GigaDVP

Note: this is advance information, the GigaDVP is scheduled for delivery in second quarter of 2003. For immediate requirements, look at the μGVP

The GigaDVP Digital Video Processor

Summary of capabilities:

Reads timecode in various formats: LTC, DVITC, ANC
Generates timecode in various formats: LTC, DVITC, ANC
Converts timecode from format to other
Decode/encode Close Caption (including Text, XDS (including v-chip)
Encode the STM or similar data carrying signal
Display text (character generator) and subtitles

Insert/extract/process ancillary data
Monitor presence/integrity of signals

The GigaDVP, due to its largely programmable architecture can be adapted to a wide range of applications that require any of the above capabilities or a combination of these.

GigaDVP architecture

The GigaDVP video processor comprises a serialiser and de-serialiser circuit. These circuits provide input an output to a proprietary video processing unit implemented in programmable logic. Two memory blocks supply data and instructions to the video processing unit. These two memory blocks are completely independant so that one can be prepared while the other is being displayed. A fast RISC microcontroller is used to manage the unit and prepare the video signal data stream.
