Abstract

Disclosed in the invention is an automatic repeat request (ARQ) controlling method of multi-media data. The ARQ controlling method comprises the following steps: obtaining a lost multi-media data packet, priority information of the lost multi-media data packet, and a current network condition; and employing a corresponding re-transmission strategy to re-transmit the lost multi-media data packet. In addition, the invention also discloses an ARQ controlling system for the multi-media data. A problem that correct decoding relying on a multi-media data packet with the high priority level can not be carried out due to abandoning of the multi-media data packet with the high priority level when ARQ controlling is carried out can be solved.

Description

technical field

[0001] The present invention relates to the technical field of streaming media, in particular to an ARQ control method and system for multimedia data. Background technique

[0002] With the popularization of broadband network and the development of multimedia technology, the application of streaming media technology is becoming more and more extensive, such as digital broadcasting services, IPTV services, mobile streaming media services and so on. The common feature of these services is that after the multimedia data is packaged and packaged according to certain rules, the data is distributed through the underlying communication network. For example, in an IPTV application, TS over RTP (Real-time Transport Protocol, Real-time Transport Protocol) or TS over UDP (User Datagram Protocol, User Datagram Protocol) are used to distribute through the IP network. In the field of digital broadcasting, TS (Transport Stream, Transport Stream) is directly used as a trans...
