Multistandard Picture-In-Picture (PIP)
controller
Preliminary specification
SAB9079HS
FEATURES
• Suitable for single PIP, double window and multi PIP
applications
• Data formats 4 : 1 : 1 (all modes) and 4 : 2 : 2 (most
modes)
• Sample rate of 14 MHz, 720 Y*-pixels/line
• Horizontal reduction factors 1⁄1 3⁄4, 2⁄3, 1⁄2, 1⁄3, 1⁄4 and 1⁄6
• Vertical reduction factors 1⁄1, 1⁄2, 1⁄3 and 1⁄4
• PIP OSD for the sub channels displayed
• Detection of PAL/NTSC with overrule bit
• CTE/LTE like circuits in display part
• Replay with definable auto increment, picture sample
rate and picture number auto wrap
• Programmable Y*UV to RGB conversion matrix with
independent coefficients for NTSC and PAL sources
• Display clock and synchronisation are derived from the
main PLL
• Three 8-bit Digital-to-Analog Converters (DACs)
• Three 8-bit Analog-to-Digital Converters (ADCs)
(7-bit performance) with clamp circuit for each
acquisition channel
• Main and sub can write to the same VDRAM address
spaces under certain conditions; the reduction factors
should be the same
• Y* and UV pedestals on the acquisition sides
• Independent vertical filtering with 1 : 1 for UV and Y* at
the display part.
GENERAL DESCRIPTION
The SAB9079HS is a PIP controller for a multistandard
application environment in combination with a
multistandard decoder such as for example TDA8310,
TDA9143 or TDA9321H.
The SAB9079HS inserts one or two live video signals with
reduced sizes into the main/display video signal. All video
signals are expected to be analog baseband signals. The
analog signals are stripped signals without sync.
Therefore the luminance signal is referred to as Y*. The
conversion into the digital environment and back is done
on-chip as well as the internal clock generation.
The SAB9079HS is suitable for single PIP, double window
and multi PIP applications.
