Young states (at page 23 lines 2-9) that the Channel Customisation screen 116:
“allows the user to customise channels to match viewing interest, providing a compact listing as well as eliminating undesired channels during up down scanning. During schedule update, a list of all cable channels available at the subscriber’s cable (or broadcast stations for over-the-air subscribers) is also delivered to the VCR. This unabridged set of channels may be customised using screen 116.”
It goes on to explain how the user can select 12 favourite channels which are listed in the MY column 120 on the screen shown in Fig. 20. It then states (page 24 lines 6-11):
“The order of listing in the MY favourite channel column 120 is as follows:
All favourite broadcast stations will be listed first in numerical order. Next, all cable services will be listed in alphabetical order.”
The second passage (at page 24 line 34 to page 28 line 16) describes two “television schedule systems/tape controllers” 180 and 182 in which the user interface is used. Schedule system/controller 180 is shown in Fig. 22A which I reproduce below:
The figure contains a small typographical error and a small omission, both of which are obvious from reading the specification. The box below line 216 should be labelled “VBI decoder”, not “VDI decoder”, and it should be identified by numeral 222.
