Abstract

PURPOSE:To realize a room indication system valid to an efficient hotel job through the use of character picture data in the hotel CATV system. CONSTITUTION:The system is made up of a line control unit(LCU) 3 for controlling and managing the entire system, a picture control unit(PCU) 4 having a function of transmission of character picture data or the like from the LCU 3, an FSK modulator 5 to send the character picture data or the like, a memory to store th character picture data in addition to a video service function a customer room terminal equipment 10 or the like having a function of converting the character picture data into a video signal. The character picture data generated by the LCU 3 in this system are sent to each customer room terminal equipment 10 via the PCU 4 and the FSK modulator 5. The character picture data stored in the customer room terminal equipment 10 are converted into a video signal by the operation of a remote commander and displayed on a television receiver 9. The functions above are used and a room status being information of each customer room such as check-in/-check-out, end of cleaning or the like is sent as character picture data to allow each customer room to confirm a current status of all customer rooms.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hotel CATV for transmitting and receiving audio signals and video signals via a coaxial cable or the like.
The present invention relates to a CATV room indication system in system services.

[0002]

2. Description of the Related Art In recent years, along with the development of the hotel CATV system, the CATV system has been introduced into many hotels, inns, etc., and various services using the system have been provided. One of the services is CAT
It is a V-room indication system, and since it is possible to check the room status, which is information on each guest room at any time, it is useful for streamlining hotel operations. Hereinafter, an example of the system configuration of the above-mentioned conventional CATV room indication system will be described. FIG. 2 is a diagram showing an example of a system configuration of a conventional CATV room indication system. In FIG. 2, 21 is a host computer, 22 is a modem, and 23 is a line control unit (L
CU), 24 is an RF (radio frequency) modem, 25 is a multiplexer, 26 is a decoder, 27 is a head end, 28 is a cabin terminal, and 29 is a television.

In the interactive CATV system having such a configuration, the room status, which is the information of each guest room created by the LCU 23, is transmitted to the guest room terminal 28 via the multiplexer 25, the decoder 26, and the head end 27, and the television 29.
Is displayed in. Further, the room status updated by remote control operation is received by the guest room terminal 28 which also has an information input function, and then transmitted to the LCU 23 via the head end 27 and the RF modem 24 to update the room status. . The updated room status is again transmitted to the guest room terminal 28 via the above-mentioned transmission path and displayed on the television 29.

In the conventional example of the system configuration as described above, the operation is performed by two methods using the videotex image. One method is a method of transmitting a room indication display screen created by the LCU 23 and displaying the states of a plurality of guest rooms using a plurality of RF channels for each floor. Another method is LC
This is a method of transmitting a plurality of room indication display screens created in U23 for each floor while shifting the time on one RF channel. Therefore, use at least 1 RF channel for video services.
The channel had to be dedicated to the CATV room indication system.

[0005]

Therefore, in the conventional system configuration as described above, in order to introduce the CATV room indication system, some of the existing video services must be deleted or channels must be added. It had a problem that it did not become. The present invention has been made to solve such a problem, and an object thereof is to introduce a CATV room indication system without deleting a part of an existing video service or adding a channel. To do.

[0006]

In order to achieve the above object, the present invention provides a system configuration capable of character drawing services such as accounting check such as building check and quick out, in which a room status is used as character drawing data for each guest room. It is configured to be sent to the terminal and be displayed on the television by converting the character image data into a video signal in the guest room terminal.

[0007]

With the above structure, since the CATV room indication system can be introduced as one of the character drawing services, the system can be introduced without using the dedicated channel. Therefore, the system can be introduced without using the dedicated channel. it can.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A system configuration according to an embodiment of the present invention will be described below with reference to the drawings. In FIG.
1 is a host computer, 2 is a modem, 3 is a line control unit (LCU), 4 is a picture control unit (PCU), 5 is an FSK (frequency displacement) modulator, 6
Is a communication unit (CCU), 7 is an RF modem, 8 is a head end, 9 is a television, and 10 is a cabin terminal. Next, the embodiment will be described with reference to FIG.
LCU3 having a function of managing guest room terminal 10 and a function of creating character image data, PCU4 having a function of transmitting character image data from LCU3, FSK modulator 5 for modulating character image data, Consists of CCU 6 that has a control function for each guest room terminal, and a guest room terminal 10 that has a function for converting character image data into a video signal and a memory for storing character image data in addition to a video service function, and an information input function Bidirectional CATV system
The character image data of the room status, which is the information of each guest room created in 3, is sent to each guest room terminal 10 via the PCU 4 and the FSK modulator 5. The character image data accumulated in the guest room terminal 10 is converted into a video signal by the operation of the remote controller and displayed on the television 9.

When changing the status of each guest room, use the bidirectional CATV upstream transmission line,
Change data is transmitted. The room status, which is information about each guest room updated by operating the remote control, is
The information is sent back from the 10 to the LCU 3 via the head end 8, the RF modem 7, and the CCU 6, and the character image data is updated. The updated character image data is sent again to each guest room terminal 10 via the PCU 4. By using the above function, the current state of all guest rooms can be confirmed in each guest room, so that hotel operations such as maintenance of each guest room can be efficiently promoted.

[0010]

As described above, according to the present invention, since the room indication system can be introduced without using the dedicated channel, the existing video service can be partially deleted or the channel can be deleted by occupying the existing channel. No need for expansion. Further, since it is possible to deal with it only by changing the center software, it is possible to reduce the investment cost for the videotex image producing device.
