Interesting Apple patents
Apple was recently granted several interesting patents.
The first one
offers a method of analyzing video frames and working out their attributes such as if the footage is interlaced
, and if pulldown
has been applied or not. This would allow software such as Final Cut Pro to change project settings to match these attributes automatically without any user intervention. It would also allow software like Compressor to work out which fields
in interlaced footage are duplicates and only rendering them once, thereby speeding up rendering times and reducing file sizes. I would imagine this is geared at ProRes, Apple's professional codec.
The second patent
is for a DVD web system that provides a method of controlling - and being controlled by - internet content. Web content is currently available via next generation HD DVD and Blu-ray players but this patent specifically caters for two-way communication and control.
Their final patent
covers color correction
using an accelerated graphics card rather than the processor. My first thought was that it was a patent for the technology in Apple Color but further reading revealed that Apple proposes a playback system (such as QuickTime) where the original color space
of the video (such as NTSC
) could be converted to the current color space of the monitor to ensure accurate color reproduction.
It must be noted that Apple ultimately may not choose to implement these technologies into their products.
