1.2. DDP Applications
Fig. 1–2 depicts several DDP applications. Since the
DDP functions as a video back-end, it must be
complemented with additional functionality to form a
complete TV set.
The DDP 3310 B will be a further development of the
DDP 3300 A. It is targeted for a system with a horizontal
frequency of 32 kHz and a vertical frequency of 100 or
120 Hz.
The VPC3210A/3211B processes all worldwide analog
video signals (including the European PALplus) and al-
lows nonlinear Panorama aspect ratio conversion. Thus
4:3 and 16:9 systems can easily be configured by soft-
ware. The aspect ratio scaling is also used as a sample
rate converter to provide a line-locked digital component
output bus (YCrCb) compliant to ITUR–601. All video
processing and line-locked clock/data generation is
derived from a single 20.25 MHz crystal. An optional
adaptive 2-line combfilter (VPC3211B) performs Y/C
separation for PAL and NTSC and all of their substan-
dards. Both versions of the VPC are plug-in compatible.
The CIP 3250 A provides a high-quality analog RGB in-
terface with character insertion capability. This allows
appropriate processing of external sources such as
MPEG2 set-top boxes in transparent (4:2:2) quality. Fur-
thermore, it translates RGB/Fastblank signals to the
common digital video bus and makes those signals
available for 100 Hz processing. In some European
countries (Italy), this feature is mandatory.
The IP indicates memory based image processing, such
as scan rate conversion, vertical processing (Zoom), or
PAL+ reconstruction.
Examples:
– Europe: 15 kHz/50 Hz
→
32 kHz/100 Hz interlaced
– US: 15 kHz/60 Hz
→
31 kHz/60 Hz non-interlaced
Note that the VPC supports memory based applications
through line-locked clocks, syncs, and data. CIP may
run either with the native DIGIT3000 clock but also with
a line-locked clock system.
