Patent ID: 7057627

Claim:
A video and graphics system comprising: a first input for receiving a graphics image comprising graphics pixels, each graphics pixels having square pixel aspect ratio; a second input for receiving a video image comprising video pixels, each video pixels having a non-square pixel aspect ratio, the video image having a larger number of pixels per scan line than the graphics image; a sample rate converter for converting sample rate of the graphics image to scale the graphics image horizontally, the sample rate converter including a multi-tap filter having at least three taps for converting the sample rate of the graphics image, thereby generating a scaled graphics image including scaled graphics pixels, each scaled graphics pixel having the square pixel aspect ratio, such that a number of the scaled graphics pixels per scan line of the scaled graphics image becomes greater than or equal to a number of the video pixels per scan line of the video image; and a video compositor for blending the scaled graphics image with the video image.
