How to change cable channel name of composite broadcast receiver

The present invention relates to a composite broadcast receiver, and more particularly, to a method for changing a cable channel name of a composite broadcast receiver configured to more easily change a channel name of a cable channel using a previously stored list of channel names.

In general, a satellite broadcasting method using satellites provides a broadcast signal to a wider area by using a satellite (communication satellite) located at an altitude of about tens to hundreds of kilos on the earth's surface. Ku band RF signals having a frequency band of 11.7 GHz to 12.0 GHz are used. To this end, the antenna for satellite broadcasting reception is provided with a low noise blockdown converter for converting a radio frequency (RF) signal of a very high frequency into an intermediate frequency (IF) signal, and the low noise converter converts an ultra high frequency RF signal. It converts into an IF (intermediate frequency) signal in the hundreds to thousands of MHz bands (for example, 950 MHz-2050 MHz) that can be received by a satellite broadcasting receiver (receiver).

Therefore, in the satellite broadcasting tuner provided in the satellite broadcasting receiver (receiver), the user selects and tunes a channel selected by inputting an IF signal received through a low noise converter. The satellite broadcasting receiver maximizes channel utilization, video and audio signals. Along with the improvement of quality and the ease of transmitting additional digital service data, the significant improvement of the user interface is a big advantage.

In recent years, as well as satellite broadcasting, CATV broadcasting using cable has been rapidly spreading. If a subscriber (ie, one receiver) wants to receive all of these broadcasting signals, the frequency band of each broadcasting is used. Because of this difference, a satellite tuner, a cable tuner, and a terrestrial tuner will all need to be equipped separately.

Accordingly, in order to accommodate various types of broadcasts as described above, various types of internal or external tuners may be provided, or each type of broadcast may have a separate signal processing path (that is, a satellite broadcast signal processing path and a cable broadcast signal). It may be considered that the receiver employs an integrated complex tuner for processing through a processing path, but this causes not only an unnecessary increase in hardware of the receiver itself, but also an excessive increase in the cost of the receiver. Is caused.

On the other hand, in view of the above, a composite tuner capable of simultaneously receiving satellite broadcast signals, cable broadcast signals, and terrestrial broadcast signals through a single tuning path has been developed. It is also being developed. The composite broadcast receiver controls the passband of the received signal and tunes the bandpassed signal based on the user selection signal when the satellite broadcast signal or the cable broadcast signal is received at the input side, and in accordance with the tuned signal and the user selection. Tuning the corresponding channel of the desired broadcast signal by mixing the oscillating frequencies generated, and the tuned signals are provided to corresponding demodulators through separate signal processing paths (BS path, DSR path, CATV path) respectively provided It is.

On the other hand, the satellite broadcast signal received from the composite broadcast receiver includes a variety of additional information, which includes information on each broadcast channel, that is, the channel name for each broadcasting station and program information for each channel, and predetermined by the user's request Since it is displayed as a menu screen (channel search screen), detailed information on each channel can be referred to, thus providing much convenience in selecting a user's channel.

However, since the cable broadcast signal does not include the additional information as in the satellite broadcast signal, as shown in FIG. 1, the channel search list shows CATV 001, 002, 003,... Since it is displayed on the back, there is a problem that it is difficult to grasp the characteristics of each channel.

In order to solve the above-mentioned problem, conventionally, a RENAME list is provided in a channel search screen to provide a function of arbitrarily changing a name for each cable broadcasting channel.

However, the rename function provided in the conventional channel search screen has a very troublesome problem because it is inputted one by one through a plurality of key operations in an alphabet list provided separately for inputting the name of each cable broadcasting channel.

In addition, it is not difficult to name a name suitable for the characteristics of each channel for a plurality of valid channels existing between channels 1 to 158.

Accordingly, the present invention has been made in view of the foregoing, and when a channel name of a cable broadcasting channel is changed in a channel search screen, a list of preset channel names is displayed, and if any one of the displayed channel names is selected, the selected channel name is selected. An object of the present invention is to provide a method for changing a cable channel name of a composite broadcast receiver configured to change the channel name of a cable broadcast channel by the channel name.

In order to achieve the above object, the present invention provides a method for changing the channel name of the cable broadcast to a specific name selected by a user in a channel search screen including a channel number and a channel name of each of the effective channels used in cable broadcasting and satellite broadcasting. In the channel selection mode for selecting any one of the channels displayed on the channel search screen, when the rename signal for changing the cable channel name is applied, the channel selection mode for changing the channel name for the selected channel is switched. First step; A second step of displaying a direct input request message for requesting a user to input a name to be changed when a specific channel among cable channels displayed on the channel search screen is selected in the channel name change mode; A third step of displaying a channel name list window including a plurality of preset channel names when a signal requesting a list of channel names is applied while the message is displayed; And a fourth step of changing the cable channel name selected in the second step by the channel name selected in the channel name list window when any one of the plurality of channel names displayed in the channel name list window is selected.
