PIP Horizontal
Size The Picture-In-Picture horizontal size can be changed to any of the
following 4 sizes – full, half, quarter, thumbnail.
PIP Vertical Size The Picture-In-Picture vertical size can be changed to any of the
following 4 sizes: full, half, quarter, thumbnail.
Brightness (0 – 15) The luminance is the information about the varying light
intensity of an image, is best described as brightness. Default = 0.
Saturation (0 – 15) The saturation is the spectral purity or intensity of a color.
Default = 8.
Hue (-16 to +15) 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. Default is 0.
Adding hue reduces the saturation. Note that the Picture in Picture
display will override the display of Closed Caption text.
Transport Rate This option allows selection of the actual transport rate for the
MPEG-2 transport stream transmitted from this encoder. If Auto is
selected, the VBrick will choose an appropriate conservative transport
rate, which will allow any video interval to be clearly transmitted. If
you enter a rate that is less than the combined video, audio and over-head an
error message will be displayed indicating that the rate selected is too low.
Actual Transport R
ate This read-only parameter provides the actual transport stream rate. It
is of particular interest when the automatic option is selected above.
Even if a transport rate is explicitly selected, the actual transport rate
will differ from the selected rate since only certain rates are supported.
