Reexamination Control No. 90/005,742
Patent 5,253,341
1 Id. at col. 10, ll. 3-17. Referring to Figure 6, which depicts a preferred embodiment of a
2 receiving system 200 (col. 17, ll. 67-68), transceiver 201 automatically receives the information
3 from the transmitter 122 as compressed formatted data blocks, while format converter 202
4 converts the compressed formatted data blocks into a format suitable for storage in storage
5 device 203. Id. at col. 18, ll. 6-21. When playback is requested, the compressed formatted data
6 blocks are sent to a data formatter 204, which processes the compressed formatted data blocks
7 and separates audio and video information. Id. at col. 18, ll. 26. During playback, the separated
8 audio and video information are respectively decompressed by audio decompressor 209 and
9 video decompressor 208 before being applied to digital and analog audio and video output
10 terminals 211-14. Id. at col. 18, ll.27-38.
11 (3) Comparing claim 11 to Yurt
12
13 The examiner contends, and Dr. Koopman does not deny, that Yurt discloses all of the
14 claimed subject matter except for the requirement that the query be transmitted from the remote
15 query and data retrieval means to the remote host processor "via a concentrator means." 3d
16 Action at 86, para. 19; Final Action at 243, para. 19. Specifically, he reads the recited end user
17 means and remote query and date retrieval means on the reception system 200 depicted in
18 Figure 6, the recited remote host on the transmission system 100 depicted in Figures 2a and 2b,
19 and the recited input/output means on element 207 in Figure 6. Decompression of the video
20 information, which has been compressed in the transmission system using two compression
21 techniques, is effected by decompression element 208 in Figure 6, which outputs digital and
22 analog video signals on terminals 211 and 213. The decompressed video information can be
