    Mass video data is compressed and transferred efficiently for implementation of real-time video service. International standard (IS) was established and various methods for video data compression are being studied. But the algorithm of bit-rate control and buffer control was not established in IS. In this paper, we analyzed and compared the characteristics, the merits and demerits of various transmission control algorithms used to generate MPEG video data compressed. The concept of bit rate control and buffer control is defined explicitly for exact comparison and analysis and we propose parameters that are needed for adequate selection of algorithms to implement. As a result, the selected method is rate control algorithm of MPEG-2 video test model (TM). The algorithm is modified for simulation and implementation. Simulations present good performance. Thus the hardware implementation by using TM method is possible.
