Broadband A/V Home Networking
With the advance of communications and networking technologies, the networked home market has taken off for years. A networked home allows the people to have the simultaneous Internet access from different parts of the home, and to share the devices and contents within the home. This project focuses on audio/video home networking technologies that will allow the redistribution and sharing of A/V contents through a unified wired/wireless home network. The solution will lead to a new networked A/V consumer electronics business.
Background & Objective: The new upcoming IEEE802.11e standard that will support the applications with QoS requirements is paving a way for customers to have a multimedia wireless home network. With the existing wired infrastructure, the future home network will be a mixed wired/wireless network. The main objective of the project is to develop an interworking protocol that allows the smooth and reliable connections between wired (i.e. 1394, Ethernet, and digital cable) clusters and wireless (i.e. 802.11) clusters.
Technical Discussion: Unlike the original 802.11 standard, 802.11e supports the real-time applications such as voice, video with guaranteed QoS, i.e. guaranteed bandwidth, bounded delay and so on. This makes wireless multimedia home networking a reality. The major technical hurdle here is to develop an interworking protocol between 802.11e and other existing wired standards such as 1394, Ethernet. In the project, we design the PAL (protocol adaptation layer) between 802.11e and 1394, such that 1394 data can be smoothly transmitted over 802.11e without loss of quality and vice versa. We also research and implement the mapping algorithms between IP DiffServ and 802.11e to optimize the network's performance.
