52 RSX-1550 Surround Sound Receiver

Also with Blu-ray, but depending on the monitor being used to view the picture, you may also be able to enjoy new video enhancements such as Deep Color or XY video (also called Broad Color Space). Using the HDMI 1.3 connection, this receiver can pass these signals through from the Blu-ray player to a compatible monitor.

These new audio formats and video features are not available from standard DVD discs or players, even when an HDMI connection is used.

Can I connect components which have earlier versions of

HDMI?

Yes, because HDMI is backwards-compatible. This means that components which have earlier versions of HDMI (such as HDMI 1.1 or HDMI 1.2) will perform correctly when connected to the HDMI 1.3 inputs or outputs of the receiver.

If your DVD player is equipped with HDMI 1.2a, the HDMI connection will permit the transmission of 1080p (high definition) video signals.

Which is the best way to rescale the picture?

When using legacy components that require picture rescaling, it is better to use the monitor scaler to handle any picture resizing. You should try to use only one scaler in the system, so keep your DVD player set to 480p or 1080p. A 480p signal will be rescaled by the monitor and a 1080p signal will be seen by a monitor with 1080p resolution as a native signal.

Some Blu-ray and HD-DVD discs have been recorded in 1080i. These should not be scaled, but are best left to the monitor to interpret into an appropriate format for the screen.

Will the HDMI digital output improve the picture quality from old analog sources?

Analog picture sources from legacy units begin by being less good than digital signals, and while the receiver will translate them into a digital format, the final quality will be constrained by the original source, and the choice of connection (Composite, S-Video or Component). The scaler cannot correct for low resolution signals and will not improve inherently poor picture quality.

Why does the HDMI connection sometimes not give a picture?

Although it is simple to use, the HDMI connection is actually a highly complex electrical circuit, and within it is a security system called HDCP (High Definition Content Protection). In some circumstances pictures may not reproduce, or may not reproduce properly, due to the action of DRM (Digital Rights Management) or the ‘handshake’ between

the two connected units. HDMI cables contain circuits that exchange a ‘handshake’ signal several times a second, designed to maintain the integrity of the transmission signal and to prevent attempted unauthorized copying of copyright material. However, these ‘handshake’ signals can be disrupted for several reasons. If problems persist, consult your Rotel dealer.
