Abstract

PROBLEM TO BE SOLVED: To provide a program chart display device and method for quickly retrieving a program desired by a viewer from among 100 or more digital satellite broadcasting channels. SOLUTION: A channel which is actually frequency viewed by a user is monitored by a CPU incorporated in a tuner, and when the pertinent channel is viewed continuously in (n) minutes or more (a step 101), it is registered and displayed in a 'user program charf' as a channel which is the most frequently viewed by the user (steps 102 and 103). When the priority order of the registered (m) channels is decided, and the registration of the (m+1)th information is necessitated, a channel whose priority order is the lowest among the already registered channels is reduced, and the (m+1)th channel is newly registered as a channel whose priority order is the highest (steps 105, 106).

Description of the Related Art Satellite digital broadcasting has more than 100 channels of video and audio program data, so it takes a long time for the viewer to search for a program on which channel. The program guide data is multiplexed with the program data and transmitted as service information for causing the program guide to be searched in a short time.

[0003] At present, satellite digital broadcasting can be easily performed in newspaper columns or commercially available terrestrial television program information magazines, such as terrestrial television broadcasting signals in the VHF and UHF bands that are generally broadcast. Can not get the program information. Instead, the tuner for satellite digital broadcast reception receives program table data multiplexed and transmitted between program data as described above and processes the program guide data as shown in FIGS. The OSD is displayed and guided like a digital satellite tuner for PerfecTV currently on the market. FIG. 12 shows a Panasonic digital satellite tuner (model TU-D).
FIG. 13 is an excerpt from page 32 of the instruction manual of the digital satellite tuner (model CSR-P1) of Toshiba Corporation.

[0004]

However, the conventional program guide display device which displays program guide information as shown in FIGS. 12 and 13 can display less than 10 channels at a time. However, there are more than 100 digital satellite broadcast channels such as Perfect TV, and it is expected that the number will increase in the future. In such a situation, even if it is possible to search for a program of interest in the air currently being broadcast or not, even if it is possible to display 10 channels at a time, if the program table is not scrolled 9 times, the program is broadcast at the same time. I can't see a list of all the programs that are running.

Therefore, in the above-mentioned conventional program display device,
It has a function of "pre-registering programs frequently watched by the user" or a function of "skip channels that are not viewed" as in ordinary television receivers. , Or a function for displaying only a program other than the program skipped by the user.

However, the above-mentioned operation of "pre-registering programs frequently watched by the user" must be performed by the user, and the operation is complicated (for example, even if the present inventor registers for 20 channels, it takes one hour). It took about)

[0007] The present invention has been made in view of the above points,
It is an object of the present invention to provide a program guide display apparatus and method capable of quickly searching for a program desired by a viewer from digital satellite broadcast channels having 100 or more channels.

Further, in order to achieve the above object, the method of the present invention stores a user program table in which a predetermined number of channel numbers to be viewed are displayed in a list based on program table data separated from a satellite digital broadcast signal. While displaying it on the display device, only when it is determined that the user has watched the program of the satellite digital broadcast signal of the same channel for a predetermined time or more, it is detected whether or not there is an unregistered area in the user program table,
When it is determined that there is an unregistered area, at least a channel number is registered in the unregistered area from program guide data separated from a satellite digital broadcast signal of a channel viewed for a predetermined time or more.

[0010] In the apparatus and method of the present invention, the corresponding channel of the program to be viewed continuously for a predetermined time or more is automatically registered in the user program table and the user program table is displayed. Without registering programs that you skip or watch frequently using your favorite channels,
It is possible to display only the program guide of the channel frequently viewed by the user.

Further, in order to achieve the above object, the apparatus of the present invention, based on program guide data separated from a satellite digital broadcast signal, has a predetermined number of viewing channel numbers, and a priority order and viewing total number corresponding to each channel number.

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a system configuration diagram of an embodiment of a program display device according to the present invention, and FIG. 2 is a block diagram of an example of a satellite digital tuner as a main part of FIG.
In this program display device, a satellite digital tuner 1 is connected to a satellite dish 2 and a television receiver 3 as an example of a display device, and a satellite digital broadcast signal received by the satellite dish 2 is transmitted by the satellite digital tuner 1. A desired channel is selected and decoded, and the obtained video / audio signal is displayed on the television receiver 3, and the program guide data is separated and processed from the satellite digital broadcast signal, and the program guide is displayed on the television receiver 3. Is displayed.

