The present invention relates to an individual broadcasting recording channel service system and method, and more particularly, to a PVR of a service member remotely located through a common network with wired / wireless communication devices such as a personal computer terminal, a general telephone, a mobile phone, a PDA, and the like, which are Internet-enabled. The present invention relates to a personal broadcasting recording channel service system and method for conveniently recording general TV broadcasting programs, wired / cable / satellite / high definition digital broadcasting contents.

In recent years, with the start of digital broadcasting, the number of general TV, cable, cable, satellite, and high-definition digital broadcasting channels has increased to about 300.

In such a situation, it is almost impossible for a viewer to turn around the channel or find a desired broadcast program by operating a key or button on the remote control or a TV as usual, and moreover, the broadcast program can be viewed at a desired time. Recording is a more difficult and difficult situation.

In this situation, technologies for viewer convenience, such as an electronic program guide (EPG) and an interactive TV program guide (IPG), have been introduced.

EPG is an electronically processed TV program guide that serves as a guide to help viewers watch TV in a multi-channel, multi-media era. In other words, when comparing the EPG to Internet surfing and Internet portal sites, the EPG displays the TV program portal site screen on any one of the viewer's TV channel screens, but the TV program portal site screen itself has accumulated a plurality of blocks. It is composed of various complicated program guide information (including title, time, running time, channel number, etc.).

In other words, through the EPG, viewers can access contents such as a book called TV guidebook in the form of an electronic TV guidebook on their TV, and then find and enter a desired broadcast.

In this case, there is a disadvantage that the user must perform recording by using a program code called 'G-code' in order to record a program shown on the EGP.

In addition, IPG is an interactive television program guide, which interactively displays an operation menu to viewers for easy operation and operation on a modern digital TV or PVR. In particular, the IPG of the PVR is used for services such as the user selecting or recording a TV program (content), setting a viewing age limit, or setting a reminder, as known as an interactive TV service. .

A typical PVR has a built-in storage device such as a hard disk (HDD), which stores and plays an analog or digital video stream currently being broadcast in real time.

Such a PVR is equipped with a time shift function to simultaneously store and play a broadcast program being watched. For example, if you receive a call while watching a current program, press the Pause button on the remote control to store the received broadcast stream on the hard disk. After the phone call is over, press the Play button again to enter the hard disk. This allows you to watch from the scene after the paused picture. In other words, storage and playback are simultaneously performed at regular time intervals.

In addition, the PVR 1 according to the prior art, as shown in Figure 1, receives a transport packet (TP: Transport Packet) stream of the broadcast channel selected by the user through the antenna 3 and the tuner (4) video A transmission packet decoder 5 for parsing into an audio stream, an image decoder 7 for receiving a video stream parsed by the transmission packet decoder 5 and decoding the same and outputting the video stream to the display 6; An audio decoder 9 which receives an audio stream of the packet decoder 5, decodes it, and outputs the audio stream to the speaker 8, and a storage device which stores the transport packet stream bypassed without being parsed by the transport packing decoder 5 ( 12), an image encoder 10 for compressing the image decoded by the image decoder 7 and storing the compressed image stored in the storage device 12, and a compressed image stored in the storage device 12, Release the video decoder ( 7) an image decoder 11 for outputting to the control unit, and control means 2 for controlling the respective components.

The characteristic of the PVR of the prior art is to support the storyboard so that the user can immediately visually grasp the program content recorded in the PVR.

That is, the representative screen image which is a part of the program content stored in the storage device 12 by the image decoder 11 is synthesized with the detailed information of the broadcast programs and displayed on the display 6 through the image decoder 7, thereby providing a story. It is implemented as a board.

However, a user using a conventional PVR directly operates a remote controller based on guide information such as newspapers, announcements, and EPGs, which are in charge of guiding contents such as TV programs or channel broadcasting contents that are currently being screened or used. It is a situation that can not only record the content of the desired guide information.

That is, the user of the PVR is forced to record by directly operating a remote controller, a key, a button, even if the EPG or IPG technologies are remarkably developed.

In addition, even if the user of the conventional PVR, even if the internal function of the PVR is convenient, the individual must select and record the TV program, and in consideration of the capacity of the hard disk and delete unnecessary TV programs as a normal PC management problem To seal.

However, unlike PC, TV is the form that ordinary people feel most comfortable when they turn it on, but there are not many people who record and play in a more active form.

