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 by streaming at least an additional stream parallel with the main multicast stream. The alternative parallel stream having offset start points from the main multicast stream to more quickly provide a picture in response to a tuning command.
