Video

Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media.

Video systems vary greatly in the resolution of the display, how they are refreshed, and the rate of refreshed, and 3D video systems exist. They can also be carried on a variety of media, including radio broadcast, tapes, DVDs, computer files etc.

History

Video technology was first developed for Mechanical television systems, which were quickly replaced by cathode ray tube (CRT) television systems, but several new technologies for video display devices have since been invented. Charles Ginsburg led an Ampex research team developing one of the first practical video tape recorder (VTR). In 1951 the first video tape recorder captured live images from television cameras by converting the camera's electrical impulses and saving the information onto magnetic video tape.

Video recorders were sold for $50,000 in 1956, and videotapes cost $300 per one-hour reel. However, prices gradually dropped over the years; in 1971, Sony began selling videocassette recorder (VCR) decks and tapes to the public.

Brandy

Brandy (from brandywine, derived from Dutch brandewijn, "gebrande wijn" "burned wine") is a spirit produced by distilling wine. Brandy generally contains 35–60% alcohol by volume (70–120 US proof) and is typically taken as an after-dinner drink. Some brandies are aged in wooden casks, some are coloured with caramel colouring to imitate the effect of aging, and some brandies are produced using a combination of both aging and colouring.

In broader sense, the term "brandy" also denotes liquors obtained from distillation of pomace (pomace brandy) or mash or wine of any other fruit (fruit brandy). These products are also named eaux-de-vie.

Varieties of wine brandy can be found across the winemaking world. Among the most renowned are Cognac and Armagnac from Southwestern France.

History

The origins of brandy were clearly tied to the development of distillation. While the process was known in classical times, it wasn't used for significant beverage production up until the 15th century.

Initially wine was distilled as a preservation method and as a way to make it easier for merchants to transport. It is also thought that wine was originally distilled to lessen the tax which was assessed by volume. The intent was to add the water removed by distillation back to the brandy shortly before consumption. It was discovered that after having been stored in wooden casks, the resulting product had improved over the original distilled spirit. In addition to removing water, the distillation process led to the formation and decomposition of numerous aromatic compounds, fundamentally altering the composition of the distillate from its source. Non-volatile substances such as pigments, sugars, and salts remained behind in the still. As a result, the taste of the distillate was often quite unlike that of the original source.

Microsoft Video 1

Microsoft Video 1 or MS-CRAM is an early lossy video compression and decompression algorithm (codec) that was released with version 1.0 of Microsoft's Video for Windows in November 1992. It is based on MotiVE, a vector quantization codec which Microsoft licensed from Media Vision. In 1993, Media Vision marketed the Pro Movie Spectrum, an ISA board that captured video in both raw and MSV1 formats (the MSV1 processing was done in hardware on the board).

Compression algorithm

Microsoft Video 1 operates either in a 8-bit palettized color space or in a 15-bit RGB color space. Each frame is split into 4×4 pixel blocks. Each 4×4 pixel block can be coded in one of three modes: skip, 2-color or 8-color. In skip mode, the content from the previous frame is copied to the current frame in a conditional replenishment fashion. In 2-color mode, two colors per 4×4 block are transmitted, and 1 bit per pixel is used to select between the two colors. In 8-color mode, the same scheme applies with 2 colors per 2×2 block. This can be interpreted as a 2-color palette which is locally adapted on either a 4×4 block basis or a 2×2 block basis. Interpreted as vector quantization, vectors with components red, green, and blue are quantized using a forward adaptive codebook with two entries.
