Simulated voice packet messaging
First Claim
1. A method for communicating in two-way interactive broadcast data service using an interactive data appliance (IDA) wherein said two-way interactive broadcast data service employs at least one central transmitting station (CTS) and at least one local remote receiver, said method of communicating comprising the steps of:
- selecting a data message for transmission from said IDA, said data message corresponding to at least one synthesized voice message, andtransmitting said data message from said IDA over said two-way interactive broadcast data service to a second IDA,converting said data message at said second IDA to said corresponding at least one synthesized voice message.

Abstract
An interactive data appliance (IDA) having a receiver and transmitter for sending data messages in a two-way interactive broadcast data service communication system. In one embodiment, a user of a transmitting IDA selects a message from a list of messages stored in the IDA memory. The selected message is transmitted as a data message to a receiving IDA. The receiving IDA converts the data message to a synthesized voice message. Hence, the receiving IDA speaks the message selected by the user of the transmitting IDA.

5. An interactive data appliance (IDA) adapted for two-way interactive broadcast data service communication in a system employing at least one central transmitting station (CTS) and at least one local remote receiver, said IDA comprising:
-
receiver means for receiving synchronized signals from a CTS, memory means for storing a plurality of synthesized voice messages, means for receiving first data messages from a user of a separate IDA, said first data messages corresponding to at least one of said synthesized voice messages, means for converting said first data messages to said corresponding at least one synthesized voice message, selector means for selecting at least one of said plurality of synthesized voice messages, a transmitter for transmitting a second data message from said IDA to a separate IDA, said second data message corresponding to said selected at least one of said plurality of synthesized voice messages, said transmitter having a maximum power output in the milliwatt range. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)

13. An interactive broadcast data system comprising:
-
at least one low power mobile interactive data appliance (IDA) located in at least one of a plurality of geographic zones of at least one geographic area, said at least one IDA further including; receiver means for receiving synchronized signals from a CTS, memory means for storing a plurality of synthesized voice messages, means for receiving first data messages from a user of a second at least one IDA, said first data messages corresponding to at least one of said synthesized voice messages, means for converting said first data messages to said corresponding at least one synthesized voice message, selector means for selecting at least one of said plurality of synthesized voice messages, and a transmitter for transmitting a second data message from said at least one IDA to a second at least one IDA, said second data message corresponding to said selected at least one of said plurality of synthesized voice messages, said transmitter having a maximum power output in the milliwatt range, a remote receive only station disposed within said at least one of said plurality of geographic zones for reception of transmissions including said voice messages from said at least one IDA located in said at least one of said plurality of geographic zones, a central transmitting station (CTS) disposed within said at least one geographic area, said CTS communicatively coupled to said receive only station disposed within said at least one of said plurality of geographic zones, said CTS having data processing and transmission facilities for transmitting to said at least one IDA and for receiving from said receive only station multiplexed synchronously related digital data messages of variable lengths, said data processing and transmission facilities including means for synchronizing said transmission facilities with a precision clock signal derived from an independent precision clock source, and facilities in said CTS and said at least one IDA for handing off communications between said plurality of geographic zones when communicated signals deteriorate below a given threshold.