In other words, the existing VCR had various functions and seemed to be convenient to use, but there are not many people who use them to record and watch the program they want to see.

In addition, as the communication network develops, users can remotely record TV programs through a PVR or VCR, display scheduled recording lists on the user's TV screen, set TV program reservations, search, modify recording lists, Even if the deletion can be controlled remotely through a remote PC, such things are limited to the user's operation, so that the user has no choice but to record the broadcast by himself or the user's immature or accidental re-recording of the broadcast. There is discomfort that can not be done.

In addition, in relation to the remote control of the PVR, since the PVR is remotely controlled by a PC terminal or a data communication terminal, which is normally networkable, the network configuration becomes complicated, and the corresponding remote control application for each place or terminal requiring remote control. The program has to be installed, and remote control is not performed through a convenient telephone, etc., which is inconvenient to use, and the maintenance of the system is very inconvenient from the viewpoint of a system operator (service provider).

In particular, when the PVR is not connected to a high-speed network like a conventional PC, it will be insufficient to process both a control signal and a data signal for remote control according to the aforementioned conventional technology.

Accordingly, an object of the present invention is to provide a service system and method for individual broadcasting recording channel service that allows a user to remotely control a remote PVR from a service provider by using a new language, PvrXML, to conveniently record and watch various TV broadcast contents that are complex, various, and easy to miss. To provide.                         

In addition, another object of the present invention is to transmit a pre-planned recording scenario through a common network to the PVR of a plurality of subscribers in the form of PvrXML, so that the individual broadcast recording channel that can conveniently record the broadcast program desired by the user. To provide a service method.

In addition, another object of the present invention is that the user's PVR periodically saves the broadcast in the form of the corresponding content and recording list in its own hard disk according to the recording scenario, it is possible to use the personal program recording channel through the content and recording list. It is to provide a personal broadcast recording channel service method that makes it possible.

The objects of the present invention described above

In the present invention, the individual broadcast recording channel service, the PVR channel service, and the individual broadcast recording agent service mean a service having the same concept.

This means that a user who can use a terminal connected to a common network can record a predetermined broadcast program on his / her own PVR located at a remote location. It is a service that allows you to watch together.

For example, the PVR channel service is largely used to allow broadcast programs to be collectively recorded on each user's PVR according to a more detailed and pre-planned scenario by a service provider (PVR channel service provider) regardless of the user's intention. It is divided into broadcasting channel service method and simple remote recording service method that allows the corresponding program to be recorded on its own PVR as the user expresses his / her desired expression to the server through his available terminal. do.

That is, the broadcast channel service method records broadcast program content in a second storage device dedicated to channel content, and the simple remote recording service method records broadcast program content in a first storage device dedicated to personal content.

A user may use a communication technology related to a terminal available to him, that is, a wired internet communication technology such as a web method, a mobile communication technology including at least a WAP method, a telephone or a voice web, or an ARS (Automatic Response System). Service application / subscription / use / change / cancellation can be performed through communication technology and interactive TV broadcasting technology (IP).

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a diagram illustrating a network configuration of an individual broadcast recording channel service system according to an exemplary embodiment of the present invention, and FIG. 3 is a diagram for describing the structure of PvrXML illustrated in FIG. 2. 4 is a block diagram illustrating an internal configuration of the PVR shown in FIG. 2, FIG. 5 is a block diagram illustrating an operation relationship of the PVR shown in FIG. 4, and FIGS. 6 and 7 illustrate the present invention. Flow charts for describing a broadcast broadcasting channel service method for each individual.

First, as shown in Figure 2, the present invention relates to a technology using a PVR (300), a next-generation digital home appliances that replace the existing VCR.

The PVR 300 digitally stores (stores) and plays content on a hard disk (HDD, DVD), compresses and reproduces MPEG-2 standard, and video on demand (VOD) and audio on demand (MOD). PvrXML file 125 for PVR channel service of the present invention, while providing conventional functions such as Pay-Per-View (PPV), IPG, EPG, manual selective reservation recording, and the like. Remote control.

Through this remote control technology, the PVR channel service can record a broadcast program that a user wants or a broadcast program based on a recording scenario created by a user's taste predicted by a service provider.

For example, a service provider analyzes viewers' inclinations in advance and records new contents every day for each content such as news, drama, sports, music, etc. in the user's PVR. In this case, contents, recording lists, and channel recording guides corresponding to broadcast programs that are collectively recorded and stored as digital signals are available.

