Abstract
A channel changing method and an apparatus thereof, where the method includes: sending, by a playback device to a fast channel change (FCC) server, a channel change request for a change to a target channel; receiving a low bit rate media stream of the target channel that is quickly sent by the FCC server, for playing; receiving, by the playback device, a source bit rate media stream of the target channel from a head end device when receiving a quick-sending end notification sent by the FCC server; and splicing, by the playback device, the source bit rate media stream of the target channel and the low bit rate media stream of the target channel and performing playing.
Claims20
A channel changing method implemented by a playback device to a fast channel change (FCC) server, the channel changing method comprising:
- sending a channel change request for a change to a target channel;
- receiving, a low bit rate media stream of the target channel from the FCC server;
- receiving a source bit rate media stream of the target channel from a head end device when receiving a quick-sending end notification from the FCC server;
- splicing the source bit rate media stream and the low bit rate media stream to create a spliced target media stream;
- and
- playing the spliced target media stream.
A channel changing method implemented by a fast channel change (FCC) server, the channel changing comprising:
- receiving a channel change request for a change to a target channel from a playback device;
- sending a low bit rate media stream of the target channel to the playback device at a preset high rate;
- receiving a source bit rate media stream of the target channel from a head end device;
- splicing the source bit rate media stream and the low bit rate media stream to create a spliced target media stream;
- sending the spliced target media stream to the playback device at the preset high rate;
- sending a quick-sending end notification to the playback device;
- and
- sending the target media stream to the playback device at a preset normal rate,
- wherein the quick-sending end notification instructs the playback device to receive the source bit rate media stream from the head end device, and
- wherein the preset high rate is higher than the preset normal rate.
A playback device comprising:
- a processor configured to splice a source bit rate media stream of a target channel and a low bit rate media stream of the target channel and perform playing;
- and
- a transceiver configured to:
- send, to a fast channel change (FCC) server, a channel change request for a change to the target channel;
- receive the low bit rate media stream of the target channel from the FCC server;
- and
- receive the source bit rate media stream from a head end device when receiving a quick-sending end notification from the FCC server.
