Problems solved by technology

[0006] However, for remote video program production, such as the World Cup program production, the production unit usually rents a huge communication bandwidth to transmit program information. If there is a problem with the front-end program production, it may re-communicate, re-produce, and re-transmit the program, wasting manpower and bandwidth. (money) and time

Abstract

The invention discloses a method, a device and a system for collaboratively editing video and audio. The method for collaboratively editing the video and the audio comprises the following steps: a transmitting terminal and a receiving terminal build the visual telephone communication; the transmitting terminal selects the video and audio files, generates the editing information according to the editing operation and transmits the information to the receiving terminal; and the transmitting terminal executes the editing operation, edits the video and audio files, and transmits the video and audio files after being edited to the receiving terminal. The invention realizes the video and audio transmission and sharing among the terminals and the collaborative edition of the remote video and audio programs, further meets the burstiness and the real-time performance of programming, and prevents re-communication, preparation and transmission caused by the problems produced during the programming process of the transmitting terminal, so that the bandwidth and the time of the communication are saved, and the cost needed by transmitting the remote video and the audio is further reduced.

Description

technical field [0001] The invention relates to a data service technology, in particular to a video and audio collaborative editing method, device and system. Background technique [0002] Videophone is an important business application in mobile terminals in the 3G era. Its characteristic is that both terminals can communicate with each other through video and voice in real time. The underlying communication protocol of videophone conforms to the definition of 3GPP3G-324M standard. [0003] Ordinary video program editing mainly includes two steps: 1) collecting, recording video programs through video recording and storage devices; 2) editing, using editing equipment to browse and edit video programs for collected video materials. Among them, the current editing technology is based on digital video and audio materials, which are edited in a non-linear manner. The main feature of the so-called non-linearity is that it is possible to access any position of the material at onc...
