To form a complete TV set, the video backend must be complemented with additional components. Due to the flexible architecture of the DDP 3315C, it can be placed in various environments. Applications to display digital MPEG or PC graphics on large screens, inserting analog VGA sources in a TV as well as memory-based image processing for 100/120 Hz or progressive scan rate conversion of TV sources, are intended with the DDP 3315C.

The block diagram depicts several VPC applications. Since the VPC functions as a video front-end, it must be complemented with additional functionality to form a complete TV set. The DDP 331x contains the video back-end with video postprocessing (contrast, peaking, CTI,...), H/V-deflection, 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 323xD provides a high-quality analog RGB interface with character insertion capability. It also allows appropriate processing of external sources, such as MPEG 2 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 European countries (Italy), this feature is mandatory. SRC (e. g. SDA 94xx from Micronas) 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 VPC 323xD provides a 656 output interface and FIFO control signals. Examples:Europe: 15 kHz/50 Hz - 32 kHz/100 Hz interlacedUS: 15 kHz/60 Hz - 32 kHz/60 Hz non interlaced
