  • Publication number: 20240111596
    Abstract: A scheduler of an apparatus exposes an application programming interface (API) usable to specify quality-of-service (QoS) parameters, e.g., latency, throughput, and so forth. An application, for instance, specifies the QoS parameters for a workload to be processed using a hardware compute unit. The QoS parameters are employed by the scheduler as a basis to configure a partition within a hardware compute unit. The partition is configured such that processing resources that are available via the partition to process the workload comply with the specified quality-of-service.

  • Patent number: 11816871
    Abstract: Methods and devices are provided for processing image data on a sub-frame portion basis using layers of a convolutional neural network. The processing device comprises memory and a processor. The processor is configured to receive frames of image data comprising sub-frame portions, schedule a first sub-frame portion of a first frame to be processed by a first layer of the convolutional neural network when the first sub-frame portion is available for processing, process the first sub-frame portion by the first layer and continue the processing of the first sub-frame portion by the first layer when it is determined that there is sufficient image data available for the first layer to continue processing of the first sub-frame portion. Processing on a sub-frame portion basis continues for subsequent layers such that processing by a layer can begin as soon as sufficient data is available for the layer.

  • Patent number: 9167285
    Abstract: A streaming video server generates a virtual file system that includes virtual addresses of a plurality of encrypted segments of a plurality of video programs at each of a plurality of bitrates, without storing the plurality of encrypted segments in persistent storage. A request is received from a client device to access a selected one of the plurality of video programs via a request to access the virtual file system. The plurality of encrypted segments of the selected one of the plurality of video programs are generated at a selected bitrate, in response to the request.

  • Patent number: 9124672
    Abstract: A streaming video server includes a virtual file system that stores playlist data corresponding to a plurality of video programs available from at least one video source and that stores variant playlist data corresponding to each of the plurality of video programs that indicates a single variant for streaming each of the plurality of video programs. The streaming video server receives a request for a selected one of the plurality of video programs from a client device. The selected one of the plurality of video programs is retrieved from the at least one video source in response to the request. A rate generator generates rate data based on the transmission feedback data. A plurality of encoded segments are generated from the selected one of the plurality of video programs, based on rate data.

  • Patent number: 9015470
    Abstract: A streaming video server includes a virtual file system that stores playlist data corresponding to a plurality of video programs available from at least one video source and that stores at least one initial video program segment for each of the plurality of video segments. The streaming video server receives a request for a selected one of the plurality of video programs from a client device. The selected one of the plurality of video programs is retrieved from the at least one video source in response to the request. A plurality of encoded segments are generated from the selected one of the plurality of video programs, based on rate data. A multiplexer generates a plurality of output segments from the at least one initial video program segment corresponding to the selected one of the plurality of video programs and the plurality of encoded video program segments.

  • Publication number: 20140331262
    Abstract: A streaming video server includes a virtual file system that receives a request for a selected one of the plurality of video programs from a client device. The selected one of the plurality of video program is retrieved from the at least one video source in response to the request. A plurality of encoded segments are generated from the selected one of the plurality of video programs, based on at least one encoding parameter that is adjusted in response to context data relating to the streaming session for the selected one of the plurality of video programs.
