Abstract: This application provides a media data transmission method and an apparatus. The method includes: A client sends first information to a server. The client receives video data packets that correspond to a second target video picture and that are sent by the server. The first information is used to indicate spatial information of a region in which a first target video picture is located, and the first target video picture includes a video picture within a current viewport. The second target video picture includes the first target video picture, at least one of the video data packets corresponding to the second target video picture carries at least one piece of second information, and the second information is used to indicate spatial information of a region in which the second target video picture is located.

Abstract: A device for encoding and a device for decoding a picture, respectively, and corresponding methods relating to the field of picture coding are provided. The devices are respectively configured to partition the picture into one or more slices, each slice comprising one or more tiles, and one or more slices holding coded picture data. Further, the devices are configured to encode the one or more slices holding coded picture data, thereby improving coding and decoding of pictures with uncoded buffer space.

Abstract: A method of video encoding a sequence of pictures, the method being implemented in an encoding device and comprising: obtaining an intra prediction picture comprising at least two sub-units; obtaining a first encoded other picture, wherein the intra prediction picture and the first encoded other picture have the same Picture Order Count, POC, value; obtaining encoded other pictures different from the intra prediction picture and the first encoded other picture; and distributing the at least two sub-units of the intra prediction picture over one or more sub-units of the encoded other pictures and/or over one or more sub-units of the first encoded other picture.
