  • Patent number: 10645410
    Abstract: While maintaining a high degree of freedom in choosing partition sizes and transformation sizes adapted for local characteristics of videos, the amount of metadata is decreased. A video encoding apparatus (10) divides an input video into blocks of a prescribed size and encodes the video block by block. The video encoding apparatus is provided with: a prediction parameter determining portion (102) that decides the block partition structure; a predictive image producing portion (103) that generates predictive images, partition by partition, as prescribed by the partition structure; a transform coefficient producing portion (107) which applies one of the frequency transformations included in a prescribed transformation preset to prediction residuals, i.e. the differences between predictive images and the input video; a transform restriction deriving portion (104) which generates the list of transform candidate, i.e.

  • Patent number: 10630999
    Abstract: To achieve a reduction in the amount of coding taken in the use of an asymmetric partition and to implement efficient encoding/decoding processes exploiting the characteristics of the asymmetric partition. In a case that a CU information decoding unit decodes information for specifying an asymmetric partition (AMP; Asymmetric Motion Partition) as a partition type, an arithmetic decoding unit is configured to decode binary values by switching between arithmetic decoding that uses contexts and arithmetic decoding that does not use contexts in accordance with the position of the binary values.

  • Patent number: 10547861
    Abstract: A video image decoding device (1) is equipped with a TT information decoder (14) that, in the case where encoded data includes merge/skip information that merges or skips presence information indicating whether or not frequency-domain transform coefficients are included in the quantized transform coefficients, does not decode the presence information, and a TT information inference unit (33) that, in the case where the encoded data includes merge/skip information that merges or skips the presence information, infers the presence information. The TT information decoder (14) uses presence information inferred by the TT information inference unit (33) to decode the encoded and quantized transform coefficients.
