4 is a flowchart showing a specific implementation of the PVR control method according to the present invention.

The present invention relates to a PVR control method and a system therefor. More specifically, the present invention relates to an agent-based PVR control method and a system therefor.

To watch the desired program, the user can move to the desired channel through the channel up / down keys to find a channel broadcasting the program. Unlike analog broadcasting systems, digital broadcasting systems deliver various programs to users through tens or hundreds of channels. Therefore, the above viewing method has a problem that it takes a long time to search for a desired channel. Occasionally, a user may enter a channel number directly to watch a desired program. However, this requires knowing in advance which channel the program to watch is being broadcast.

In order to improve the viewing convenience of the user, reserved viewing for reserving a program to be viewed in advance is used. However, in the conventional reservation method, a channel to be watched is selected in advance and stored in a memory, and when a corresponding time is reached, the channel is automatically moved to a channel where the corresponding program is broadcast. However, this approach does not satisfy the various needs of the user.

The most efficient way of viewing a program is to memorize all the channels at which time the program the user wishes to watch is broadcasted. Then, the channel is directly input at the time when the program is broadcast. For example, suppose you want to watch the program "STREET SIGHT" through channel number 1 at 5 o'clock, and you want to watch the program "MUSIC BOX" through channel number 99 at 6 o'clock. After memorizing all of these, the user watches another channel, then tunes to channel number 1 at 5 o'clock to watch program "STREET SIGHT", and then moves to channel number 99 at 6 o'clock to watch program "MUSIC BOX". Just do it. However, it is almost impossible for a viewer to memorize all of these things, and it is also undesirable to force them on the viewer.

To facilitate the selection of various programs offered through hundreds of channels, electronic program guides (EPGs) are provided in various forms. EPG refers to broadcast program guide information displayed on a screen of a digital television or an application for operating the same. The EPG application is one of the core applications of digital television. The application receives a TV program-related information from a server and processes it in a manner that is easy for the user to view. The EPG, which summarizes and displays the schedule of broadcasting programs, is an essential element. For more details on EPG, see Korean Patent Registration Nos. 331,834 and 400,010.

The user is recording a desired program based on the EPG information. A system employing a storage medium such as a PVR (PERSONAL VIDEO RECORDER) or a DVR (DIGITAL VIDEO RECORDER) is provided to record a program to be watched. Regarding the storage of a program using a storage medium and the like, see US Pat. Nos. 4,839,743, 5,109,482, 6,895,171, and the like. The system having the PVR or DVR function is provided with a storage medium, and the user can record and view the desired information while the TV is being watched. However, the terminal having the PVR (or DVR) function (hereinafter referred to as "PVR box") is not generalized because the price of the system having the function is high.

The recording reservation scenario of a program using an existing PVR box is briefly described as follows.

1. The user schedules recording through the remote control and recording menu of the PVR box.

2. The user can view the recording schedule list and manage the recording progress, completion, and cancellation of the reservation through the remote control and recording menu of the PVR box.

3. The PVR box records the broadcasted program according to the recording schedule list.

However, in the conventional method, only a user can schedule recording of a broadcast program, and a method provided by various menus for reservation recording of a broadcast program has to be used. This method has the following problems or limitations.

1. The user cannot make a reservation or not make a recording reservation.

2. If a program is scheduled to air on a date when the program schedule is not yet available, the recording cannot be scheduled.

3. Reservations for programs that are likely to be viewed based on viewer ratings or keywords of interest should be manually reserved after being separately inquired by the user.

Korean Patent Publication No. 601839 discloses a personal broadcast recording channel service system that provides individual PVR channel services to a plurality of PVRs through a common network, and provides a user interface for a PVR channel service that accesses a corresponding communication terminal in the common network. An interface server coupled to control data input / output signals for any one of subscription / use / change / cancellation of a PVR channel service through the interface; And a management server sharing a database stored through the interface server, wherein the management server generates a PVR XML file for each individual using the database and transmits the PVR XML file to the PVR. Is starting. However, the system requires user information to be transferred from the user side PVR box to an external server. This cannot prevent the damage caused by leakage of personal privacy information such as recording of the viewing channel of the user at the server side, and it is difficult to consider information on the current state of the PVR box and the current viewing state of the user. On the server side, a member DB, a member detailed information DB, and the like must be constructed, which makes the server system complicated. Furthermore, the method suffers from the need to deliver each PVR XML file individually to each user since the PVR XML file is generated for each user. This is subject to the restriction that the PVR XML file must be delivered only through the network.