The remote controller 4 is a well-known controller for remotely instructing the satellite digital tuner 1 to turn on / off the power, set a channel to be selected, control volume, and perform various other operations. Although each component of the system configuration has been conventionally known, this embodiment is characterized by the manner in which the satellite digital tuner 1 displays a program guide on the television receiver 3.

The satellite digital tuner 1 is, for example, shown in FIG.
As shown in the block diagram of FIG.
The PSK unit 14, the transport stream demultiplexer 16, the MPEG2 AV decoder 18, the video encoder 20 and the audio encoder 22 are connected to a read only memory (ROM) 25 and a random access memory (RAM) 26 via a CPU bus 27. Connected to the CPU 28.

In FIG. 2, a satellite digital broadcast signal 11 received by a satellite dish 2 is input to a tuner unit 12, and a specific frequency band corresponding to channel selection information data from a central processing unit (CPU) 28 is transmitted. Data 13
And QPSK demodulated by the QPSK unit 14 to generate a transport stream 15,
Input to the transport stream demultiplexer 16.

The above-mentioned transport stream 15 is
DVB standard "ETS 300 468" (Europian Telecommunicati
on Standard) and the MPEG2 standard “ISO / IEC JTC1 / SC29 / WG
11 N0801 ”(ISO IEC 13818-1) and the like, one transport stream is 188 bytes, and as shown in FIG.
3 and FIG. 3 (b).
As shown in the figure, the ID 31 and the stream management table 32
And the program guide data 34 are combined in time series.

The transport stream demultiplexer 16 receives information such as the program data 33, stream management table 32, and program guide data 34 of some of the above channels in a time-division manner. Only the program data of the designated channel is cut out, and the separated program data 17 shown in FIG.
Input to the EG2AV decoder 18. The MPEG2AV decoder 18 decodes audio and image data, supplies image data 19 to a video encoder 20, and inputs audio data 21 to an audio encoder 22.

The video encoder 20 encodes the input image data and outputs a video signal 23. The audio encoder 22 encodes the input audio data and outputs an audio signal 24. The video signal 23 and the audio signal 24 are input to an AV terminal or the like of the television receiver 3 to be displayed as an image and output as audio.

Next, the transport stream demultiplexer 16 will be further described. The transport stream demultiplexer 16 shown in FIG. 3A defined by the DVB standard to identify the contents from the input transport stream is used. , (B), and information such as a table 32 for managing stream data transmitted subsequently, program data 33, and program table data 34. The program table data 34 includes a program name 41, a program start time 42, a program end time 43, and a channel number 4 for broadcasting the program, as shown in FIG.
4. The genre major category name 45 to which the program belongs, the genre minor category name 46 to which the program belongs, and the like are data included in a typical program table.

The program table data 34 includes a lot of information in addition to the information required in the present embodiment. The CPU 28 in the present embodiment selects from FIG.
Is created and stored in the RAM 26 of FIG. When it is necessary to display a channel, a program name, or the like, the CPU 28 converts the program into a format that can be displayed based on the program read from the ROM 25, and outputs the format to the video encoder 20 via the CPU bus 27. In addition to displaying a normal program input from the input image data 19, a program table as shown in FIG. 9 is displayed using an OSD or the like.

Finally, in this embodiment, a user program table shown in FIG. 6 is created. When the user watches the same program for a certain period of time or more, the currently-viewed channel is registered instead of the oldest data in the user program table of FIG. As shown in FIG. 7, there is also a different type of "user program table" for registering the channels viewed for the longest time in total. Those with a higher priority number have a lower priority.

