摘要： The present invention is directed to an image information encoding apparatus, used in receiving compressed image information through network media when processing of such compressed image information is performed on storage media. A picture sorting buffer delivers information of picture type of frame Picture_type to a picture type discrimination unit. The picture type discrimination unit transmits command to a motion prediction/compensation unit on the basis of that information. The motion prediction/compensation unit generates predictive picture by using filter coefficients having the number of taps lesser than that of P picture with respect to B picture for which operation quantity and the number of memory accesses are required to more degree as compared to P picture on the basis of that command.

摘要： An encoding apparatus adds delay time information DTI indicating initial delay time i_d and delay time d of each group data to a position to be read prior to frame data by a decoding apparatus in the group data of encoding stream data DBI and transmits the same to the decoding apparatus 3. Namely, the encoding apparatus does not transmit initial offset delay time i_of to the decoding apparatus 3. The encoding apparatus starts to read and transmit the encoding stream data DBI from a transmission buffer at a predetermined bit rate R at timing designated by the initial offset delay time i_of.