In the network configuration of the present invention for this purpose, a common network 20 including any one of a wired network, a wireless network, a public network (PSTN), an intelligent network, the Internet, a hypocrisy communication network, and a power line communication network (PLC) is used.

The common network 20 may input data through wired / wireless communication, such as a user's wired / wireless computer, wired / wireless phone, mobile phone, personal digital assistant (PDA), two-way TV, and the like. The terminal 30 which can output a predetermined interface screen is connected.

For example, in the case of a wired / wireless computer terminal, a mobile phone, or a PDA, after a user accesses a wired site or a wireless site for providing a service of the present invention, the user can subscribe to a PVR channel such as service application / subscription / use / change / termination.

In addition, in the case of a wired / wireless telephone terminal, the user calls the service telephone number of the service of the present invention and performs a voice command according to the ARS guidance of the service provider, thereby making a new member registration, member information modification, billing, membership withdrawal, You can use services such as recording reservation setting, recording reservation list checking, file deletion, inquiry and search of recorded information list and detailed contents.

In addition, in the case of the interactive TV, it can be applied / subscribed / subscribed through a subscription window on the TV monitor with a PVR controller (remote control, etc.) through IP communication.

The server side configuration of the present invention will be described.

It is preferable that the terminal 30 mentioned above basically uses a communication service to access the common network 20.

In the server-side system of the service provider of the present invention, the PVR channel service user interface 130 (hereinafter referred to as 'UI') supports web, WAP, ARS, VXML, channel broadcasting method, and power line communication method. It is preferably installed in the interface server 110 by conventional communication techniques and accessed through the common network 20.

The UI 130 for the PVR channel service mediates data input / output between users and service providers corresponding to communication standards of various terminal devices between the user terminal 20 and the interface server 110.

For example, a user encounters a PVR channel service screen on a mobile phone / PDA screen of a wireless site by using a template method of the UI 130, and applies a remote recording application to remotely record a program broadcast of a channel desired by the user on such a service screen. do.

In the remote recording application, the user performs a user input process for remote recording through the menu for the PVR channel service shown on the PVR channel service screen of the UI 130.

Through this process, the user terminal 20 transmits the user input data to the interface server 110, and the interface server 110 which has received the transmission of the user history data is described in the database 200 to 205, hereinafter, ' DB ').

Subsequently, the wizard / transmission server 120 interworking with the interface server 110 may display a result screen corresponding to the user input process by using the stored DB 200 to 205 and a template previously prepared by the service provider. Through the display window of the terminal 30 through.

That is, the wizard / transmission server 120 is equipped with a wizard engine written in any one of PHP / JSP / ASP programming languages, and publishes the UI 130 on a predetermined network, or the corresponding communication standard through the UI 130. Alternatively, data can be input and output in correspondence with the terminal 30.

The wizard / transmission server 120 supports the platform corresponding to the communication standard so that the common network 20 can be accessed, and is interlocked with the interface server 110.

For example, the PvrXML generation module 121 of the wizard / transmission server 120 may store various types of stored data of the DBs 200 to 205 in response to the input / output signals of the terminal 30 input through the interface server 110. It can be generated with the detailed information and 125, it can be transmitted to the PVR 300 of the user connected to the common network (20).

The interface server 110 includes a memory in which a predetermined program is stored, such as a typical web server, and a processor coupled to the memory to execute the program, and the processor stores, indexes, and reads data by the program. DB management function including processing, processing, web document, WP document, ARS template, etc., and web-based data management function to manage the input information as a predetermined DB item. It is desirable to be able to.

The wizard / transmission server 120 stores a program for the PvrXML generation module 121 for generating a PvrXML file 125 by parsing any one of data of a service DB including a recording scenario, a PvrXML tag, and user input data into a PvrXML format. A server side memory and a processor coupled to the server side memory to execute the program.

The wizard / transmission server 120 stores the PvrXML editing module 122 that can edit the PvrXML file 125 in the same program format in a server-side memory. The PvrXML editing module 122 is programmed to provide a function for editing a document including a normal XML tag.

The wizard / transmission server 120 stores the identification code management module 124 in the server side memory. Identification code management module 124 is to broadcast or individually transmit the PvrXML file 125 to the PVR 300 of each user connected in the common network 20, subscriber information, membership number, caller ID (Caller-) ID), the telephone number of the telephone line to which the PVR 300 is connected, the member ID, the serial number (S / N) of the PVR 300, the serial number of the PVR 300, or the IP address of the PVR 300. Process the identification code 380 corresponding to the data to be used in the PvrXML transmission module 123, and manages for each user.

