Abstract:
1. A method for facilitating transitions between video streams, the method comprising: receiving a primary video stream that comprises a first primary video stream portion and a second primary video stream portion, wherein the second stream portion follows the first video stream portion; receiving a secondary video stream; processing at least one of the primary video stream and the secondary video stream to facilitate a seamless transition, at a multiple tuner device, between the first primary video stream portion and the secondary video stream; transmitting the primary video stream to a first tuner of the multiple tuner device over a first physical channel; transmitting the secondary video stream to a second tuner of the multiple tuner device over a second physical channel that differs from the first physical channel; wherein the primary video stream and secondary video stream are a same version of a same program; instructing the multiple tuner device to perform a seamless transition between the first primary video stream portion to the secondary video stream; wherein the processing comprises marking a first packet of a video frame of the primary video stream as a first synchronization point if the video frame has a same program clock reference (PCR) value and a same presentation time stamp (PTS) value as a frame of the secondary video stream.
