The Performance of a DTV Receiver

Performance of a DTV receiver relies on the connections and the AV wiring.

The reliability of a Digital TV (DTV) receiver is based on complex equipment and signal distribution of the digital television system. However, the receiver's performance in a customer's home is dependent on a few factors, each under the customer's control.

Misconceptions About Satellite-based DTV Service

The reliability of digital TV's service has been greatly misconstrued. When using satellite-based TV service, as long as the dish is securely mounted, aligned and located in an area that provides an unobstructed view of the proper region of the sky, a satellite-based DTV receiver will operate flawlessly.

Coaxial Cable Quality and Connectors

Compression fittings do not disrupt digital TV signals.

When cable TV first appeared on the market, inexpensive connectors were crimped onto cable ends, and various grade cables were used. In order to have reliable satellite or cable DTV service, the cabling in the home must be rated "RG6" and the connectors should be compression fittings. Twist-on and crimp-on connectors should not be used in a DTV system.

Connections Between the Receiver and the Television

By using high quality cabling between the receiver and a television, the DTV receiver will provide a quality viewing experience. The following are listed in decreasing level of picture and sound quality.

1. If using HD equipment, an HDMI cable and optical audio will provide the highest quality digital viewing and 5.1 Dolby audio experience.

2. Component video and RCA audio will provide HD video and stereo sound.

3. "S" video and RCA audio will offer the next best quality.

4. Three-color RCA audio and video will offer clear standard definition video and stereo audio.

5. If no other options are available, a coaxial cable connecting the receiver and the television will offer basic quality picture and sound.

Heat Distribution

Any AV equipment will fail prematurely or provide unreliable service if located in a cabinet that collects heat. If installed in furniture or built in to a cabinet, the enclosure must be vented to dissipate heat. The DTV receiver and related AV equipment should never feel warm to the casual touch. If heat collects in the cabinet, consider cutting ventilation holes in the rear or adding a small ventilation fan.
