摘要： A receiving apparatus receives a bitstream that is divided into units encoding a moving picture and includes a stream header indicating how the units are to be decoded. The receiving apparatus estimates the contents of the stream header from the contents of the units, so that decoding of the units can begin before the stream header is received. The receiving apparatus preferably checks for errors in the analysis and decoding of the units, and modifies the estimated stream-header information when an error is discovered. The same unit may be analyzed and decoded repeatedly to hasten the correct estimation of the stream-header information.

摘要： Moving picture encoding method and apparatus in which deterioration in quality of a moving picture which is decoded by a decoding apparatus can be suppressed by effectively making the most of a transmission band under limitation of a transmission band of a transmission path are provided. The apparatus calculates a prediction code amount with respect to each frame constructing a moving picture. A target code amount upon encoding of the current frame is calculated on the basis of a predetermined target bit rate or code amount information regarding a preceding frame. An area to be encoded of the current frame is determined on the basis of the target code amount and the prediction code amount.
