Abstract:
An encoder apparatus comprising:an encoder for compressing and encoding multiple moving pictures and calculating the number of bits used to obtain encoded data by encoding each said picture to be encoded; original picture data storage for storing the pictures to be encoded thereon; encoded data storage for storing the encoded data thereon; and a bit number comparator for obtaining a threshold value of the number of bits available for each said picture to be encoded and determining whether or not the bit number exceeds the threshold value, wherein if the encoder has determined that there will be enough time for the encoder to re-encode a current one of the pictures to be encoded before encoding of a next one of the pictures is started and if the comparator has found the bit number exceeding the threshold value, then the encoder re-encodes the current picture by changing encoding parameters in such a manner as to reduce the bit number.
