Abstract: Entropy coding, such as multi-symbol arithmetic coding, is used in video compression to encode data into a compressed bit stream for transmission. Some entropy coding techniques are adaptive, meaning that the probability distribution is updated on the fly, based on the data. Accuracy of cumulative probability estimation in adaptive multi-symbol arithmetic coding can impact coding efficiency. To address the issue, a mixture of two or more adaptive cumulative probability estimations computed using two or more adaptation parameters can be used in place of a single cumulative probability estimate. The two or more adaptation parameters can be unique for a context model. A divergence in the adaptive cumulative probability estimations may signal a sudden change in the probability of a symbol. The divergence may trigger a reset of one or more adaptive cumulative probability estimations.

Abstract: A multi-adapter encoding process where the first adapter is used to execute a look-ahead encoding process while the second adapter is used to execute a main encoding process is provided. The look-ahead encode and main encode can be executed concurrently on the different adapters. Additionally, the first adapter can execute the look-ahead encoding process without feedback from the second adapter, or the main encoding process.

Abstract: Techniques related to scheduling and load balancing media tasks across heterogeneous hardware units are discussed. Such techniques include estimating completion times of received media tasks and, after submission of the media task to a selected hardware, only checking status of the media task after the estimated completion time.

Abstract: Described herein are video streaming techniques for applications and workloads executed in the cloud. In one example, the cloud server device encodes display frames using low-delay encoding techniques for transmission to a client device. The cloud server device receives an overlay bitstream from a client device, combines the overlay data with the display frames, and encodes the frames for the viewers using statistics from the display frames encoded for the client device and/or from the overlay data. The cloud server device can then transmit the bitstream to a third device for viewing (e.g., to a viewer device or a streaming server device).

Abstract: An apparatus to facilitate video streaming for cloud gaming is disclosed. The apparatus includes a processor to receive a first compressed content bitstream from a first server device; capture input content to utilize as overlay content for the first compressed content bitstream; determine whether one of a first mode of pass-through encoding is enabled or a second mode of look-ahead encoding is enabled; and responsive to the first mode of pass-through encoding being enabled: generate a second content bitstream representing the input content; multiplex the first compressed content bitstream with the second content bitstream to generate a third combined content bitstream; and transmit the third combined content bitstream to a streaming server device for streaming to one or more users.

Abstract: Techniques are provided for multi-channel video encoding with cross-channel look ahead rate control. A methodology implementing the techniques according to an embodiment includes encoding a first video channel to generate a first output bitstream and first channel statistics including a quantization parameter, the first video channel comprising a first plurality of video frames at a first resolution. The method further includes encoding a second video channel to generate a second output bitstream encoded at a bit rate based on the first channel statistics, the second video channel comprising a second plurality of video frames at a second resolution. The second resolution may equal the first resolution depending on target bit rates for the channels. The method further includes performing look ahead processing on the first video channel to generate first channel look ahead statistics, and encoding the second video channel based on the first channel look ahead statistics.