In particular, in the case of control based on an instruction or markup language such as the PVR XML, an undefined exception can not be processed, and a conditional situation that requires different control according to various conditions such as the state of a PVR box is required. Difficult to handle. Also, the markup language itself is well extensible, but the markup language interpreter lacks the provision for when this expansion occurs.

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

1 is a block diagram showing a preferred embodiment of a PVR control method and a system therefor according to the present invention, and FIGS. 2 and 3 are flowcharts showing a preferred embodiment of the PVR control method according to the present invention. 4 is a flowchart showing a more preferred embodiment of the PVR control method according to the present invention. Referring to Figures 1 to 4 the preferred embodiment of the present invention will be described in more detail.

As shown in Figure 1, the method and system according to the present invention comprises a PVR agent providing server 200 and PVR boxes (100a to 100n, "100" in combination). The PVR agent providing server 200 transmits a PVR agent program to a plurality of user-side PVR boxes 100 defining a recording scenario of the program. At this time, the PVR agent program is common to all PVR boxes. In other words, the PVR agent program does not contain specific information about the user. As used herein, "specific information about a user" refers to information that applies to a specific user. The "specific information about the user" may be understood as specific user identification information or specific PVR box identification information. Since the PVR agent program does not include specific information about the user, the same PVR agent program is provided to all PVR boxes 100.

Since the PVR agent program does not include specific information about a user, the PVR agent program may be transmitted through a broadcasting network as well as a communication network. This provides a basis for performing PVR control over a unidirectional broadcasting network and provides improved scalability. More preferably, the PVR agent program is delivered to the plurality of PVR boxes 100 through a broadcasting network. However, the present invention does not exclude the transfer of the PVR agent program by 1: 1 or 1: N transmission through a communication network.

 The PVR agent program includes at least a recording scenario execution logic processing module and a program information processing module to define a recording scenario. Perform recording scenario The logic processing module provides information about the object to be recorded. For example, it may simply be expressed as information for recording a specific program "FRIENDS". More preferably, the recording scenario execution logic processing module is associated with user information. In detail, the recording scenario execution logic processing module may be expressed as information for recording a program registered in a preferred program which is one of user information. As another example, the recording scenario execution logic processing module may be expressed as information for recording a program highly related to a program reserved for recording by the user, which is one of user information. The program information processing module provides information on a process of collecting information for recording a program. For example, when the recording scenario execution logic processing module is expressed as information for recording a program registered in a preferred program which is one of user information, the program information processing module is one of user information stored in the PVR box 100. The preference program information is checked, and the broadcasting schedule of the preference program is confirmed based on the EPG information. In other words, based on the information provided by the program information processing module, a process of collecting information for recording a program is performed.

According to a more preferred embodiment of the present invention, the PVR agent program further includes conditional execution and exception processing execution logic according to the current state and user state of the user-side PVR box. The conditional execution and exception processing execution logic processing module enables conditional and / or exception processing according to the current state and user state of the PVR box.

According to another preferred embodiment of the present invention, the PVR agent program further includes a PVR status monitor module for monitoring the status of the PVR box, and a user status monitor module for monitoring the user status. By monitoring the status of the PVR box and monitoring the user status, the reliability of conditional and / or exception handling according to the current and user status of the PVR box is improved. Conditional execution means that the agent program executes another command according to the condition. For example, the conditional execution may not perform automatic recording when the user is watching television, or delete old recordings and perform automatic recording when the storage medium (for example, hard disk) has less than one hour of storage capacity. It can be mentioned. Exception handling refers to processing of conditions issued by an agent program while executing a command. For example, the exception processing stops recording if the user turns on the power during auto recording, or deletes old recordings that the user has not watched for a long time in the background if the capacity of the storage medium remains less than 10 minutes during the auto recording. It is to secure a space.

