View source for CODEC Acceleration

'''[[Codec]] Acceleration''' describes [[Computer|computer]] [[Computer hardware|hardware]] that offloads the computationally intensive [[Data compression#Video|compression]] or decompression.  This allows, for instance, a mobile phone to decode what would generally be a very difficult, and expensive video to decode it with no stuttering, and using less battery life than un-accelerated decoding would have taken, and similar acceleration is used on a broad variety of other appliances and computers for similar reasons.  What could take a general purpose [[Central processing unit|processor]] 100 [[Watt]]s to decode on a general purpose processor, could take 10W on a general purpose GPU, and even less on a dedicated hardware CODEC.

==Video Codec Acceleration==
Video codec acceleration is where video (usually including audio as well) encoding and decoding is accelerated in hardware.

==Audio Codec Acceleration==
Audio codec acceleration is where audio encoding and decoding is accelerated in hardware.
