Abstract
An encoding system (110) receives a report from a decoding system (120). The report identifies a packet comprising a first video portion of a video stream and comprises feedback indicating whether the first video portion was successfully received by the decoding system (120). The encoding system (110) configures a video encoder (115) to encode a second video portion of the video stream based on whether the feedback indicates that the first video portion was successfully received. Correspondingly, the decoding system (120) sends the report and decodes the second video portion in accordance with the encoding.

1-15. (canceled)
A method, implemented by an encoding system, the method comprising:
- receiving a report from a decoding system, wherein the report:
- identifies a packet comprising a first video portion of a video stream;
- and
- comprises feedback indicating whether the first video portion was successfully received by the decoding system;
- and
- responsive to determining that the feedback indicates that the first video portion was successfully received, configuring a video encoder in the encoding system to encode a second video portion of the video stream using a video frame comprising the first video portion as a reference frame.
An encoding system comprising:
- interface circuitry and processing circuitry communicatively connected to the interface circuitry, wherein the processing circuitry is configured to:
- receive a report from a decoding system via the interface circuitry, wherein the report:
- identifies a packet comprising a first video portion of a video stream;
- and
- comprises feedback indicating whether the first video portion was successfully received by the decoding system;
- and
- responsive to determining that the feedback indicates that the first video portion was successfully received, configure a video encoder in the encoding system to encode a second video portion of the video stream using a video frame comprising the first video portion as a reference frame.
A non-transitory computer readable medium storing software instructions that, when run on processing circuitry of an encoding system, cause the encoding system to:
- receive a report from a decoding system, wherein the report:
- identifies a packet comprising a first video portion of a video stream;
- and
- comprises feedback indicating whether the first video portion was successfully received by the decoding system;
- and
- responsive to determining that the feedback indicates that the first video portion was successfully received, configure a video encoder in the encoding system to encode a second video portion of the video stream using a video frame comprising the first video portion as a reference frame.
