Digital enhancement of streaming video and multimedia system

A method for enhancing digital video such that an original small-frame digital video can be enlarged and displayed as a large-frame video with high resolution and quality, said original digital video including a sequence of image frames, each said image frame comprising limited number of columns and rows of pixels, said method comprising the steps of:

• increasing number of rows and columns of pixels of each said image frame;
• and
• adjusting color characters of each new pixel created by said step of increasing;
• said step of increasing including dividing each pixel of the image frame of said original video into a plurality of child pixels, said new pixels comprising said child pixels;
• said step of adjusting including determining whether a pixel is an element-boundary pixel that contributes to the visual effect of a boundary of an image element within said image frame by evaluating amount of changes of color character differences between said pixel and its neighboring pixels.