Next, the operation of the first embodiment of the present invention will be described. FIG. 5 shows a flowchart of the first embodiment of the present invention. In this embodiment, the number of channels to be registered is five, but the number of channels to be registered is variable depending on system settings, RAM capacity, and the like. (Initialization of user program guide) As an initialization value of the user program guide, all are unregistered. A method of temporarily storing a representative program in advance and shipping it, or having the user input a favorite genre (sports or the like) and storing a representative channel in the genre can be considered. (Registration and Deletion of User Program Guide) In this embodiment, first, the CPU 28 monitors whether the user has watched a certain channel for n minutes or more (step 10 in FIG. 5).
1). Here, the value of “n minutes” may be input by the user, or may be determined in advance to be 30 minutes when the system is shipped. The CPU 28 monitors whether or not the same channel has been viewed for n minutes or more.
By running a program that monitors every other minute using the timer 28 and an internal or external timer and continues monitoring until the time reaches 30 minutes, it is easy to do so, so a detailed description is omitted here. .

Subsequently, when it is determined that the user has watched a certain channel for at least n minutes, it is determined whether or not there is an unregistered area in the user program table (step 102 in FIG. 5).
When it is determined that the viewing time is less than n minutes, this processing ends without doing anything. In order to determine whether or not it is unregistered, it is determined based on a channel number that does not exist at present or in the future. If it is determined in step 102 that there is an unregistered area in the user program table, the channel of the program currently being watched is set in the unregistered area (step 10 in FIG. 5).
3). As a result, the user program table shown in FIG.
For example, when the channel number which is being watched for n minutes or more is 201, “201” is written in the channel number column of the unregistered area as shown in FIG.

On the other hand, if there is no unregistered area in the user program guide, it is determined whether or not the same channel is registered in the user program guide (step 104 in FIG. 5). If not registered, the program with the lowest priority is deleted, and the channel of the program currently being watched is entered (step 105 in FIG. 5). For example, when the user program table is as shown in FIG. 6C, 300 channels have the fifth priority and the lowest priority, so if the currently watched channel is 201 channel, As shown in FIG. 6D, 300 channels are deleted and 201 channels are registered.

Finally, in step 106, the priority of the currently viewed channel is set to 1, and the priorities of the other channels are reduced by one (step 106 in FIG. 5).
As a result, when the user program table is as shown in FIG. 6D, as shown in FIG. 6E, the priority of the 201 channel is set to 1, and the 205 , The priority of 200 channels whose priority is 2 is 3, the priority of 323 channels whose priority is 3 is 4, and the priority of 411 channels whose priority is 4 is 5 To each one. (Program display using user program table) The user program table is shown in FIG.
It is assumed that five channels are stored in the channel number column as shown in FIG. At this time, when the user selects the function of the program guide using the user program guide, the program guide is displayed with respect to the current time of each channel or the time designated by the user. The program broadcast start time 42 in FIG. 4 is prepared for each channel, the program being broadcast at the time designated to display the program table for each of the five channel numbers registered in the user program table.
And the program end time 43. The retrieved channel number 44, program name 41, genre sub-category name 46, start time 42, and end time 43 are displayed in a list as shown in FIG. (Manual update of the user program table) If the user program table is simply updated automatically to view more programs than the user program table, the channels are frequently switched or, conversely, the viewing is not performed. There is a point that it is difficult to register the channel of the program you want to use. In some cases, the user is watching the channel that he / she is currently watching for n minutes or more, but does not want to be registered in the user program table.
Therefore, a user program table registration key, a user program table delete key, etc. are provided on the remote controller 4 or the like in FIG. Register or delete. (Prohibition of registration of user program guide and fixed registration to user program guide) Some users watch a certain channel for a long time, but this is a channel that does not have to be registered in the user program guide. There is also. For such a program, a prohibited channel table described in the user program table is prepared as shown in FIG. I will not do it.

Conversely, if the channel is not watched for n minutes or more, but the channel is frequently viewed every day, the channel is fixedly registered in the user program table regardless of whether the channel has been viewed for n minutes or more. A method is also conceivable. Therefore, FIG.
As shown in FIG. 11, a field for registering a fixed flag is further provided in the user program table, and when the fixed flag is registered as 1, it is not deleted from the user program table. Also,
In FIG. 11, the channels for which the fixed flag is 1 are excluded from the targets for determining the channel priority. Therefore, in the channel in which the fixed flag is 1, the part of the priority number may be an indefinite value.

