DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0053] A program list display system according to the preferred embodiments of the present invention is described below. FIG. 1 is a construction diagram showing the construction of a digital television broadcast receiving set including a program list display system according to an embodiment.
[0054] Tuner 1 selectively receives a broadcast wave desired by a user from input radio waves received through an antenna and amplifies it, comprising a high-frequency amplifier circuit, a tuning circuit and the like. A demodulator 2 demodulates the received wave selectively received by the tuner 1 and outputs digital signals, comprising an OFDM demodulating circuit for OFDM demodulation of the OFDM-modulated broadcast wave, and the like in digital television broadcasting.
[0055] A decoder 3 decodes the OFDM-demodulated digital signals, or returns the digital signals on which transmission error prevention, compression, joining and the like were conducted before modulation in a broadcast station to their original digital signals, comprising a logical circuit, a digital signal processor and the like. And the digital signals decoded by the decoder 3 are output as sound data, video data, and processing and control data of various kinds each to a sound decoder 4, a video decoder 5, and a microcomputer (a bus line for data transmission). Here, EPG data (program data) contained in broadcast signals is output to the bus line B for data transmission.
[0056] The sound decoder 4 decodes the sound data from the decoder 3, or conducts digital processing such as data error decompression and expanding as opposed to the transmission error prevention, compression and the like which were conducted on the sound data so as to decompress its original sound data, comprising a logical circuit, a digital signal processor and the like. The sound signal output from the sound decoder 4 is output as a sound through a speaker 12 after digital-to-analog conversion and power amplification (not shown).
[0057] The video decoder 5 decodes the video data from the decoder 3, or conducts digital processing such as data error decompression and expanding as opposed to the transmission error prevention, compression and the like which were conducted on the video data so as to decompress its original video data, comprising a logical circuit, a digital signal processor and the like. On the video signal output from the video decoder 5, image quality processing such as brightness, contrast and hue, composing/switching processing with/to other images (an EPG etc.), and the like are conducted in a video processor 6 so as to be displayed on a display 13 comprising a liquid crystal display and the like. The video processor 6 includes a VRAM and outputs video signals to the display 13 based on data written in the VRAM. That is, by equalizing data written into the VRAM to data desired, it becomes possible to show desired images on the display 13.
[0058] It is the microcomputer that controls each kind of operation of the overall digital television broadcast receiving set, comprising a central processing unit (CPU) 10 which performs processing, a ROM 9 in which programs and various kinds of data are stored, a RAM 8 which temporarily stores various kinds of data, and the like. Here, to the RAM 8, backup power is provided even if a power switch is OFF, so as to hold data. And each component of the digital television broadcast receiving set is connected through the bus line B, so that data transmission to each other is possible.
[0059] A modem 11 is connected to the bus line B, so that the digital television broadcast receiving set enables communication with the outside such as communication with a digital television broadcast station, or connection to the Internet. For example, program data can be obtained through communication with a television broadcast station or from the contents of the Internet. Furthermore, an input/output interface (I/O) 7 is connected to the bus line B, so that connection with outer equipment is possible. For example, data of a remote control 14 using infrared rays or the like is captured so as to operate according to the data, so that a user can allow the digital television broadcast receiving set to perform desired operation by operating the remote control 14.
[0060] The display processing of a program list is described below. First, the outline of the overall display processing of an EPG is described by reference to a flow chart shown in FIG. 2. This display processing of a program list is conducted when program data is received.
[0061] In Step 1, received program data is stored in the RAM 8, and then the processing goes to Step 2. The storage of the program data into the RAM 8 in Step 1 is conducted by a system wherein only a portion different from the program data stored in the past is rewritten. This system adopted brings the program data stored in the RAM 8 up to date all the time, so that a program list is made based on the latest data. And the past data are held until an area for program data storage allocated to the RAM 8 is filled up, and then older program data is cleared so as to secure the storage area. The program data includes the program title, program contents, genre, broadcast time and the like.
[0062] In Step 2, program data at an appropriate date and time are selected and read out from the RAM 8 according to the date and time of a displayed EPG, and then the processing goes to Step 3. In Step 3, data unstored in the RAM 8, or unreceived program data, among the program data at the date and time required according to the date and time of the displayed EPG, is predicted and formed based on the past program data and the like, and it goes to Step 4. Here, the predictive formation of unreceived program data is described below with examples.
