Appeal No. 1996-4091
Application 08/167,394
Upon our review of the specification, we note that
beginning on page 7 Appellants disclose that the HD macroblock
information comprises mode information for each group of four
"co-sited" HD macroblocks and provides the mode information to
the mode selection processor 50. The mode information includes
the type of prediction, quantizer scale information, residual
coefficient data, and motion information. Appellants further
disclose that the relationship between the co-sited HD
macroblocks and the SD macroblock is shown in Figure 2. The
relationship between each SD macroblock located at the position
(x,y) within the SD picture, corresponds to the portion of the HD
picture (of size Sx, Sy) located at position (X,Y) within the
HD picture and can be expressed by the equation X = R * x,
Y = R * y, and Sx = Sy = 16 * 4, where R equals a scale factor
for each dimension (x and y).
Appellants further disclose on page 8 of the
specification that the HD decoder 10 provides a number of bits
used to code each respective macroblock, the quantizer
information for each macroblock, and the motion vector
information for each macroblock. Also, the decoder 10 provides
