Abstract: A method for variably controlling a bit rate of video data through end-to-end channel status sensing in a Wireless Broadband (WiBro) network is provided. The method includes classifying wireless channel statuses of a transmission side and a reception side into normal and abnormal statuses during video data transmission; variably controlling and determining an encoding bit rate of a transmission side's encoder according to the classification result; and comparing the determined encoding bit rate with a Down Link Modulation & Coding Selection Level (DL MCS Level) which is a parameter of the reception side, so as to vary a final encoding bit rate of the transmission side.