The wizard / transmission server 120 stores the PvrXML transmission module 123 in the server side memory. PvrXML transmission module 123 is responsible for transmitting or separately PvrXML file 125 to the PVR 300 of a plurality of users having each identification code 380 managed by the identification code management module 124. do.

That is, the wizard / transmission server 120 including the modules 121 to 124 generates the recorded and stored information of the DBs 200 to 205 into the predetermined PvrXML file 125 by the PvrXML generation module 121.

The generated PvrXML file 125 is transmitted to the corresponding PVR 300 by the PvrXML transmission module 123 and the identification code management module 124, and the PvrXML interpreter of the PVR 300 transmits the received PvrXML file 125 ) Can be converted into control signals for middle-ware.

In addition, the PvrXML generation module 121 of the wizard / transmission server 120 merges the detailed information previously created and stored in the detailed information DB 201 by the service provider into the converted PvrXML file 125. Is programmed to perform

Here, the detailed information is preferably any one of text, image, voice, video data, or link information thereof.

In the process of merging the detailed information into the PvrXML file 125, the advertisement information, the advertisement image, and the description contents matching the keywords in the PvrXML file 125 are displayed by the DB management function of the wizard / transmission server 120. After reading from 201, the data is merged into the PvrXML file 125, thereby completing one transmission data file.

Wizard / transmission server 120 preferably further stores in memory a PvrXML editing module 122 operable by its processor and manually manipulated by the service provider.

Web DB (200), detailed information DB (201), member DB (202), PvrXML tag language DB (203), recording scenario DB (204), service DB (205) is an interface server coupled to work on a predetermined platform ( 110), the wizard / transmission server 120, a separate DB server (not shown) is stored in any one of the server-side memory.

Here, the web DB 200 records and stores all data and information to be used for Internet access.

As described above, the detailed information DB 201 refers to image, text, voice, and video data corresponding to a keyword of the PvrXML file content to be combined with the PvrXML file 125. The detailed information DB 201 may be converted into an advertisement image, an advertisement text, an advertisement voice, an advertisement video representing an advertisement desired by the advertiser, and select a program recorded by the user by the user's PVR 300. By being visually displayed on a menu corresponding to a graphical user interface (GUI), an advertisement exposure effect is provided to an advertiser and a detailed information providing effect is provided to a user at the same time.

The member DB 202 may be all member related information including a member name, a contact number, an address, PVR identification code related information, and a phone number.

The PvrXML tag language DB 203 means recording and storing the above-mentioned definition, structure, item, type, keywords related to a recording command in a recording scenario, and the like.

The recording scenario DB 204 is input by the service provider so that the service provider can represent the analysis information, which is optimally prepared in advance according to the user's taste, in consideration of viewer rating indexes such as age, gender, fashion, viewer popularity, etc. The keyword information refers to user input data input by the user through the terminal 30, the common network 20, and the UI 130. Such information or data may be recorded and managed by user or by age, viewer taste, gender, and occupation.

As mentioned above, the service DB 205 includes user input data input through the user terminal 30, identification code, information required for transmission of the PvrXML file 125, reservation setting time, and server-side PVR channel list for each member. Recording time, broadcasting type, channel, title, etc. are recorded and stored.

The following describes the structure of PvrXML mentioned above.

The structure of PvrXML is a kind of script language newly defined exclusively for PVR 300, and has a system of extensibility display language for PVR 300 suitable for small-capacity data. And a device identification code for service recording.

That is, the system of PvrXML includes at least one command structure that is 1: 1 matched with an PVR application programming interface (API) capable of controlling the operating system or middleware of the PVR 300.

Since PvrXML is simple and powerful, it can be operated anytime and anywhere using a PC or a wireless terminal using the Internet, and voice commands using a general telephone can be connected with VoiceXML.

In addition, PvrXML has the advantages of XML language, so you can define new PvrXML tags as needed, and have many additional features.

For example, the tag of PvrXML is as follows:

1. <pvr> </ pvr>: Tag to start connection with PVR,

2. <list> </ list>: a tag to select a recording list,

3. <title> </ title>: a tag showing the title of the selected pro,

4. <recordset> </ recordset>: tag to set the recording,

5. <attach> </ attach>: tag to add the action to,

6. <save> </ save>: a tag that saves the entire setting,

7. <record_list> </ record_list>: a tag showing the title of the recorded pro,

8. <delete> </ delete>: Tag to delete the recorded pro.

