A context-based adaptive variable length coding device for H.264/AVC

摘要

PURPOSE: A variable length encoding unit based on content for H.264 and AVC codec is provided to reduce manufacturing costs by reducing the size of hardware and memory size. CONSTITUTION: A first dual buffer unit(11, 12) includes an upper buffer unit. A second dual buffer unit(13, 14) includes a lower buffer unit. An operation processing unit manages an encoding process. A bit stream buffer unit(21) stores a processed result value. A control unit(15) creates a control signal and enable signal in order to control an encoding unit.
