Abstract: The present invention provides a method and an apparatus for acquiring 3D format description information. The method includes: receiving an out-of-band message that carries 3D format description information and is sent by a sending end, where the out-of-band message is received before a client participates in a multimedia session initiated by the sending end; and parsing the out-of-band message and acquiring the 3D format description information from the out-of-band message. The client may determine, before the video is received, whether the client matches a format used for a 3D video. This improves the speed of determining the match, reduces the overhead of receiving and processing the video.

Abstract: Embodiments of the present disclosure include a media display control method and a related product. The method includes: after a call between a first terminal and a second terminal rings, obtaining candidate media information from a resource server, and displaying the candidate media information; determining first to-be-displayed media information after the call between the first terminal and the second terminal is connected, where the first to-be-displayed media information is media information selected from the candidate media information; and sending, by the first terminal, the first to-be-displayed media information to the second terminal. Media information displayed by the terminals may be controlled after the call between the terminals is connected, so that the displayed information is controlled during the call. In this way, valuable information is displayed to the user, and communication efficiency is improved.

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.

Abstract: A fingerprint anti-counterfeiting method and an electronic device are provided. The fingerprint anti-counterfeiting method includes: After detecting a fingerprint input action of a user, an electronic device obtains a fingerprint image generated by the fingerprint input action, and obtains a vibration-sound signal generated by the fingerprint input action. The device determines, based on a fingerprint anti-counterfeiting model, whether the fingerprint input action is performed by a true finger. The fingerprint anti-counterfeiting model is a multi-dimensional network model obtained through learning based on fingerprint images for training and corresponding vibration-sound signals. The fingerprint anti-counterfeiting method in embodiments of this application helps improve a protection capability of the electronic device for a fake fingerprint attack.

Abstract: The present invention 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.
