Problems solved by technology

Among them, in order to improve the audio and video compression rate, the I frames in the general media data are relatively sparse, and the interval between the I frames will generally exceed 1s, or even exceed 2s, resulting in the most time-consuming waiting to receive the I frame of the new channel media data, which in turn leads to grouping. The switching speed of live channel in broadcast mode is relatively slow

Abstract

According to the intelligent set top box and the live channel switching method provided by the invention, in response to a channel switching instruction, a response request carrying cache parameters is sent to a unicast code stream server so as to trigger the unicast code stream server to send unicast streaming media data to a cache region; according to the invention, the cache parameter and the fast sending rate of the unicast code stream server are adjusted, and then the RTP packet corresponding to the first multicast streaming media data is continuously sent to the RTP packet corresponding to the unicast streaming media data in the cache region based on the RTP packet corresponding to the first multicast streaming media data; or splicing the multicast streaming media data and the unicast streaming media data based on the last RTP packet of the unicast streaming media data continuously to the RTP packet corresponding to the received multicast streaming media data; according to the method and the device, successful splicing of the multicast streaming media data and the unicast streaming media data can be ensured, and a section of unicast streaming media data starting from the I frame is cached in advance, so that the time for waiting for the I frame during channel switching in a multicast mode is saved, the live broadcast channel switching speed in the multicast mode is improved, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular, to an intelligent set-top box and a method for switching live channels. Background technique [0002] A set-top box, also known as a digital video converter box, is a device that connects a TV to an external signal source; it converts compressed digital signals into TV content and displays it on the TV. The signal of the set-top box can come from cable, satellite dish, broadband network and terrestrial broadcast. [0003] IPTV network set-top box live channels can be transmitted in unicast mode or multicast mode; in order to save network bandwidth, multicast mode is usually used for transmission, that is, the broadcast address of the live channel is the multicast address, and the media data is transmitted through the multicast mode. transmitted to the set-top box. The steps of switching the live channel in the multicast mode are: exit the multicast gro...
