1.3. VPC Applications
Fig. 1–2 depicts several VPC applications. Since the
VPC functions as a video front-end, it must be comple-
mented with additional functionality to form a complete
TV set.
The DDP 33x0 contains the video back-end with video
postprocessing (contrast, peaking, DTI,...), H/V-deflec-
tion, RGB insertion (SCART, Text, PIP,...) and tube
control (cutoff, white drive, beam current limiter). It
generates a beam scan velocity modulation output
from the digital YCrCb and RGB signals. Note that this
signal is not generated from the external analog RGB
inputs.
The component interface of the VPC 32xxD provides a
high-quality analog RGB interface with character inser-
tion capability. It also allows appropriate processing of
external sources, such as MPEG2 set-top boxes in
transparent (4:2:2) quality. Furthermore, it transforms
RGB/Fast Blank signals to the common digital video
bus and makes those signals available for 100-Hz up-
conversion or double-scan processing. In some Euro-
pean countries (Italy), this feature is mandatory.
The IP indicates memory based image processing,
such as scan rate conversion, vertical processing
(Zoom), or PAL+ reconstruction. The VPC supports
memory based applications through line-locked clocks,
syncs and data. Additionally, the VPC323xD provides
a 656-output interface and FIFO control signals.
Examples:
– Europe: 15 kHz/50 Hz → 32 kHz/100 Hz interlaced
– US: 15 kHz/60 Hz → 32 kHz/60 Hz non-interlaced
