Description

Information transfer system using TV at public accommodation facility}

Conventional technology

1. Limitations of communication, signal and information transmission system between the central desk and each room in public accommodations of conventional motels, inns, etc.

In group accommodations (hereinafter referred to as motels) such as motels, hotels, inns, condominiums, and group training centers, there are large numbers of calls between the central and each room within limited areas such as extensions and local calls. He was responsible for major communication, signaling, and information delivery functions. In addition, a control box having a call function, a flashing of a plurality of lights in each room, a radio transmission and reception, a time display function, and a function of transmitting a simple signal to the center was installed in each room. In other words, between the central desk and each room, voice and simple electrical signals were all of the communication, signaling, and information transmission systems.

2. User network that uses one computer (including personal computer (WORK), WORK STATION, medium, small computer and network computer)

A user network that uses a single computer for multiple people must be equipped with at least the other input devices such as keyboard, mouse, joystick, and image display output devices such as monitor and screen, even if the main body is less than or equal to the number of each user. did. In other words, at least each user needed an input / output device to build a multi-user system for an existing computer. Therefore, if you want to configure computer network as information transfer function and user's convenience in motel, even if each room has a set of personal computers (input device, output device, computer main body, network connection network) or centralized system, Except for the computer body, other components were necessary.

An object of the present invention is to configure a communication room, a signal, information transmission system between each room and the accommodation center, and the outside of each room and the accommodation using the TV that is usually installed in the motel. The present invention constructs a network based on a central main body computer, uses a TV, a keyboard, and a mouse as an interface tool for each room user, and adds a video processing process so that the TV can be used instead of a monitor. It is a technical feature to do. This configuration reduces the high cost of constructing the information transmission network in a conventional manner, and minimizes the risk of loss of the lost room, internal parts, etc., which may occur when a monitor or a main body is installed in each room. do.

In the information age, public lodgings such as motels and inns are usually operated with dozens or even hundreds of rooms in most motels. If a personal computer is installed in each of these rooms and connected to a network, the computer cost is multiplied by the number of rooms in each room and the unit price of the computer, which increases proportionally as the number of rooms increases. Even if a high-performance central computer is used in each room with a monitor and input device for the terminal, the cost also increases arithmetically.

In general, input devices such as keyboards and mice are much cheaper than monitors or computer bodies (from one-hundreds to hundredths), making up a small fraction of the overall cost.

In addition, many motels, inns, etc. have their own networks that show customers the cable broadcasts, video programs, or programs received from satellites via TV. Of course, the network that connects each of these rooms is not only via the central desk, but generally can be controlled collectively from the central desk.

Even if there are no monitors in dozens of rooms, the following configuration can be considered in order to induce an effect such as a user using a computer system and a network for his personal use.

A schematic diagram of the invention is shown in FIG.

The present invention connects the input device group of each motel room with one or more central processing computers and builds a network using a TV as an output device. That is, as shown in the figure, a plurality of input device units are connected to a central processing computer through a network, and the information recognized and processed by the central processing computer is processed as information that can be accepted by the TV, and the output terminal of the computer is used to Allows transmission on a specific channel of the TV. In other words, if a user matches a particular television channel assigned to his or her room, a computer environment for himself is provided. In the case of transmitting an output signal to a television by using an already laid wired broadcasting network, it is configured as shown in FIG. 1. When the input network and the output network are integrated, each signal room relays all signals input and output to and from one room using a single signal integrated relay device. That is, each call room corresponds to the I / O device 1: 1, and the I / O relay device is connected to the central computer through the network.

Configuration of the input part

The input part is connected to the network by keyboard and mouse. If there is input from a keyboard or mouse in a particular room, the central computer detects the motion signal in hardware or software and connects the room to the central computer. In hardware, it uses the electrical signal sent by the switch configured as ON OFF terminal. In software, the software installed in the central computer periodically checks whether there is an input in each room. If there is no input, the connection is kept disconnected. While the connection is still active, it checks the input at a fixed time interval. If there is no input for a certain period of time, it sends a message to the user saying that the connection will be disconnected after a certain time.

Network configuration

The network uses a hub and adds an amplifier to prevent the input signal from attenuating over distance.

Role of the central computer

When the number of users is more than the number of computers

The virtual processing space inside the computer, which is the user's computer programmatic-software, is the same as the virtualization space, which is software-implemented to create the appearance of the user's personal use of his computer. Connect with 1

The computer program has the following characteristics.

User recognition unit

It recognizes the user's intention to use the network of each room or the signal of the input device, and has the uniqueness of the user-it is an attribute that distinguishes it from the user of another room and generates a unique number. This is what the central computer recognizes when the user locks the channel over a certain amount of time to a unique channel assigned to the room, or sends a keyboard input signal or a mouse input signal.

