Patent ID: 8665738

Claim:
A transmission apparatus configured to store frame data of a first frame in a second frame having a bit rate different from a bit rate of the first frame through regulation of the amount of stuffs to be contained in the second frame, the transmission apparatus comprising: a first storage unit configured to store the frame data of the first frame; a first control unit configured to control a timing of writing the frame data of the first frame in the first storage unit based on first stuff information indicating the amount of stuffs contained in the first frame; a clock recovery unit configured to provide a read clock signal, which is generated based on the first stuff information, for reading the frame data from the first storage unit; an intermediate signal generator configured to generate an intermediate frame from the data read from the first storage unit; a second storage unit configured to store the frame data of the intermediate frame based on a write clock signal from the clock recovery unit; an arithmetic and logic unit configured to obtain second stuff information indicating the amount of stuffs to be contained in the second frame based on a bit rate ratio between the intermediate frame and the second frame; and a second control unit configured to control a timing of reading out the frame data stored in the second storage unit based on the second stuff information.
