  • Patent number: 11910039
    Abstract: An encoding engine encodes a video sequence to provide optimal quality for a given bitrate. The encoding engine cuts the video sequence into a collection of shot sequences. Each shot sequence includes video frames captured from a particular capture point. The encoding engine resamples each shot sequence across a range of different resolutions, encodes each resampled sequence with a range of quality parameters, and then upsamples each encoded sequence to the original resolution of the video sequence. For each upsampled sequence, the encoding engine computes a quality metric and generates a data point that includes the quality metric and the resample resolution. The encoding engine collects all such data points and then computes the convex hull of the resultant data set. Based on all convex hulls across all shot sequences, the encoding engine determines an optimal collection of shot sequences for a range of bitrates.

  • Patent number: 11818191
    Abstract: An approach for gathering, encoding and transmitting histogram data mitigates the need for transmission resources by compressing the gathered data in a lossless, stateless manner for transmission. A generally sparse data set benefits from an encoding mechanism based on a bit plane arrangement of the raw data. The approach organizes bit planes in a sequential manner, and then encodes values based on intervals of non-zero bit positions. By traversing a sequential string based on the bit plane, each “run” of zeroes tends to produce relatively small values, easing encoding burdens, but also accommodated larger values when necessary. A selective encoding technique invokes different encoding processes based on the magnitude of the interval, to allow use of an encoding that stores each respective value in the fewest bits. Different encoding techniques are applied based on ranges of the interval magnitude, or zero run.

  • Patent number: 11785264
    Abstract: A better compromise between encoding complexity and achievable rate distortion ratio, and/or to achieve a better rate distortion ratio is achieved by using multitree sub-divisioning not only in order to subdivide a continuous area, namely the sample array, into leaf regions, but using the intermediate regions also to share coding parameters among the corresponding collocated leaf blocks. By this measure, coding procedures performed in tiles—leaf regions—locally, may be associated with coding parameters individually without having to, however, explicitly transmit the whole coding parameters for each leaf region separately. Rather, similarities may effectively exploited by using the multitree subdivision.

  • Patent number: 11523118
    Abstract: There is provided a method for encoding and decoding a signal. The input signal (1000) is processed by at least converting the input signal (1000) from a high-dynamic range—HDR-signal to a standard dynamic range—SDR-signal, to produce a first processed signal. The first processed signal is encoded by a first encoding module (1004) to generate a first encoded signal (1012). The first encoded signal (1012) is decoded to generate a first decoded signal. The first decoded signal is processed together with the first processed signal by a second encoding module (1006) to generate a second encoded signal (1014). The second encoded signal (1014) is decoded and the result is combined with the first decoded signal (1012) to generate a second decoded signal. The second decoded signal is processed at least by converting the second decoded signal from a SDR signal to a HDR signal, to produce a second processed signal.

  • Patent number: 11509902
    Abstract: There is provided a method for processing an input signal (700). The input signal (700) is processed at least by converting the input signal (700) from a first colour space to a second colour space, to produce a first processed signal. The processed signal is encoded by a first encoding module (703) to generate a first encoded signal (710). A decoded signal is generated by decoding the first encoded signal (710). The decoded signal is processed at least by converting the decoded signal from the second colour space to the first colour space to produce a second processed signal. The second processed signal and the input signal (700) are processed by a second encoding module (707) to generate a second encoded signal (720).

  • Patent number: 11470299
    Abstract: A method and system for encoding a stereoscopic image pair is disclosed. Groups of pixels are analyzed to determine the depth of each pixel group. The number of bits per pixel used to encode each pixel group is selected based on the depth of that pixel group. Therefore, images of objects closer to the camera pair, which appear closer to the viewer, are encoded with a larger number of bits per pixel than objects perceived to be farther from the viewer. The number of bits per pixel may also be increased based on a number of objects depicted or motion detected. The size of prediction blocks used to encode image portions may also be determined based on an angular distance of an image portion relative to the center of the frame. Therefore, smaller prediction blocks may be used to encode image portions closer to the center of the frame.

  • Patent number: 11451813
    Abstract: Innovations in syntax and semantics of coded picture buffer removal delay (“CPBRD”) values potentially simplify splicing operations. For example, a video encoder sets a CPBRD value for a current picture that indicates an increment value relative to a nominal coded picture buffer removal time of a preceding picture in decoding order, regardless of whether the preceding picture has a buffering period SEI message. The encoder can signal the CPBRD value according to a single-value approach in which a flag indicates how to interpret the CPBRD value, according to a two-value approach in which another CPBRD value (having a different interpretation) is also signaled, or according to a two-value approach that uses a flag and a delta value. A corresponding video decoder receives and parses the CPBRD value for the current picture. A splicing tool can perform simple concatenation operations to splice bitstreams using the CPBRD value for the current picture.

  • Patent number: 11438615
    Abstract: A decoding device includes a transformer sets a decoded luminance component of a prediction target block to the same number of samples as that of the chrominance component corresponding to the decoded luminance component of the prediction target block and generates a luminance reference signal. A specificator specifies luminance pixels having minimum and maximum pixel values of the decoded luminance component adjacent to the decoded luminance component of the prediction target block, respectively, outputs luminance pixel values obtained from specified luminance pixels, and outputs chrominance pixel values from pigment pixels corresponding to the luminance pixels. A derivator derives a linear prediction parameter from the two pixel values and a linear prediction model. A chrominance linear predictor obtains a chrominance prediction signal by applying the linear prediction model based on the linear prediction parameter to the luminance reference signal.
