When 60 de-interlaced fields per second digital uncompressed video is streamed to a computer, some video fields are lost and not able to be stored on a computer’s hard drive successfully. Additionally, this problem amplifies once multiple video sources are deployed. If it is possible to stream digital uncompressed video without dropped video fields, then a sophisticated computer analysis of the...

Recent advances in wireless technology and decreasing costs of portable devices strongly contributed to increase the popularity of mobile communications. Wireless communication and device integration have lead to the so-called nomadic computing (or mobile computing) where portable devices (such as laptop and handheld computers) allow users to access Internet and data on their home or work compu...
