Title:
CONTROLLER FOR VIDEO SIGNAL CODING SYSTEM
Document Type and Number:
Japanese Patent JPH0974565
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a controller for video encoding system which calculates a quantization parameter and decides an inter/intra-mode and a field/frame DCT mode. SOLUTION: A state machine 120 generating a control sequence containing plural control signals in accordance which signals showing the type of encoded picture and the start of the picture, an arithmetic unit 130 calculating a group of expressions which are previously decided based on the sequential number of a macro block which is encoded in accordance with the control sequence and an initial constant value and generates the group of control values showing the inter/intra-mode, a field/frame mode and the quantization parameter and a memory and an input/output unit 140 for storing the initial constant value, supplying the initial constant value to the arithmetic unit, storing the control value obtained in the arithmetic unit 130 and supplying the control value used in video encoding are contained in the controller.
