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

1. 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.

2. 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.

3. The method as defined in claim 1, wherein said transmitting step includes transmitting the compressed signals from the channels in a packet form.

4. 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.

5. 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.
