基于标准的H.264和/或VC1视频编码的可编程量化死区和阈值

Programmable quantization dead zone and threshold for standard-based H.264 and/or VC1 video encoding
摘要:
A video encoder is disclosed that includes an encoder circuit, a quantizer circuit and a control circuit. The encoder circuit may be configured to generate a number of coefficient values in response to a video stream and a number of quantized values. The quantizer circuit may be configured to generate the number of quantized values in response to the coefficient values, two or more quantization dead zones and two or more offsets. The control circuit may be configured to set the two or more quantization dead zones and the two or more offsets to different values. The two or more quantization dead zones and the two or more offsets are independently programmable.
