Abstract

Abstract A video communication system includes a microprocessor for operating a tuner to select desired television channels in response to the input of corresponding channel numbers. A video data application program is Stored in a memory that is accessible to the microprocessor for providing an on-screen display generator with the video data program information for display. The microprocessor identifies the video data application program by a phantom channel number and when that channel number is input by the user, the microprocessor decodes it and accesses the memory location of the video data application program and activates the on-screen display generator.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 109 words
A method of operating a video communication system comprising: at a transmitter: assigning channel numbers to broadcast television channel signals; assigning a phantom channel number to a preselected video data program; at a receiver: using a microprocessor to select the broadcast television channel signals in:response to the input of the channel numbers corresponding to the broadcast television channel signals; using the microprocessor to access a memory containing the preselected video data program in response to the input of the phantom channel number identifying the video data program; and operating an on-screen display generator to generate a video display corresponding to the accessed preselected video data program in the memory.
Claim 2
Independent Claim 109 words
A method of operating a video communication system comprising: at a transmitter: assigning channel numbers to broadcast television channel signals; assigning a phantom channel number to a preselected video data program; at a receiver: using a microprocessor to select the broadcast television channel signals in:response to the input of the channel numbers corresponding to the broadcast television channel signals; using the microprocessor to access a memory containing the preselected video data program in response to the input of the phantom channel number identifying the video data program; and operating an on-screen display generator to generate a video display corresponding to the accessed preselected video data program in the memory.
Claim 3
Independent Claim 97 words
The method of operating a video communication system comprising: at a transmitter: assigning channel numbers to broadcast television channel signals; assigning a phantom channel number to a preselected video data program; at a receiver: tuning the broadcast television channel signals in response to the input of the channel numbers corresponding to the broadcast television channel signals; accessing a memory containing the preselected video data program in response to the input of the phantom channel number identifying the preselected video data program; and generating a video display corresponding to the accessed preselected video data program in the memory.
Claim 4
Independent Claim 97 words
The method of operating a video communication system comprising: at a transmitter: assigning channel numbers to broadcast television channel signals; assigning a phantom channel number to a preselected video data program; at a receiver: tuning the broadcast television channel signals in response to the input of the channel numbers corresponding to the broadcast television channel signals; accessing a memory containing the preselected video data program in response to the input of the phantom channel number identifying the preselected video data program; and generating a video display corresponding to the accessed preselected video data program in the memory.
Claim 5
Dependent Claim 34 words
The method of claim 2, further including a microprocessor means for controlling the tuning and the accessing; and using the microprocessor means to decode the phantom channel number identifying the preselected video data program.
Claim 6
Dependent Claim 21 words
The method of claim 3, further comprising downloading the video data program from the transmitter to the memory in the receiver.
Claim 7
Dependent Claim 111 words
In combination: a television tuner; a microprocessor for controlling tuning of said television tuner to broadcast television channel signals in response to inputs of channel numbers; a memory accessible to said microprocessor; a video data application program identified in said memory by a transmitter assigned phantom channel number different from said channel numbers; on-screen displays means for developing a video display from said video data application program; and decoding means in said microprocessor responsive to the input of said transmitter assigned phantom channel number for decoding said transmitter assigned phantom channel number and accessing said memory to cause said on-screen display to display the output of said video data application program.
Claim 8
Dependent Claim 111 words
In combination: a television tuner; a microprocessor for controlling tuning of said television tuner to broadcast television channel signals in response to inputs of channel numbers; a memory accessible to said microprocessor; a video data application program identified in said memory by a transmitter assigned phantom channel number different from said channel numbers; on-screen displays means for developing a video display from said video data application program; and decoding means in said microprocessor responsive to the input of said transmitter assigned phantom channel number for decoding said transmitter assigned phantom channel number and accessing said memory to cause said on-screen display to display the output of said video data application program.
Claim 9
Dependent Claim 21 words
The combination of claim 5 wherein said video data application program is downloaded to said microprocessor for storage in said memory.
Claim 10
Dependent Claim 22 words
The combination of claim 6, further including; a data receiver coupled to said microprocessor for receiving said downloaded video data application program.
