Reducing channel change delays |
摘要 |
Technology which facilitates a reduction in time of the presentation of video content after a viewer changes channels is described. Frames of a video stream associated with a channel are analyzed to identify locations of access points in the video stream prior to relaying the video stream to a presentation device. Information indicating the locations of access points is stored. The video stream is then time shifted on a continuous basis and is transmitted to the presentation device which made the request for as long as the presentation device remains tuned to the channel corresponding to the request. A first available frame on or before an access point of the time shifted video stream is selected based on the stored information, which is used to commence the transmission of the time shifted video to the presentation device, which facilitates a more immediate presentation of video content.
