System and method for video downscaling

A system for downscaling video signal data to an arbitrary size, said system comprising:

• an antenna receiving video signal data;
• an analog-to-digital converter coupled to said antenna and converting said received analog signal data to digital signal data;
• a memory component storing video downscaling instructions;
• and
• a video downscaling processor, coupled to said memory component and said analog-to-digital converter, wherein said video downscaling processor, upon reading said video downscaling instructions from said memory and executing said downscaling instructions:
• divides said digital video signal data into a plurality of blocks, wherein each block comprises a plurality of pixel elements;
• and
• cycles through said plurality of blocks, and for every block in said plurality of blocks, generates a new block, wherein said new block comprises a plurality of new pixels evenly spaced within said new block,
• wherein said plurality of blocks comprises a vertical block of horizontal lines as transmitted according to at least one of National Television System Committee (NTSC) standard of analog video signal data transmission, Phase Alternate Line (PAL) standard of analog video signal data transmission, and Sequential Color with Memory (SECAM) standard of video signal data transmission, and
• wherein each said pixel element from said plurality of pixel elements comprises a horizontal line pair and each new pixel in said plurality of new pixels is generated from said horizontal line pair.

A method of downscaling video signal data to produce evenly spaced downscaled video signal data, said method comprising:

• providing video signal data;
• dividing said video signal data into a plurality of blocks, where each block comprises a plurality of pixel-block pairs;
• cycling through said plurality of blocks, and for every block in said plurality of blocks, generates a new block, wherein said new block comprises a plurality of new pixel-block pairs spaced within said new block;
• and
• calculating, for each pixel-block pair in said plurality of pixel-block pairs, a new pixel-block from said pixel-block pair,
• wherein said new pixel-block is calculated as (1−d)*M1+d*M2, where M1 is a first pixel-block of said pixel-block pair, M2 is a second pixel-block of said pixel-block pair and d is a calculated distance from a start point of said pixel-block pair.
