Reference Distance

Reference Distance

For models ending in -xxx1/-xxx2, enables a user to set the

 

difference between consecutive reference frames within a group of

 

pictures (GOP). The values available are 1–3 (default = 2). If the

 

Encoder Transport Delay setting is low or medium, the value must be

 

1. Does not apply to models ending in -xxx0. If Reference Distance

 

and Intrapicture Distance are both 1, the encoder will produce all I

 

frames.

 

 

Intrapicture

Enables the user to set the distance between consecutive I frames

Distance

within a Group Of Pictures (GOP). The values available are 1–19

 

(default = 16). Does not apply to models ending in -xxx0. If

 

Reference Distance and Intrapicture Distance are both 1, the encoder

 

will produce all I frames.

 

 

Luminance

0 to 255. Default = 128. The luminance is the information about the

 

varying light intensity of an image, which is best described as

 

brightness.

 

 

Contrast

0 to 127. Default = 62. The contrast is the range of light-to-dark

 

values of an image that are proportional to the voltage differences

 

between the black and white levels of the signal.

 

 

Saturation

0 to 127. Default = 66. The saturation is the spectral purity or

 

intensity of a color.

 

 

Hue

Range is -128 to 127. Default = 0. The hue is the attribute by which a

 

color may be identified within the visible spectrum. Hue refers to the

 

spectral colors of red, orange, yellow, green blue and violet. Adding

 

hue reduces the saturation.

 

 

Resolution

For models ending in -xxx0, the video resolution can be adjusted to

 

be Full D1, 2/3 D1, ½ D1. For models ending in other than -xxx0,

 

the video resolution can be Full D1, 2/3 D1, ½ D1 or 352x240 (SIF).

 

Note that D1 resolution is not recommended at video encode rates

 

below 5 Mbps. In SIF mode only closed captioning CC1 and CC2 in

 

the menu settings of the video display are valid (TV menu monitor

 

settings) CC3 and CC4 fields are not supported. The actual

 

resolutions for NTSC and PAL are listed below:

 

NTSC D1 720x480

 

NTSC 1/2 D1 352x480

 

NTSC 2/3 D1 480x480

 

NTSC SIF 352x240

 

PAL D1 720x576

 

PAL 1/2 D1 352x576

 

PAL 2/3 D1 480x576

 

PAL CIF 352x288

 

 

Bit Rate

The encoder's bit rate can be adjusted from 1 Mbps to 10 Mbps for

 

models ending in –xxx0. For models ending in other than -xxx0, the

 

bit rate can be adjusted from 1–15 Mbps.
