Abstract: Activation scaled clipping layers for neural networks are described. An activation scaled clipping layer processes an output of a neuron in a neural network using a scaling parameter and a clipping parameter. The scaling parameter defines how numerical values are amplified relative to zero. The clipping parameter specifies a numerical threshold that causes the neuron output to be expressed as a value defined by the numerical threshold if the neuron output satisfies the numerical threshold. In some implementations, the scaling parameter is linear and treats numbers within a numerical range as being equivalent, such that any number in the range is scaled by a defined magnitude, regardless of value. Alternatively, the scaling parameter is nonlinear, which causes the activation scaled clipping layer to amplify numbers within a range by different magnitudes. Each scaling and clipping parameter is learnable during training of a machine learning model implementing the neural network.

Abstract: Systems, apparatuses, and methods for performing efficient video transmission are disclosed. In a video processing system, a transmitter identifies multiple planes in a scene. The transmitter renders and compresses each of the multiple planes with a combination of a corresponding compression level and a resolution, which is different from a combination of compression level and resolution of any other plane. For each plane, the transmitter inserts, in multi-plane information, data such as identification of the plane, a location in the video frame for the plane, and one or more of a resolution and compression level for the plane. The transmitter conveys the rendered and compressed planes along with the multi-plane information to a receiver. The receiver decodes each of the planes and insets each of the planes on any lower resolution planes of the multiple planes.

Abstract: Systems, apparatuses, and methods for performing efficient video compression are disclosed. A video processing system includes a transmitter sending a video stream over a wireless link to a receiver. The transmitter includes a processor and an encoder. The processor generates rendered blocks of pixels of a video frame, and when the processor predicts a compression level for a given region of the video frame is different from a compression level for immediately neighboring blocks, the processor generates side information. The side information identifies a location of the given region in the video frame and a type of content that causes the compression level differences. The processor sends the rendered video information and the side information as accompanying metadata to the encoder. The encoder updates encoding parameters based on the received side information, and compresses the rendered given region based on the updated encoding parameters.

Abstract: Systems, apparatuses, and methods for performing efficient bitrate control of video compression are disclosed. Logic in a bitrate controller of a video encoder receives a target block bitstream length for a block of pixels of a video frame. When the logic determines a count of previously compressed blocks does not exceed a count threshold, the logic selects a quantization parameter from a full range of available quantization parameters. After encoding the block, the logic determines a parameter based on a first ratio of the achieved block bitstream length to an exponential value of an actual quantization parameter used to generate the achieved block bitstream length. For another block, when the count exceeds the count threshold, the logic generates a quantization parameter based on a ratio of the target block bitstream length to an average of parameters of previously encoded blocks.
