ARCHITECTURE
MOTIVATION
People are busy and need to
watch many things at once.
Ultimately, things must be
prioritized, but why not view
them on one device?
Receive, Process, Redirect Data
User
Human
Interaction

We can use a device to view:
television, home surveillance,
baby monitor, movies, ……..
Display Data
Objective:
Send Raw Data
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.
