Description

  The present invention relates to a digital broadcast receiving apparatus that receives digital broadcasts that have been rapidly increasing in recent years.

  In recent years, digital broadcasting has increased rapidly, and terrestrial broadcasting has also started to be digitized. The function of the digital broadcast receiver is to demodulate the encoded video / audio signal by the digital tuner, perform the MPEG2 decoding process, and display it on the display as the video signal / audio signal. There are functions such as electronic program guide and JPEG display.

  Among them, the electronic program guide is configured to display various types of display methods in addition to displaying time on the vertical axis and programs on the horizontal axis. There is also a method of watermarking and displaying the back image (see, for example, Patent Document 1).

  Prior art will be described with reference to the drawings. FIG. 4 is an example of an electronic program guide displayed by conventional television broadcasting. 1 is a program channel and logo. 2 indicates the time. 3 is a program title. Reference numeral 4 denotes bitmap data as a background. Reference numeral 6 denotes an area in which commercial (advertisement) data is displayed. 7 is an image of the selected channel.

  When a key of the electronic program guide is pressed with a remote controller (not shown), a horizontal axis channel, logo 1, time 2, program title 3, and background bitmap data 4 are displayed based on the arrangement position data. The background of the electronic program guide is mostly hidden by the data of the entire screen, so there is a case where it is partially divided and displayed because there is no data to store.

In addition, the commercial data 6 of the business that sends the electronic program guide may be displayed separately. In addition, the video 7 of the selected channel may be displayed. In such an electronic program guide, the time column, channel column, and program content column may change with time, but other designs are always constant.
Japanese Patent Laid-Open No. 11-234585

  Thus, in an electronic program guide that displays time on the vertical axis and channels on the horizontal axis, when there is no composition with the video of the program being viewed, for example, when watching television at midnight, in the electronic program guide , Like the newspaper, sometimes the color of the time column is changed, but the design of the entire electronic program guide can not feel the viewing time zone, only a single image display, even if time It does not change and gives the viewer the impression of a very monotonous background.

  In order to solve the above problems, the digital broadcast receiving apparatus of the present invention has a program content, a channel, and a time column in an electronic program guide, and one screen or a plurality of bits constituting a background other than the latte column. Time information is extracted from the TOT information sent from the broadcast, and the background design is changed when the electronic program guide is drawn based on the time. With the above configuration, the background of the electronic program guide can be changed according to the viewing time or the received information of the electronic program guide.

  According to the present invention, the background of the electronic program guide can be changed according to the viewing time or the received data information, the atmosphere of the viewing time of the viewer can be given, and the program broadcast The time zone that is running is immediately known and the effect is great.

  In addition, by using the display relating to the data information as a background, the viewer can obtain other information along with the program information by visually recognizing the change of the background from the background.

  The present invention relates to a digital broadcast receiving apparatus such as a television receiver that changes the background of an electronic program guide, and a specific configuration example thereof will be described below with reference to the drawings.

(Embodiment 1)
FIG. 1 is a diagram illustrating a configuration of a receiving unit of a television receiver that receives a digital broadcast and a part of a signal flow. Reference numeral 8 denotes a section filter unit. Reference numeral 10 denotes a CPU. Reference numeral 11 denotes a transport decoding unit. Reference numeral 12 denotes a graphics drawing unit. Reference numeral 13 denotes an image display unit. Reference numeral 14 denotes an MPEG decoding unit. Reference numeral 15 denotes a work memory. Reference numeral 16 denotes a flash memory. Reference numeral 17 denotes a receiving unit.

  FIG. 2 is a display example of the electronic program guide of the present invention. 1 is a program channel and logo. 2 is a time column, and a column is created every hour. Reference numeral 3 denotes a program title column, which is provided at the intersection of the channel column and the time column. Reference numeral 5 denotes the background of the electronic program guide, which is second bitmap data. Reference numeral 6 denotes an area in which commercial data is displayed, or an area in which an image of a channel selected for commercial data is displayed.

  FIG. 3 is a diagram for explaining the operation of the television receiver of this embodiment.

  Next, specific operations of the present embodiment will be described with reference to these drawings. The front end unit 7, the transport decoding unit 11 having the section filter unit 8, the CPU 10, the MPEG decoding unit 14, the work memory 15, and the receiving unit 17 having the flash memory 16 and the like are turned on (step 1). Thereafter, a transport stream is input from a radio wave broadcast on BS digital broadcasting or terrestrial digital broadcasting to the transport decoding unit 11 through the front end unit 7 of the receiver (step 2). The voice data and other SI information such as data broadcast are separated, that is, filtered (step 3).

  The SI information is stored in the work memory 15 (step 4), and time offset table (Time offset table, hereinafter referred to as TOT) information transmitted about once every about 5 seconds through the transport decoding unit 11 and software, The SI information stored in the work memory 15 is taken out, and the time information is taken out from the TOT information (step 6).

  TOT information is transmitted in a transport stream packet having a PID value of 0x0014 with a JST time and date having a fixed data structure. The number of bits is 112 bits including CRC. Depending on the broadcasting format, time information may be extracted from a time and data table (Time and date table, 64 bits, hereinafter referred to as TDT) including only JST time and date information.

  On the other hand, when the program guide key or the like on the remote control of the receiving device is pressed (step 5), the CPU 10 displays the horizontal axis, logo 1, time 2, and program title 3 based on the program arrangement position data. . Furthermore, from the SI information to the program content necessary for the electronic program guide and the broadcast time information, from the bitmap data already transferred to the work memory 15 based on the current time of the TOT information, from 18:00 to 20:00 Between 4 o'clock and 6 o'clock, for example, the bitmap drawing data of twilight design (step 8), and from 20:00 to 4 o'clock the next day, for example, the second bitmap data of the night design is rendered as a graphics drawing unit ( Step 9), output.

  With the above configuration, the background of the electronic program guide can be changed according to the viewing time, the atmosphere of the viewing time of the viewer can be given, and the time zone when the program is broadcasted I understand immediately.

(Embodiment 2)
FIG. 3 shows the state of the screen by the digital broadcast receiving apparatus in the second embodiment of the present invention. In the present embodiment, (Embodiment 1) exchanges bitmap data based on time information, but based on other information in the data broadcast, The background is converted.

  In FIG. 1, the CPU 10 selects information related to “weather forecast” from SI information that is data information stored in the work memory 15. For example, if the weather forecast for the next day in the viewer's reception area is “cloudy”, the bitmap data 5 related to the information is selected from the flash memory 16 and displayed on the background of the electronic program guide. In this case, in addition to bitmap data of a design such as “cloudy”, “sunny”, “rain”, character information may be displayed together. For example, the time, area, and the like that are the target of the prediction of the bitmap data being displayed may be displayed.

  Furthermore, it is possible to make it easier for the viewer to convey information by outputting sound together with the background screen according to the data information. Further, the background may be divided into a plurality of screens, and bitmaps related to various information may be displayed, and the bitmaps may be changed according to time.

  With the above configuration, in the present embodiment, the background screen of the electronic program guide can be changed based on the data information reflected in the electronic program guide in the television broadcast. Since other information can be visually recognized or confirmed by voice while looking at the table, the viewer can obtain a plurality of information according to the change of time without particularly switching the screen.

  The digital broadcast receiver according to the present invention can display information other than the electronic program information on the background of the electronic program guide, and thus can display information other than the program information. It is useful as a receiving device that can output to various display devices such as display devices for mobile phones and mobile terminal display devices.
