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
