Systems and methods for error detection in transmitted video data

An encoding computing system, comprising:

• one or more processors;
• and
• one or more tangible, non-transitory, computer readable media that collectively store instructions that when executed by the one or more processors cause the encoding computing system to perform operations, the operations comprising:
• receiving a video frame from a video frame capture device;
• encoding the video frame according to an encoding scheme to produce an encoded video frame;
• decoding the encoded video frame according to a decoding scheme corresponding to the encoding scheme to obtain a decoded video frame;
• applying an error detection code generation scheme to the decoded video frame to generate a frame error detection code;
• sending the encoded video frame and the frame error detection code to a decoding computing system;
• receiving a replacement frame request from the decoding computing system;
• in response to the replacement frame request:
• generating a replacement encoded video frame by encoding the video frame according to the encoding scheme to produce the replacement encoded video frame;
• and
• sending the replacement encoded video frame to the decoding computing system.

One or more tangible, non-transitory computer readable media storing computer-readable instructions that when executed by one or more processors cause the one or more processors to perform operations, the operations comprising:

• receiving a video frame from a video frame capture device;
• encoding the video frame according to an encoding scheme to produce a first encoded video frame;
• decoding the first encoded video frame according to a decoding scheme corresponding to the encoding scheme to obtain a first decoded video frame;
• applying an error detection code generation scheme to the first decoded video frame to generate a first frame error detection code;
• decoding the encoded video frame according to the decoding scheme corresponding to the encoding scheme to obtain a second decoded video frame;
• applying the error detection code generation scheme to the second decoded video frame to generate a second frame error detection code;
• determining error data describing one or more differences between the first frame error detection code and the second frame error detection code;
• determining, based on the error data exceeding one or more error thresholds, that the encoded video frame is a corrupted video frame;
• and
• in response to the determination that the encoded video frame is a corrupted video frame, sending a replacement frame request to the video frame capture device, wherein the replacement frame request requests a replacement encoded video frame for the encoded video frame.
