The present disclosure provides a data transmission method of a system in an IP based broadcasting network, the data transmission method comprising the steps of: generating an MPEG media transport protocol (MMTP) packet using a media processing unit (MPU) for a service; generating an IP packet using the MMTP packet; generating a layer 2 (L2) packet using the IP packet and generating a layer 1 (L1) packet stream using the L2 packet; and transmitting the L1 packet stream, wherein absolute time information of the system is included in one of a transmission frame of the L1 packet stream and the L2 packet.

There are provided a multi-point conference system and a multi-point conference device capable of using an SIP terminal as a conference terminal and clearly and smoothly performing speaker switching without requesting a conference terminal to transmit an intra frame when a speaker is detected. The multi-point connection device includes an image processing unit for accumulating in a memory (13), image data from the conference terminal participating in the conference, and decoding the image data on the speaker accumulated in the memory (13) and re-encoding the decoded image upon detection of a speaker in a medium processing unit (15). Upon switching of a speaker, the image processing unit re-encodes the first image as an intra frame and transmits the image data to conference terminals other than that of the speaker, so that the conference terminals other than that of the speaker can perform decoding from the intra frame, thereby clearly and smoothly performing the speaker switching.

The invention can satisfy people's demand for fast, smooth and dynamic operation, and let people experience the convenience and comfort of a digital home anytime and anywhere.

The invention discloses a method and a device for audio processing of a conference system. The method comprises the following steps of receiving audio code streams sent by a terminal side, wherein each audio frame of the audio code streams carries corresponding audio information; analyzing the audio information corresponding to the current audio frame to obtain an analysis result; judging whether an effective voice message exists in the analysis result, wherein the effective voice message is used for representing an audio frequency emitted by speaking of a participator; and decoding the current audio frame when the effective voice message exists in the analysis result. Through judging whether the effective voice message, namely voice, exists in the audio code streams, all speaking information of the participators can be decoded, and the complete decoding of the audio code streams sent by the terminal side can be avoided, so that the resource consumption of a media processing unit is reduced; and the discard of the audio code streams having the smaller volume and belonging to the personal voice can be avoided, so that the audio processing effect of the conference system is improved.

The invention discloses a backup method for media processing units in a multipoint control unit MCU, a multipoint control unit and a video communication system. The method comprises the following steps: a multipoint processor MP in the MCU detects the state of a corresponding media processing unit by periodically polling the status message reported by each media processing unit in the MCU; and ifthe current media processing unit is detected to be out of service, the work of the media processing unit with failure is interrupted through the MP to select a new media processing unit, parameters used by the media processing unit with failure and a corresponding terminal thereof are transmitted to the new media processing unit, and the new media processing unit is started to replace the media processing unit with failure to conduct media service processing. By adopting the method, after the media processing units are out of service, the terminal is called without waiting for the MCU, or theMCU does not need to be called by the terminal, therefore, the latency time of the users is reduced, and the seamless connection at the side of the MCU is realized.

The invention provides a web real-time communication media processing method and device. In a multiuser real-time multimedia communication scene, the client processing load is reduced, and the network bandwidth consumption is reduced.
