CHANNEL EDITING FUNCTION BASED ON CHANNEL ROLLING OF DIGITAL TELEVISION RECEIVER SET}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a channel editing control method of a digital television broadcasting receiver (DTV receiver), and in particular, a DTV receiver, which makes it possible to easily perform channel storage / delete / preferred channel registration using a channel rolling function. It relates to a channel editing control method of.

1 is a block diagram showing the configuration of a conventional DTV receiver, which includes a CPU 101 for DTV control, a RAM 102 and a flash ROM 103 in which data for DTV control is stored, and an AC for decoding an audio signal. -3 decoder 104, VDP 106 and VD 107 and TS 108 included in the digital broadcast signal processing unit 105 for digital broadcast signal processing, and an SDRAM in which data for the digital broadcast signal processing is stored. 109, a tuner / VSB 110 for receiving a digital broadcast signal, an analog signal processor 111 for input analog signal processing, an I ² C driver 112 for driving an I ² C bus, and the I ² C driver EEPROM 113 and EPLD 114, in which predetermined data is stored and output through the audio output, converts the audio signal output from the AC-3 decoder into an analog signal to perform volume, tone, surround control and amplification. Section 115 and a speaker 116 for audio output And a video output unit 117 for processing the video signal output from the digital broadcasting signal processing unit 105 appropriately for a display element such as a CRT or PDP, and a video output from the video output unit 117. And a display unit 118 for displaying a signal.

As the CPU, RAM, ROM, digital broadcast signal processing unit is connected via a bus (100a), and transmitting data, and various analog chips and EEPROM, EPLD as is the I ² C bus (100b) based on the I ² C protocol, Data is transmitted through.

When the user selects to perform a predetermined function such as channel tuning or device control through a user interface means such as a remote controller, the CPU 101 controls the DTV in response to a user request. Data related to the control of the CPU 101 is stored and output in the RAM 102 and the flash ROM 103, and data and commands are transferred through the bus 100a. During channel tuning, the digital broadcast signal of the channel received and tuned by the tuner / VSB 110 is input to the digital broadcast signal processor 105. The digital broadcast signal processing unit 105 is processed in the video display processor (VDP) 106, the VD 107, and the transport stream (TS) 108, and the TS 108 performs video / audio / data on the received DTV signal. The VDP 106 is in charge of processing for displaying a DTV signal, and the VD 107 displays the processed DTV video signal through a video output unit 117, such as a CRT or PDP. Supply to The audio data processed by the TS 108 is decoded by the AC-3 decoder 104 and output to the speaker 116 through the audio output unit 115.

The analog signal processor 111 is responsible for processing input analog signals, and stores and outputs data required for the CPU 101 to control various functions of the device through the I ² C driver 112 in the EEPROM 113. The EPLD 114 is responsible for data processing for signal processing in an analog chip. The CPU 101 controls all the above chips and implements a user interface through an OSD.

The DTV receiver thus formed provides a channel editing function (channel memory / delete / preferred channel registration, etc.) in the VS system. The channel editing function allows users to view and edit several channels at once. However, it is cumbersome and inconvenient because several key operations are required for storing or deleting the channel or setting the preferred channel.

2 shows an example of a general channel editing OSD screen in a DTV receiver. In Fig. 2, 201 is a current channel display window, 202 is a list of channels, 203 is a selection item such as TV, wired or DTV, 204 is a set channel position (program number), and 205 is a favorite channel or memorization / deletion. Each item related to control is shown. When using the conventional channel editing OSD screen as described above, in order to erase or store a channel in a channel editing state, and to set a preferred channel, several steps of key manipulation are required, thereby increasing inconvenience.

For example, in order to delete the stored channel TV 45, it is necessary to move to TV 45 using the up, down, left, and right arrow keys provided on the remote controller, and select erase from the moved position. This process must be repeated several times before the user can remember or delete the desired channel or set the preferred channel.

In addition, in a general analog TV receiver without a channel editing mode, it is inconvenient to perform channel storage or channel erasing by manually tuning and shifting each channel, and then operating a memory or erase key on the corresponding channel. In other words, after selecting a channel with a separate UP / DOWN key and using the UP / DOWN key, the memory / erase hotkey is toggled and selected. In this case, however, new keys must be assigned to the remote control. Therefore, a key or multiple function keys must be assigned to the remote control in a limited space so that various functions can be applied to the DTV receiver. It is not efficient with current DTV receivers.

That is, the channel memory or erase function using a shortcut key used in an existing analog TV receiver can also move a channel (tuning operation) to each channel, and then use a memory or erase key to store a specific channel while the channel is tuned. This is the same as the inconvenience of having to operate or erase the data, and in the light of the diverse and complicated functions of the video receiver, it is necessary to assign a new key to the remote control according to the new function. Difficult to use and inefficient.

