摘要： A device may be configured to perform filtering based on information included in a neural network post-filter characteristics message. In one example, the neural network post-filter characteristics message includes a syntax element indicating matrices which are present for an input tensor of a neural network post-filter. In one example, the neural network post-filter characteristics message conditionally includes a syntax element indicating a bit depth of chroma sample values, in cases where chroma matrices are present.

摘要： The present invention relates to a method for verifying video data encoded in an encoder unit, wherein the encoder unit comprises a safe part and a non-safe part, wherein loop filtering in the encoder unit is disabled, and wherein the method (1) comprises the steps of:
- Acquiring video data in the safe part of the encoder unit (2,11,21);
- Encoding the acquired video data by a non-safe encoder in the non-safe part of the encoder unit (3,12,22);
- Decoding the encoded video data by a non-safe decoder in the non-safe part of the encoder unit (4,13,23); and
- Comparing the decoded video data with the acquired video data in the safe part of the encoder unit (5,14,24), wherein a safety focused reaction is initiated if the decoded video data does not correspond to the acquired video data, and wherein a first safety sequence is generated based on the decoded video data in the safe part of the encoder unit, wherein the encoded video data and the first safety sequence are transmitted to a decoder unit for decoding the encoded video data, if the decoded video data corresponds to the acquired video data.-

摘要： L'invention concerne un procédé de codage d'une image (ICj) découpée en blocs, ladite image contenant deux zones (Z1, Z2) définies préalablement au codage de ladite image, lesdites zones étant distinctes,
ledit procédé de codage étant caractérisé en ce que l'image courante a été obtenue par projection d'une vidéo 360° et en ce qu'il met en oeuvre ce qui suit :
- coder (C6a)-C8a)) un bloc courant d'une (Zl) desdites zones, ledit codage comprenant :
- prédire le bloc courant en utilisant un bloc préalablement codé puis décodé, situé dans l'autre (Z2) desdites zones,
- coder (C100a)) une information (ibc_flag) qui indique si un mode de prédiction Intra Block Copy a été utilisé ou non pour prédire le bloc courant,
- décoder le bloc courant,
- mémoriser (C101b)) les données du bloc courant décodé en fonction de ladite information.-

摘要： An electronic device, including one or more processors configured to execute instructions; and a memory storing the instructions which, when executed by the one or more processors, configures the one or more processors to generate high-quality feature data of a current frame, by implementing a feature restoration model that is provided reference feature data, received by an electronic device, and corresponding to compressed feature data of a reference image corresponding to a first time that is different from a second time to which the current frame corresponds, and low-quality feature data received by the electronic device, and corresponding to compressed data of the current frame, that has a lower image quality than the reference image; and generate a current frame of a third image quality higher than the second image quality, based on the high-quality feature data.
