Current connectivity trendWireless connectivity

wired->wireless Home Network

• A/V system cable (connection between CEs)

• Contents share (control, low data rate -> ?)

Not just wireless –> Good quality

• Ex) Earphone, keyboard, mouse, etc

• Low Quality, lost, power, cost, design, durability

Possibly complicated connectivity technology
