Description

  The present invention relates to a program recording / playback system, a program recording / playback server, a program receiving terminal, and a program guide generation method for distinguishing among programs that have already been viewed from among recorded programs.

  In Japan, terrestrial television broadcasting is being digitized. In 2011, digital terrestrial broadcasting will be implemented nationwide, and analog waves will be stopped.

  In terrestrial digital broadcasting, there are several services that were not available in conventional terrestrial analog broadcasting. One of them is EPG (Electrical Program Guide). This EPG is created on the basis of a table called EIT (Event Information Table) included in radio waves of terrestrial digital broadcasting, and shows program information such as program broadcast time, broadcast station, title, and broadcast content. It is. In addition, in terrestrial digital broadcasting, compared to conventional terrestrial analog broadcasting, it is possible to provide more stable video for broadcasting for mobile reception and mobile reception, so there are cases where a user views a program on the go. It is expected to increase.

  In recent years, it has become possible to record a plurality of programs for a long time by installing a mass storage device such as a hard disk drive (hereinafter referred to as HDD) in the program recording / playback apparatus. In addition, since the HDD can randomly access a plurality of recorded programs, when a program is selected from a plurality of recorded programs and played back, it is as if recording was performed using a video tape. In addition, it is not necessary to reproduce a plurality of recorded programs in order from the beginning or to fast-forward for a long time, and reproduction can be started directly from a desired program. However, as the capacity of the HDD increases, the larger the number of programs that can be recorded, the more difficult it becomes to search for a desired program when it is played back.

In this way, when searching for a desired program from a program recording / playback apparatus in which a plurality of programs are recorded, a list of recorded programs is displayed, and the display contents are added to the recording date / time and channel number of the recorded programs. A technique for displaying information indicating how far each program has been reproduced and a thumbnail image is known (for example, Patent Document 1).

  However, in the technique described in Patent Document 1, a program viewed by a device other than a program recording / playback apparatus in which a plurality of programs are recorded, for example, a program receiving terminal such as an in-vehicle mobile receiving terminal or a portable receiving terminal is used. Since the programs viewed in the above cannot be distinguished and displayed, there is a problem that it becomes difficult for the user to check which program has been viewed.

  The present invention has been made to solve such a problem. When a list of programs recorded in the program recording / playback server is created, the program received by the program receiving terminal and viewed An object of the present invention is to allow a user to easily identify which program has been viewed by displaying the middle program and an unviewed program in an identifiable manner.

  In order to solve the above-described problem, in the present invention, when creating a list of programs recorded in the program recording / playback server, viewing data for specifying a program viewed at a program receiving terminal; The program data for specifying the program recorded in the program recording / playback server is compared, and when the program specified by the viewing data is present in the program recorded in the program recording / playback server, the program receiving terminal The display format in the list of programs viewed is changed.

  According to the present invention configured as described above, when the program recorded by the program recording / playback server and the program viewed by the program receiving terminal are the same, the program has already been viewed or Since it is displayed in a distinguishable manner that the user is viewing, when the user views the program, the user can easily identify the program that has been viewed, the program that is being viewed, and the program that has not been viewed. You can select and watch programs well.

In the program name column of this program guide, the display format is changed depending on whether each program has been viewed, being viewed, or not viewed.

  Reference numeral 5 denotes a receiving antenna that receives radio waves of terrestrial digital broadcasting sent from the transmission facility 1. Reference numeral 6 denotes an in-vehicle program receiving terminal (corresponding to the program receiving terminal in the claims), which extracts audio data, video data, and EPG data (for example, EIT) from the terrestrial digital broadcast wave received by the receiving antenna 5. To do. The in-vehicle program receiving terminal 6 extracts NIT and TOT (Time Offset Table) for acquiring the current time in addition to EPG data. Furthermore, the in-vehicle program receiving terminal 6 generates viewing data for specifying a program viewed by the in-vehicle program receiving terminal 6.

  The viewing data is composed of information indicating the name of a program being viewed, broadcast date and time, broadcast station obtained from EPG data, and information indicating viewing time obtained by TOT. The viewing data is generated when a program is viewed for a predetermined time (for example, 30 seconds) or more so that a program that has been viewed for only a short time is not determined as a program that has been viewed or a program that is being viewed. Since the viewing data has information indicating the viewing time of the program, the viewing data has been viewed according to the viewing time of the program (for example, the proportion of the viewing time is 90% or more with respect to the broadcast time of the program) or is being viewed (for example By setting the ratio of viewing time to the broadcast time of the program to be less than 90%, it is possible to distinguish whether the program has been viewed, being viewed, or not being viewed.

