[0033]   In the receiving device 1, the composite video generation unit 5 receives the data related to the EPG input. The amount of data in the synopsis is detected for the program currently being broadcast included in 1). Specifically, it detects the number of characters in the synopsis for the program currently being broadcast. . When the receiving device 1 detects the data amount of the synopsis, it displays this synopsis. The size of the display area required for the calculation is calculated (s2). In s2, the character detected in s1 Divide the number by the number of display characters per line in the display area that displays the synopsis, Calculate the number of lines required to display the synopsis, and then calculate the number of lines according to the number of lines calculated here. Calculate the size of the streak display area. Round up after the decimal point in the calculation of s2 By doing so, the number of lines required to display the synopsis can be calculated.

[0034]   The width size (in the case of horizontal writing) of the display area that displays the synopsis is set in advance. The number of characters displayed per line is the maximum number of characters that can be displayed in this width size. (The number of display characters per line is predetermined.)

[0035]   In the receiving device 1, the number of lines calculated in s2 is less than or equal to a predetermined upper limit number of lines. It is determined whether or not (s3). If it is determined in s3 that the number of rows is less than or equal to the upper limit number of rows, in s2 The size of the synopsis display area in the height direction is set according to the calculated number of lines (s 4). In s4, when the number of rows detected in s2 is n rows which is equal to or less than the upper limit number of rows, The size in the height direction is set to the minimum size required to display n lines.

[0036]   Therefore, the smaller the number of lines in the synopsis, the higher the height of the cover area that displays the synopsis. The size of the direction is set small.

[0037]   The composite video generation unit 5 sets the display area of the synopsis to the size set in s4, Extracted from the data related to EPG in the video of the video data input from the feeder 4.

[0039]   In the display device 12, the currently selected channel is displayed as shown in FIG. The channel, program title, program broadcast time, etc. are also displayed along with the above synopsis. There is. In addition, the location bar shows how much broadcast You can easily check if is progressing.

[0040]   In this way, the size of the area for displaying the synopsis is set according to the number of lines in the synopsis. Nothing is displayed in the area where the synopsis is displayed. There is no wasted area and the synopsis is displayed at once, so The visibility of the user who confirms the stripe is not reduced.

[0041]   If it is determined in s3 that the number of lines is not less than or equal to the upper limit number of lines, the height of the synopsis display area is determined. Set the direction size to the minimum size required to display this upper limit number of rows (s 6). The receiving device 1 displays the display area of the synopsis whose size is set in s6. , Display the number of displayable characters (number of lines) (s7), and wait for a predetermined time ( s8). If it is determined that the predetermined time has elapsed in s8, the display is made in the synopsis display area. The synopsis shown is scrolled by one line and displayed (s9). It is determined whether it is completed (s10). If the display is not completed, return to s8 Repeat the above process.

[0042]   In this way, the display area that displays the synopsis is limited to the size in the height direction. Since the (maximum number of lines) is provided, the display area for displaying the synopsis is too large. No synopsis and scrolling line by line at a specified time interval to display the synopsis. Since it is shown, a special operation (scrolling operation) is required for the user to check the synopsis. There is no need to do the work. Therefore, the operability for the user is not reduced. Also, since the synopsis is displayed without reducing the font size, It does not reduce the visibility.

[0043]   In the above embodiment, the synopsis is displayed by scrolling at a predetermined time interval. However, in the synopsis display area, pages are switched at predetermined time intervals and The synopsis of the program may be displayed.

[0044]   Further, although not particularly described in the above embodiment, in the second mode, The video of the program, which is the source of the synthesized video, is (received and transmitted over time). (Depending on the issue). Further, in the second mode, the signal is received from the output unit 6. The audio signal included in the broadcast signal being output is being output.

[0045]
