Video Features

Your AVR is the heart of your home theater system. All of your audio and video

components connect to it. Modern video components will connect through the HDMI

inputs. HD video must either connect through HDMI or component inputs. If given the

choice, always use HDMI. In addition, the AVR may offer a composite input for con-

necting an older VCR or camcorder.

The HDMI connection will carry both the video and the audio, making separate

cables for each unnecessary. Since HDMI was introduced, it has been upgraded sev-

eral times. HDMI 1.4 or later is necessary for 3D TVs. You can still use an older AVR

with a 3D TV if you have a Blu-ray player with two HDMI outputs. One output con-

nects to the AVR for audio and the other goes directly to the TV for video. In that

case, the AVR would not be handling the video. If you don’t intend to have a 3D TV,

you do not need an AVR with HDMI 1.4.

For switching to your different sources, make sure the AVR has at least 4

HDMI inputs (for switching your Blu-Ray player, cable box, video game, etc). It is also

advisable to look for an AVR with 2 HDMI outputs. This will allow you to feed both a

TV and a projector in case you have both of these.

In addition to switching A/V sources, AVRs offer a lot of video processing op-

tions, among them upscaling circuitry that adds lines of resolution to standard defini-

tion video. Many AVRs also offer controls that let you adjust the video picture. It is

our opinion that the upscaling circuitry and the video controls should be a function of

your TV or projector and that those in the AVR usually are unnecessary and should

be bypassed in order to avoid conflicts. Make sure that any AVR you are considering

offers the ability to completely pass the video through it unprocessed in any way.

Surround Modes

A major function of an AVR is to provide surround sound. Over the years sur-

round sound formats have truly evolved. First, there was Dolby

Pro Logic. This cir-

cuitry would take the 2 channels of audio from the VCR and synthesize additional

surround sound channels. Although this wasn’t the same as five separate channels,

its surround effect can be pretty convincing at times.
