Method and apparatus for providing information in video transitions
First Claim
1. An apparatus, comprising:
- means for providing an output to a display in response to an input signal received from a video source, said output providing means including means for buffering the input signal;
means for decoding an encoded video signal into a decoded video signal; and
means, coupled to said output providing means, for overlaying the decoded video signal decoded by said decoding means onto the display during a transition when said output providing means switches from a first video source to a second video source, wherein said apparatus comprises a plurality of encoded video signals, said apparatus being capable of selecting a specific encoded video signal for decoding and display during the transition based upon said encoded video signal'"'"'s relevance to either a content'"'"'s subject matter displayed by the first video source prior to the transition or a content'"'"'s subject matter selected for display via the second video source following the transition.

Abstract
A video system displays information during transition from a first video source to a second video source. During the transition, an MPEG decoder decodes a transition video signal and provides the decoded transition video signal to a video overlay which overlays the decoded transition video signal onto a display during the transition period. In one embodiment, the transition video may be a commercial video or advertisement such that the advertisement is displayed on the display during the transition. The advertisement may be related to the content of the output of one of the video sources. In the event the MPEG decoder is unavailable to decode the transition video during the transition, the video system is capable of utilizing an alternate decoder to decode the transition video.

14. An apparatus, comprising:
-
means for providing an output to a display in response to an input signal received from a video source, said output providing means including means for buffering the input signal;
means for decoding an encoded video signal into a decoded video signal; and
means, coupled to said output providing means, for overlaying the decoded video signal decoded by said decoding means onto the display during a transition when said output providing means switches from a first video source to a second video source, wherein said apparatus is capable of extending the transition to a predetermined time duration when said output providing means switches from the first video source to the second video source, thereby ensuring that the decoded video signal is capable of being displayed in its entirety. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

32. A method performed by a video system for providing information in video transitions, comprising:
-
selecting a video for transition;
receiving the transition video;
storing the transition video;
detecting an occurrence of a video transition from a first video source to a second video source;
if an occurrence of a video transition from a first video source to a second video source is detected, then determining if a first decoder is available; and
if the first decoder is not available, then selecting a second decoder. - View Dependent Claims (33, 34, 35, 36)
