VdP

VDP is an acronym that can refer to several concepts depending on the context. Among common uses are Video Display Processor, Voluntary Disclosure Program, and Vin de Pays. The meaning is usually clarified by the field of discussion, since VDP has specialized significance in computing, taxation, and wine labeling.

Video Display Processor refers to a dedicated graphics processor that generates video output, typically handling tile-based backgrounds, sprites, color palettes, and raster timing. VDPs are usually connected to video RAM and controlled by the central processor to set display modes and fetch graphics data. They were common in 8- and 16-bit consoles and arcade boards; examples include Sega Master System family VDPs (TMS9918A-compatible) and Yamaha V9938/V9958 used in MSX machines.

In taxation and regulation, a Voluntary Disclosure Program allows individuals or entities to reveal previously unreported information in exchange for relief from penalties or enforcement actions. Programs vary by jurisdiction and may require full disclosure, cooperation with audits, and payment of owed taxes with interest. Relief is not guaranteed and disclosures may still face review.

Vin de Pays, often abbreviated VdP, was a French wine classification indicating geographic origin and certain production rules, used before the adoption of the IGP system. The designation appears on some labels and catalogs, particularly for older bottles, and is largely superseded in modern labeling but remains recognized in historical contexts.