[0063] In Step 4, a program list is made based on the selected received data and the predictively formed program data, and is written into the VRAM, and then the processing is ended. The program list thus made is shown on the display 13. Though display examples of a program list are described below, the making of a program list comprises the processing wherein program slots are formed according to the time period of each program data in the displayed date and time periods and are filled with program titles, contents, marks, background images (background colors) of the corresponding programs to the program slots, the processing wherein a line, an arrow or the like is written into a desired portion of a picture after the former processing, and the like. Such processing is performed by processing the data written into the VRAM.
[0064] A display example of a program list is described below. FIG. 3 is an illustration showing a display example of a program list shown on the display 13. An in-reception channel number and its broadcast station name are shown in the top portion of the program list, while broadcast time periods are shown on the left side. Since multiple programs can be broadcast on one channel in the case of digital television broadcasting, three program columns (Services 1-3) are shown in this example. And in each program slot of each service, a program title corresponding to the program slot is shown.
[0065] Relating to details (performers or the genre) of a program, the area of its program slot is not sufficiently large to clearly show them. Therefore, they are shown on the program list at the instant when the program slot is selected and detailed display operation is conducted using the remote control 14. In this example, the program data corresponding to the 8 o'clock program slot in Service 2 has not been received yet, and the program slot is displayed differently from the other program slots. As the display methods, any of the below-described methods {circle over (1)}-{circle over (3)} can be used or these methods can be used in combination, and it is clearly shown that the program data of the program slot has not been received yet.
[0066] {circle over (1)} Program data such as a program title of an unreceived program slot is not shown and the program slot is filled in with a background color A different from that of received program slots.
[0067] {circle over (2)} A mark B showing that the program data has not been received is displayed in an unreceived program slot.
[0068] {circle over (3)} An image C of a program which is being received and displayed is shown in an unreceived program slot. In this method, it is possible to make sure the program which is being received and displayed using a real image.
[0069] Concerning the 10 o'clock program slot in Service 3 which was changed from an unreceived program slot to a received program slot because of new program data, a flashing display of its background color is conducted (the color is switched at prescribed intervals) so as to enhance the reception of the program data. In another embodiment, a method wherein the background color is changed, a method wherein a mark is displayed or the like may be adopted, besides the flashing display of the background color. Or these methods may be adopted in combination. All the cases have the effect of enhancing the reception of the program data.
[0070] Another display example of a program list is described below. FIG. 4 is an illustration showing a display example of a program list shown on the display 13. Since the outline of the program list is similar to that of the program list shown in FIG. 3, it is not described here. In this example, there is a characteristic in the display form in cases where there are different programs relating to the same event, and the backgrounds of program slots E and F for those programs are filled in with a background color A different from that of the other program slots (the slots E and F are filled in with the same color). That is, the program slots E and F are displayed so as to show that the program slots E and F are filled with programs of the same event.
[0071] In another embodiment, prescribed marks may be displayed to show that the program slots E and F are filled with programs of the same event. Or these methods may be combined. An arrow G showing that a high-school baseball game (the same event) to be broadcast at 8 o'clock in Service 3 is to be successively broadcast (what is called a relay broadcast) at 9 o'clock in Service 1 is displayed in the program list. That is, a display showing a time relationship between programs broadcasting the same event is shown in the program list. As to the program slot F at 9 o'clock in Service 1, the program data thereof has not been perfectly received, so that the program data (the program title is displayed in the program list, and detailed information is displayed by a predetermined operation) is displayed based on the program data of the program slot E whose program data has been already received, and a mark indicating that is displayed.
[0072] Here, whether the same event is broadcast or not is judged from the identity of the event information and the program titles included in the program data, or relay broadcast data (data of the source or the target of the relay), but this judgment cannot be made at the instant when there is no program data received. Therefore, a relay broadcast display of the same event is displayed from the moment when (a portion of) the program data useful for judgment is received.
