摘要： Embodiments of the present invention disclose a method and an apparatus for detecting frame types. The method includes: detecting play time of each frame; and if the play time of a current frame is less than the maximum play time of received frames, determining the current frame as a bi-directional predicted frame, B-frame. In the technical solutions provided by the embodiments of the present invention, the frame types are determined according to a coding sequence of various frames and comparison between data amounts of various frames received earlier and later, without decoding a payload. Therefore the impact of a reduction factor is eliminated and the frame types can be detected more accurately.

摘要： Embodiments of the present invention provide a video data transmission processing method, a video data sending processing method, an apparatus, and a network system. The data transmission processing method includes: receiving a source stream sent from a source transmission network to a target transmission network; performing, according to respective packet loss rates of the source transmission network and the target transmission network as well as error tolerance aid information corresponding to the source stream, error tolerance coding processing on the source stream to obtain an error tolerance stream; and sending the obtained error tolerance stream to the target transmission network. In the embodiments of the present invention, the data server can obtain error tolerance aid information corresponding to the to-be-sent stream according to packet loss rates corresponding to at least two transmission networks in the data transmission network system, so that the data forwarding node can use the error tolerance aid information to quickly generate the error tolerance stream compliant with the packet loss characteristics of the subsequent transmission network according to different packet loss rates of transmission networks, which can improve the error tolerance capability of streams in different network environments with different packet loss rates.
