Abstract

A favorites list of program channels which a cable TV user likely prefers is generated automatically from which the user may select a program channel to watch. Each program channel in the favorites list is identified based on a measure of the duration in which the program channel is continuously tuned to. In an embodiment, this measure varies nonlinearly with such a duration. The favorites list may further comprise sublists of program channels which may correspond to different periods of a day, week, etc. The favorites list may be generated from programs watched on multiple viewing devices.

k”

user-preferred program channels stored in the first and second memories;

a first channel table stored in the first memory, wherein the first channel table comprises a first list of viewed channels as selected by the first STT, wherein each viewed channel of the first list of viewed channels is associated with a first cumulative count value;

generate a common channel table from the first and second channel tables; and

send the common channel table to the first and second STTs.

wherein the first and second processing units execute instructions causing the first and second processing units to;

select from the common channel table the “

k”

program channels having the highest cumulative count values; and

update the common list of user-preferred program channels to reflect the selected “
