Abstract: Systems, apparatuses, and methods for utilizing different modulation coding schemes (MCSs) for different components of a video stream are disclosed. A system includes a transmitter sending a video stream over a wireless link to a receiver. The transmitter splits the video stream into low, medium, and high quality components, and then the transmitter modulates the different components using different MCS's. For example, the transmitter modulates the low quality component using a lower, robust MCS level to increase the likelihood that this component is received. Also, the medium quality component is modulated using a medium MCS level and the high frequency component is modulated using a higher MCS level. If only the low quality component is received by the receiver, then the receiver reconstructs and displays a low quality video frame from this component, which avoids a glitch in the display of the video stream.

Abstract: Systems, apparatuses, and methods for implementing real-time, low-latency packetization protocols for live compressed video data are disclosed. A wireless transmitter includes at least a codec and a media access control (MAC) layer unit. In order for the codec to communicate with the MAC layer unit, the codec encodes the compression ratio in a header embedded inside the encoded video stream. The MAC layer unit extracts the compression ratio from the header and determines a modulation coding scheme (MCS) for transferring the video stream based on the compression ratio. The MAC layer unit and the codec also implement a feedback loop such that the MAC layer unit can command the codec to adjust the compression ratio. Since the changes to the video might not be implemented immediately, the MAC layer unit relies on the header to determine when the video data is coming in with the requested compression ratio.

Abstract: Systems, apparatuses, and methods for implementing stereoscopic interleaved compression techniques are disclosed. A system includes a transmitter sending a video stream over a wireless link to a receiver. For each pair of frames, the transmitter encodes a left-half of a first frame of the pair with an amount of compression less than a first threshold and encodes a right-half of the first frame with an amount of compression greater than a second threshold. For a second frame of the pair, the transmitter encodes a right-half of the second frame with an amount of compression less than the first threshold and encodes a left-half of the second frame with an amount of compression greater than the second threshold. The transmitter conveys encoded half-frames and indications of an amount of compression used for each half-frame to a receiver. The receiver receives, decodes, and drives the encoded half-frames to a display.
