Abstract

Provided are a data processing method and device, the method comprising: after a first terminal device receives a play request message that a user requests to play a first channel, an identifier of asecond terminal device that plays the first channel in a sub-network can be obtained from a gateway, and then the first terminal device, according to the identifier of the second terminal device, andobtains a first multicast data stream of the first channel cached by the second terminal device from the second terminal device, and the first multicast data stream of the first channel is pushed to aplaying device. Since a first data frame of the first multicast data stream is the key frame, the first terminal device can directly decode the multicast data stream and push the multicast data stream to the playing device for playing, and does not need to spend time in waiting for the arrival of the key frame. Therefore, according to the embodiment of the invention, on the basis that the EPG does not need to be modified and excessive FCC servers do not need to be erected, a quick channel changing function can be realized.

Description

technical field [0001] The invention relates to data processing technology, in particular to a data processing method and equipment. Background technique [0002] Internet Protocol Television (Internet Protocol Television, referred to as: IPTV) is an interactive Internet TV, which uses a broadband network and integrates Internet, multimedia, communication and other technologies to provide home users with a variety of interactive services including digital TV. A new technology for service. Currently, an IPTV system includes a multicast server, multiple gateways, and multiple set-top boxes (Set Top Box, STB for short). Wherein, the multicast server provides the multicast data stream of the live program to the STBs joining the multicast group in a multicast manner. The STB is connected to a playback device (such as a TV) on the user side, and is used to push the multicast data stream of the live program received from the multicast server to the playback device for playback. ...
