Development and features of a TV navigation system

A TV navigation system has been developed to make it easier for viewers to watch television in a multichannel area. It enables viewers to watch programs recommended by the system as well as to select programs using a personalized electronic program guide (EPG) and retrieve programs with a personal filter. The system combines a mechanism for recommending programs in accordance with the preferences and mood of the viewer with personalized program sorting and retrieving in an easy-to-use format. Subjective evaluation tests were held to evaluate the impressions of general viewers with regard to operating this TV navigation system and benefiting from its use. It was found that program recommendations were helpful and that the types of programs desired by a viewer and their method of selection differed according to time of day.
