Abstract
Abstract A television broadcasting method and apparatus. The broadcasting method generally includes the steps of multiplexing signals from a plurality of channels over a single carrier frequency, and transmitting the multiplexed signals to a reception circuit. The multiplexed signals are then demultiplexed at the reception circuit. The demultiplexed signals are then separated into separate channels, and then stored for a predetermined period of time. The signals of the selected channel are then decompressed and reconstructed on a real-time basis and are then displayed or viewed also on a real-time basis.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
87 words
A television broadcasting method comprising the steps of: (a) compressing and multiplexing signals from a plurality of channels over a single carrier frequency; (b) transmitting the multiplexed signals; (c) receiving the multiplexed signals; (d) demultiplexing and separating the received signals into separate channels; (e) storing the separated signals for a predetermined period of time; (f) selecting a desired channel; (g) decompressing and reconstructing the signals of the selected channel on a real-time basis; and (h) displaying the reconstructed signals of the selected channel on a real-time basis.
Claim 2
Dependent Claim
87 words
A television broadcasting method comprising the steps of: (a) compressing and multiplexing signals from a plurality of channels over a single carrier frequency; (b) transmitting the multiplexed signals; (c) receiving the multiplexed signals; (d) demultiplexing and separating the received signals into separate channels; (e) storing the separated signals for a predetermined period of time; (f) selecting a desired channel; (g) decompressing and reconstructing the signals of the selected channel on a real-time basis; and (h) displaying the reconstructed signals of the selected channel on a real-time basis.
Claim 3
Dependent Claim
41 words
The method as defined in claim 1, further including the steps of: (a) determining whether a particular channel has been selected; and (b) if the particular channel has not been selected, then automatically erasing the stored signals for that particular channel.
Claim 4
Dependent Claim
23 words
The method as defined in claim 1, wherein said transmitting step includes transmitting the compressed signals from the channels in a packet form.
Claim 5
Dependent Claim
66 words
The method as defined in claim 2, further including the steps of: (a) if the particular channel has been selected, then decompressing the signals of that particular channel; (b) reconstructing the originally transmitted signals from the decompressed signals; (c) displaying the reconstructed signals on a real-time basis; and (d) automatically erasing the compressed signals of that channel in preparation for storage of the next demultiplexed signals.
Claim 6
Dependent Claim
100 words
A television broadcasting apparatus comprising: (a) means for compressing and multiplexing signals from a plurality of channels over a single carrier frequency; (b) means for transmitting the multiplexed signals; (c) means for receiving the multiplexed signals; (d) means for demultiplexing and separating the received signals into separate channels; (e) means for storing the separated signals for a predetermined period of time; (f) means for selecting a desired channel; (g) means for decompressing and reconstructing the signals of the selected channel on a real-time basis; and (h) means for displaying the reconstructed signals of the selected channel on a real-time basis.
