) Even if the transmission of the video file is completed, multiple users still watch separately, and there will inevitably be a time difference in video playback

This is not conducive to the communication between users and reduces the fun; and playing videos separately in a small area can cause mutual interference of sounds, which greatly reduces the user experience
