Title: Bandwidth Adaptation Transcording Method using Frame Dropping Ratio
Inventor: HAN TAE MAN
IPC: H04N7/12
Filed: 2000-12-30
Abstract: PURPOSE: A bandwidth adaptive transcoding method using a frame drop rate is provided to compare a frame transmission number calculated based on a regular time interval with a reference frame number, to obtain the frame drop rate, and to decide a size of a video frame appropriately for a traffic condition of an accessing Internet user for transmission. CONSTITUTION: A VOD(Video On Demand) server transmits video stream on the request of an Internet user(201). A transcoding server analyzes an MPEG(Moving Picture Experts Group) 1/2 header(202) and a frame header, and increases a counter(fc) of a frame number and a value(tc) of a self-timer(203,204). Whether the value of the self-timer reaches a reference time(T) is checked(205). If not, video transmission is performed and the steps of 203 to 205 are repeated. If the value of the self-timer reaches the reference time, a transmission frame number(f) per second is calculated(207). A frame counter is initialized(208), and a difference between a reference frame number(F) and the frame transmission number is checked(209). If the frame transmission number is smaller than the reference frame number, transcoding is not performed and the 203 step is returned while continuously transmitting frames. If the frame transmission number is larger than the reference frame number, a frame drop rate(D) is calculated by subtracting the frame transmission number from the reference frame number(210). Transcoding based on frame dropping is performed on the basis of the calculated frame drop rate(211).
