Patent ID: 8665947

Claim:
A method for video-stream frame rate adaptation, comprising: allocating a buffer space for each of at least one video conference room respectively and dividing the buffer space into at least one segment, each segment of which is used for buffering a video frame; and performing following steps for each of the at least one video conference room: Step S 1 : generating a pulse signal for the video conference room periodically according to a certain pulse rate; Step S 2 : when receiving the generated pulse signal, performing a data writing operation for a first segment of the corresponding buffer space at an input-video-stream frame rate of the video conference room, and performing a data reading operation for a second segment of the buffer space at an output-video-stream frame rate; and Step S 3 : when receiving the next pulse signal generated, performing the data writing operation for the segment next to the first segment at the input-video-stream frame rate, and performing the data reading operation for the segment next to the second segment at the output-video-stream frame rate.