According to another preferred embodiment of the present invention, the PVR agent program further includes a user interface display module. The user interface display module provides information for displaying information related to PVR control to a user. For example, when the current user is watching a particular program, information on how to display the information related to the PVR control is provided. Under the control of the user interface display module, various information related to the PVR control can be displayed independently on the user screen without the help of various control functions built into the PVR box. For example, under the control of the user interface display module, after collecting information necessary for recording a program is completed, a message is displayed on the PVR box to inform the user that the program is ready to be recorded and to prompt the user to perform recording. It can be displayed on the user screen without the help of various control functions. As another example, a message indicating that recording of a program is currently being performed by the PVR control of the present invention, or a message indicating that recording of a program is completed by the PVR control of the present invention may be displayed on the user screen. The PVR agent program is formed by a programming language such as Java, JavaScript, or C API.

One of the features of the PVR control method according to the invention is that the recording of the program can be performed by a combination of the recording scenario and the user information stored in the PVR box. In other words, by associating the recording scenario execution logic processing module with the user information, the recording of the program can be proceeded simply and efficiently by the combination of the recording scenario and the user information stored in the PVR box. This enables the implementation of a personalized PVR while using the PVR agent program common to all set top boxes. In other words, even though the PVR box A 100a and the PVR box B 100b receive a common PVR agent program, different programs may be recorded by differences in user information stored in the PVR box. Specifically, if the preferred program of the PVR box A 100a is program A and the preferred program of the PVR box B 100b is program B, the program personalized by the recording scenario performing logic processing module to record the preferred program is recorded. Recording is performed.

Each PVR box 100 connected to the PVR agent providing server via the network 400 comprises the following components:

i) a user input receiver 101 for receiving a reservation of a program from a user;

ii) a recording reservation management table 102 for managing a list of programs reserved by a user;

iii) a data receiver 103 for receiving data transmitted through a network;

iv) an agent program execution unit 104 for executing a PVR agent program common to all PVR boxes and defining a recording scenario of the program;

v) a processing unit 105 for controlling the processing of data transmitted through the network and the recording of a program;

vi) a recorded program management table 106 for managing a list of recorded programs based on the recording reservation table and a list of recorded programs based on recording scenarios defined in the PVR agent program;

vii) a user information database 107 which manages user information; And

viii) storing the program in storage medium 108.

Among the above components, the user input receiving unit 101, the recording reservation management table 102, and the data receiving unit 103 are the same as in the related art, and thus a detailed description thereof will be omitted.

When a PVR agent program that defines a recording scenario of a program is received through the data receiving unit 103, each PVR box 100 controls the PVR agent program under the control of the processing unit 105, and executes the agent program executing unit 104. Run under The agent program execution unit 104 may be understood as an application platform for the PVR agent program. For example, the interactive television standard platform is a Java Xlet-based application platform, a non-standard application platform such as OpenTV or NDS, a mobile-based application platform such as WiPi, an application platform such as DMBmate or DVB-H on mobile TV, ECMAScript, JavaScript and Various application platforms, such as a browser or interpreter environment, can be used as the agent program execution unit 104. At this time, the agent program execution unit 104 in the form of an application platform provides improved scalability. For example, even if the format of the agent program is changed, the format of the agent program can actively cope with the change by updating an application for executing the agent program.

The agent program execution unit 104 in the form of an application platform preferably comprises a combination of the following modules:

1. a module for receiving an agent program;

2. A module that runs an agent program under its own platform;

3. a module for collecting information necessary for recording of the program based on the recording scenario defined in the agent program;

4. A module for generating a recording command signal of the program based on the recording scenario defined in the agent program;

5. Module to control screen and channel; And

In addition to the above module, a module for receiving a control command by the user, a PVR, and modules for providing status information of the user may be further provided. If necessary, all the control for recording of the program can be performed by the agent program execution unit 104. In other words, the processing unit 105 and the agent program execution unit 104 may be implemented as one aggregation module.

