Project Concept  Build a system that is capable of streaming video wirelessly to a handheld device in real-time.  This system will serve as the basic framework upon which video sources can be added Live television Home surveillance Other personal media

Competitive Analysis  Basic Home Security Our project includes all functionality of traditional home security setups with added convenience of providing notifications and monitoring in a handheld device  Slingbox Our project will be able to relay stored data -- as Slingbox does -- as well as live data feeds (e.g. from television), which Slingbox does not.  Baby Monitors Traditional baby monitors provide only audio feeds. Those that also support video feeds do not provide the convenience of mobility when monitoring children.

Requirements  Functional Compress video as needed before transmitting it to the handheld device. Compression must be effective enough to allow uninterrupted viewing on the device. Provide a means by which the platform can be expanded. The software running on the desktop needs to be architected such that adding additional video sources is straightforward. Software must provide the ability for the user to select video inputs from the handheld device. The software must provide a user-configurable priority list. The video feed with the highest priority will be displayed if the feed becomes active. The handheld can connect to the video server from any wireless access point.  Timing Live feeds are delayed no more than 5 seconds by the conversion and transmission processes  Reliability The device attempts to reestablish connections following outages.
