摘要： A moving image processing system includes an encoding apparatus encoding a moving image by encoding a picture order count (POC) while inserting a recovery point, and a decoding apparatus decoding the moving image encoded by the encoding apparatus. The encoding apparatus includes an insertion permission/rejection determining unit that determines whether a decoded frame is a reference frame and its frame number from an instantaneous decoding refresh frame is a positive integer times as large as a number of reference frames within a POC cycle, and a recovery point inserting unit that inserts the recovery point into the frame depending on a result of determination by the insertion permission/rejection determining unit. The decoding apparatus includes a POC decoding unit that decodes the POC by executing an initializing process such that the frame number within the POC cycle used in decoding the POC becomes zero, when decoding by random accessing is started.

摘要： A signal processing apparatus converts interlaced 4:2:2-format video signals including a luminance component and two chroma components into interlaced 4:2:0 format video signals. A downsampling low-pass filter has such a group delay that a modulo-1 remainder of the group delay at frequency ω=0 is substantially equal to 0.25. The downsampling low-pass filter is designed together with an associated upsampling low-pass filter such that the first downsampling low-pass filter and the upsampling low-pass filter substantially satisfy perfect reconstruction filter bank condition, and such that a sum of the group delay of the first downsampling low-pass filter and a group delay of a normalized filter obtained by making the sum of all the coefficients of the upsampling low-pass filter equal to 1 is substantially equal to an integer number at frequency ω=0.

The encoding apparatus includes a remainder calculating unit that calculates a remainder by dividing an absolute frame number counted from an instantaneous decoding refresh (IDR) picture by a divisor which is a number of reference frames in one POC cycle, and a remainder code converting unit that coverts the remainder calculated by the remainder calculating unit into a code. A decoding apparatus decodes image data using the POC. The decoding apparatus includes a remainder extracting unit that, when random access decoding is performed, extracts a remainder by decoding a remainder code added to a picture at a random decoding start position, and an initializing unit that initializes an input value of a decoding process for the POC, by using the remainder extracted by the remainder extracting unit.