By the execution of the PVR agent program by the agent program execution unit 104, various modules of the PVR agent program are activated, and the recording scenario of the program is extracted. For example, information on a process of collecting information for recording of an information program for a target to be recorded is secured. Further, the conditional execution and exception processing logic according to the current state and the user state of the PVR box, the monitoring of the state of the PVR box, the information for monitoring the user state and / or the information related to the PVR control are extracted. do.

Based on these information, information for performing recording of the program to the storage medium is collected, and by collecting information necessary for recording the program, recording of the program is performed. On the other hand, the transmission and reception of the PVR agent program and the execution of the PVR agent program proceed at least irrespective of the user's request. In other words, it is performed under the control of the PVR box 100 regardless of the user's request. It is desirable to collect the information necessary for recording the program regardless of the user's request. However, recording of a program can sometimes erode a large amount of storage media. This may cause a user's prediction error about the free space of the storage medium 108. Thus, initiation of program recording, i.e., substantial storage of the program to the storage medium 108, is preferably performed at the request of the user. To this end, according to another preferred embodiment of the present invention, after the collection of the information necessary for recording the program is completed, a message indicating that the preparation of the recording of the program is completed on the user screen and prompts the user to input the recording execution command And in response to receiving the user's recording command, starting the recording of the program to the storage medium 108. This process has the advantage of proceeding to secure the free space of the storage medium 108 of the user's actual interest by the user's intention. However, this process shows a preferred embodiment of the present invention, and the present invention does not exclude that the initiation of recording of the program to the storage medium 108 is performed irrespective of the user's request.

When the preparation of recording of the program to the storage medium 108 is completed, the recording command signal of the program is generated by the agent program execution unit 104, and under the control of the processing unit 105, the program is stored in the data receiving unit ( When received via 103, the program is stored on storage medium 108. When all recording of the program is completed, the recorded program is registered in the recorded program management table 106, and corresponding information may be displayed to the user.

The user information database 107 provides information corresponding to the inquiry of the agent program execution unit 104 when the recording scenario is related to user information. Examples of user information include user favorite channel information, channel history watched by a user, program information scheduled for recording by a user, user's e-commerce history, user's video viewing history on demand, user's viewing time pattern, user's receiving area, User age, combinations thereof, and the like.

Meanwhile, in FIG. 1, the broadcast transmission system 300 transmits various programs. In this case, the broadcast transmission system 300 may be understood as a conventional system for transmitting program content through a broadcast network. In FIG. 1, the broadcast delivery system 300 and the PVR agent providing server 200 are illustrated as separate independent entities, but this is for understanding only. If necessary, the PVR agent providing server 200 may be integrated and operated in the broadcast transmission system 300.

In the PVR control method, the system and the PVR box according to the present invention, the recording of the program may be performed by the PVR control on the server side, instead of simply recording the program by recording reservation by the user. Accordingly, the present invention further extends PVR control based on simple user input, and enables PVR control by remote control at the server side. For example,

The method according to the present invention has an effect of increasing user convenience by reducing a user's cumbersome reservation based on PVR control at a server side. For example, you can increase the utilization rate by increasing the user's viewing possibility by scheduling to automatically record a program with a high or expected audience rating. In addition, it is possible to provide an intelligent service by implementing a PVR service by personalizing a favorite program in the form of automatically recording a user's favorite program without repetitive operation based on an individual's viewing pattern or history. On the other hand, unlike on-demand video services, broadcasters can use the contents already provided for broadcasting, thereby enabling a new revenue business in the form of providing a recording reservation service without adding a content securing cost.

The present invention does not contain specific information about the user, and the same PVR agent program is delivered to all PVR boxes. This enables PVR control not only through the communication network but also through the broadcasting network. Accordingly, the present invention provides a basis for performing PVR control through a unidirectional broadcasting network, and provides improved scalability.

The present invention is based on an agent program that runs under an application platform beyond the control of an instruction or markup language based PVR. This provides a basis for actively coping with the format change of the agent program.

The present invention also does not require the delivery of user information to the server side. Therefore, the damage caused by the leakage of personal privacy information is prevented.