As described above, in the first embodiment, the channel that the user actually views well is set to the CP with the built-in tuner.
If the user watches the channel for more than n minutes after monitoring with U, the user automatically registers and displays it in the “user program guide” as the channel most frequently viewed by the user. It is possible to quickly search for the channel of the program desired by the user from the above-mentioned satellite digital broadcast channels.

When it is necessary to determine the priority of the m registered channels and to register the (m + 1) th information, the channel with the lowest priority among the already registered channels is deleted. Thus, since the (m + 1) th channel is newly registered as the channel with the highest priority, it is not necessary for the user to perform a channel skip operation or a registration operation of a program that the user frequently views.

Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 8 shows a flowchart of the second embodiment of the present invention. This embodiment and the first
The difference from the second embodiment is that the processing step 101 of the first embodiment is different from the processing step 201 of the second embodiment.
And the processing step 106 of the first embodiment is different from the processing step 206 of the second embodiment.
And 207. In the first embodiment, channels registered in the user program table of FIG. 6 are switched by triggering viewing for n minutes or more, but in the second embodiment, the total viewing time is equal to the current viewing time. When the time exceeds the time registered in the user program table of FIG. 7, the user program is registered.

That is, first, the total viewing time when the user watches a certain channel is larger than the total viewing time 20.5 hours of the lowest priority channel 5 registered in the current user program table of FIG. 7 ( Long) (step 201 in FIG. 8). If the total viewing time is shorter than 20.5 hours, this process is terminated without any processing. Only when the total viewing time is longer than 20.5 hours, it is determined whether or not there is an unregistered area in the user program table (FIG. 8). Step 202). In order to determine whether or not it is unregistered, it is determined based on a channel number that does not exist at present or in the future.

If it is determined in step 202 that there is an unregistered area in the user program table, the channel and date of the program currently being watched are put in the unregistered area (step 203 in FIG. 8). On the other hand, if there is no unregistered area in the user program guide in step 202, it is determined whether the same channel is registered in the user program guide (step 2 in FIG. 8).
04) If it has been registered, the program jumps to step 206 described later. If it has not been registered, the program with the lowest priority is deleted, and the channel and date of the program currently being watched are entered (step 205 in FIG. 8). ).

After the processing of step 203 or 205 is completed, or when it is determined in step 204 that the same channel is not registered in the user program guide, the total viewing time is updated (step 206 in FIG. 8). Priorities are assigned in ascending order of the total viewing time (step 207 in FIG. 8).

As described above, in this embodiment, the channel that the user actually views well is assigned to the CPU with the built-in tuner.
, The total viewing time is constantly updated, and the channel most frequently viewed by the user is automatically registered and displayed in the "user program table". The user can quickly search for the channel of the program desired by the user from the channel. In addition, priorities are set in the order of total viewing time so that the channel of the program watched the longest is ranked as priority 1. Therefore, troublesome channel skip operations and registration operations of frequently viewed programs are unnecessary. Can be.

The present invention is not limited to the above embodiment. For example, the present invention has a user program table entry prohibited channel table in which a user can input an arbitrary channel number. Steps 203 and 205
Even if the registration condition is satisfied, registration in the user program table is prohibited, and the user program table has a registerable field of a fixed flag as shown in FIG. It is also possible to apply to the second embodiment that the channel number in which the fixed flag is registered is not deleted from the user program table and is excluded from the target for determining the priority of the channel.

[0037]

As described above, according to the present invention,
The channel that the user actually watches often is monitored by the built-in CPU of the tuner, and the user views the program on the same channel for a predetermined time or when the total viewing time exceeds the time registered in the current user program table. The registration in the program guide is updated, and the channel most frequently viewed by the user is automatically registered and displayed in the user program guide, so that the user can select from more than 100 satellite digital broadcast channels. Quickly search for program channels.

Further, according to the present invention, when it is necessary to determine the priority order of the m registered channels and to register the (m + 1) th information, the priority order of the already registered channels is the highest. By deleting the channel with the lowest priority and newly registering the (m + 1) th channel as the channel with the highest priority, the user does not need to perform the channel skip operation or the operation of registering the program that he often watches. Operability can be improved in comparison.
