  • Patent number: 10749918
    Abstract: Methods and systems for early identification of bitrates for segments in adaptive bitrate streaming can allow the server to begin processing or transcoding content as necessary for delivery, reducing processing and transmission latency. In a first aspect, a client may request a second segment before the first segment has been completely received. The server may begin any transcoding processes for preparing the second segment, and once the server has completed sending the first segment, the server may begin transmitting the now-prepared or partially prepared second segment. The server can then transmit the first and second segment contiguously, with essentially no network dead time. In a second aspect, the client may transmit an early notification of parameters for the request of the second segment, allowing the server to begin transcoding. The client may subsequently request the already-prepared or partially prepared second segment, similarly reducing request-response processing latency.

  • Patent number: 10742992
    Abstract: A video compression system and method may be used to compress video data using both resolution compression and texture compression. The compression may involve converting the video format from a first format to a second format and then performing resolution compression across blocks of pixels within each frame of the video. The resolution compressed data may then be arranged as data triplets spanning three consecutive frames of the video. The data triplets may be texture compressed using ETC or other texture compression techniques. The compressed video may be part of other applications, such as a video to be played within a video game. A client device may be able to decompress the compressed video by reversing the texture compression, reversing the resolution compression, and performing a format conversion to generate uncompressed video data that can be used to play the video.

  • Patent number: 10732293
    Abstract: A quadrature fully integrated tri-band GPS receiver implemented in 65 nm CMOS. The analog front-end (AFE) is specifically designed for a miniaturized low-power GPS logger that leverages heavy duty-cycling. The main contribution of the RF front-end is comprised of two main signal paths which support the single-band only mode and the tri-band mode (L1, L2, L5). In the tri-band mode, the AFE is able to fold three GPS signals into a single low intermediate frequency channel in part due to the orthogonality of the pseudo-ransom codes. In active mode, the radio draws 12.1 mW in the single-band (L1) mode with a LNA and an active mixer, and 8.2 mW in the tri-band mode with a passive front-end, from a 1.2 V supply, and with a startup time of 20 us.

    Abstract: A method and system for bit rate control during encoding of multimedia data are disclosed. A change in complexity of a multimedia picture relative to complexity associated with one or more multimedia pictures in a multimedia sequence is determined. A complexity associated with a multimedia picture is determined based on number of bits and an average quantization associated with the multimedia picture. A bit rate is adjusted for encoding the multimedia picture based on the change in complexity of the multimedia picture. The bit rate is increased on determining an increase in complexity of the multimedia picture and is decreased on determining a decrease in complexity of the multimedia picture. Utilization of additional bits during the increase in the bit rate and saving of bits during the decrease in the bit rate are compensated during adjusting of bit rates for encoding subsequent multimedia pictures in the multimedia sequence.

  • Patent number: 10715831
    Abstract: Methods and apparatus for stereoscopic image encoding and decoding are described. Left and right eye images are encoded following an entropy reduction operation being applied to one of the eye images when there is a difference between the left and right images of an image pair. Information about regions of negative parallax within the entropy reduced image of an image pair is encoded along with the images. Upon decoding a sharpening filter is applied to the image in an image pair which was subjected to the entropy reduction operation. In addition edge enhancement filtering is performed on the regions of the recovered entropy reduced image which are identified in the encoded image data as regions of negative parallax. Interleaving of left and right eye images at the input of the encoder combined with entropy reduction allows for efficient encoding, storage, and transmission of 3D images.

For data sets, such as DNN weights, where the elements are multi-bit values, bits of the same level of significance from the elements of the data set are formed into data streams. For example, the most significant bit from each of the data elements are formed into one data stream, the next most significant bit into a second data stream, and so on.

  • Patent number: 10630990
    Abstract: A video packaging and origination service can include one or more encoder components that receive content for encoding and transmitting to requesting entities. During the operation of the encoder components, individual encoders receive input signals for encoding and determine quality metric information related to the generation of an encoded segment. The encoder components exchange quality metric information and an encoder component is selected to transmit an encoded segment. The selection of an individual encoder component per segment can continue throughout the streaming process.

  • Patent number: 10623733
    Abstract: Several systems and methods for intra-prediction estimation of video pictures are disclosed. In an embodiment, the method includes accessing four ‘N×N’ pixel blocks comprising luma-related pixels. The four ‘N×N’ pixel blocks collectively configure a ‘2N×2N’ pixel block. A first pre-determined number of candidate luma intra-prediction modes is accessed for each of the four ‘N×N’ pixel blocks. A presence of one or more luma intra-prediction modes that are common among the candidate luma intra-prediction modes of at least two of the four ‘N×N’ pixel blocks is identified. The method further includes performing, based on the identification, one of (1) selecting a principal luma intra-prediction mode for the ‘2N×2N’ pixel block and (2) limiting a partitioning size to a ‘N×N’ pixel block size for a portion of the video picture corresponding to the ‘2N×2N’ pixel block.

  • Patent number: 10602147
    Abstract: A system and method of forming entropy coding groups in an entropy encoder operating in a transform mode includes receiving a block of a first number of quantized transform coefficients as a current block of sample values and evaluating the current block of sample values using one or more grouping factors. In response to a determination that the current block meets a first grouping condition, a first grouping method is selected where the first grouping method forms a first entropy coding group with one sample value of a DC transform coefficient. In response to a determination that the current block meets a second grouping condition, a second grouping method is selected where the second grouping method forms a first entropy coding group with at least two sample values, one of the sample values being the DC transform coefficient.
