Patent ID: 8493429

Claim:
A method for synchronously recording voices and images of an opposite end based on a circuit domain videophone, comprising steps of: receiving, by a terminal used by a party in a video call, a recording instruction sent by a user, taking a local time as a reference time, and performing frame analyzing for received audio and video code-streams; and writing audio frames and video frames obtained by analyzing, as well as a duration corresponding to each frame, into a 3GP file; wherein, the duration of each of the audio or video frames except the first audio or video frame written into the 3GP file is respectively a difference between a relative time when the audio or video frame is obtained by analyzing and d relative time when a previous frame corresponding to the audio or video frame is obtained by analyzing, and the value of the relative time when each of the audio or video frames is obtained by analyzing is respectively a difference between a local time when the audio or video frame is obtained by analyzing and said reference time.
