Problems solved by technology

[0006] 1. After the film to be played is transmitted to the receiver, if there is a change at the sender, it cannot be immediately reflected to the receiver;
[0007] 2. If the content of the film is confidential and the sender does not allow the receiver to keep a copy, the technical solution is invalid;
[0011] 1. It takes a huge storage space to record the film image completely in the form of active code stream;
[0012] 2. Need to use additional equipment for data storage;
[0018] 3. In the multi-point receiving mode, playback requests from multiple receivers will seriously affect the film playback performance of the sender

Embodiment Construction

[0049] In the embodiment of the present invention, by setting paging information for the film sent in the video conference system, the receiving end can save the content of the film in the form of a single picture according to the paging information, so as to play back the received content in the same film. The paging information can be set by the sender or by the receiver.

[0050] In order to ensure the security of the film to be sent, the sender can set the confidentiality level and send a confidential announcement to the receiver before sending the film, so that the receiver can save or copy the film according to the sender's requirements. The confidentiality level can be set according to the requirements of the actual sender. Different levels allow the receiver to have different operation rights. If the sender does not allow the receiver to save or copy the content of the sent film, no paging information will be sent, and the receiver is not allowed to set Pagination info...

Abstract

The invention relates to a kind of film transmission method, device and system in field of communication technique. Sending side obtains current paging information of current sent film; during course of sending film, send paging information of said film. Receiving side receives the film, judges whether the paging information is received; if the paging information is received, current single film is saved, and play current film or play back saved film based on demand of user; if else said film will not be saved. The invention realizes the safety, practicability and flexibility of film transmission in conference TV system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a film transmission method, device and system in a video conference system. Background technique [0002] Conference TV system is an interactive multimedia information service integrating voice, image and data, and a value-added service based on communication network. In a meeting conducted with a video conference system, the participants are distributed in different geographical spaces, and the real-time mutual communication and transmission of voice information and image information of the participants can be realized through the video conference system. According to the geographical distribution of participants, conferences can be divided into two-party conferences (point-to-point conferences) and multi-party conferences (multipoint conferences). [0003] The film transmission function is often needed in the conference conducted by the video conferencing system, so tha...
