4.3.1.3 Technical Details4.3.1.3.1 Functions of home storage devices for TV AnytimeHome storage is designed as a three-layer system that allows viewers to select any services they want from the given information categories. The broadcasting station transmits information and programmes to the television receivers during a fixed time (for example early morning hours when people are still asleep). The ISTV receiver selects and classifies this updating information (using its self-editing function) and stores it in its home storage. Then any information or programme which viewers like can be called up with a one-touch icon, anytime they like. This home interactive service can be used around the clock. Storage and home-delivery of information is depicted in Fig. 4.2. The following describes how the three-layer system of home storage acts: 1) Automatic Package Reception Like the home delivery of newspapers, the TV newspaper and programmes can reach viewers’ homes while they are still asleep. News items and weather forecasts are to be automatically updated at fixed intervals, using the “anytime” functions. 3) Automatic Personalized Selection Information, visual material, data on performers and other items which viewers are interested in can be automatically called up, selected and videotaped.
