摘要:
A moving picture coding apparatus includes a storing unit that stores an occupancy of a coded picture storing area in which a renderer temporarily stores coded moving picture information received at rendering of the coded moving picture information at a frame rate; a modifying unit that modifies the occupancy based on an amount of the coded moving picture information, and an amount of image data of the coded moving picture information; a deriving unit that derives a condition for the amount of the image data to allow modification at next rendering for each image unit based on a modified occupancy; a setting unit that sets an optimal coding condition of the moving picture information to be coded that satisfies the condition for the amount of the image data; and a coding unit that codes the moving picture information according to the optimal coding condition.
摘要:
A circuit design support apparatus partially converts a description of a circuit model to simulate the circuit operation. A register signal replacement section replaces a register signal with a variable in a process related with the register signal of the description and inserts a declaration of the variable in the process instead of a declaration of the register signal in the description. A clock signal simplification section replaces a clock signal with a variable in a clock signal reference process of the description and unifies a clock signal update process to the clock signal reference process in the description.

A video encoding method includes encoding n pictures included in a video image using a first quantization parameter, calculating first number-of-encoded-bits information indicating number of encoded bits of every picture type, multiplexing a set frame rate by an average first-number-of-encoded-bits per picture calculated from the first-number-of-encoded-bits information to obtain a first bit rate, encoding the n pictures using a second quantization parameter, calculating second number-of-encoded-bits information indicating number of encoded bits of every picture type, multiplexing the set frame rate by an average second number-of-encoded-bits per picture calculated from the first-number-of-encoded-bits information to obtain a second bit rate, calculating a third quantization parameter, using the first bit rate, first quantization parameter, second bit rate, second quantization parameter and target bit rate, and performing the rate control using the third quantization parameter as an initial value.

A moving picture coding apparatus includes a prediction signal generating unit that generates a prediction signal for each coding mode from an input image of an interlaced moving picture and a reference image to generate a prediction error signal; a candidate mode selecting unit that selects a candidate coding mode based on a first coding cost calculated from the prediction error signal; a tentative coding unit that calculates a bitrate for each coding mode; a coding mode control unit that determines a coding mode among candidate coding modes based on a second coding cost calculated from the bitrate; and a coding unit that performs coding according to the determined coding mode on the prediction error signal with a coding structure decided based on the second coding cost.
