Abstract:
A video encoding apparatus comprising:encoding means for encoding an input picture signal and outputting encoded data;output buffer means for temporarily holding the encoded data and for outputting the encoded data at a transmission rate;first control means for determining the target number of encoding bits using the transmission rate and a frame rate in order to set, within a limit delay time, a delay in outputting the encoded data held in the buffer means at the transmission rate, and for controlling the number of encoded bits generated by the encoding means, in accordance with the target number of encoding bits; andsecond control means for skipping the input picture signal input to the encoding means in units of frame until the number of coded bits held in the output buffer means reaches a value determined by the transmission rate, the limit delay time and the encoding frame rate, thereby to control a frame rate in accordance with the number of coded bits.
