The mobile phone 3000 transmits the authentication information to the broadcast signal receiving apparatus 200 corresponding to the unique ID. At this time, sending the authentication information to the broadcast signal receiving apparatus 200 for information security may include a user confirmation procedure. If the broadcast signal receiving apparatus 200 is fixed, the mobile phone 3000 can check only the ID and automatically transmit authentication information.

In another implementation method, the broadcast reception device 200 transmits information about an IPTV broadcast server, its own ID, and a program to the mobile phone 3000, and the mobile phone 3000 transmits the information to the IPTV broadcast server 2000. Request authentication for the program to receive authentication information. The mobile phone 3000 transmits the received authentication information to the broadcast receiving device 200, and the broadcast receiving device 200 receives and displays the program using the received authentication information. On the other hand, the charging method of the broadcast signal receiving apparatus 200 similarly, the mobile phone 3000 pays a predetermined cost, and receives the information about it from the IPTV broadcast server 2000. When the charging information is input to the broadcast signal receiving apparatus 200 through an input device such as a remote controller 300, the broadcasting signal receiving control unit 260 transmits the charging information to the IPTV broadcasting server 2000. The broadcast server 2000 may download broadcast programs corresponding to the corresponding billing information to the broadcast signal receiving apparatus 200. In this case as well, the user's convenience can be increased by providing a communication means between the mobile phone 3000 and the broadcast signal receiving apparatus 200.

Can also be used.

4 is a flowchart illustrating a broadcast program receiving method according to a user's selection according to an embodiment of the present invention.

Hereinafter, a description will be given with reference to FIGS. 1 to 4.

4 illustrates a method of selecting a program to be viewed using a computer and reproducing the selected program in the broadcast signal receiving apparatus 200 synchronized with the program. First, the user selects a program to be viewed through the computer 100 (S410).

In operation S420, the computer 100 transmits information about the corresponding program to the broadcast signal receiving apparatus 200 capable of receiving the program. As mentioned above, the information about the program may include not only information about the program itself but also storage location information (eg, URL information) of the program that can download the program. The computer transmits this information to the broadcast receiving apparatus to be watched. In other words, the computer and the broadcast receiving apparatus must share information with each other in advance.

The broadcast signal receiving apparatus 200 transmits a request signal of a broadcast program to a predetermined broadcast server 2000 so as to download the selected program (S430).

If authentication is required for the selected program, the broadcast server 2000 performs a user authentication procedure for whether the corresponding broadcast signal receiving apparatus 200 can download the program before transmitting the program according to the request signal of the corresponding program. To perform. The user authentication procedure may be performed by the broadcast signal receiving apparatus 200 itself or may be performed through the user's mobile phone 3000 using the broadcast signal receiving apparatus 200.

If the user can download the program as a result of performing the user authentication procedure, or if the program can be downloaded without the user authentication procedure, the broadcast server 2000 broadcasts the selected program to the broadcast signal receiving apparatus 200. In step S440, the broadcast signal reception apparatus 200 receives the broadcast signal. In this case, the program transmitted by the broadcast server 2000 may be a high quality / high definition program such as an HD class program.

The program received by the broadcast signal receiving apparatus 200 is reproduced after being decoded through a predetermined decoding process in the broadcast signal receiving apparatus 200 (S450).

A description will now be given of the case of implementing the present embodiment with reference to FIG. 10. When a broadcast signal receiver or an audio device is connected to a computer used at home through the Internet or a home network, and the user selects audio to be listened to or video to watch through the computer, the computer is connected to the program. Information is transmitted to the audio device or the broadcast signal receiving apparatus, and the audio device or the broadcast signal receiving apparatus reproduces a program desired by the user using the corresponding information. Of course, the computer can play the video in the silent state. For example, if a user selects and plays a desired program in a UCC program capable of viewing UCC (user created contents), the UCC program downloads the program and simultaneously transmits information about the program to the audio device or the broadcast signal receiving device. The audio device or the broadcast signal receiving apparatus requests the corresponding program to the server storing the UCC using the corresponding information, and receives the program according to the request and plays the desired program (FIG. 10). Such a reproduction method may provide high quality audio and video through a professional audio device or a broadcast signal receiver 200 if a program can be easily searched using a computer. The advantage of this method is that there are no changes to the server. From the server's point of view, there are two requests for the same program, and data is sent for each request.

5A and 5B illustrate screens provided to a user for selecting a broadcast program according to an embodiment of the present invention. If the number of cable channels is limited and there are many programs to be provided, a plurality of programs can be included in one channel of the cable and transmitted.

According to an embodiment of the present invention, various user interfaces from which the user can select a broadcast program are received and provided from the cable broadcast server 1000.

