VIDEO

These inputs should be connected to a Composite Video signal

(CVBS) by means of a cable with an RCA connector.

The connector on the source is usually yellow and is frequently

labelled VIDEO.

Although other types of signals are preferable (since they

allow better picture quality), this is still the most common type

of output, and nearly all television receivers, video-recorders,

DVD players, video cameras, etc., are equipped with CVBS

outputs.

S-VIDEO

These inputs should be connected to an S-Video signal by

means of a cable with a 4-pin mini-DIN type connector.

The corresponding output on the source can be identiﬁed by

the wording S-VIDEO or Y/C.

Almost as widespread as Composite Video, S-VIDEO is prefe-

rable because it offers a clearer and sharper picture.

COMPONENT / RGBS

These inputs are composed of three sets of 5 RCA connectors

(5,6,7) and a set of 5 BNC connectors (8).

Each set of connectors is suitable for RGB and Component

signals.

RGB signals can have the following synchronisations: compo-

site sync on the green signal (RGsB), H+V Composite Sync,

or separate H/V Sync.

Connect the R, G, B outputs of the source to the respective R,

G, B inputs of the DigiOptic™ Image Processor (paying attention

not to invert the positions) and any synchronisation signals to

the HV input or the H and V inputs. When connecting the three

sets of RCA connectors use the colours as a guide: connector

R is red, G is green, B is blue, H/HV is white and V is black.

By using a suitable SCART to RCA (or BNC) connector adapter

cable, an RGB video signal from a source equipped with an

SCART connector can be connected to this input.

Component signals are connected to inputs Y, Cr and Cb,

taking care to observe the correspondence with the outputs

on the source.

Since the latter can be labelled in various ways, refer to Table 1

to establish the correspondence between the various signals.

The connector colours can also be of help, as shown in the

table.

Input 5 is dedicated for RGB and YCrCb signals up to 32 KHz

only. In fact, in order to guarantee a high image quality, even

with not so accurate sources, the input signal is elaborated by

speciﬁc circuit boards in the DigiOptic™ Image Processor.

The video signal suitable for inputs 6-7-8 can have a scan

frequency of 15KHz (standard video resolution) or 32KHz or

more (progressive scan video, high deﬁnition video).

Some sources provide the facility to choose between a pro-

gressive signal or an interlaced signal. Although in general a

progressive signal is higher quality than an interlaced signal, it

is often preferable to perform the deinterlacing operation on the

HT300 E-LINK system rather than on the source because the

HT300 E-LINK system is equipped with Faroudja’s sophisticated

directional correlation deinterlacing technology (DCDi™).

Progressive signals usually provide better quality than interla-

ced signals, but if the source features both progressive and

deinterlaced signal outputs it is good practice to compare the

quality of the pictures reproduced by the HT300 E-LINK system

in the two cases: deinterlacing performed by the HT300 E-LINK

system (thanks to Faroudja DCDi™ technology) is often more

effective than that performed at the source (typically a DVD
player).

RGB GRAPHICS

This input should be connected to an RGB-type video or graphic

signal using a cable with a DB15HD type connector.

The signal source device (typically a personal computer or

game console) must be able to provide separate H/V synchro-

nisation or composite H+V.

The video or graphic signals that can be connected to this input

can have horizontal scan frequencies (H-sync) of between 32

and 80 kHz and a vertical frequency (V-sync) of between 48

and 100 Hz. Image resolution can vary between 640x480 and

1600x1200 pixels (VGA, SVGA, XGA, SXGA, UXGA).
