Abstract

Provided is an enhancement to the Video Encoder component of the MPEG standard to improve both the efficiency and quality of the video presentation at the display device.

Claims (15)

1. A method for allocating bits to a frame in a video encoder implementation, comprising:

determining a first number of bits for a frame to achieve a target bit rate according to a first procedure that produces values for a number of header bits, a number of run-level pairs and a number of DCT bits; and

determining a second number of bits for the frame, wherein the determination is based on an actual number of coded zeros for the frame to match the number of DCT bits; and

allocating the second number of bits to the frame.

2. A method for allocating bits to a frame in a video encoder implementation, comprising:

determining a first number of bits for a frame to achieve a target bit rate according to a first procedure that produces values for a plurality of parameters comprising a number of header bits, a number of run-level pairs and a number of DCT bits;

determining a second number of bits for the frame, wherein the determination is based on the plurality of parameters; and

allocating the second number of bits to the frame.

3. The method of claim 2 , wherein determining the first number of bits for the frame is a first pass and determining the second number of bits for the frame is a second pass.

4. The method of claim 2 , wherein the target bit rate is determined by a bit rate consumed in a previous frame.

5. The method of claim 2 , wherein the parameters further comprise the number of header bits, the number of motion vector bits, the number of run-level pairs, and the number of DCT bits.

6. The method of claim 5 , wherein the first procedure determines the number of run-level pairs as a function of a quantization factor, Q.

7. The method of claim 6 , wherein dependence on Q is determined by fitting a non-linear curve through several observations.

8. The method of claim 6 , wherein dependence on Q is determined by determining the number of run-level pairs for each value of Q.

9. The method of claim 5 , wherein the second pass matches the number of DCT bits.
