Abstract
Techniques for improved rendition switching in association with adaptive bitrate streaming are described herein. The disclosed techniques may allow switching between segments at P-frames in addition to IDR-frames. By allowing switching at P-frames, the disclosed techniques may improve efficiency by, for example, reducing end-to-end latency without causing an undesirable decrease in image quality and image fidelity. In some examples, switching to a lower image quality rendition (e.g., lower bitrate, lower resolution, etc.) may be accomplished using P-frame switching, IDR-frame switching or both. Also, in some examples, switching to a higher image quality rendition (e.g., higher bitrate, higher resolution, etc.) may be accomplished using only IDR-frame switching.
