Abstract: The present disclosure discloses a video encoding and decoding method, apparatus and system, where the video encoding method includes: determining an independently decodable view in a to-be-encoded picture according to a configuration file corresponding to the video; dividing the picture into at least two tiles, where an area corresponding to one or more tiles that cover the independently decodable view is an independently decodable area; generating an auxiliary message corresponding to the picture, where the auxiliary message includes a location identifier of the independently decodable area; and encoding all tiles included in the picture to form an encoded video bitstream, where the encoded video bitstream includes the auxiliary message. Decoding this encoded video bitstream can lower a requirement for performance of a decoder and improve decoding efficiency.

Abstract: This application discloses a roaming charging method and apparatus. A blockchain network stores information related to roaming fee settlement, to reduce a possibility that the information related to roaming fee settlement is tampered with. In addition, a digital signature algorithm is used to sign roaming service statistics to generate an abstract, to further prevent the roaming service statistics from being tampered with. In this way, when a home carrier verifies a roaming account balance by using the roaming service statistics and a roaming charging rule, accuracy of a verification result can be ensured, and the home carrier can obtain an accurate roaming fee of a user.

Abstract: This application provides an interaction information transmission method and apparatus. The method includes: receiving, by a calling terminal from an RBT-AS, an SDP message including interaction information related to a video ring back tone; receiving, by the calling terminal from the RBT-MRS, a video ring back tone media stream including the video ring back tone; and playing, by the calling terminal, the video ring back tone in a display interface, and displaying interaction content related to the interaction information. Since the RBT-AS configures the interaction information into the SDP message and sends the SDP message to the calling terminal, the calling terminal does not need to perform decoding and can directly obtain the interaction information and the RBT-AS does not need to encode the interaction information either. Therefore, encoding and decoding processes are not required at a transmit end and a receive end respectively, avoiding extra processing overheads.