An object of the present invention is to provide a method for controlling channel editing of a digital television broadcast receiver, which enables faster and easier channel editing in a DTV receiver.

It is still another object of the present invention to provide a channel editing control method of a digital television broadcasting receiver, which makes it possible to quickly and easily perform channel memory / clear / preferred channel registration (setting) by using a rolling function when editing a channel in a DTV receiver. It is.

Still another object of the present invention is a method of controlling channel editing of a digital television broadcasting receiver, which enables easy channel editing through a rolling function using an existing remote control key without assigning a separate shortcut key when editing a channel in a DTV receiver.

The channel editing control method of the digital television broadcasting receiver according to the present invention comprises the steps of selecting and setting the type of the channel to be rolled and the rolling time in advance according to a user's request, and the channel and the channel sequentially. A channel rolling step of displaying a tuned image of a corresponding channel, and a channel editing step of editing a corresponding channel in response to an edit item selected by a user while the channel is displayed in the channel rolling step. That is, it implements a rolling function in which the channel is automatically switched at a predetermined set time in the channel editing state, and editing (memory / erase / preferred channel) for the corresponding channel by simply operating a promised key during channel rolling. Registration).

In addition, the present invention implements a rolling function in which a channel is automatically switched at a predetermined time period in a channel edit state, so that the rolled channel is rolled over the entire channel, the rolled for the memorized channel, and the memorized channel. Another feature of the present invention is that it is possible to maximize user convenience when editing a channel using the rolling function.

The present invention also provides a remote control key by controlling the selection of the channel rolling function, the rolling time, or the type of channel to be rolled in the channel edit state so that the keys already assigned to the remote controller can be used without additional new key assignment. Another feature is to maximize the ease and efficiency of assignment and operation.

According to the channel editing control method of the digital television broadcasting receiver according to the characteristics of the present invention, in the existing channel editing state, the cursor moves to the desired channel and moves to the desired channel in order to store / delete / register the preferred channel. It solves the inconvenience of performing channel memory / delete / preferred channel registration with specific key, eliminates the assignment of shortcut key for channel memory / delete in existing analog TV, solves the complexity of remote controller and enables efficient key management. do.

In the channel editing control method of the digital television broadcasting receiver according to the aspect of the present invention, the channel rolling is a function of displaying the channel so that the user can view the corresponding channel for the set channel rolling time, and moving to the next channel after the set channel rolling time has elapsed. Is defined. In this way, the channel is automatically switched based on the predetermined time period, so that the user can view the information of several channels at once without several key operations, and the channel rolling time can be adjusted and set by the user. The minimum time required must be ensured and the user can select the type of channel to be rolled up to increase convenience.

FIG. 3A is a flowchart illustrating a method for allocating a channel edit key according to the present invention, and shows that a new special key is assigned to a specific channel existing based on channel rolling. That is, in the case where the determination result of the step 300 is the channel edit screen in the CPU 101, the channel edit screen OSD is executed (step 300a), and a new special key for channel editing is assigned to a specific key on the existing remote controller. (Step 300b, 300c), in the normal normal state instead of channel editing, the original function of the existing key is used as it is (step 300d, 300e).

3B is a flowchart showing an embodiment of a channel editing control method of the digital television broadcasting receiver of the present invention.

Step 301 is a step of entering a channel edit mode. In the channel editing mode, the OSD screen may be displayed as shown in FIG. In FIG. 4, 401 is a current channel display window, 402 is a preferred channel list, 403 is a selection item such as TV, wired or DTV, and 404 is a set channel position (program number).

405 is an item corresponding to a menu key of the remote controller. When the menu key on the remote controller is pressed in the channel edit mode, the user exits the channel edit mode and returns to the initial menu state where channel editing is set. 4 illustrates an example in which a new special key is allocated to an existing specific key in the channel editing key as described in FIG. 3A. The specific key (for example, TV / external input key and screen size) shown in FIG. Key, etc.) is merely an exemplary embodiment provided to assist in understanding and explanation of the present invention, and the key described and expressed herein is not limited to the "special key newly assigned to an existing key as a channel edit key" of the present invention. .

406a corresponds to the TV / external input key of the remote control. When the channel is in the edit state, it operates as a key for executing “channel rolling.” 406b corresponds to the screen size key of the remote control. It operates as a key to execute “Channel Rolling Setup”. The 406c corresponds to the Save / Erase key of the remote controller. If this item (key) is selected during channel rolling, the channel being rolled is memorized (or toggled to erase). give. 406d corresponds to a favorite channel key of the remote controller and, in the channel editing state, registers the rolling channel as a "preferred channel".