[0073] A still another display example of a program list is described below. FIG. 5 is an illustration showing a display example of a program list shown on the display 13. Since the outline of the program list is similar to that of the program list shown in FIG. 3, it is not described here. This example shows a display form in cases where the broadcast time of a certain program has been changed, or a soccer game program H broadcast at 8 o'clock in Service 2 was extended till 9:30, so that the following programs, a news program and a serial drama, were shifted by 30 minutes. The program slot 1 before the change has been reduced and moved to the right portion of the display column of Service 2, and its background color has been made a display color different from that of the other program slots, so that the program slot becomes less noticeable and it can be known that the program is a program before the change. And the characters and the like have been made semitransparent, which makes it easier to distinguish the program before the change. A program slot J after the change is relatively large in the left portion of the display column of Service 2, and its background color is a display color similar to that of the program slot before the change (for example, the same color but a little dark, with heavier frame lines or the like), so that the program slot becomes noticeable and it can be easily known that the program is a program after the change through the relationship with the program before the change. Furthermore, an arrow K showing the relationship between the programs before and after the change, or an arrow K showing the broadcast time of which program is changed to what time period is displayed, so that the changes in the programs are easy to know.
[0074] A still another display example of a program list is described below. FIG. 6 is an illustration showing a display example of a program list shown on the display 13. Since the outline of the program list is similar to that of the program list shown in FIG. 3, it is not described here. This example shows a display form of a serial program wherein a continued event is broadcast in parts in point of time, for example, a regular-time news program or a serial drama broadcast at a fixed time every day, or on Monday to Friday or Saturday, or a serial drama broadcast at a fixed time on a prescribed day every week. And in another embodiment, it is also possible to apply this form of display to regular-time programs which do not broadcast a continued event but have strong relations (movies or variety programs).
[0075] In the case of a serial program broadcasting a continued event (such as the same drama), the backgrounds of the program slots L1 and L2, or M1 and M2 are filled in with a background color A (the slots L are filled in with the same color) different from that of the other program slots. That is, it is shown that the program slots L1 and L2, or M1 and M2 are serials of the same event. In another embodiment, prescribed marks may be displayed to show that the program slots L1 and L2, or M1 and M2 are serials of the same event. And an arrow N showing the successiveness of the program slots L1 and L2 is displayed in the program list. That is, a display showing a time relationship between programs broadcasting a continued event is displayed in the program list. Here, as to the program slot L2 at 8 o'clock in Service 2, its program data has not been perfectly received yet, so that the program data (the program title is shown in the program list, and detailed information is displayed by a prescribed operation) is displayed based on the program data of the program slot L1 whose program data has been already received, and a mark indicating that is displayed.
[0076] Whether they are serials or not is judged from the identity of the event information and the program titles included in the program data, or serial program data (successive period data and broadcast time data), but this judgment cannot be made at the instant when there is no program data received. Therefore, a serial program display is displayed from the moment when (a portion of) the program data useful for judgment is received.
[0077] A method for predicting and forming program data from characteristics of program schedules in serial programs or strongly related regular-time programs (movies or variety programs) in cases where the program data has not been received yet is described below. A program list is made using such predictively formed program data.
[0078] As characteristics of program schedules, till 18:00 and after 23:00 on weekdays (Mon.-Fri.), there has been a very strong tendency to broadcast a program of similar contents with the same title (hereinafter, referred to as a same title program) at the same hour (hereinafter, referred to as the A time period) every day, while between 19:00 and 23:00 on weekdays, and on Saturday and Sunday (throughout the days) (hereinafter, referred to as the B time period), there has been a very strong tendency to broadcast a same title program on the same day every week. Therefore, in this embodiment, regarding a program whose program data has not been received yet, program data of a program in the A time period is predicted using program data at the same hour on another day (such as the preceding day on weekdays), while program data of a program in the B time period is predicted using program data at the same hour on the same day of another week (such as one week ago).
[0079] The program data for such prediction is stored in the RAM 8, and freshly received program data is always written over the program data stored in the RAM 8, resulting in a high accuracy of prediction. The program data for prediction is preferably program data on the closest day in point of time to the program targeted for prediction (one day ago (later), one week ago (later)). Here, as to the A and B time periods, when users can select them by operation of the remote control 14 or the like, it becomes possible to deal with more various program schedules. In this case, the selected data is stored in the RAM 8.
[0080] As described above, using the program list display system according to the embodiments of the present invention, program data can be predicted and formed with more high accuracy by appropriate estimate, even if the program data has not been received yet, so that an appropriate program list can be displayed promptly. And a program list which enables users to easily find predicted program information, serial programs, programs having a change in the broadcast time, relay programs and the like is displayed, resulting in a useful program display for users.
