The present invention relates to broadcast information processing for a broadcast program, and more particularly, to store and retrieve program information in a database format in a set or set-top box (STB) capable of receiving digital or analog broadcasts. And regeneration.

Satellite and cable television broadcasting environments including airwaves are expanding their service to high quality digital broadcasting. In addition to the broadcast signal centered on high definition, various additional services suitable for a digital broadcasting environment are provided. A representative example of such a service is broadcast program information.

Broadcast program information, called an electronic program guide (EPG), is included in a broadcast signal and transmitted to a television or received by a television (TV) through various back channels, such as an Ethernet connection.

The additional information such as the EPG may be used for various purposes according to the needs of the manufacturer / user. For example, the TV may be automatically turned on or the channel is automatically switched at a time when the detailed information of the broadcast currently being performed or the program to be broadcasted is started, or when the broadcast desired to be watched starts.

In particular, when a broadcast program is recorded by a receiver having a personal video recorder (PVR) function, detailed EPG information of the corresponding recording can be stored together to be classified by title or genre or to search for recordings.

In this regard, a broadcast program may be transmitted through a plurality of channels, in which case the broadcast information for the broadcast program in each channel may be different.

Therefore, when recording such a broadcast program, one recording may have a plurality of broadcast information. For example, if a user records a broadcast program while switching channels several times, the broadcast information of the corresponding recording is stored because the broadcast information of the corresponding channel is stored whenever the channel change occurs without knowing what kind of broadcast information has been stored. The amount of can only be increased.

However, in the case of recording the broadcast program, it is not possible to know what broadcast information is stored in relation to the program, and thus the broadcast information is often stored due to channel switching during the recording.

Therefore, in the above case, there is a problem in that the recording space is wasted because the same information is repeatedly stored.

In order to solve the above problem, if the recording information is included in the recording, when the recording is terminated and registered in the recording list, a lot of information is connected to one program, a lot of processing time is required. There is a problem that is needed. In addition, in a SET or a set-top box having a PVR function, it is not currently widely used because of cost and development complexity to efficiently use a function for including contents of broadcast information.

Accordingly, in order to solve the above problems, the present invention intends to reduce the storage space and processing time by connecting the broadcast program that is recorded or scheduled to record by broadcasting the database information on the recorded broadcast program.

Accordingly, in order to achieve the above object, an example of a method of storing broadcasting information about recordings that are recorded or scheduled to be recorded including at least one program according to the present invention is the recordings. Generating an entry relating to broadcast information associated with each program included in the program; And linking each generated entry with a corresponding recording.

In this case, the method may further include determining whether a pre-generated entry exists regarding broadcast information related to any one program included in the recordings.

If there is no entry generated as a result of the determination, an entry regarding broadcast information related to the program may be generated.

In addition, each entry may include identification information for identifying corresponding broadcast information, information on the number associated with recordings, information on a title of a program in a connected recording, information about a channel on which a program in a connected recording is broadcast, and information in a connected recording. The program information may include at least one of information about a start time and an end time of the program, and information for identifying a location where the broadcast information indicated by the entry is actually stored.

Each of the recordings includes information for identifying the corresponding recording, information about the number of entries associated with the pre-generated entry, information on the title of the representative program among the programs included in the recording, and information about the channel on which the representative program is broadcasted. It may include at least one of information about the start time and the end time of the recording and information for identifying each of the connected entries.

In addition, the generated entry may be databased in a table format.

The connection may be a virtual link.

The virtual link may be a pointer of a storage unit in which the corresponding broadcast information is located or a unique identifier (ID) for accurately finding a table in which the corresponding broadcast information is stored and a specific entry in the corresponding table. .

If a particular program is recorded or scheduled to be recorded over a plurality of recordings and stored in a single file, an entry storing broadcast information related to the specific program is a file offset for accurately finding the start and end positions of the corresponding program. ) May contain information about

In addition, when a specific program is recorded or scheduled to be recorded over a plurality of recordings and stored in a plurality of files, the program may include a file pointer for each file or information about a unique identifier for distinguishing each file.