In the embodiment of FIG. 5A, two broadcast programs are included in one channel, and two broadcast programs 252-1 and 252-2 are provided to the display 252 as one screen. have. In this case, an audio signal for each broadcast program may be transmitted using left and right channels of stereo channels, respectively. In other words, two programs are reduced and transmitted on one channel, and the audio signal is converted into a mono signal and transmitted using each channel of stereo. In reproduction, the audio signal may be provided to the user through the corresponding left and right speakers 254-1 and 254-2. That is, the audio signal of the broadcast program for the left screen 252-1 is output from the left speaker 254-1, and the audio signal of the broadcast program for the right screen 252-2 is output from the right speaker 254-2. Is output. Alternatively, two audio signals may be summed and output to both speakers. Of course, the user may be provided with a means for selecting one screen through highlights, etc., to output only the audio of the selected channel. 5 (b) shows an example of transmitting four programs on one cable by reducing the video size to 1/4. In this case, only two audio signals can be sent. However, if the cable TV supports 5.1 channels, four audio signals can be sent. The broadcast signal receiving apparatus 200 may simultaneously show four channels, or may enlarge each program one by one. This way, if you can show multiple programs on one channel, you can take full advantage of the advantages of cable TV, which has fast channel switching. When the channel is selected, the broadcast signal receiving apparatus 200 transmits the information about the selected program to the high quality server as described above, and starts to play when the channel is received. Of course, you can send 9, 16, etc. programs on one channel to send more programs.

Meanwhile, according to an exemplary embodiment of the present invention, the left and right broadcast programs 254-1 and 254-2 may be implemented to be selectable through the remote controller 300. The user may select one of the left and right broadcast programs 254-1 and 254-2. In this case, audio of two broadcast programs is transmitted as mono audio using a stereo channel, and the broadcast signal receiving apparatus 200 may reproduce audio of a program selected by a user in mono. In this case, the selected broadcast program is initially provided with a low quality / low quality broadcast program such as SD video (via cable broadcasting, terrestrial broadcasting, satellite broadcasting, etc.), and then through an external network or a personal storage medium such as the Internet. After downloading the high quality / high definition broadcasting program, the user can provide the program.

Meanwhile, in the embodiment of FIG. 5 (b), four broadcast programs 252-3, 252-4, 252-5, and 252-6 are provided on one channel so that a user can select one of them. It provides an interface. In this case, four broadcast programs are displayed on the display 252, and the user can select one of these broadcast programs through the remote controller 300. As in the description of FIG. 5A, an exemplary embodiment may be considered in which a low quality / low quality broadcast program is initially provided to a selected broadcast program and then provided to a user after downloading a high quality / high quality broadcast program. In this case, when 5.1 channels are provided, audio can be transmitted as mono audio, and when only stereo can be transmitted, four mono channels can be transmitted to one stereo channel through frequency division. That is, it is possible to reduce the bandwidth to a low pass filter on four mono channels first, modulate one channel, and then send two channels with the reduced bandwidth to one channel. .

In this manner, it is also necessary to transmit the currently displayed frame index information to the high quality broadcasting server. As described above, the frame index of the program is displayed by using a closed caption or the like in the middle of the program, and the broadcast signal receiving apparatus 200 transmits this information to the high quality broadcast server.

In general, in a multimedia transmission using a communication network, when a user selects a new channel, the broadcast signal receiving apparatus 200 requests a selection channel from a broadcast server and receives data on the broadcast server as in IPTV. When a certain amount of data is received in the buffer of the broadcast signal receiving apparatus 200, playback starts. In such a system, a delay occurs after receiving a channel conversion to receive data, and in particular, an additional delay may occur because a digital method requires waiting for an I frame. In order to solve such a problem, when the high speed channel conversion broadcast program server transmits a plurality of channels to the high speed channel switching channel as shown in FIG. 5B, the broadcast signal receiving apparatus 200 may enlarge and display them. That is, when the user requests channel conversion, the broadcast signal receiving apparatus 200 extracts and enlarges the corresponding screen from the high speed channel switching channel and requests the broadcast server for high resolution channel data. When receiving the channel data of the high resolution, the broadcast signal receiving apparatus reproduces it. As another method for fast channel conversion, the fast channel conversion broadcast program server can be configured to narrow the I frame interval, transmit data compressed at low resolution / low quality, and transmit high resolution / high quality data.

6 is a flowchart illustrating a method of providing an HD broadcast program according to an embodiment of the present invention.

Hereinafter, a description will be given with reference to FIGS. 1 to 6.

The broadcast signal receiving apparatus 200 tunes the cable broadcast channel to receive the broadcast signal for the corresponding channel (S610).

The program is downloaded and provided to the user through the tuned cable broadcasting channel (S620).

* On the other hand, the broadcast signal receiving apparatus 200 is a broadcast server that can download a broadcast program through a cable broadcast channel and is currently connected to the broadcast signal receiving apparatus 200 to download a corresponding broadcast program of high quality / high definition (2000). ). Based on the search result, the broadcast server 2000 requests a high quality / high definition broadcast program such as HD level (S630).

