Abstract

PROBLEM TO BE SOLVED: To provide a reception program display system capable of varying the height of a display frame matching the height of a page number. SOLUTION: A program analysis program 209 fetches data decoded in a decoder part 204 and performs a program reconstitution processing for rearranging the data for respective service identification, program numbers and page numbers. When a program is selected in an input device, a program display program 208 fetches the data pertinent to the selected program from the program analysis program 209, changes the display frame when the total of the height of the acquired total page number and the height of the display frame displayed at present are different and simultaneously displays the data of all the pages of the reception program at a display device.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a received program display system, and more particularly to a received program display system that receives broadcast data such as FM multiplex broadcast and displays the received data on a liquid crystal display or a display of a personal computer. .

[0002]

2. Description of the Related Art At present, an FM multiplex receiver has a limited number of pages (one page or two pages) on a limited display screen of a display device.
Page), or when displayed on a wide display screen such as a personal computer display, only one page or a plurality of pages are displayed.

[0003]

The total number of pages of each program transmitted from a broadcasting station differs depending on the program. When the number of pages that can be displayed is limited by a display device, the total number of pages of the selected program is displayed. There is a disadvantage that not all pages can be displayed at one time depending on the case.

[0004] Therefore, a main object of the present invention is to provide a received program display system capable of viewing all pages of a selected program at a time.

[0005]

SUMMARY OF THE INVENTION According to the present invention, in a received program display system for receiving broadcast data and displaying the data on a display device, the display frame is changed according to the total number of pages of the selected program. And display control means for displaying data of all pages of the received program on a display device.

[0006]

FIG. 1 is a diagram showing an embodiment of the present invention. In FIG. 1, a personal computer 1
01 is provided with a display device 102 such as a keyboard and a mouse, and an input device 103. A broadcast data receiving device 104 for FM multiplex broadcasting or the like is attached to a side surface of the personal computer 101. In this example, PCMC
As a PC card type receiver having an I / F of 1A, the receiver is inserted into a PC card slot of the personal computer 101 and can display received data being broadcast.

FIG. 2 is a block diagram showing an embodiment of the present invention. In FIG. 2, F
Radio waves of M broadcast are received and provided to FM tuner 202. The FM broadcast is demodulated by the FM tuner 202, and the audio signal is amplified and provided to the speaker 203, and the audio is output. The decoder unit 204 separates the FM multiplexed data and the audio data based on the output of the FM tuner 202, and demodulates the FM multiplexed data. Control unit 2
05 controls the receiving side of the interface (I / F) 206 and controls the tuner 202. The interface 206 is a PCMA1A / IEIDA, I for exchanging data between the personal computer and the receiver.
Interfaces such as an SA bus, a serial port, and a PCI bus. A device driver 207 is connected to the interface 206 on the personal computer side.

The device driver 207 controls a personal computer for exchanging data with the interface 206. The program display program 208 calls the switching of the frequency to the control unit 205, and controls the display of the received data of the program. The program analysis program 209 takes in the data decoded by the decoder unit 204 via the control unit 205, the interface 206, and the device driver 207, and rearranges the data for each program group (service identification, program number). Perform The configuration of each program has a hierarchical structure in which a table of contents program (a program displaying data of a table of contents items) is the highest layer. When the program display program 208 specifies the selection control (service identification, program number, page number of each layer), the data corresponding to the selection control is returned to the program display program 208.

FIG. 3 is a view showing a display example of received data. In particular, FIG. 3A shows that the total number of pages of the currently selected program (for example, service identification 2 and program number 13) is 6 pages. (B) shows a state in which the received data of a total of two pages of the second page and the third page are displayed, and (b) shows a state in which the received data of a total number of three pages are displayed all at once. In FIG. 3A, reference numeral 301 denotes a first page header text (one line), and reference numeral 302 denotes a first page text (2 lines).
), And 303 is the text of the second page (two lines). Note that the header text of the second page is not displayed. FIG.
The program displayed in (a) is a program at a level immediately below the table of contents program (the highest level). FIG. 3B shows a table of contents program.

The display shown in FIG. 3A is realized by the display device 102 shown in FIG. When this program is selected, the program display program 208 includes selection control (service identification 2, program number 0, page number 1) for returning to the program at the next higher level when the screen of FIG. 3A is displayed. ) Is registered,
Selection control (service identification 2, program number 16, page number 1) going to a layer lower than the current layer is registered.

When a selection is made to return to the hierarchy one level higher than the input device 103, the program display program 208 sends the service identification 2, the program number 0, and the page number 1, which are selection controls for returning to the hierarchy one higher, to the program analysis program 209. And the program analysis program 209 returns to the program display program 208 the total number of pages of the specified program, the selection control data, and the data of the selected page. Program display program 208
Compares the total height of the total number of acquired pages 3 with the currently displayed display frame, and if the values do not match, changes the size of the display frame to a size capable of displaying all pages. The selected data is displayed as it is without changing. In the example shown in FIG. 3B, the display frame is changed so that three pages can be displayed, and after the display frame is changed, the data received from the program display program 208 is replaced with the header sentence 304, 1 of the first page. The text 305 of the page, the text 306 of the second page, and the text 307 of the third page are displayed on the display device 102 in this order, and the screen shown in FIG. 3B is obtained.

[0012]

As described above, according to the present invention, by changing the display frame according to the total number of pages of the selected program, all pages can be displayed at once. Moreover, since it is not necessary to display a page having no received data larger than the total number of pages, there is no need to perform extra display. For example, when a page is displayed on a display screen such as a display device of a display of a personal computer,
The screen can be used effectively.