Each entry may be connected to n (n is 0 or more) recordings.

In addition, when n is 0, the entry may be deleted.

And generating an entry for each program included in the recordings.

The method may further include linking a pre-generated entry with respect to the broadcast information associated with each program and an entry about the generated program.

According to an exemplary embodiment of the present invention, an apparatus for storing broadcast information about recordings that are recorded or scheduled to be recorded, including at least one program, includes: a user input receiver configured to receive information about the recording or recording scheduled recording; And a recording unit configured to record or schedule a program according to the information about the recording or recording scheduled recording, and to generate an entry for broadcast information related to the recording or recording scheduled program to construct a database in a table format. Or a storage medium storing recording scheduled recordings and a database in a table format.

At this time, in generating the entry, the processor may determine whether there is an entry previously generated for the broadcast information.

The processor may control to generate an entry related to the corresponding broadcast information if the entry previously generated does not exist.

In addition, the processor may control to virtually link with the entry related to the broadcast information, if there is an entry previously generated as a result of the determination.

The processor may generate an entry related to a recorded or reserved recording program in the recording to build a database in a table format.

Other objects, features and advantages of the present invention will become apparent from the detailed description of the embodiments with reference to the accompanying drawings. In addition, the terminology used in the present invention was selected as a general term widely used as possible now. However, in certain cases, the applicant arbitrarily selected a term, and in this case, the meaning is described in detail in the corresponding part. Therefore, the terms used in the present invention should be understood as meanings of the terms rather than simply names of the terms.

Hereinafter, an example of a method and apparatus for processing broadcast information on a broadcast program according to the present invention will be described.

According to the present invention, when a broadcast program to be transmitted is recorded or scheduled to be recorded, duplicate information is stored only once by using a table for storing separate broadcast information in the process of storing broadcast information related to the recorded or scheduled recording program. And, in the case of overlapping, connecting with the corresponding information of the corresponding table.

Hereinafter, in order to explain the technical idea of the present invention, EPG information is described as the broadcast information as an example.

FIG. 1 illustrates an example of a database structure constructed according to the present invention, and FIG. 2 illustrates an example of an EPG information structure of recording material 1. FIG.

1 illustrates a recording information database configured for a recorded program, and a recording list and a database configured for the recording list are shown. In this case, the database may include a recording information database storing EPG information about recordings including at least one program and a program database for each program included in the recordings.

In the recording list provided in FIG. 1, there are four recordings in total from recording 1 to recording 4, and each recording may include at least one program.

For example, recording 1 has three programs: Preview magazine + VJ commando + 9 o'clock news, recording 2 has two programs: movie channel + entertainment relay, and recording 3 has two programs: 9 o'clock news + entertainment relay. , Recording 4 contains two programs: Weekend Drama + Preview Magazine.

In addition, each program may have n (n is greater than or equal to 0) EPG information.

Hereinafter, for convenience of explanation, it is assumed that each program has one EPG information. Therefore, the recording material 1 recording the program of the preview magazine, the VJ commando, and the 9 o'clock news has three EPG information, and the structure may be the same as that of FIG. The same is true of other recordings of recordings 2-4.

The four recordings of the recordings 1 to 4 contain a total of nine programs. However, among the nine programs, although they are actually one linked program, there may be a case where recording is made over several recordings.

In this case, the EPG information of the corresponding program may be stored in duplicate in the various recordings. When the data is redundantly stored as described above, unnecessary storage space and storage time are required, thereby reducing the efficiency of the system.

Accordingly, in the present invention, in storing EPG information about recordings including at least one program, an entry about EPG information related to each program included in the recordings is generated, and the generated entries are stored in a database in a table format. It is characterized by making a change. In addition, each entry and the recordings are connected by a virtual link, and overlapping EPG information is only connected to the pre-stored entry and the corresponding recording by the virtual link without separately generating and re-saving an entry.

