Application No. 09/126,171
OPINION
With regard to independent claims 1, 9 and 15, the examiner contends that
Hoogenboom discloses a decoding process, in Figure 2,
to decode data in a frame order with display of the data in a field
order in a first mode of operation to decode the frame, wherein the
decoding of half the B-frame in a frame order that involves the
processing of one-half of field one of the B-Frame and one-half
of field two of the B-frame. One-half of the first field is equivalent
to one quarter of the whole frame (col. 9, lines 23-38), and second
mode of operation in which two consecutive fields, where the display
of the first field of each B-frame would commence before that field
has been entirely decoded. Thus, it is possible to write into the buffer
lines vacated by display of the first half of the first B-frame field, when
decoding the second half of that field (col. 8, lines 32-39; fig. 4).
Hoogenboom further suggests the decoder to decode two consecutive
field pictures, wherein a frame a first field is decoded and displayed and
a second field is decoded and displayed (col. 9, lines 39-50) (answer-page 3).
The examiner further notes, with regard to independent claims 14 and 19,
Hoogenboom further discloses DRAM mapping for a digital video
decompression processor (fig. 1) for decompressing a digital signal
as MPEG-2 standard, including a memory DRAM (fig. 2) for storing
a plurality of anchor frames (col. 7, lines 44 through col. 8, lines 1-39),
and the decoder (48 of fig. 1) for decoding intermediate frames,
including buffer means (30 of fig. 1) for holding intermediate frame
data for display (col. 6, lines 43-57), wherein the buffer means for
distributing incoming data to any available memory location in
buffer, the address of the memory location being stored (col. 6, line 43
through col. 7, lines 1-25). See also col. 3, line 31 through col. 5,
lines 1-21. (answer-page 4).
The examiner’s analysis finds that Hoogenboom does not specifically disclose a
single frame being decoded twice, as specified in claims 1, 9 and 15, and does not
disclose a pointer table as part of the buffer, as in claims 14 and 19.
