CABLE TELEVISION ENTRY ADAPTER
First Claim
1. A cable television (CATV) entry adapter comprising:
- a local-area-network (LAN) signal transmission path;
an in-home entertainment (IHE) signal transmission path; and
a LAN-to-radio-frequency (RF) transceiver, wherein the LAN-to-RF transceiver electrically couples the LAN signal transmission path to the IHE signal transmission path.

Abstract
A cable television (CATV) entry adapter is disclosed which provides a means and method for transmitting upstream CATV requests to a CATV network without using an active upstream CATV signal path. The disclosed CATV entry adapter includes a transceiver that converts local-area network (LAN) signals to radio-frequency (RF) signals of an in-home entertainment (IHE) signal bandwidth, and vice versa. The LAN-to RF transceiver couples a LAN signal transmission path and an IHE signal transmission path within the entry adapter. The LAN-to RF transceiver converts IHE signals with encoded upstream CATV requests to LAN signals that include the upstream CATV requests. The LAN signals with upstream CATV requests can then be delivered to a cable modem for conversion into passive upstream CATV signals that include the encoded upstream CATV requests. The entry adapter can then deliver the passive upstream CATV signals with encoded upstream CATV requests to the CATV network.
