Patent ID: 7587737

Claim:
A system comprising: a selector configured to select a lead-in video stream, where the lead-in stream corresponds to a particular main video-stream transmission; a receiver configured to receive the selected lead-in video-stream transmission; a presentation device configured to present content of the selected lead-in video stream transmission; a switcher configured to switch reception from the lead-in to the main video-stream transmission and to switch presentation from the content of the lead-in to the content of the main video-stream transmission; an inquisitor configured to query a video-stream provider asking the provider to identify which one of multiple lead-in video-stream transmissions is the first transmission with an available access point, wherein the identified lead-in transmission is the one selected, wherein a first one of the multiple lead-in video-stream transmissions includes data for a first number of frames, a second one of the multiple lead-in video-stream transmissions includes data for a second number of frames, the first number of frames being different from the second number of frames, the first number of frames being determined at least in part based on a first time and a next main video-stream access point transmission time, the first time being associated with a first beginning transmission time for the first one of the multiple lead-in video-stream transmissions, the second number of frames being determined at least in part based on a second time and the next main video-stream access point transmission time, the second time being associated with a second beginning transmission time for the second one of the multiple lead-in video-stream transmissions.
