Method and apparatus for performing real-time data encoding

The method of clam 7, further comprising quantizing the transformed half of the modified subsampled frames, while the second half of the modified frame is not quantized.

9 The method of claim 7, wherein the first half of the modified subsampled frame contains low-frequency components of the frame, while the second half of the modified frame contains all zeroes.

The method of claim 9, wherein the first half of the modified frame is the right-half of the frame, and the second half is the left-half of the frame.

An apparatus comprising:

• a motion estimation circuit to receive one or more frames of data, filter said received frames of data, horizontally subsample said filtered frames of data by a scaling factor and to modify the subsampled frames of data to resemble full-resolution frames of data.

The apparatus of 17, wherein the motion estimation circuit further comprises a qauntizer circuit to quantize the transformed half of the modified subsampled frames, while the second half of the modified frames are not quantized.

A storage medium comprising a plurality of executable instructions which, when executed by a processor, cause the processor to implement a data encoding function to receive one or more frames of data, low pass filter the received frames, horizontally subsample the filtered frames by a scaling factor and modify the subsampled frames to create full frames of data.