9. <pvr_end> </ pvr_end>: Includes tags to end all operations.

As shown in FIG. 3, the meaning thereof may be intuitively understood through the PvrXML file 125 defined as an example.

Referring to FIG. 3, the PvrXML conversion unit obtains corresponding recording scenario information from the recording scenario DB according to a series of recording scenario creation start commands corresponding to PvrXML creation of the processor of the wizard / transfer server.

For example, the recording scenario information to be stored in the recording scenario DB,

"1) Declare the version of PvrXML,

② Activate PVR,

③ Recorded the cable channel 315 for 2 hours from 14:00 on 04/03/08 and titled 'World Cup Soccer' with '040308 World Cup Soccer.mpg' in the sports storage folder (dir / contents / sports /). Save it,

④ Record TV channel 11 for 50 minutes from 22:00 on 04/03/08 and save it as '040308 Daejanggeum.mpg' in the drama storage folder (dir / contents / drama /) of the storage device with the title 'Daejanggeum'. ,

⑤ Recorded the cable channel 301 for 1 hour and 50 minutes from 23:00 on 04/03/08, with the title 'Memories of Murder' in the movie storage folder (dir / contents / movie /) of the storage device. mpg '

⑥ Delete '040307news.mpg' file in the news storage folder (dir / contents / news /) of the storage device.

⑦ Stop the PVR. "

May consist of a script statement.

In this case, as shown in FIG. 3, the PvrXML converter compares and checks the keywords of the recording scenario DB and the keywords of the PvrXML tag language DB in a 1: 1 ratio, and then matches the keywords with the PvrXML file (125). ).

For example, the PvrXML conversion unit reads " <pvr> </ pvr> " and " value = on &quot; corresponding to &quot; PVR &quot; and &quot; operation " By parsing it into a statement form, you end up with the phrase "<pvr> value = on </ pvr>".

When this process is repeated, the entire PvrXML file 125 as shown in FIG. 3 is created.

The client side configuration of the present invention will be described.

As shown in FIG. 4, the PVR 300 further includes a PvrXML interpreter 390, an input signal selection control unit 391, and a communication port 392, along with a conventional PVR hardware and software configuration.

The communication port 392 is coupled to a communication module 370 that supports any one communication standard such as telephone, LAN, power line communication (PLC), IEEE1394, and the like.

The communication module 370 uses the PVR identification code 380 recorded in any one of a memory and a PVR BIOS to perform the PVR identification process at the server side of the service provider through the common network. To the server of the service provider (wizard / transmission server). Therefore, when the server of the service provider transmits the PvrXML file 125 to the corresponding PVR 300, the server performs a normal data transmission path setting process using the identification code 380.

The channel recording guide 350 is installed in any one of the memory 308 of the PVR 300 or the first and second storage devices 360 and 361 in a predetermined firmware format, thereby recording content and recording in the PVR channel service. It is responsible for displaying the items in the list.

Of course, the channel recording guide 350 is preferably replaced with the storyboard or IPG, EPG provided by the existing PVR (300), or is preferably linked to these.

The PvrXML parser 390 corresponds to a PvrXML parser engine or a PvrXML interpreter engine, and corresponds to the API standard of the specific PVR 300 or the general API standard, but the PvrXML file 125 is communicated through the communication port 392. After receiving and interpreting the data, the contents of the PvrXML file 125 are parsed into a control signal for a corresponding middleware or a control signal in the form of an API of firmware.

Thereafter, the control signal output from the PvrXML parser 390 is input to the middleware 301 through the input signal selection controller 391.

The input signal selection control unit 391 checks the input signal input from the input unit 302 coupled to the control unit 303 and the control signal input from the PvrXML parser 390 to cause the middleware 301 to perform the check. To operate while displaying the operation state of the PVR 300 on the screen, or to perform an arbitration operation that selects one of the operations by the recording scenario of the PvrXML file 125 in the background of the screen. Have an electronic circuit or software algorithm.

The first storage device 360 records and stores a broadcast program by the PvrXML file 125 generated corresponding to the input data input by the user through the common network UI as private content only.

The second storage device 361 records and stores the broadcast program by the PvrXML file 125 unilaterally generated by the service provider as channel contents only.

