How to display channel guide screen of composite satellite broadcasting receiving system

The present invention relates to a composite satellite broadcast receiving system capable of receiving both a satellite broadcast channel and a cable broadcast channel, and more particularly, to a method of displaying a guide screen on a broadcast channel.

The composite satellite broadcasting reception system is a system capable of receiving both general cable broadcasting and satellite broadcasting, and has the advantage of detecting a cable broadcasting signal and a satellite broadcasting signal of multiple channels through a single tuning path.

As is well known, a satellite broadcasting system is a broadcasting system capable of transmitting broadcast programs sent from ground stations through satellites located at an altitude of about tens to hundreds of kilos on the surface of the earth, and receiving them directly from the satellite receiving antennas in each home. Such a satellite broadcasting system can be largely divided into a transmitter side and a receiver side. For example, the transmitter side multiplexes M broadcast channel programs, forms a packet stream, and then transmits the packet stream on a satellite broadcast carrier. The receiving side detects the packet stream carried on the satellite broadcasting carrier, and demultiplexes only a predetermined broadcast channel program in the packet stream to serve the viewer.

Meanwhile, the cable broadcasting system transmits a general NTSC broadcast signal through a cable, and transmits each broadcast program on a predetermined cable broadcast carrier, and the receiving side detects a broadcast channel carried on the cable broadcast carrier and provides a service to the viewer. It works.

The composite satellite broadcast receiving system is a system capable of receiving both the above-described general cable broadcasting and satellite broadcasting, and has the advantage of detecting a cable broadcasting signal and a satellite broadcasting signal of a plurality of channels through one tuning path. The composite satellite broadcasting reception system has two stages of receiving process. Each of the packet streams carried on the multiple satellite broadcasting carriers is detected, and each of the detected packet streams is modulated again by QAM (Quadrature Amplitude Modulation), and then cable broadcasting. The first process is to load the QAM modulation signal on the channels remaining idle among the channels allocated for the purpose, and to transmit the cable broadcasting signal to each preset channel and then transmit it to each home through the cable. have.

The second reception process is a process performed in each home. Among the broadcast signals transmitted through the cable, only a broadcast signal of a predetermined channel is tuned and provided to the TV set. That is, when a broadcast signal of each channel is input through a cable, only a broadcast signal of a predetermined channel is detected. As described above, the broadcast signal provided through the cable is divided into a general cable broadcast signal and a digital satellite broadcast signal. have. Therefore, when the detected signal is a general cable broadcast channel, the composite satellite broadcast reception system outputs the corresponding broadcast signal as a path for processing the cable broadcast signal, and if the detected signal is a satellite broadcast channel, the broadcast signal is output as the satellite broadcast signal. Is to output the path for processing. In the composite satellite broadcasting reception system, a plurality of channels are allocated, for example, numbers 1 to 158 are allocated as cable broadcasting channels, and numbers 100 to 999 are allocated as satellite broadcasting channels. In order to allow a viewer to easily select a broadcast signal of a plurality of channels, the composite satellite broadcast reception system configures and provides guide information on a cable broadcast channel and a satellite broadcast channel as a menu screen.

1 shows such a channel guide screen. As shown in FIG. 1, the channel guide screen displays a 'menu title' at the left end of the screen, and displays a 'function item' such as channel search, channel name change, channel addition, and channel deletion at the top of the screen. The rest of the screen displays the 'channel item' for multiple channels. Here, the channel search indicated as 'function item' indicates a function of searching for each valid broadcast channel, the change of channel name indicates a function of changing channel name for an arbitrary channel, and the addition of channel adds an arbitrary channel by the user. This function allows you to set, and delete channel is the function to delete any channel.

There are separate cursors for the function items and channel items displayed on the channel guide screen.The cursors provided in the function items move to the user's desired function menu by moving left or right (channel search, channel name change, channel addition, channel deletion). ) Is selected, and the cursor provided in the channel item selects a channel desired by the user by moving up and down. At this time, the function and channel selection are performed by the user operating the key input means. For example, the user selects a desired channel by moving the cursor provided in the channel item up and down using the key input means, and then moves the cursor provided in the function item left and right using the key input means again. If you select, you will be able to perform the selected function for the selected channel.

However, in the channel guide screen as shown in FIG. 1, the function items are fixedly positioned at the top of the screen, so that the number of channel items is relatively small, and the more the channel items are displayed at the bottom of the screen, the farther from the function items, the user can easily select the items. There is a problem that can not be.

Accordingly, the present invention is to solve the above-described problems of the prior art, and when the cursor is placed on a predetermined channel of the channel item, the composite satellite broadcast reception for displaying the function item as a pop-up screen next to the channel. An object of the present invention is to provide a method for displaying a channel guide screen of a system.

In order to achieve the above object, the present invention provides a 'function item' for searching, changing, adding, and deleting a channel, and a plurality of channels in a composite satellite broadcast receiving system for selectively receiving a cable broadcast channel and a satellite broadcast channel. A channel guide screen displaying method for displaying a channel guide screen for the cable broadcasting channel and the satellite broadcasting channel configured as a 'channel item', comprising: arranging each channel of the 'channel item' in parallel on the screen; Displaying a 'function item' as a pop-up menu next to the selected channel when a predetermined channel is selected among a plurality of channels displayed in the 'channel item'; If a predetermined function is selected from the 'function items' displayed on the pop-up menu, the method includes performing the selected function on the selected channel.