Therefore, in the present invention, a separate key assignment for using the channel rolling function is not required, and it is possible to exit the channel edit mode by using the "menu key" previously assigned to the remote controller, and to " Channel Rolling can be performed using the TV / External Keys, and Channel Rolling Settings can be executed using the “Screen Size Key” assigned to the remote control, and “Remember / Clear” is assigned to the remote control. The key "can be used to remember and delete the channel while rolling, and the favorite channel can be registered during the channel rolling by using the" preferred channel key "which has been previously reached on the remote controller.

In the channel editing mode according to the present invention, with the execution of the rolling function, it is possible to set in advance what kind of channel to perform rolling and how much to reduce the rolling time (interval). That is, when the user presses the "screen size" key of the remote control in the channel editing OSD screen as shown in FIG. 4, the channel rolling setting is selected (step 302). The channel rolling setting is divided into a channel rolling mode and a rolling time setting mode for selecting which channel to roll. 5 shows an OSD screen when the channel rolling setting is selected, and 501 shows the channel rolling setting OSD. The channel rolling setting OSD 501 includes a channel rolling selection window 501a and a channel rolling time setting window 501b for selecting the type of channel to be rolled.

6 shows an example of a menu state that appears when the channel rolling setting is selected. 601 is a case of selecting to roll on all channels, 602 is a case of selecting to roll on a memorized channel, and 603 is a case of setting to roll on an unmemored channel. , 604 designates a rolling time, which exemplifies a case where the rolling time of all channels is set.

The rolling time can be set by increasing or decreasing it at a predetermined time, for example, at 1 second intervals by pressing a specific key, and selecting one type of time that can be set, for example, within 1 to 5 seconds. You can also set it.

In step 303, the user selects one item from the setting of channel rolling or channel rolling time from the OSD screen. Step 304 and step 305 is a step of setting what kind of channel the user wants to roll and the rolling time using the OSD screen as shown in FIG. In other words, it is selected whether to select rolling of all channels, rolling of stored channels, or rolling of unsaved channels, and setting rolling time for each case.

Thus, "channel rolling" is selected by selecting the channel to be rolled and setting the rolling time, and selecting "TV / external input key" on the channel editing OSD screen of FIG.

That is, in step 306, " channel rolling " is selected. When channel rolling is selected in this way, the channel rolling is performed for the corresponding channel using the information selected and set previously (the channel to be rolled and its rolling time). The channel rolling may be performed by a DTV receiver control unit (CPU or microcomputer) by sequentially tuning the tuner using the channel information to be rolled and displaying the channel only for a set rolling time, and then skips to the next channel. .

As shown in FIG. 4, the channel is displayed on the display window 401 for a predetermined rolling time. For example, if you roll a memorized channel at two-second intervals, the display window 401 will display the memorized channels in turn at a two-second interval, and then display the channel position 404 at the displayed "remembered channel." It will move automatically. In the same way, rolling over the entire channel or for an unmemored channel can also take place.

In this way, when a channel is displayed, i.e., when a particular channel is displayed during the set time, the user can determine whether to memorize the channel, delete it, or register it as a favorite channel. / Delete / Preferred Channel registration is made (step 308). In other words, while channel rolling is in progress, the user can select the memory / clear or favorite channel for simple setting. Also, when editing a channel using channel rolling, the user can change the existing channel without assigning a new remote control key. Keys that are used for other functions other than editing can be used as they are, so that the keys can be used efficiently.

Editing control using the channel rolling function described so far is performed by the CPU-microcom in the DTV receiver of FIG. 1 described above, and the OSD processing may be performed using a microcomputer equipped with an OSD function, although the OSD processing may be performed separately. It may be. Although not shown in FIG. 1, a technology related to remote control (transmitter) and reception (reception) and decoding of a remote control signal for controlling a device by a CPU may be easily implemented in the art based on a known technology. Detailed descriptions and explanations thereof are omitted.

The present invention has the convenience of performing channel editing (memory / erase / preferred channel registration) in a DTV receiver with only a simple key operation. In addition, the memory / erase function using the shortcut key used in the conventional analog TV has to be assigned a separate shortcut key to the remote controller for implementation, but in the present invention, the existing key is assigned to the channel in the channel edit mode without assigning a separate key. It can be used as a key for rolling and setting, increasing the efficiency of using the remote control keys.

The channel editing control method based on the channel rolling function of the present invention is suitable for a multifunctional, multi-channel digital TV, and can easily perform channel editing with a simple operation, and also shorten the channel editing time.
