This document defines and provides brief descriptions of several technologies related to media convergence: Wi-Fi, a wireless networking standard based on IEEE 802.11; PVR, which uses an onboard encoder to compress analog TV signals for recording; MP3, a patented digital audio encoding format; and Ethernet, a wired networking standard for local area networks. References are provided for each technology.

3. Wi-Fi Wi-Fi is a trademark of the Wi-Fi Alliance that may be used with certified products that belong to a class of wireless local area network (WLAN) devices based on the IEEE 802.11 standards.

4. PVR The Personal Video Recorder (PVR) range utilise an onboard MPEG/MPEG-2 encoder to compress the incoming analogue TV signals. The benefits of using a hardware encoder include lower CPU usage when encoding live TV.

5. MP3 MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a patented digital audio encoding format using a form of lossy data compression.

6. Ethernet Ethernet is a family of frame-based computer networking technologies for local area networks (LANs). The name comes from the physical concept of the ether.
