IPC: H04N19/102
Filed: 2002-03-09
Abstract: PURPOSE: A method for encoding a moving picture is provided to uniformly distribute an intra block in the whole frame in changing intra block update intervals, thereby uniformly maintaining a bit amount between frames. CONSTITUTION: A previous update interval is taken as an i1 variable, the new update interval as an i2 variable, and a variable mb is initialized as zero(S201). It is judged whether the previous update interval is larger than the new update interval(S202-S203). If so, a counter value of the current MB(Macro Block) is multiplied by the new update interval and thereafter divided by the previous update interval to set the result as a counter value of a new MB, and mb is increased by 1(S204). If not, a quotient obtained by dividing the new update interval by the previous update interval is taken as a q variable, and an r variable by subtracting a value of multiplying the previous update interval by q from the new update interval(S206). If the r value is zero, an r2 variable is obtained by multiplying the counter value of the MB by q, an r1 variable by subtracting a 'q-1' value from the r2 variable, and a random value between the r1 and the r2 to be set as a counter of a new MB(S208). A 'gcd' value is obtained by calculating the greatest common measure of the previous update interval and the new update interval, and a k variable by taking the smaller value of 3 and a value of dividing the previous update value by the gcd(S210).
