Description

How to receive program content selection using digital TV receiver

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital TV receiver for receiving a digital multichannel television (hereinafter referred to as "TV") broadcast, and more particularly to a method for selectively receiving the content of a digital TV broadcast received on the multichannel.

Analog TV broadcasting, such as NTSC (National Television System Committee) TV broadcasting, was able to broadcast only one program in a frequency band of one radio frequency (RF) channel.

In contrast, the next generation of digital TV broadcasting such as HDTV (High Definition Television) has a much larger number of RF channels than analog TV broadcasting. In addition, you can flexibly allocate the necessary bit rates for the services you need when you need them. That is, it is possible to transmit a plurality of programs in a limited transmission bandwidth of one RF channel. For example, in some program schedules, it is possible to organize SD (Standard Definition) programs such as analog TV broadcasts into multiple channels, and some time zones to organize HD programs into one channel. An example of this is the United States Advanced Television System Committee (ATSC) standard. According to ATSC, it is recommended that one sub-channel of at least one HD class and six sub-SD programs can be simultaneously broadcast within one RF channel corresponding to one analog channel.

As described above, since it is possible to transmit a plurality of programs in a limited transmission bandwidth of one RF channel, a broadcaster can serve a wider variety of programs, thereby increasing the user's selection of programs.

However, the conventional broadcaster has only provided a service for transmitting different programs to the digital multi-channel. However, broadcasters may send related programs through multiple channels as needed. For example, a broadcaster is broadcasting a drama program on one of the plurality of digital channels, and the drama is produced in two contents, A and B, depending on what choice the main character makes when the contents progress. In this drama, the broadcaster broadcasts the content of A on the original channel, and the content of B is another one when the drama selects the main character while the drama is in progress. You can also broadcast by simultaneously assigning channels. Then, while watching the drama, the user can select and watch the desired content among the A content or the B content at the time of branching of the drama, and the user can receive a new broadcasting service unlike the conventional one in which the user becomes the main character and selects the content of the drama. Will be.

As described above, digital multi-channel TV broadcasting can transmit a plurality of programs in a limited transmission bandwidth of one RF channel, but a conventional broadcaster has transmitted different programs over the multi-channel and programs related to each other. According to the contents, it was not divided into several channels.

Accordingly, an object of the present invention is to provide a method for a broadcaster to simultaneously broadcast programs in which contents are related to each other, according to the contents, by simultaneously dividing the contents into several channels and allowing the user to selectively view the contents.

According to the present invention for achieving the above object, a broadcaster simultaneously transmits each content to another channel as the content of the program is diverged in the middle of a program that is broadcast on any one of digital channels, and the content of the program. It also sends data indicating that it will be forked. Then, the digital TV receiver recognizes this and displays a screen on the award hall informing the user that the contents of the program will be branched so that the user can know and select the desired contents to watch the contents of the program. It is done.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Many specific details are set forth in the following description and in the accompanying drawings to provide a more general understanding of the invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

1 is a block diagram of a high definition television (HDTV) receiver employing a moving picture expert group (MPEG) standard as an example of a digital TV receiver to which an embodiment of the present invention is applied. Referring to FIG. 1, a tuner 102 inputs a digital TV broadcast signal received through an antenna 100 to tune a channel under the control of a microcomputer 124 and an IF (Intermediate Frequency) signal according to the tune. Outputs The IF module 104 converts the IF signal output from the tuner 102 into a baseband signal. The channel decoder 106 reproduces the data bit stream by channel decoding the baseband signal output from the IF module 104. The TS (Transport Stream) decoder 108 separates audio data, video data and additional data from the data bit string reproduced by the channel decoder 106. The audio data among the separated data is applied to the audio decoder 110, decoded according to the MPEG standard or the Dolby AC-3 standard, processed by the audio processing unit and the output unit 112, and then the speaker 114 is moved. Is output through voice. The video data is applied to the video decoder 116, decoded according to the MPEG standard, and applied to the OSG (On Screen Graphic) Mixer 118 and merged with the OSG data under the control of the microcomputer 124 to process and output the video. After processing in the unit 120 is output on the screen through the water pipe 122. The OSG data is data for the microcomputer 124 to display various types of information on the screen as a graphic or a text.

