In order to achieve the above object of the present invention, a broadcast signal receiver for an analog broadcast signal and a digital broadcast signal includes: an input unit for key input of a user; A display unit; A digital broadcast signal processor for receiving and processing a digital broadcast signal and outputting a first video signal; An analog broadcast signal processor for receiving and processing an analog broadcast signal and outputting a second video signal; And processing the first and second video signals and the digital and analog channel list data so as to be displayed together through the display unit. And a picture structure and a control unit for controlling the digital broadcast signal processing unit and the analog broadcast signal processing unit such that a video signal of a specific channel designated by the display unit is displayed through the display unit.

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

1, a broadcast signal receiver according to an embodiment of the present invention includes a digital broadcast signal processor 10, an analog broadcast signal processor 14, an image configuration and controller 19, a display unit 20, and an input device ( 23). The digital broadcast signal processor 10 is for receiving and processing digital broadcast signals, and includes a digital tuner 11 and a digital broadcast signal processor 13. The analog broadcast signal processor 14 is for receiving and processing analog broadcast signals, and includes an analog tuner 15 and an analog broadcast signal processor 17. The image configuration and control unit 19 processes the video signals output from the digital broadcast signal processor 13 and the analog broadcast signal processor 17 to be displayed on the display unit 20. The image configuration and control unit 19 also controls the operations of the digital broadcast signal processing unit 10 and the analog broadcast signal processing unit 14 according to the key input signal generated from the input unit 23 by the user's key input.

The broadcast signal receiver of FIG. 1 having such a configuration will be described with reference to FIG. 2.

The digital tuner 11 of the digital broadcast signal processor 10 selects a digital broadcast signal of a specific channel according to the image configuration and the control of the controller 19 and supplies the selected broadcast signal to the digital broadcast signal processor 13. The digital broadcast signal processor 13 extracts a transport stream from the digital broadcast signal supplied from the digital tuner 11, and outputs a video signal of a specific program included in the extracted transport stream to an image configuration and control unit ( 19) For convenience of description, the video signal obtained from the digital broadcast signal of the currently selected channel is designated as the 'first video signal', and the video signal obtained from the currently selected analog broadcast signal is designated as the 'second video signal'. A digital broadcast signal, which is currently provided or will be provided in the future, contains a multi-program transport stream or a single program transport stream in which several programs are multiplexed. In this case, the above-described first video signal is a video signal representing a single program. The digital broadcast signal processor 13 prepares a digital channel list for the digital broadcast channels that can be received using a packet identifier (PID) included in the transport stream. Then, the data of the created digital channel list is supplied to the image structure and control unit 19.

On the other hand, the analog tuner 15 of the analog broadcast signal processor 14 supplies the analog broadcast signal of a specific channel to the analog broadcast signal processor 17 according to the image structure and the control of the controller 19. The analog broadcast signal processor 17 performs signal processing on the analog broadcast signal, and supplies the resulting second video signal to the image structure and control unit 19. The analog broadcast signal processor 17 prepares an analog channel list related to analog broadcast signals that can be received through the analog tuner 15. Then, the data of the created analog channel list is supplied to the image structure and control unit 19.

The picture structure and control unit 19 stores the data of the integrated channel list for all broadcast channels received by the digital tuner 11 and the analog tuner 15. When there is a user's request through the input unit 23, the image configuration and control unit 19 displays the stored integrated channel list data through the display unit 20 such as a CRT.

In order to display the first and second video signals of the currently selected digital and analog channels together, the image configuration and control unit 19 divides the entire screen of the display unit 20, the first video signal on the left side and the right side. Displays second video signals respectively. Alternatively, the picture structure and control unit 19 displays the first and second video signals in a picture-in-picture manner. In this case, when the first video signal becomes the mother screen, the second video signal becomes the child screen. The reverse is also possible. The picture structure and control unit 19 also displays the data of the stored integrated channel list together with the first and second video signals of the currently selected digital and analog channels. At this time, the unified channel list is displayed opaquely or semi-transparently. The integrated channel list displayed opaquely completely masks the pictures displayed by the first and second video signals. Therefore, there is an advantage that the user can see the unified channel list clearly. The integrated channel list displayed semi-transparently has an advantage of allowing the combined channel list and pictures by video signals to be viewed together. An example of the integrated channel list expressed through the display unit 20 is shown in FIG. 2. The unified channel list is composed of a list of digital channels and a list of analog channels, as shown in FIG. Each channel list has broadcaster names DCH1, DCH2, ..., ACH1, ACH2, ....

When the video signals and the integrated channel list are displayed together, the image configuration and the controller 19 displays a position indicator such as a cursor or a pointer through the display unit 20. When the user operates the input unit 23 to move the displayed position indicator, the image configuration and control unit 19 displays the digital broadcast signal in order to display the video signal of the specific broadcast channel indicated by the position indicator on the integrated channel list. The operation of the processor 10 or the analog broadcast signal processor 14 is controlled. For example, when the digital channel DCH2 is indicated by the position indicator, the picture structure and control unit 19 controls the digital broadcast signal processing unit 10 to display the video signal of the digital channel DCH2. At this time, the digital broadcast signal processor 10 controls the digital tuner 11 to change the current packet identifier (PID) value so as to select a video signal of another program or change the currently selected channel to another digital channel. As a result, the newly selected first video signal is transmitted to the picture structure and the control unit 19. When the user manipulates the input device 23 to finally determine a specific channel, the image configuration and control unit 19 displays the video signal of the finally determined channel on the entire screen of the display unit 20.

As described above, the broadcast signal receiver according to the present invention provides an integrated channel list of all digital channels and analog channels capable of receiving broadcast signals. Whenever the location indicator points to a specific channel on the integrated channel list, the video signal of the broadcast channel is displayed. Thus, the present invention provides the effect of allowing the user to easily and within a short time view the entire channels receivable by the broadcast signal receiver.