In the present invention, the virtual link refers to a table in which a pointer of a memory in which corresponding EPG information is located, a table in which EPG information is stored, and a unique identifier for accurately finding a specific entry in the table.

In the present invention, the table refers to a structured data storage method including a table format using a database system.

Therefore, according to the present invention, since the EPG information is not stored in duplicate for a specific program, the efficiency of the system can be improved by reducing the storage space and the storage time.

In the following, the entry is called a recording information database entry.

In more detail, the present invention is as follows.

In the attached recording list of FIG. 1, a program called Preview Magazine is recorded over Recording 1 and Recording 4, a program called 9 o'clock News is recorded over Recording 1 and Recording 3, and celebrity relay is recording over Recording 2 and Recording 3. It became.

As described above, if the EPG information for the programs recorded over the plurality of recordings is the same in each recording, the EPG information for the programs included in the recordings 1 to 4 is actually six instead of nine. Therefore, according to the present invention, only six entries need to be generated instead of nine for each EPG information. The overlapping EPG information only needs to be a virtual link with the recording.

That is, the recording information database structure that stores EPG information for a total of nine programs included in the four recordings included in the recording list of FIG. 1 may have a total of six entries from database 1 to database 6. .

In FIG. 1, Database 1 (hereinafter referred to as 'recording information DB 1') is EPG information about a program called Preview Magazine, and Database 2 (hereinafter referred to as 'recording information DB 2') refers to EPG information about a program called VJ commando and database. 3 (hereinafter referred to as 'recording information DB 3') is EPG information about a program called 9 o'clock news, and database 4 (hereinafter referred to as 'recording information DB 4') is EPG information about a program called movie channel and database 5 (hereinafter referred to as 'recording information DB 3'). 'Recording information DB 5' is an EPG information about a program called entertainment weighting, and database 6 (hereinafter, referred to as 'recording information DB 6') may generate EPG information about a program called a weekend drama series as an entry.

When the virtual recording is linked to each of the recordings and the entry in the recording information database, the recording 1 includes a preview magazine, a VJ commando and a 9 o'clock news, and the recording 1 includes recording information DB 1, recording information DB 2, and recording information. Linked with DB 3, it has three virtual links. In the case of the recording 2, the movie channel and the entertainment includes a program called a relay. The recording 2 is linked with the recording information DB 4 and the recording information DB 5 and has two virtual links. The recording 3 includes a program called 9:00 news and entertainment relay, and the recording 3 is linked with the recording information DB 3 and the recording information DB 5 and has two virtual links. The recording 4 includes a program called a weekend soap opera and a preview magazine. The recording 4 is linked with the recording information DB 6 and the recording information DB 1 and has two virtual links.

That is, in FIG. 1, each recording has virtual links as many as the number of programs included, and thus recordings 1 to 4 have nine programs and nine virtual links. However, the number of entries in the recording information database is only six, and the recording information DB 1, which stores duplicate EPG information, that is, EPG information about a program called preview magazine, has two virtual links. The recording information DB 3 storing the EPG information has two virtual links, and the recording information DB 5 storing the EPG information for the entertainment program, also has two virtual links.

However, even if a program of the same title is transmitted through different channels and each EPG information is different from each other, an entry for each should be configured.

Eventually, the recording information database according to the present invention constitutes an entry for the programs included in each recording and connects them through a virtual link. At this time, in configuring the entry, only one entry for a program existing in the recordings is duplicated, and the virtual link is further provided as much as the duplicate. Therefore, in FIG. 1, the total number of programs included in the four recordings is nine, of which EPG information for preview magazine, nine o'clock news, and entertainment relay are the same, and thus overlapping, virtual link without separate recording information database entry. Only put in the process.

Similar to the concept of the recording information database described above, the names of programs recorded over a plurality of recordings can be databased and connected using a virtual link.

This is the program database of FIG. 1, and as described above, an entry may be configured for a program name included in each recording and may be databased in a table form.

This can be configured in the same manner as for generating the above-described recording information database structure.

