1. A computer-readable medium having computer-executable instructions that, when executed by a computer, perform a method comprising:
- selecting a lead-in video stream, where the lead-in stream corresponds to a particular main video-stream transmission;
receiving the selected lead-in video-stream transmission;
presenting content of the selected lead-in video stream transmission;
switching reception from the lead-in to the main video-stream transmission;
switching presentation from the content of the lead-in to the content of the main video-stream transmission.

Abstract
Described herein is a technology facilitating the presentation of digital video streams. An implementation, described herein, reduces the effective start-up delay in the presentation of the first frames of the video content that occurs when a system tunes into a video stream. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.

9. A computer-readable medium having computer-executable instructions that, when executed by a computer, perform a method comprising:
-
choosing a particular main video-stream transmission for reception and presentation;
before the transmission of the next access point transmitted in the main video-stream transmission, temporarily receiving a lead-in video stream that corresponds to the particular main video-stream transmission;
switching reception from the lead-in to the main video-stream transmission. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A computer-readable medium having computer-executable instructions that, when executed by a computer, perform a method comprising:
-
preparing multiple video-streams based upon the same original video content for an overlapping transmission schedule so that the access point of each is phase-staggered;
transmitting one of more of the multiple video-streams over a communications network in accordance with the overlapping transmission schedule. - View Dependent Claims (19, 20)