The user selects a broadcast program that the user wants to watch in the broadcast signal receiving apparatus 200 capable of receiving cable broadcasting. In this case, selection of a broadcast program may be performed by changing a channel (S640).

As mentioned above, cable broadcasting is only an embodiment, and instead of cable broadcasting, terrestrial broadcasting, satellite broadcasting, and a broadcast program server capable of high-speed channel conversion may be applied. In this embodiment, analog cable broadcasting, analog terrestrial broadcasting, analog satellite broadcasting, and broadcasting capable of high-speed channel conversion (including both digital and analog methods) have low quality / low Zapping time while changing channel time. It has a property of providing a low quality broadcast signal, and IPTV broadcasting is based on the premise that it has a disadvantage in that it takes time to download data while providing a high quality / high quality broadcast signal.

If there is no channel change, a high quality / high definition broadcast program is received according to the high quality / high definition broadcast program request in step S630 (S650). The low quality / low quality cable broadcast program currently being provided is replaced with the received high quality / high quality broadcast program and then provided to the user (S660). In general, steps S610, S620, and S630 are performed in a short time, but step S650 may take time. Since the user may perform channel conversion after step S630, the broadcast signal receiving apparatus 200 should continuously check whether the channel is changed. If a user makes a channel change request while waiting to receive high quality / high definition broadcast data, it processes it.

7 is a view for explaining the function of the remote control according to an embodiment of the present invention. 8 is a view for explaining an electronic program guide according to an embodiment of the present invention.

Hereinafter, a new broadcast program selection method or a new broadcast channel selection method will be described with reference to FIGS. 7 and 8.

A large number of programs in countries around the world are available for IPTV. It is very important to provide a large number of channels efficiently and to allow a user to easily access arbitrary programs with a remote controller. In the present invention, to solve this problem, as shown in Figure 7, the remote controller 300 of the present embodiment adds a new function to the existing remote control function. In the present exemplary embodiment, a 'CH 1' key 312 for selecting a country where a broadcast program is manufactured as a first segment, a 'CH 2' key 314 for selecting a genre of a broadcast program as a second segment, and a third In addition, a 'CH 3' key 316 for selecting a type of a specific broadcast program in the corresponding genre of the broadcast program is added.

Using the remote controller 300 of FIG. 7, a specific broadcast program that a user wants to watch on an IPTV such as the electronic program guide 700 of FIG. 8 is selected.

The electronic program guide 700 according to the present embodiment includes a country section 710, a genre section 720, and a kind section 730.

For example, the 'CH 1' key 312 is used to select 'Country 1' in the country section 710, and the 'CH 2' key 314 is used to select 'Sports',' Select 'movie', 'news', 'drama', 'shopping', etc. and select a specific program using the 'CH 3' key 316, and when the selected program is received, the display of the broadcast signal receiving apparatus 200 ( 252). At this time, the broadcast signal receiving apparatus 200 continues to play the program as in the normal broadcast. That is, when country A is currently selected, the genre is a movie, and the channel is number 10, when the user operates the country channel 'CH 1' key 312, when the user moves to the next country, the broadcast signal receiving apparatus 200 is B. Shows the national film genre channel 10. If there is no corresponding genre or channel number, the adjacent genre or channel number may be shown.

In another implementation, when the user selects the 'movie' genre in the genre section 720 through the 'CH 2' key 314 of the remote controller 300, a movie broadcast program that can be selected by the current user in the 'movie' genre Types 'movie 1', 'movie 2', and 'movie 3' are displayed on the display 252 of the broadcast signal receiving apparatus 200, and the user finally controls the 'movie 1' in the category section 730. If selected through the 'CH 3' key 316 of (300), the information about this is from the second broadcast signal receiver communication unit 320 of the remote controller 300 of the remote control communication unit 220 of the broadcast signal receiver 200 Is sent.

Then, the broadcast signal receiver controller 260 tunes a channel so that the cable broadcast server 1000 can receive the corresponding broadcast program based on the information from the remote controller 300, or broadcasts the broadcast to the IPTV broadcast server 2000. Generate a signal requesting a program and send it. In this case, as described above, the low-quality broadcast program initially received from the cable broadcast server 1000 is provided, and when a high-definition version of the broadcast program is later downloaded from the IPTV broadcast server 2000, it is provided to the user. Embodiments may be considered.

In the above example, the country is taken as the first classification, but since a plurality of languages may be used in one country or the same language may be used in multiple countries, a language, continent or region may be used instead of the country as the first classification. Of course. Of course, you can use a different sorting scheme instead of genre as a second category, and add additional up / down keys for further sorting.

In another embodiment, a program is illustrated as shown in FIG. 8, and a desired channel can be selected through the above-described three channel change keys. In the present embodiment, for example, highlighting is performed on the country, genre, and type selected on the electronic program guide 700 through the remote controller 300.