If a program database is constructed as described above and a virtual link with an associated entry in the recording information database structure, it is possible to control a recorded program over a plurality of recordings.

As shown in FIG. 1, the entry of the program database is referred to as database 1 (hereinafter referred to as 'program DB 1'), the preview magazine as database 2 (hereinafter referred to as 'program DB 2'), and database 3 (hereinafter referred to as 'program DB 2'). DB 3 '), 9 o'clock news, Database 4 (hereinafter referred to as' Program DB 4 ') Movie channel, Database 5 (hereinafter referred to as' Program DB 5 ') Entertainment entertainment relay, Database 6 (hereinafter called' Program DB 6 ') can be configured as a weekend drama series.

As described above, recording information DB 1 and program DB 1, recording information DB 2 and program DB 2, recording information DB 3 and program DB 3, recording information DB 4 and program DB 4, recording information DB 5 and program DB 5, And by virtually linking the recording information DB 6 and the program DB 6, various functions can be implemented.

For example, if the receiver includes the above-described recording information database and a program database, the user can search by program unit even when a specific program is recorded over a plurality of recordings. Therefore, when a user searches for a program called a preview magazine in FIG. 1, it can be seen that the program is recorded over recording 1 and recording 4.

In addition, a function such as playing, continuously playing or deleting, editing, changing a title, and saving to an external device can be implemented as if the program searched above is stored in a single recording using a virtually linked recording information database.

3 shows another example of a database structure constructed according to the present invention.

1 is a diagram illustrating a recording information database and a program database configured for a recorded list, FIG. 3 illustrates a recording information database and a program database configured for a recording scheduled list.

In this case, the recording information database and the program database of the recording scheduled list of FIG. 3 are the same as those described for configuring the recording information database and the program database of FIG. 1, and the detailed description is omitted here. do.

In the above-mentioned program of FIG. 1 or 3, the preview magazine is recorded over two recordings (recording 1 and recording 4), and the recorded program may be divided and stored in at least one file. If it's stored in a pie, each recording information database stores a file offset that can accurately locate the program's start and end locations.

However, if a program is divided into multiple files and stored, the recording information database must have a unique value (unique ID) for identifying each file or a file pointer for each file.

4 is a diagram illustrating in detail the structure of the recording information database structure constructed according to the present invention. (A) of FIG. 4 shows a list of programs that are recorded or scheduled to be recorded, (b) shows a list of recorded or scheduled recording sections for one item, and (c) shows recording or recording. A list of reserved EPG information is shown, and (d) shows a storage device.

In addition, since a plurality of EPG information may be linked to one item, a table having connection information for each recording is required.

Finally, each connection information is linked with a table containing EPG information.

4 illustrates this structure as an example, and the table configuration and storage information may be changed. But the basic skeleton is that each program has n (n is greater than or equal to 0) EPG information associated with it.

Referring to the attached Figure 4 in more detail, as follows.

Referring to FIG. 4 (a), each recording includes information (identification ID) for identifying the recording, information about the number associated with the pre-generated recording information entry (number of EPGs), and a representative program among the programs included in the recording. Information on the title of the representative (representative title), information on the channel on which the representative program is broadcasted (representative channel), information on the start time and the end time of the recording (start time and end time) and the respective recordings It may include at least one of information (EPG ID) for identifying the information entry. Therefore, information about the recording can be read through the EPG ID.

4 (a) is described with reference to a list of recording or recording reservations, and FIG. 4 (b) is for explaining a section list for each item of FIG. 4 (a).

Referring to FIG. 4B, each list includes information for identifying a corresponding recording (record ID), information about a sequence of pre-generated recording information entries (EPG order), and each recording information entry. Information (EPG ID) may include at least one of information on the position (start position) and information on the end position (end position) regarding the information having the EPG ID.

Looking at the structure of the recording information database in relation to the above-described Fig. 4 (a) to (b), it is as shown in Fig. 4 (c).

