Abstract
In a closed circuit television system having a central facility connected to a plurality of terminals, it is possible to display billing data showing charges for hotel accommodations, pay television reception, equipment use, etc., at the terminals. The computer in the central facility stores data corresponding to the charges owed by a customer at one of the terminals. When a customer wishes to see his bill, he depresses a button at his terminal. The appropriate charges are retrieved from the computer and displayed at the terminal.
Claims10
A billing data display system for a closed circuit TV system in which a central facility transmits video signals to a plurality of connected terminals, each of which is operated by a respective customer, said system comprising:
- a computer at said central facility for storing data corresponding to charges owed by said customers;
- means for requesting billing data from said central facility;
- a plurality of first character generators at said central facility which are responsive to a billing data request from said terminals for converting charge data provided by said computer into video data which is transmitted to said terminals;
- and
- means at each terminal for displaying said billing data,
- wherein said central facility further comprises means for transmitting predetermined messages to said terminals when the number of billing data requests is larger than the number of said first character generators.
A billing data display system for a closed circuit TV system in which a central facility transmits video signals to a plurality of connected terminals, each of which is operated by a respective customer, said system comprising:
- a computer at said central facility for storing data corresponding to charges owed by said customers;
- means for requesting billing data from said central facility;
- a plurality of first character generators at said central facility which are responsive to a billing data request from said terminals for converting charge data provided by said computer into video data which is transmitted to said terminals;
- and
- means at each terminal for displaying said billing data,
- wherein said data stored in said computer includes data corresponding to charges for equipment other than for viewing pay television programs used by said customers.
A terminal used in a billing data display system for a closed circuit TV system, said billing data display system using a central facility to transmit video signals to a plurality of connected terminals, said terminal comprising:
- bill requesting means operated by a customer;
- means for sending, in response to manipulation of said bill requesting means by said customer, address information of said terminal and a billing data request signal to said central facility;
- means, responsive to predetermined message tuning data transmitted to said terminal from said central facility after a billing data request is initiated and prior to the transmission of billing data, for forceably timing said terminal to a first predetermined channel on which said central facility transmits a predetermined message, all said terminals in said system having the same first predetermined channel;
- means responsive to a billing signal tuning signal, for forceably tuning said terminal to a selected channel in which said central facility transmits billing data for the specific terminal;
- and
- means for displaying said billing data and said predetermined messages.
