Title: Program guide display method and device
Inventor: OKUBO YOKO
IPC: H04N7/173
Filed: 2000-01-11
Abstract: PROBLEM TO BE SOLVED: To provide a program guide that users can surely visually recognize even for a program of which broadcast time is short. SOLUTION: A program guide display processing section 201 is activated, a temporary storage section 212 acquires program guide information broadcast for a prescribed time zone from a program information storage section 19 to calculate a length of a broadcast time. When there exist programs whose broadcast time is less than 5 minutes, number of the programs whose broadcast time is less than 5 minutes and a total broadcast time of programs whose broadcast time is 5 minutes or over are acquired. A table stores a display size of the programs whose broadcast time is less than 5 minutes as a prescribed value.  The table stores the rest of the display size of the programs whose broadcast time is 5 minutes or over after subtracting the display size of the programs whose broadcast time is less than 5 minutes from it as a value obtained through the proportional distribution to the broadcast times. Then the processing above is executed for all channels, the table of a storage section 213 stores the execution results that are arranged in the order of program broadcast times. The program guide display processing section 201 gives manes of channels and time to the table of the storage section 213 and allows a display means 11 to display the table.