In FIG. 4 (b), four EPG IDs are 1001, 1002, 1003, and 1005, and 1001 is present in recording ID 21 and recording ID 7 respectively, and the total of two EPG IDs is 1002, recording ID 21, and recording ID. Each of 51 and recording ID 7 exists in total, and 1003 exists in one recording ID 21 only, and 1005 exists in recording ID 21 only.

Accordingly, the recording information database of FIG. 4 (c) includes identification information (EPG ID) for identifying corresponding EPG information, information about the number of linked recordings (link), and information about a title of a program in the linked recording (title). Information about the channel where the program in the connected recording is broadcast (channel), information about the start time (start time) and ending time of the program in the connected recording (end time), and the broadcasting information indicated by the entry. It may include at least one of information (stored A / V file ID) to identify the.

By making a database as shown in FIG. 4 (c), the EPG information for seven programs in each recording of FIG. 4 (b) can be processed with only four entries.

4 (d) shows a hard disk or a mass storage device, and the stored A / V file ID of FIG. 4 (c) can be seen as indicating the position in FIG. 4 (d).

Next, a simple example of implementing the structure of each program information is as follows. 5 illustrates an example of implementing the structure of each program information according to the present invention.

In FIG. 5, DVR_EPG_T represents the most basic program information.

DVR_EPG_SEGMENT_T represents a section in which a program is stored and a pointer to the DVR_EPG_T. The DVR_EPG_SEGMENT_T may be implemented as an array or a linked list.

The DVR_EPG_INFO_T represents a pointer embodied as a list in which the information stored in each recording list and the DVR_EPG_SEGMENT_T are linked.

6 illustrates an example of a broadcast system for transmitting and receiving EPG information according to the present invention.

The transmitter may separately transmit EPG information or include it in a broadcast signal.

Accordingly, the receiving end receives the separately transmitted EPG information through a separate EPG receiver or when included in a broadcast signal and receives the tuner through a tuner and stores the same as the broadcast signal or separately stores only the EPG information. It can be decoded and used when necessary.

Hereinafter, the receiver of FIG. 6 will be described in more detail. 7 illustrates an example of a digital broadcast receiver configured according to the present invention.

The digital broadcast receiver configured according to the present invention includes a tuner unit 701, a demodulator 702, a demultiplexer 703, and a program specific information / program and system information protocol (PSI / PSIP) decoder ( 704, PSI / PSIP Database (705), A / V Decoder (706), Channel Manager (707), Channel Map (708), External Input Receiver (709), Application The controller 710, a flash memory 711, a display 712, a DVR (PVR) processor 713, and a storage medium 714 may be provided. In this case, the digital broadcast receiver may be, for example, a digital television capable of receiving digital broadcasts.

The tuner 701 receives the digital broadcast signal and transmits the result of the received broadcast signal to the channel manager 707 under the control of the channel manager 708.

The demodulator 702 demodulates the signal received by the tuner 701.

The demultiplexer 703 demultiplexes audio, video, and PSIP table data from transport packets received from the demodulator 702.

At this time, the demultiplexing of the PSIP table data is controlled by the PSI / PSIP decoder 704, and the demultiplexing of audio and video is controlled by the channel manager 707.

The demultiplexer 703 creates and outputs sections of a desired table in the PSI / PSIP decoder 704 from the received transport packets.

The demultiplexer 703 demultiplexes the A / V elementary stream and outputs a virtual channel desired by the channel manager 707.

When the PSI / PSIP decoder 704 collects the corresponding table sections from the demultiplexer 703 and transmits them, the PSI / PSIP decoder 704 receives and parses the table sections. It is read and recorded in the PSI / PSIP database 705.

The channel manager 707 may request to receive the channel related information table and receive the result with reference to the channel map 708. At this time, the PSI / PSIP decoder 704 controls demultiplexing of the channel related information table and transmits an A / V PID list to the channel manager 707.

The channel manager 707 controls the A / V decoder 706 by directly controlling the demultiplexer 703 by using the received A / V PID.

The application controller 710 controls a graphical user interface (GUI) for displaying a state of the receiver system on an on screen display (OSD).
