A system and a method transfer multiple data channels between a server and a terminal via a stream session over a network. The system and the method utilize a bitstream switching, a fast buffer filling and/or a fast playback start to facilitate a switch from a first data channel and a second data channel. The first data channel and/or the second data channel is delivered to and/or is transferred to the terminal from the server over the network via a streaming session. The server transfers second data of the second data channel to the terminal via one or more tracks which are encoded at more than one bitrate and/or are configured in one or more configurations. The terminal requests a change between the first track and/or the second track without terminating the stream session for the first data channel between the terminal and the server. As a result, the system and/or the method minimizes the delay period of time between requesting the switch to the second data channel and displaying the second data channel.

The invention provides an event-oriented intelligent camera monitoring method. The method includes the steps that after video capture is conducted, processing is carried out, three code streams are obtained, the three code streams include a low-resolution video, high-definition images which are spaced by a plurality of seconds and a high-definition moving object image, and the three code streams are displayed on a display terminal independently or are displayed on the display terminal after being overlaid and fused. By means of the event-oriented intelligent camera monitoring method, one video which is much shorter than an original video can be provided, and the browsing time is greatly shortened; event clues can be searched for quickly according to the information such as time, and thus the investigation and evidence collection efficiency is improved; space information in the scene is fully utilized, space-time redundancy in the video is reduced, events which happen at different periods of time are displayed at the same time, and activities in the video can be understood and grasped easily; activities and events in the original video cannot be lost, and the effects that fast playing can be achieved and video information cannot be lost are achieved; the code stream bandwidth and the definition of special areas are both considered, hence, powerful support is provided for evidence collection after events, and a wide application requirement for the method can be met in the video security and protection monitoring field.

The invention discloses a multi-screen video synchronous playing method and device. The method comprises the steps that an ultrahigh-resolution-ratio video source is divided into small equant videos to be placed on different node computers, video data are converted into YUV image sequences, and the same number is used for identifying the same frame of sequences of all the small videos; a YUV file is generated from the YUV image sequences; a main control computer sends instructions to all the node computers to enable all the node computers to play the videos at the same moment; a camera starts to synchronously shoot a whole video picture and analyze the numbers of frames; when the frames with different numbers exist, the main control computer sends instructions to the node computer with the different frames to correct the serial numbers of the frames needing to be played, and the image sequences of the frames needing to be played are extracted from the node computer so as to achieve the purpose that the numbers of all the frames of the same picture are uniform.

A control information decoding section (102) decodes sets of control information contained in a stream. Further, a random access information analyzing section (101) carries out analysis of locations of random access points of media items contained in the stream, on the basis of the sets of control information. Still further, a management information generating section (103) generates management information for managing a plurality of random access points contained in the stream, on the basis of decoded versions of the sets of control information, which has been obtained by the control information decoding section (102), and the locations of the random access points obtained by the analysis performed by the random access information analyzing section (101). Then, the management information thus generated and the stream are recorded onto a storage medium (104). This makes it possible to quickly start playback in performing random-access playback of a stream into which control signals are inserted at regular intervals.
