Problems solved by technology

[0007] 1. The load of the retransmission server increases instantaneously, which may lead to abnormal working status or failure to respond to retransmission requests of some terminals in time;
[0008] 2. Retransmitting data packets to multiple users at the same time will lead to a sharp increase in the occupied network bandwidth, making it difficult to plan network bandwidth, and may lead to further network congestion, which will further aggravate packet loss and the entire system will be in an unstable state

Abstract

The embodiment of the invention provides a method for ensuring service quality of live broadcast of a web television. The method includes the steps as follows: detecting a live broadcasting message received from an original multicast group; adding a multicast group corresponding to a delay multicast flow sent by a re-transmission server and receiving a delay re-sending message from the delay multicast flow; and recovering the live broadcasting message according to the received delay re-sending message. Correspondingly, the invention also provides a terminal and the re-transmission server. Theterminal can directly receive a message to recover in the delay message flow sent from the re-transmission server once detecting that an original message is lost or false, and does not need to send Nack information to the re-transmission server for requesting the re-transmission of data, therefore, Nack storm is avoided, the processing of the re-transmission server is simplified and the efficiency of the re-transmission is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and equipment for guaranteeing service quality of network television live broadcast services. Background technique [0002] In recent years, the Internet Protocol Television (IPTV) service, which uses set-top boxes and TV sets as terminals, uses broadband IP as the transmission technology, focuses on audio-visual services, and integrates instant messaging, games, and information services, has attracted the attention of operators in recent years. Attention, since the second half of 2004, domestic operators have accelerated the pace of IPTV pilot construction. As an emerging service provision method, IPTV provides opportunities for potential new business, new income, and new business model, and will bring new profit growth points for communication and media service providers. [0003] As the basic service of IPTV, the live broadcast service is the inheritance of th...
