- Program information (609) names of performers (6 10
- keys (6 1 1) keys
- the recording channel may be included in the EPG.
- EPG is also called a program guide in digital satellite broadcasting, and is used to assist users in viewing broadcast programs.
- the EPG in digital satellite broadcasting is described in detail in the Journal of the Institute of Image Information and Television Engineers, Vol. 51, No. 9, 1997, pp. 1364 (30) -1369 (35). Also, it is expected that a service for embedding and distributing EPG in the VBI area will also appear soon on terrestrial waves.
- FIG. 14 shows the structure of the channel assignment table 800.
- the channel assignment table 800 shows the channel (CH) number 801, program title 802, recording date (year 803, month 804, day 805, time 806), recording time length 8 07, viewing history 808, save mark 809, storage location (start position 810, end position 811).
- the channel number or broadcast station name of the received broadcast station may be added.
- the recording date and time indicate the date and time when the program was recorded.
- the recording time length 807 indicates the time length of recording the program. Since the user does not always record an entire program, the recording time length does not always match the broadcast time of the program.
- the viewing history 808 indicates the length of time the user has watched so far. Also, here, the user always watches the recorded program from the beginning, and only records the viewing time length.
- the save mark 809 can be marked for later viewing by the user. Conversely, if this mark is not ON ((in the figure), the system may automatically cancel the channel setting.
- the storage location indicates the location where the recorded program is actually stored. The playback program loads the recorded program from this storage location and plays it back.
- Columns 8 21 to 8 30 in the figure represent examples for each channel.
- column 8 21 indicates that the program “First Love” recorded on February 9, 1998 at 20:00 on channel number 01 is recorded for 60 minutes.
- the user has watched the same recorded program for only 20 minutes so far, and the save mark is not ⁇ N.
- a recorded program with a channel number of 0 1 to 0 3 is equivalent to a drama, and 0 2 1 to It can be seen that 0 2 2 corresponds to a movie, 0 41 to 0 42 corresponds to a sports program, 0 81 corresponds to a variety program, and 0 91 corresponds to other programs.
- the channel number 1 1 1 has the same content as the channel 0 4 1, but the channel number is assigned according to the keyword “sports competition”. Users can play sports From this point of view, the sports competition opening ceremony can be referred from both perspectives.
- FIG. 3 shows a processing flow of the channel definition program 200.
- This program is executed when the user presses the menu button 902 on the remote control and selects the CH definition menu from the displayed menu group.
- the program is executed in step 201, the current channel definition table 700 is first displayed to the user. At this time, if the user has not defined the channel definition table, such as immediately after the user purchases the device, the initial values specified by the system are displayed. The initial value should be set so as to cover as many general users as possible so that the user does not need to change it.
- FIG. 16 shows a screen example 10000 of the channel definition.
- the channel definition table shown in Fig. 13 is displayed as it is.
- the user selects each channel set using the select button 920 on the remote control.
- the selection area 1001 is highlighted according to the user's selection.
- the screen shifts to a screen for editing the channel set (step 204).
- the value of each item in the channel definition table is changed.
- the program attribute or program information is an operation method of selecting an item from candidates that can be changed (step 205).
- the changed content is immediately reflected in the channel definition table 700 and the channel definition screen 100 (step 206).
- Operation buttons are displayed at the bottom of the channel definition screen. Use the previous screen button 1 0 2 and the next screen button 1 0 3 when the channel definition table cannot be displayed on one screen. In this example, there is nothing on the previous screen, The fact that the channel set is still lined up on the surface is indicated by the button shape (hatched, solid line). Also, the end button 1004 hides the channel definition screen and returns to the original screen. Conversely, the user will repeat the channel definition until the end button is selected.
- FIG. 4 shows the flow of processing of the channel assignment program 300.
- the program is executed when recording a program.
- the program runs
- Step 301 electronic program information of the program recorded in step 302 is obtained.
- step 303 a channel set corresponding to the electronic program information is acquired by referring to the channel definition table.
- steps 305 to 309 are repeated (step 304).
- step 305 it is checked whether there is a free space in the channel set by referring to the channel assignment table. If there is a vacancy, the process proceeds to step 307 as it is, and if there is no vacancy, the channel securing program 350 is started (step 306).
- the details of the channel reservation program will be described below, but in short, it is the process of reserving channels that are deemed unnecessary for newly registered programs.
- a channel number having a free channel set is assigned to a recorded program.
- the numbers are assigned in ascending order so that the numbers are consecutive in the channel set.
- one channel number is assigned to each program, but a channel set may be used as one channel number as described above.
- a list of applicable programs display of program name, broadcast time, broadcast channel, etc.
- the display screen is divided, and each divided child is displayed.
- the program corresponding to the screen is displayed, and (3) predetermined portions such as the start portion of the program are displayed one after another.
- the information (number) related to the recorded program is stored in the corresponding channel number in the channel assignment table 800. Group title, storage location, etc.).
- step 4 the process is repeated, and if not, the program ends in step 310.
- FIG. 4 uses the concept of a channel set, it may be used without using it. For example, check if there is a free channel number for each program, and if there is a free one, assign it. Also, the channel number set may be assigned according to the program without being judged simply because it is not empty. Assignment may be made according to the "Program Information" in Fig. 13, such as "11-20CH” for "Drama” and 21-30CH for the performer Xiko Takakawa. It may also be assigned based on broadcast station, date and time, program content (keyword), etc. In addition, at this time, each channel number may be associated with each channel set. For example, a set of channels may be aligned with the last digit, or be a multiple of three. Channel numbers may not be assigned in ascending order, but may be assigned according to the program. This is true with or without the concept of channel sets. Further, the channel number may be not only a number but also other characters (words). Other characters include symbols, alphabets, etc.
- FIG. 5 shows a processing flow of the channel securing program 350.
- This program is called from the channel assignment program 300.
- a search is made from the channel assignment table for a channel that belongs to the channel set and has been viewed by the user and has no save mark.
- it is determined whether the user has already viewed the content based on the viewing history in the channel assignment table.
- the length of time viewed is about the same as the length of recording time (the range must be determined in actual operation), it is regarded as viewed. For example, in the example of Fig. 14, Since the recording time length and viewing time length of No. 08 1 match, it is determined that the user has already watched the program of “Animal Village”.
- step 3 53 the number of channels searched is counted, and if it is 0, it is set to step 3 54, 1 is set to step 3 56, and if it is 2 or more, it is set to jump to step 3 5 5 I do.
- step 354 since there is no corresponding channel number, it is set as a channel candidate for securing the oldest recording channel from the channel set.
- step 356 multiple channel numbers could be searched, but among these, the channel candidate with the earliest recording date and time is selected as a channel candidate.
- step 356 the contents of the candidate channel numbers are moved to a temporary channel set. Here, the necessary and sufficient channels are reserved in advance so that the temporary channel set will not be insufficient.
