ABSTRACT:
DESCRIPTION
1. Technical Field
The present invention relates to a multimedia data system and the method for providing the public with useful information, such as news, the weather forecast, traffic information, culture news, information for stock market, sports news, and a campaign for the public good, through a radio paging network, and for broadcasting stopping-places and transit areas and giving various kinds of information through both moving picture and still picture system.
2. Background Art
FIG. 1
is a block diagram illustrating a conventional character radio paging network, in which the reference numeral
11
denotes an information provider,
12
a radio paging character server,
13
a radio paging exchange station,
14
a radio paging base station, and
15
a character radio pager.
As shown in
FIG. 1
, the conventional character radio paging network includes: the information provider
11
which furnishes the public with useful information, such as news, weather forecast, traffic information, culture news, the information for stock market, sports news and a campaign for the public good; the radio paging character server
12
which receives information from the information provider
11
and then classifies them according to subscribers; the radio paging exchange station
13
which converts the classified information data from the radio paging character server
12
into transmission data which the character radio pager
15
can receive; the radio paging base station
14
which broadcasts the data inputted from the radio paging exchange station
13
; and a character radio pager
15
which provides the public with information data transmitted from the radio paging base station
14
.
FIG. 2
is a block diagram illustrating a conventional character radio pager in
FIG. 1
, in which there are shown a receiving antenna
21
, a distributer
22
, a receiving unit
23
, a frequency synthesizer
24
, a data processing unit
25
, and a character indicator
26
.
In the distributer
22
, the character radio frequency received from the receiving antenna
21
is distributed to the receiving unit
23
and the frequency synthesizer
24
. The frequency synthesizer
24
outputs a control signal for the receiving unit
23
to select a fixed channel. The receiving unit
23
demodulates the signal from the distributer
22
, in response to the control signal of the frequency synthesizer
24
. The data processing unit
25
outputs character-based information to user from the character indicator
25
by processing the output from the receiving unit
23
.
In accordance with the illustrated conventional character-based radio paging network, there is a difficulty in securing a majority of customers on the view of network operator, thereby causing the profit to be diminished, and there is a hindrance in effectively using the limited frequency resources.
Therefore, it is necessary to create a new service for variously using the character-based radio paging network. Meanwhile, in the case that the driver directly fabricates an announcement about bus stop database through the operation by his hand, there is a problem making him be inattentive while driving, thereby threatening the passenger's safety.
DISCLOSURE OF INVENTION
An object of the invention is to provide a multimedia data service system and a method for proving the public with useful information such as news, the weather forecast, traffic information, culture information, the news for stock market, sports news, the campaign for the public good, etc. through the radio paging network by establishing multimedia terminal system. Thereby, the service of public transport can be surely improved by furnishing with both moving and still picture. In such a case, this invention is employed for a driver to be stopped from being inattentive while driving, thereby considering passengers' discomfort. Also, at the same time, the passenger's safety is provided by broadcasting the bus stop announcement through the received information from GPS receiver.
In accordance with an aspect of the present invention, there is provided a system for providing character-based information for a moving object, the system comprising: a first receiving means for receiving and demodulating position information indicating a present position thereof; a second receiving means for receiving and demodulating control information and character information from a character radio paging network providing the character-based information; a first store means for storing the character-based information received from the second receiving means; a second store means for storing the control signals received from the second receiving means and operator information directly inputted by an operator; a third store means for storing the position information according the movement of the moving object; a forth store means for storing an announcement for the present moving position of the moving object; a control means for extracting useful information from the first and second store means or extracting an announcement stored in the forth store means under the control of a scheduler in case where the position information received from the first receiving means is consistent with the position information stored in the third store means; an output means for outputting the information of the first, second and forth store means; and a remote control means for transmitting control signals to the second receiving means through the character radio paging network in order to remotely manage the information stored in the second store means.
In accordance with another aspect of the present invention, there is provided a system for providing character-based information for a moving object, the system comprising: a receiving means for receiving. and demodulating control information and character information from a character radio paging network providing the character-based information; a first store means for storing the character-based information received from the receiving means; a second store means for storing the control signals received from the receiving means and operator information directly inputted by an operator; a control means for extracting useful information from the first and second store means under the control of a scheduler; an output means for outputting the extracted information from the first and second store means; and a remote control means for transmitting control signals to the receiving means through the character radio paging network in order to remotely manage the information stored in the second store means.
In accordance with further aspect of the present invention, there is provided a method for providing useful information including character-based information for a moving object, the method comprising the steps of: storing operator information directly inputted by an operator, position information associated with a movement of a moving object, and announcement information for broadcasting a present moving position of the moving object, in a database; transmitting control information for the operator to manage the information stored in the database and character-based information through a character radio paging network; receiving control information and character-based information through the character radio paging network and storing the received control and character-based information in the database; receiving and demodulating present position information of the moving object; and extracting and outputting the operator information directly inputted by the operator or the character-based information, or extracting and outputting the announcement corresponding to the present position of the moving object in case where the present position of the moving object is consistent with moving object's position information stored in the database.
In accordance with still further aspect of the present invention, there is provided a method for providing useful information including character-based information for a fixed object, the method comprising the steps o
