Abstract

A receive device includes a plurality of demodulators and a tunnel destination. The demodulators are configured to receive multiple data streams, each of the multiple data streams having a bit rate that is lower than a bit rate of a transmit data stream. The tunnel destination is configured to recombine the multiple data streams to provide a receive data stream having a bit rate equal to the bit rate of the transmit data stream. At least one of multiple radio frequency channels is connected to a legacy user between a transmit site and the receive device.

Claims

1. A receive device for receiving a transmit data stream from a transmit site over a cable network having multiple radio frequency channels, the transmit data stream divided into multiple data streams, the receive device comprising:

a plurality of demodulators configured to receive the multiple data streams, each of the multiple data streams having a bit rate that is lower than a bit rate of the transmit data stream; and

a tunnel destination configured to recombine the multiple data streams to provide a receive data stream having a bit rate equal to the bit rate of the transmit data stream,

wherein at least one of the radio frequency channels is connected to a legacy user between the transmit site and the receive device.

2. A receive device for receiving a transmit data stream from a transmit device over a cable network having multiple radio frequency channels, the transmit data stream divided into multiple data streams, the receive device comprising:

a plurality of demodulators configured to receive the multiple data streams, each of the multiple data streams having a bit rate that is lower than a bit rate of the transmit data stream; and

a tunnel destination configured to recombine the multiple data streams to provide a receive data stream having a bit rate equal to the bit rate of the transmit data stream,

wherein at least one of the radio frequency channels is connected to a legacy user between the transmit device and the receive device.

3. A receive device for receiving a transmit data stream from a transmit site over a cable network having multiple radio frequency channels, the transmit data stream divided into multiple data streams, the receive device comprising:

a plurality of demodulators configured to receive the multiple data streams, each of the multiple data streams having a bit rate that is lower than a bit rate of the transmit data stream; and

a tunnel destination configured to recombine the multiple data streams to provide a receive data stream having a bit rate equal to the bit rate of the transmit data stream,

wherein at least one of the radio frequency channels has connections to a plurality of legacy users and the connections are between the transmit site and the receive device.
