Abstract
Various methods, systems, and apparatuses can be used to adjust the group of pictures size for an encoder during encoding operations. In some implementations, group of pictures size can be reduced during periods of higher likelihood of channel change, and increased during periods of lower likelihood of channel change. Such adjustment can facilitate faster display of pictures after a channel change due to anchor frames being more quickly received.
Claims18
A computer-implemented method, comprising:
- identifying one or more periods within a program stream when there exists an increased potential for subscribers to request to join the program stream;
- during the one or more identified periods, reducing a size associated with a group of pictures within the program stream;
- and
- during periods outside of the one or more identified periods, increasing the size of the group of pictures within the program stream.
One or more non-transitory computer readable media operable to be executed by a processor, the one or more non-transitory computer readable media upon execution by the processor being operable to cause the processor to:
- identify one or more periods within a program stream when there exists an increased potential for subscribers to request to join the program stream;
- and
- vary a size associated with a group of pictures encoding within the program stream as a function of the one or more identified periods of increased potential for subscribers to request to join the program stream.
