7 Summary and Conclusions

The home entertainment ecosystem is transitioning from isolated analog devices
into a network of interconnected digital devices. Driven by new developments
in semiconductors, coding and digital communications, these devices can share
photos, music, and videos using a home network, enhance the user experience, and
continue to drive the development of new digital signal processing algorithms and
architectures.

8 To Probe Further

A good overview of the digital camera processing pipeline is given by [ 16 ] . An
overview of image and video compression standards, covering both theory and
architectures, including the JPEG [ 7 ] , MPEG-1 [ 8 ] , MPEG-2 [ 9 ] , AAC [ 10 ] , and
MPEG-4 [ 6 ] standards, can be found in [ 2 ] . The H.264 standard, also known as
