HDMI's Lip Sync and audio-video synchronization for broadcast and home video
HDMI 1.3 includes a Lip Sync feature to address the rampantly rising problem of poor audio-video synchronization resulting from numerous digital video processing steps in the television signal chain. But compliance is voluntary, and for a variety of reasons, CE devices and HDTVs may vary significantly in their synchronization performance.

Smart camera basics: Matching image sensor, analytics and processor performance
Start designing intelligent network cameras -- "smart cameras" with built-in analytics -- by defining the optimal image sensor, codec(s), camera sensor interface, multistreaming abilities, image pipe, and other key parameters.
What you need to know about imaging solutions for camera phones
Today's camera phones will give way to 'intelligent' phones that use their image camera subsystems in ways beyond simple still image or video capture. Here is a look at how to select the right image sensor and other components in the camera systems--things you 'must know' for your designs--in order to stay ahead of the pack.
How to give crime-fighters a flexible, high-performance edge with programmable logic
This article examines the use of FPGAs and soft-core embedded processors in two crime-fighting applications: a fingerprint identification system and a wireless auto-tracking camera.
