A protocol and related techniques and platforms allow vendors to selectably extend the Media Transport Protocol (MTP), or other defined protocols to implement vendor-specific commands, data fields, instructions and other extension sets. According to embodiments of the invention in one regard, one or more extension space may be utilized to derive independent extension sets, in part by separating the extension space according to a unique identifier assigned to or associated with a given vendor. In embodiments that unique identifier may be or include an Internet DNS (Domain Name System) domain name, or other extension set name or identifier. According to the invention in one regard, because a DNS domain name may be independently registered and secured by participating vendors or manufacturers and by definition uniquely assigned, the separation of vendor extension sets by that type of name may be automatic and free from conflict. Vendors or manufacturers, such as makers of digital cameras, digital video cameras, audio players such as MP3 or other players, software vendors or others may therefore freely design extensions to the Media Transport Protocol or other protocols, without a need to clear those extensions with a standards body and with confidence that their commands, data fields and other extensions may be free from overlap with that of other manufacturers.

The present invention relates to a method and terminal for reporting media format adaptation resources to convert a media format of a media stream of a media session to be established between terminals through a packet switched communications network towards a requesting terminal. The invention further relates to a method and NSIS router for reporting media format adaptation resources for converting a media format of a media stream of a media session to be established between terminals. To allow terminals to establish a media session utilizing media adaptation, the invention provides a NSIS (Next Step In Signaling) based signaling framework facilitating the detection and reservation of media adaptation resources on (and off) a media data path on which media data are transported utilizing a media transport protocol among terminals participating in the session.

The embodiment of the invention discloses a method, device and system for streaming media transmission and relates to the field of communication technologies. According to the method, device and system for streaming media transmission, the problems that a preconfigured transmission protocol of streaming media data transmitted between a network side service and a terminal is unsuitable for application in a network currently connected with the terminal, so the efficiency of streaming media data transmission is lowered, the quality for watching a media program through the terminal by a user is poor, and the user cannot normally watch the media program can be solved. The method comprises the steps that at least two types of streaming media transmission protocol information contained in streaming media information corresponding to a media program are acquired; network connection type information of a terminal is acquired; according to the network connection type information, a first transmission protocol corresponding to the network connection type is determined from at least two types of streaming media transmission protocols; a broadcasting request of the media program is transmitted to a streaming server; the media program transmitted by the streaming server through the first transmission protocol is broadcast. The method, device and system for streaming media transmission are suitable for streaming media service systems.

The invention discloses a method for detecting the packet loss of an H.264 video file. The method comprises the following steps that: 1, the H.264 video file consists of a plurality of video sequences each of which includes a plurality of I, P and B frames, and measurement information is inserted into the video sequences by utilizing a user data domain; 2, a receiving end acquires a data packet load for transmitting the H.264 video file and the size of each frame through the measurement information; and 3, after the reception, the total number of data packets for transmitting the H.264 video file is obtained according to results obtained by the step 2, and is compared with the number of the data packets received by the receiving end so as to obtain a packet loss rate. In the method for detecting the packet loss of the H.264 video file, the valid measurement information is written into the user data domain, so that the packet loss condition of the H.264 video file can be accurately detected without the restriction of a stream media transmission protocol; and due to redundant data embedded in video, the accuracy of a measured value is ensured and an introduced measurement load is minimal.

In order to make pressure test possible to measure performance and quality of media server for responding requests of clients in overall and precisely, the method executes following procedures: first, setting up RTSP URL list requested by test tools, and number of client end for requesting each URL; next, setting up operation sequence for carrying out RTSP request by test tool; then, based on parameters set up in previous steps, test tool sends out RTSP request; making statistics of RTSP, and relevant data of media transmission in real time, and displaying them on control interface; final, carrying out statistics process for tested result by using test tool so as to form test report. In the invention, parameters can be included in URL character string of RTSP request; redirection function is supported; based on RTP protocol or other media transmission protocol, quality of media data stream can be analyzed.

The mobile receiving device (MRD) in dual mode includes following parts: wireless digital broadcast reception process module (WDBRPM) receives wireless digital broadcast signal from digit broadcast signal source, and carries out transmittal de-multiplexing process for the signal, picks up media stream signal, and outputs the processed signal to selector; IP stream media reception process module (SMRPM) receives and sends data stream signal based on IP from / to IP network, processes the signal according to stream media transport protocols and picks up signal of media stream, and outputs the processed signal in format of media stream to a selector; the selector receives signals of media stream from WDBRPM and IP SMRPM, and selects one route of signal of media stream. The invention also discloses method for implementing reception by MRD in dual mode. Using time symbol and frame sequence number in switching time, the method maintains continuity of frame to realize seamless switching.
