Problems solved by technology

When a terminal plays a video CRBT, it usually adapts the playback resources based on the information in the video media stream. Before the arrival of the initial video stream, the terminal cannot prepare appropriate resources in advance.
When the initial video stream arrives, the terminal can only play the video CRBT according to the existing playback resources. Since different video CRBT files may have different video parameters, such as different resolutions, the video CRBT can be played on terminals with different resolutions. If the resolution currently set by the terminal does not match the resolution of the video CRBT file, there will be image playback distortion, playback freezes, etc., which will reduce the playback quality and even cause the video CRBT file to fail to play.

Abstract

The embodiment of the invention discloses a video polyphonic ringtone playing method which comprises the following steps: under the condition that a calling request of a calling terminal is received,determining a video polyphonic ringtone file of the calling terminal; Obtaining video parameters of the video polyphonic ringtone file; Sending the video parameters to the calling terminal; Wherein the video parameters are used for indicating the calling terminal to prepare for playing the video polyphonic ringtone file. Therefore, the terminal can prepare for playing the video polyphonic ringtonefile according to the video parameters received in advance, so that the playing success rate and the playing quality of the video polyphonic ringtone file are ensured. The embodiment of the inventionalso discloses a video polyphonic ringtone playing device and a video polyphonic ringtone playing system.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method, device and system for playing video ring back tones. Background technique [0002] With the development of science and technology, terminals with various resolutions emerge in an endless stream, and the CRBTs that the terminals can receive have also developed from audio CRBTs to video CRBTs. When the terminal plays the video ring back tone, the playing resource is usually adapted according to the information in the video media stream. Before the arrival of the initial video stream, the terminal cannot perform proper resource preparation in advance. When the initial video stream arrives, the terminal can only play the video CRBT according to the existing playback resources. Since different video CRBT files may have different video parameters, such as different resolutions, the video CRBT can be played on terminals with different resolutions. At this time, if the re...