The reason why the predetermined content can be recorded and stored separately in the first and second storage devices 360 and 361 is a device identification code that can identify whether a channel or personal is used in the header portion of the PvrXML file 125. Because it is included.

That is, the PvrXML parser 390 analyzes the device identification code and requests the controller 303 to record the recording position to one of the first and second storage devices 360 and 361.

According to the conventional PVR operation method, the display device connected to the PVR 300 is transparent to the display screen in the form of an interactive GUI in response to a reservation recording procedure through the user's input unit 302 after inputting a corresponding menu or command. To opaque overlay.

In addition, in the case of the recording scenario of the PvrXML file 125, the display device connected to the PVR 300 does not display all of the recording scenarios on the display screen, but only displays the minimum icon display degree that is being operated by the recording scenario. The display on the screen informs the user that only the PVR 300 is operating due to the recording scenario.

In the present invention, the input signal selection control unit 391 is preferably configured to allow the user to operate the PVR 300 in a manner such as stopping, stopping, canceling, or the like by operating the recording scenario.

The middleware 301 serves to input various commands to be performed by the controller 303 to the controller 303 through the PVR API.

The PVR 300 receives an airwave including an ATSC corresponding to the US digital broadcast signal standard and an NTSC corresponding to the US analog broadcast signal standard through the antenna 304. Of course, the present invention does not affect the PvrXML parser 390 even if the hardware of the PVR 300 is changed to correspond to the European digital and analog broadcast signal standards, so that the present invention can be applied regardless of the broadcast signal specifications.

Over-the-air can be understood as a TP (Transport Packet), which is a data unit for transmitting digital or digitized video.

It can be seen that TP proceeds in two directions.

First, when the TP is NTSC, a preprocessing process for generating a digital image using the MPEG-2 encoder 305 is required. That is, the TP has the same structure as the broadcast signal standard of a general digital TV through the MPEG-2 encoder 305 in charge of transport packet control, and then the control unit 303 having at least a stream control function with the TP interface 306. A display device (eg, a video and audio decoder 311, a video scaler 312, video / audio output terminals 313 and 314) and correspondingly connected to the respective output terminals 313 and 314, respectively. TV, monitor) or the speaker allows the user to watch the current analog broadcast.

In addition, if the TP is ATSC, it is directly input to the TP interface 306 and then enters the control unit 303, and thereafter, through the HOST / PCI 307, the memory 308, and the EIDE controller 309, the first and the second are Data may be stored in the storage devices 360 and 361 or a DVD-ROM (not shown).

In the PVR 300, the process of storing the TP in the first and second storage devices 360 and 361 as described above is a process of recording a TV program.

On the contrary, the TV program data stored from the first and second storage devices 360 and 361 are uploaded to the control unit 303 through the memory 308 in units of TPs, and the uploaded TV program data is a video and audio decoder as described above. 311, the video scaler 312, the video / audio output terminals 313 and 314, a display device, or a speaker are outputted to reproduce the recorded TV program.

Hereinafter, the operation method of the present invention will be described based on the operation relationship of the PVR 300.

As shown in FIG. 5, the recording scenario and detailed information of the service provider are prepared as transmission data on the server side (S1).

Thereafter, the prepared transmission data is converted into the PvrXML file 125 and the detailed information by at least one of a wizard / transmission server or an interface server including the PvrXML conversion unit, and the detailed information is merged into the PvrXML file 125 (S2). .

The PvrXML file 125 in which the detailed information is merged is transmitted to the PVR 300 of each individual who has subscribed as a member to the broadcast recording service of the present invention through a common network including a telephone, the Internet, and a LAN.

The PvrXML parser of the PVR 300 separates the PvrXML file 125 into PvrXML script statements and detailed information. The PvrXML interpreter of the PVR 300 parses the PvrXML script statement and parses it into a control signal for middleware, and records and stores detailed information in a storage device (where the storage device includes at least a memory and an HDD) (S3). .

The middleware of the PVR 300 instructs an operation command to the hardware inside the corresponding PVR based on a series of control signals input from the PvrXML parser (S5).

Therefore, the hardware instructed by the operation command performs an operation such as broadcast recording, and stores the TV program content in the form of data in the HDD or DVD-ROM (S6).

Thereafter, the user manipulates a button of a remote controller or a keypad to input a user's selection operation signal such as PVR playback to an input unit of the PVR 300 (S7).

