When you asked about an alternative to an HD receiver, the rep recommended an alternative to the traditional, coaxial-cable, HD receiver: the wireless client. However, coaxial or wireless, it'd till be another box rental.
Is there a coaxial outlet in the Computer Room? Due to copy-right protection and encryption nowadays, providers have locked down TV service so it'd be difficult...if not impossible...to get Cox TV without a rental box.
If the Sony is to be just sports, you could subscribe to a streaming service to watch these games, especially in a room with the router/modem. If you want just general TV, there are also TV streaming services.
The wireless box would set between the Sony and Panoramic router. The Sony communicates with the Wireless box > Wireless box communicates with the Panoramic...and vice versa.