  The in-vehicle program receiving terminal 6 includes means for communicating with the program recording / reproducing server 4, and at least viewing data can be transmitted from the in-vehicle program receiving terminal 6 to the program recording / reproducing server 4.

The control unit 22 generates viewing data based on the program information stream decoded by the program information decoder unit 29. The viewing data is a viewing history management table indicating a viewing history of a program viewed by the in-vehicle program receiving terminal 6 and is data for specifying a program viewed by the in-vehicle program receiving terminal 6. As shown in FIG. 5, the viewing history management table is composed of information indicating a broadcast station identifier indicating a broadcast station, a program name, a program start time, a program end time, a viewing date and time, a viewing start time, and a viewing end time. .

  Reference numeral 30 denotes a storage unit that stores viewing data generated by the control unit 22. Reference numeral 31 denotes a data communication unit that periodically transmits the viewing data stored in the storage unit 30 to the program recording / playback server 4.

  FIG. 6 is a flowchart showing the operation of the program recording / playback system and the program guide generation method according to the present embodiment. Although not shown in this flowchart, the program recording / playback server 4 automatically stores the program in the recorded data storage unit 13 based on, for example, preference information indicating a program preferred by the user. In the program recording / playback server 4, when a program to be continuously recorded is set, the program is automatically recorded. Further, when a recording reservation is made by designating a recording date and time, or when a recording instruction is given in real time when the program is broadcast, the program is recorded in the recording data storage unit 13. Then, program data for specifying the stored program is stored in the program data / viewing data storage unit 15.

  On the other hand, the in-vehicle program receiving terminal 6 starts the process of the flowchart when viewing of the program is started. First, the control unit 22 checks whether or not the program has been viewed for a predetermined time or more (step S1). When the program is viewed for a predetermined time or longer (YES in step S1), control unit 22 generates viewing data and stores it in storage unit 30 (step S2). Then, the control unit 22 checks whether or not the transmission timing has come (step S3). Here, the transmission timing is regularly reached. On the other hand, if the program has not been viewed for a predetermined time or longer (NO in step S1), the process is terminated.

  When the transmission timing comes (YES in step S3), the control unit 22 reads the viewing data from the storage unit 30, and transmits the viewing data from the data communication unit 31 to the data communication unit 16 of the program recording / playback server 4. (Step S4), the process ends. On the other hand, when the transmission timing is not reached (NO in step S3), the process returns to step S3.

  When receiving the viewing data from the in-vehicle program receiving terminal 6, the program recording / playback server 4 stores it in the program data / viewing data storage unit 15 (step S5). Thereafter, the control unit 12 checks whether or not there is a program guide display instruction from the user (step S6). If no program guide display instruction is issued (NO in step S6), the process in step S6 is repeated. On the other hand, when the user gives an instruction to display the program guide using operation unit 11 (YES in step S6), control unit 12 transmits the program data stored in program data / viewing data storage unit 15 and data communication unit 14 Is compared with the viewing data stored in the program data / viewing data storage unit 15 to check whether the program specified by the viewing data is stored in the recorded data storage unit 13 (step S7). ).

  When the program specified by the viewing data is stored in the recorded data storage unit 13 (YES in step S7), the control unit 12 sets the display format of the program specified by the viewing data as the display format of other programs. Differently, program guide data is generated (step S8). At this time, the control unit 12 determines whether the program has been viewed or is being viewed according to the ratio of the viewing time with respect to the broadcast time of the program specified by the viewing data, and as shown in FIG. Different formats. On the other hand, when the program specified by the viewing data is not stored in the recorded data storage unit 13 (NO in step S7), the control unit 12 generates the program guide data with all the programs in the same display format ( Step S9).

  When generating the program guide data (step S8 or step S9), the control unit 12 instructs the OSD control unit 19 to output the program guide data. The OSD control unit 19 outputs the program guide data to a display (not shown) (step S10).

  When the user operates the operation unit 11 and selects a desired program from the programs displayed in the program guide in a state where the program guide is displayed, the control unit 12 displays the recording data of the selected program. The data is read from the recorded data storage unit 13 and reproduction processing is performed.

  As described above in detail, according to the present embodiment, when a user views a program on the in-car program receiving terminal 6, the viewing data specifying the program is transmitted to the program recording / playback server 4 installed in the home or the like. To do. When the program is the same as the program recorded by the program recording / playback server 4, the program guide created by the program recording / playback server 4 displays that the program has been viewed or is being viewed. I am doing so. Thereby, when a user views a program recorded on the program recording / playback server 4, it is possible to easily determine a program that has already been viewed on the external in-vehicle program receiving terminal 6 or a program that is being viewed. The user can select and view a program efficiently.

