Abstract

A system for providing video playback includes an interface and a processor. The interface is configured to receive a desired video playback request and receive a video content source switching request from a first video content source to a second video content source. The processor is configured to generate a not-all-I-frame first stream for the first video content source, generate an all-I-frame second stream and a not-all-I-frame second stream for the second video content source, switch from the not-all-I-frame first stream for the first video content source to the all-I-frame second stream for the second video content source, and switch from the all-I-frame second stream for the second video content source to the not-all-I-frame second stream for the second video content source on a next I-frame occurrence in the not-all-I-frame second stream for the second video content source.

Dependent claims

A system for providing video playback, comprising:

an interface configured to:
receive a desired video playback request;
receive a first video content source switching request from a first video content source to a second video content source;
receive a second video content source switching request from the second video content source to a third video content source;
and
a processor configured to:
provide a not-all-I-frame first stream for the first video content source;
generate an all-I-frame second stream and a not-all-I-frame second stream for the second video content source;
generate an all-I-frame third stream and a not-all-I-frame third stream for the third video content source;
in response to receiving the first video content source switching request, switch from providing the not-all-I-frame first stream for the first video content source to providing the all-I-frame second stream for the second video content source;
determine whether the second video content source switching request is received when an immediate switch is not possible to a next I-frame occurrence in the not-all-I-frame third stream;
and
in response to a determination that the second video content source switching request is received when an immediate switch is not possible to the next I-frame occurrence in the not-all-I-frame third stream, switch from providing the all-I-frame second stream for the second video content source to providing the all-I-frame third stream video content source;
and
in response to a determination that the second video content source switching request is received when an immediate switch is not possible to the next I-frame occurrence in the not-all-I-frame third stream, switch from providing the not-all-I-frame second stream for the second video content source to providing the all-I-frame third stream video content source.
