Method and apparatus for adjusting output bit rate of video packet

An apparatus for adjusting an output bit rate of a Transport Stream (TS) packet, comprising:

• a TS processing unit for processing the TS packet;
• an output buffer for buffering and outputting TS packets processed by the TS processing unit;
• and
• a bit rate adjustment unit for separating a counting value of packet output time based on a bit rate requested by the TS processing unit into an integer part and a decimal part using a preset reference cipher according to ticks, for storing the integer part and the decimal part, for generating TS packet output signals for outputting one TS packet stored in the output buffer if a value obtained by performing a first counting according to the ticks reaches a value of the integer part, for resetting a first count value, and for decreasing the first count value by one if a carry occurs in a value obtained by performing a second counting for achieving an increment by the value of the stored decimal part whenever the TS packet output signals are generated.