In addition, a keypad 130 and an IR receiver 134 are connected to the microcomputer 124, which is a control unit of the HDTV receiver, through a user interface 128. The microcomputer 124 performs an operation according to a command input from the remote controller 132 through the keypad 130 or the IR receiver 134 according to a program stored in the memory unit 126. In addition, the memory unit 126 may include a read only memory (ROM) for storing a program of the microcomputer 124 and a random access memory (RAM) for temporarily storing data according to program execution of the microcomputer 124. And EEPROM (Electrically Erasable And Programmable ROM) for storing various reference data.

2 is a flowchart illustrating a process of selectively receiving a content of a branched program provided from a broadcaster in a digital TV receiver according to a user's selection according to an embodiment of the present invention. The operation according to the flowchart of FIG. 2 is programmed in the memory unit 126 to be performed by the microcomputer 124 of FIG. 1. In particular, according to an embodiment of the present invention, when a broadcaster reaches a branching point of a program, the broadcaster simultaneously transmits a program corresponding to the branching program to another channel, and simultaneously transmits the branched program and the original program. It will be described on the premise that data indicating that the contents of the program are forked and data containing a brief description of the contents of the diverged program are transmitted to the digital TV receiver so that the contents of the program can be diverged.

Now, embodiments of the present invention will be described in detail with reference to the above description and FIGS. 1 and 2. First, when a user is watching a drama program in which content provided from a broadcasting station diverges using a digital TV receiver, the microcomputer 124 divides the drama content from the broadcasting data of the drama program transmitted from the broadcasting station in step 200. It checks whether the meaning data is received. At this time, if the data indicating the branch of the drama content is not received, the microcomputer 124 proceeds to step 216 to the default program identification number (hereinafter referred to as ″ PID ″) assigned to the original channel. Receiving the corresponding broadcast data to display the broadcast screen according to the broadcast data to the water pipe 122.

On the contrary, when the data indicating the branch of the drama content is received in step 200, the microcomputer 124 proceeds to step 202 to receive additional information on the drama content to be branched. The additional information may be a brief description of future drama content according to a user's selection. The microcomputer 124 proceeds to step 204 and displays the additional information received in step 202 to the water pipe 122 of the HDTV receiver. FIG. 3 illustrates an example in which additional information is displayed in step 204. Referring to FIG. 3, in the case of selection 1, the main character is married, and in the case of selection 2, the main character is not married. This leads to. Accordingly, the user can view the screen of FIG. 3 displayed in step 204 and select the desired contents by key input using the keypad 130 or the remote controller 132 of the HDTV receiver. The microcomputer 124 proceeds to step 206 to check whether there is a selection key input from the user in step 204. At this time, if there is a key input for selecting the case of selection 1 or a key for selecting the case of selection 2, the microcomputer 124 proceeds to step 208 to change the PID of the current channel to the PID corresponding to the selected case. . Next, the microcomputer 124 proceeds to step 210 and receives broadcast data corresponding to the PID changed in step 208 to display the broadcast screen according to the broadcast data to the water pipe 122 of the HDTV receiver. The microcomputer 124 proceeds to step 212 and checks whether the drama program of the content selected by the user is terminated. If the drama program is finished, the microcomputer 124 proceeds to step 214. It returns to the standby state for returning and receiving the next broadcast data. In contrast, when there is no input of a program selection key from the user in step 206, the microcomputer 124 proceeds to step 216 to receive broadcast data corresponding to the default PID assigned to the original channel. The broadcast screen according to the data is displayed on the receiving tube 122.

FIG. 4 is a diagram illustrating a state in which a program started with contents common to each other according to the process of FIG. 2 is branched into various contents at various time points. As shown in FIG. 4, it can be seen that a program started with one common content is divided into four cases through a first branch point and a second branch point third branch point by a user's selection. In this way, when a user watches a program, he or she may set a situation and view contents that match the situation setting.

As described above, the present invention has the advantage of being able to watch the program more fun because the user can view the contents developed according to the situation setting while setting the desired situation when the user watches a program.