In this case, a playback command is input to the control unit of the PVR 300 by the API of the operating algorithm or firmware of the software format stored in the middleware or the memory of the PVR 300 (S8).

The controller of the PVR 300 decodes data stored in a plurality of storage devices or DVD-ROMs and displays the same on a display device 320 such as a TV or a monitor of the user (S9).

Hereinafter, the above-mentioned individual broadcast recording channel service method will be described in the form of a server side flowchart and a client side flowchart as follows.

As shown in FIG. 6, at the server side, the interface server inputs information corresponding to membership in the member DB (S10); Receiving, by the interface server, information on the member's recording preferences from the member's terminal and inputting the information into a corresponding DB (S11); An interface server processing the information according to the viewer's disposition analysis and inputting the information into a corresponding DB (S12); Extracting and indexing a keyword from the input information, analyzing the member recording taste, and storing detailed information corresponding to the keyword in a detailed information DB (S13); Generating, by the wizard / transmission server, a recording scenario based on the detailed information related to the analyzed information (S14); Generating a recording scenario as a PvrXML format file by the PvrXML converter of the wizard / transmission server (S15); The wizard / transmission server transmits the PvrXML file and the detailed information to the member's PVR through the common network (S16).

The interface server receives the information on the member recording taste from the member's terminal and inputs it to the corresponding DB (S11), since the user uses the service of the present invention through the terminal and the UI directly available to the user. Through wired / wireless internet / two-way TV system, 2) mobile method, 3) ARS / VXML method, and 4) channel broadcasting method.

1) Wired / Wireless Internet / Two-way TV

In the UI using web, swap, IP (interactiv protocol), and power line communication, the web page of the PVR channel portal site in HTML format is displayed in the display (monitor) window of a computer, PDA, mobile terminal (mobile phone), and interactive TV. The user (service user, member) accesses the EPG of the web page after membership authentication. That is, the user selects one of the broadcast program titles from the list of broadcast programs on the EPG by manipulating any one of a mouse, a keyboard, a touch screen, a styler, and a remote controller.

In this case, the terminal transmits the input data corresponding to the selection through the UI to the service providing server (interface server or wizard / transmission server).

The server providing the service records and manages the received input data in the DB and shows the recording reservation scenario (list) on the display window of the user terminal in the form of a template using the input data.

The service providing server receives a user's modification and confirmation process signal for the recording reservation scenario from the terminal.

Thereafter, the service providing server generates the recording reservation scenario as a PvrXML file by the PvrXML generating module, and transmits the PvrXML file to the PVR of the user by the PvrXML transmitting module.

In addition, in a wired Internet site or an interactive TV, a broadcast program (channel) to be recorded can be selected while watching a trailer and a detailed description of contents in more various ways.

In addition, the wireless site can also schedule recording of a desired channel by selecting the PVR channel on the mobile phone / PDA screen.

2) Mobile method

For example, if you look at the usage of WAP, the main menu of TV recording appears on the screen of the mobile phone, and the submenu “1. Drama, 2. News, 3. Movie, 4. Entertainment” appears on the screen. . The user uses the keypad buttons of the terminal, but if press "1" to enter the drama submenu. The submenu of the drama again displays titles such as "1. Fireworks, 2. Snow White, 3. Dae Jang Geum, 4. Others". Therefore, the user presses the keypad buttons in the displayed order to perform DTMF input, so that user input data corresponding to the recording reservation scenario is transmitted to the service providing server, and then the PvrXML file is transferred to the user's PVR according to the same procedure. Is sent.

3) ARS / VXML method

You can enter individual commands in a convenient upper interactive language through ARS telephone (DTMF input) or wired / wireless service site, or copy a well-crafted PvrXML file and send it to your PVR through a wizard / transmission server. Do. In the case of an ARS phone, the present invention is possible similarly to the ring or coloring service type. for example,

Interface server: "Hello OOO member, this is PVR channel. Today World Cup soccer recording is 0, drama recording is 1, news recording is 2, movie is 3 ..."

Member: Press 1 or say "once" by voice

Interface server: "Fire 1, drama Snow White 2, ...."

Member: Press 1 or say "once" by voice

Interface server: "You recorded the MBC soap opera of April 26, 2004. Press 1 for confirmation and 2 for cancel."