  In the present embodiment, when comparing the program specified by the viewing data sent from the in-vehicle program receiving device 6 with the program specified by the program data generated by the program recording / playback server 4. The program name, the broadcast date and time, and the broadcast station are used. However, when the program name includes detailed information such as a subtitle, only the program name may be compared. When there is a program ID that can specify a program, only the program ID may be compared.

  In the present embodiment, the viewing data is transmitted by the in-vehicle program receiving terminal 6, but is not limited thereto. For example, a mobile phone or a mobile terminal having a program receiving function may be used.

  Furthermore, in this embodiment, viewing data is periodically transmitted from the in-vehicle program receiving terminal 6 to the program recording / playback server 4, but the present invention is not limited to this. For example, when near field communication such as DSRC or Bluetooth is used for communication between the in-vehicle program receiving terminal 6 and the program recording / reproducing server 4, transmission from the in-vehicle program receiving terminal 6 to the program recording / reproducing server 4 May be linked to an in-vehicle navigation device. For example, a place where the program recording / playback server 4 is installed (for example, a home) is recorded in an in-vehicle navigation device, and the in-vehicle program receiving terminal 6 is connected to the in-vehicle navigation device when the vehicle approaches the location. Viewing data is transmitted according to instructions from. Thereby, communication with the vehicle-mounted program receiving terminal 6 and the program recording / reproducing server 4 can be performed reliably.

  In the present embodiment, the viewing time of the program in the in-vehicle program receiving terminal 6 is obtained by the viewing date / time, viewing start time and viewing end time of the viewing history management table shown in FIG. 5, but is not limited thereto. For example, the viewing time may be measured by a timer (not shown) provided in the control unit 22.

  Furthermore, in the present embodiment, a program that has been viewed, a program that is being viewed, and a program that has not been viewed are displayed in different columns in the program name in the program table, but the present invention is not limited to this. For example, as shown in FIG. 7, a display that serves as a mark may be displayed in the vicinity of the program name column so that a program that has been viewed, a program that is being viewed, and an unviewed program can be distinguished.

  Further, in the present embodiment, a viewed program, an unviewed program, and an unviewed program may be extracted from the displayed program table as shown in FIG. For example, as shown in FIG. 8, a display filter content setting screen for selecting a program that has not been viewed, a program that is being viewed, or a program that has already been viewed is displayed. A program may be selected and displayed in a list. Accordingly, when it is desired to exclude a program that has been viewed once, to view a program viewed on a mobile terminal at home, or to transfer a program that has been viewed and liked to another storage medium, the program recording / playback server The user can easily select a desired program from among the programs stored in 4.

  In the present embodiment, the program recording / playback server 4 stores the recording data including the audio data and video data of the program in the recording data storage unit 13, and the viewing data and program data in the program data / viewing data storage unit 15. Although remembered, it is not limited to this. For example, the recording data storage unit 13 and the program data / viewing data storage unit 15 may be the same storage device, and the data storage unit that stores the viewing data and the data storage unit that stores the program data may be separated.

  Furthermore, in this embodiment, the display format is changed according to the ratio of the viewing time to the broadcast time of the program specified by the viewing data, but the viewing time information indicating the time when the program is viewed is reflected in the program table. By doing so, it may be displayed how long the program has been viewed. For example, as shown in FIG. 9, the degree of viewing from the program start to the program end of the program displayed in the program guide is displayed in the length of a bar graph. Thereby, the user can know in detail the degree of viewing of the program.

  Further, as described above, when a bar-shaped graph indicates how long a program has been viewed, a program viewed by the program recording / playback server 4 is specified as shown in FIG. The display format of the part viewed on the program receiving terminal 6 and the part viewed on the program recording / playback server 4 may be changed. The user can select the part viewed by the in-car program receiving terminal 6, the part viewed by the program recording / playback server 4 and the part not viewed by the cursor indicating the viewing start position. Viewing can be started from the part. As a result, when the program that has been viewed halfway through the in-vehicle program receiving terminal 6 is viewed continuously by the program recording / playback server 4, or the portion that has been viewed by the in-vehicle program receiving terminal 6 is viewed again by the program recording / playback server 4. In some cases, the viewing start position can be easily specified.

  In addition, the said embodiment is only what showed the example in implementation in implementing this invention, and, as a result, the technical scope of this invention should not be interpreted limitedly. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
