1. 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;
a 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.

9. A system comprising:
-
a selector configured to choose a particular main video-stream transmission for reception and presentation;
a receiver configured to temporarily receive, before the transmission of the next access point transmitted in the main video-stream transmission, a lead-in video stream that corresponds to the particular main video-stream transmission;
a switcher configured to switch reception from the lead-in to the main video-stream transmission;
wherein the lead-in video-stream transmission is scheduled for transmission during transmission of one group-of-pictures (GOP) of the main video-stream 11 transmission, wherein a GOP has only one access point. - View Dependent Claims (8, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