In this way, revenue will be generated in the form of paid ARS, a service in which a user (member) selects and records a desired program. In this case, since the data changes and the scenario changes every day, VXML is more useful than the existing ARS, and it is preferable to use TTS rather than recording ARS contents.

4) Channel broadcasting method

In this way, the user does not need to access any terminal specifically for recording other than the subscription to the service of the present invention. This is because the service provider generates the PvrXML file according to the scenario planned in advance.

Through the above method, the service provider of the present invention can perform the billing on a monthly basis or per charge, similarly to a ringtone or coloring service.

In addition, once the PvrXML file is generated, it is automatically transferred to the member's personal PVR as described below.

That is, as shown in FIG. 7, in the client side, after the PvrXML interpreter of the PVR receives the PvrXML file and the detailed information, recording and storing the detailed information in the corresponding storage device (S20); Parsing, by the PvrXML parser, the script text of the PvrXML file into a control signal for any one of remote recording and channel guide control operation of the PVR, and inputting the parsed control signal into middleware (S21); Inputting, by the middleware, an operation command corresponding to the input control signal to the controller (S22); Recording and storing a TV broadcast program by the control unit according to the operation command (S23); Step S24 of inputting a user's operation signal to an input unit and popping up a menu screen on a screen of the display device; The recording list corresponding to the recorded and stored information is displayed on the menu screen, and when the user selects each item of the recording list, detailed information including an advertisement is further displayed on the menu screen. S25); In step S26, the recording content corresponding to the selected item is reproduced according to the user's operation signal.

When the menu screen is popped up (S24), it will be described in detail. Since the PVR of the present invention includes hardware such as an internet-enabled communication port, a banner picture file or a flash file (including simple text-based command data) flash: * .swf) may be included in the PvrXML file and transmitted, or a tag value for calling the URL in which the file is stored may be transmitted.

In this case, an icon, a picture, a banner advertisement, or the like indicating recorded content or contents (for example, "Daejanggeum cover") is displayed on the menu screen of the middleware, so that various menu screens can be viewed.

In this case, as shown in the prior art, by providing an image encoder or the like on the PVR itself, it is possible to show various menu screens on the menu screen than the storyboard is made.

For example, instead of displaying only "silmido" in the recorded movie menu, the silmido advertisement screen may be attached to be displayed with the description of the contents in the recording list.

That is, the configuration of the PvrXML tag of the present invention for controlling the recording list is as follows.

That is, it is possible to extend the attribute of a tag with "<recordset> title =" silido ", attach =" silido banner.jpg ", attach =" silido advertisement.swf ">", and the like.

By using such a function, banner advertising, which is a profit model that can provide the broadcast recording service of the present invention for free, becomes possible.

That is, by attaching a banner provided at the top of the recording list or search menu in real time, the user does not have to pay a monthly fee or a monthly fee separately using the service of the present invention, and differentiates the quality of VOD, MOD, recording scenarios, etc. You can provide users with sophisticated, more convenient, and richer premium services that are enough to pay dues.

In particular, the PVR manages the first storage device and the second storage device separately. That is, the first storage device records and manages the recorded content and the recording list set by the individual, and the second storage device records and manages the recorded content and the recording list set by the service provider.

As described above, the individual broadcast recording channel service system and method of the present invention freely uses a PVRXML, which is a remote PVR control language, and a PVR remote control service UI accessible through various user terminals, to free the PVR at home or anywhere. There is an advantage that can be used to control.

In addition, the individual broadcast recording channel service system and method of the present invention is a fun and beneficial broadcast program in a well-planned manner by a professional invention service provider in advance, even if the user does not perform a complicated and difficult reservation recording procedure himself or herself. By creating a control command for recording music and the like by category and providing the same to individuals, there is an advantage of providing a new service such as a personal PVR channel service to the user.

In this case, the user can watch the desired broadcast at any time using the PVR, like the pay-for-service VOD broadcast. That is, in the case of the existing VOD service, but pays for each program, by using the present invention, by simply recording the TV broadcast and storing it in the user's own PVR, according to the user's operation, the user's desired program is displayed on the menu. There is an advantage to simply select and watch.

In addition, the individual broadcast recording channel service system and method of the present invention has an advantage that it is convenient to use through various user interfaces (UI).

In addition, in the individual broadcast recording channel service system and method of the present invention, it is possible to generate revenue by attaching banner advertisements and the like on a GUI such as a recording list for playback, and receive a monthly fee through a premium service. It is a profit model that can be successful enough as a used business model.