Program Internal Processing Unit

As shown in FIG. 2, a virtual screen (VIRTUAL DESKTOP) is allocated to each user by an internal program of the central computer, and each user processes his / her business in the screen of the virtual space. The internal processor separately processes each user's computer use for each user and stores the data in a storage device (hard disk or temporary storage device). The computer usage of each user is stored in a separate space of the temporary storage device, processed by the central processing unit (CPU), and sent to the image output device-TV or monitor-in units of screens of each user. That is, as shown in FIG. 3, only the contents of the content that the user is working on are output on the television screen of the user in room 3.

Channel assignment for each room

Each room user is assigned one channel of the TV channel, and the assigned number corresponds 1: 1 with the unique number of each user's room. The reason for this channel assignment is as follows.

In the video transmission network installed in the motel, the image information broadcast on any one channel can be viewed by the user when the channel is set there regardless of the room. Therefore, in personalized use such as the Internet where personality is important, if the existing video information transmission method is used as it is, confidentiality by personal use is violated. Therefore, if a unique channel is assigned to each call room and a filter or the like is provided at the connection portion of the TV receiver to selectively pass only the unique channel, the screen of each user cannot be seen by the user of the other call room.

As shown in FIG. 4, when using the existing cable broadcasting network, content supplied to a normal television is supplied with information of all channels to one television. In other words, if the user only matches the channel, all the contents supplied from the center can be used. Therefore, in this case, if a person in a room is using a computer through a specific channel, the person's work can be seen when the person in the other room is matched to a channel used by a computer entrepreneur. That is, in a typical wired broadcasting network, there is no distinction between rooms.

Therefore, in order to obtain the security of each channel while maintaining the characteristics of the wired broadcasting network and the television, as shown in FIG. 5, a frequency pass that passes only a channel that supplies normal content to the television of each room and a unique channel of the room. Inserting a filter solves the above problem.

Video processing unit inside the program

Inside the program, with the help of graphics card, video card, etc., the user uses the video information-video, video information, etc. The program processes the usage information for each user and modulates the usage information into a signal that can be accepted by the user's output device, such as a TV. The modulated signal is sent out through the output unit. Information to go to multiple users generates signals in different frequency domains for each user to correspond to filters or modulators installed in the output devices of each room, such as TVs.

Network configuration when using output device as normal computer monitor

When the network inside the motel is configured with the following network, the output unit and each call room are connected in the same manner as shown in FIG. In other words, connect a filter or other signal discrimination device between the TV input and the network to ensure personality in each room-the concept of ensuring that no other room can see a signal for a room other than its own. do.

Configuration, role and operation of filter or signal discrimination devices

Filters in each room have the function of passing through different frequency bands. The output signal from the central computer is transmitted uniformly to all rooms without distinguishing between rooms. In this case, in order for the signal for the room to be transmitted only to a specific room, the signal to the specific room should not be transmitted to another room even if the same channel is set to the same channel. To this end, a specific channel, which cannot be used in another room, is allocated to each room by 1: 1. In order to prevent the users of other rooms from seeing the information flowing through this channel, use a frequency filter to pass only signals that match the frequency-passing characteristics of the filter. You will not see the transmitted signal. To this end, the above object can be achieved by attaching a filter that passes only each call room and channel and a signal coming to this channel in a 1: 1: 1 ratio, and attaching the filter to a reception area of a television signal. Of course, this filter allows a frequency signal for a common channel, for example, a channel for over-the-air broadcasting or the like, to be used for information flowing to a common channel in any room.

Specific effects of the present invention are as follows.

First, it is possible to use the cable broadcasting supply network existing in existing motels as it is, thus reducing the high cost that is concerned when constructing a new information delivery network, and it can bring down the cost because each room uses a television instead of a monitor. have. In particular, by separately configuring the input network for transmitting signals from the keyboard and mouse, which are input devices, to the central computer, and the output network for outputting the processing results of the central computer to the television, You can create a computer-specific environment for each room.

Second, a single computer can allow several users to use computer work or the Internet. In addition to reducing the cost of installing a computer in each room according to the conventional method, it is possible to eliminate the risk of loss of the loss, internal parts, etc., which may occur when the main body and the like are installed.

Third, by installing a low-cost frequency pass filter between the TV's external signal input terminal and the input cable, it is possible to maintain the security of each room's work. Generates. In other words, the following configuration can be considered in order to induce an effect as if a user uses a computer system and a network for his personal use even without a monitor in dozens of rooms.
