SYSTEM AND METHOD OF PROVIDING VIDEO CONTENT

摘要

A system includes a processor and a memory. The memory stores instructions that, when executed by the processor, cause the processor to perform operations including sending a primary multicast video stream and a secondary multicast video stream to a media device. The secondary multicast video stream is limited to intra-coded frames (I-frames) extracted from the primary multicast video stream. Transmission of each intra-coded frame (I-frame) of the secondary multicast video stream is delayed with respect to transmission of a corresponding I-frame of the primary multicast video stream. The delay is based on an amount of writing time to satisfy a buffer threshold of a video content buffer at the media device to prevent a noticeable time shift of video displayed by the media device when the media device switches from outputting the secondary multicast video stream to outputting the primary multicast video stream.

1. A server comprising:
a processor; and a memory storing instructions that, when executed by the processor, cause the processor to perform operations comprising:
sending a primary multicast video stream corresponding to a particular channel to a media device; andsending a secondary multicast video stream to the media device, wherein the secondary multicast video stream is limited to a plurality of intra-coded frames (I-frames) extracted from the primary multicast video stream, wherein transmission of each intra-coded frame (I-frame) of the secondary multicast video stream is delayed with respect to transmission of a corresponding I-frame of the primary multicast video stream, and wherein the delay is based on an amount of writing time to satisfy a buffer threshold of a video content buffer at the media device to prevent a noticeable time shift of video displayed by the media device when the media device switches from outputting the secondary multicast video stream to outputting the primary multicast video stream.
