Abstract
An embodiment of the present invention discloses a recording and broadcasting system. The system comprises conference terminals set in all conference venues, a conference controller connected with each conference terminal, and a centralized recording and broadcasting device connected with the conference controller. Each conference terminal collects an audio and video signal of the corresponding conference venue, converts the audio and video signal into an audio and video IP data package of the corresponding conference venue, and sends the audio and video IP data package to the conference controller. The centralized recording and broadcasting device acquires the audio and video IP data package from the conference controller, and performs synchronous recording so as to convert the audio and video IP data package into an audio and video stream media file of the corresponding conference venue. The conference terminal set in corresponding conference venue transmits the audio and video signal of the corresponding conference venue to the conference controller. According to the recording and broadcasting system, the audio and video IP data package of the corresponding conference venue is directly acquired from the conference controller with only one centralized recording and broadcasting device, and then the audio and video IP data package is converted into the audio and video stream media file that can be played and is of the corresponding conference venue, so that the audio and video of each conference venue are recorded, and the hardware resource is saved.
