<p>An encoding preprocessing section supplies a CPU (6) with a statistic amount (index data) representative of the feature of source video data to be encoded. Based on the statistic amount, the CPU (6) operates the difficulty of encoding video data and then operates a target encoding amount assigned to each picture of the video data based on the difficulty of encoding. The CPU (6) can perform encoding in real time without performing two encoding runs required for conventional two path encoding by feeding forward the operated target encoding amount to an encoder (4). Optimal encoding is realized depending on the pattern of the video data because the target encoding amount is operated depending on the difficulty of encoding the video data. <IMAGE></p> |
