Reducing channel change delays
First Claim
1. A method for reducing channel change delays, comprising:
- receiving a channel change request;
transporting a video stream associated with the channel change request;
identifying at least one access point in the video stream;
time shifting the video stream resulting in a time shifted video stream;
transmitting the time shifted video stream to a presentation device on a continuous basis without returning to the video stream; and
selecting a frame of the time shifted video stream on or before the access point to commence the transmission of the time shifted video stream.

Abstract
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.

10. A computer-readable medium having computer-executable instructions that, when executed by a computer perform a method comprising:
- analyzing a video stream before the video stream is relayed to a presentation device;
identifying where at least one access point in the video stream is located; and
forwarding information indicating where the at least one access point is located based upon the identification. - View Dependent Claims (11, 12, 13, 14)

15. A system for reducing delay-associated with the initial presentation of video content after a channel change request, comprising:
-
means for analyzing frames of a video stream associated with a channel to identify locations of access points in the video stream prior to relaying the video stream to a presentation device; means for storing information indicating the locations of the access points; means for time shifting the video stream; means for transmitting the time shifted video stream to a presentation device on a continuous basis for so long as the presentation device remains tuned to the channel corresponding to the channel change request; and means for selecting the first available frame on or before an access point to commence transmission of the time shifted video stream to the presentation device, wherein the selection is based on the stored information. - View Dependent Claims (16, 17, 18, 19, 20)
