Appendix - Usage Model 2a: Lightly Compressed Video Streaming throughout the home
Pre-Conditions:
User has operational WLAN network which includes a TV with wireless capabilities, a PVR with wireless capabilities, and an AP associated with the WLAN that is not in the same room as the game machine and TV.
Application:
User can display the output of the PVR wirelessly on the TV using a video codec like Motion 2000 JPEG that lightly compresses video.
Environment:
Two story, three bedroom house with an AP in one corner in the den. Other homes in the area are also operating WLANs. Transmissions are mostly Non-LOS. Distance between far corners of the home are ~100 feet with as many as 8 walls (and one floor) between the video end points.
Traffic Conditions:
Occasional interference from other homes because WLAN is on other channels. Data transfers consuming up to 20% of the total bandwidth, 2 additional video streams, and wireless display/controllers from a video game machine may be occurring during this use case. Microwave may be running for up to 5 minutes.
Use Case:
User looks up a program on electronic program guide.
User selects a video.
Lightly Compressed Video is delivered/uploaded over the wireless network for a period of two hours.
User may pause video during 2 hour period then resume watching.
Task is complete when user stops watching the video.

Appendix - Usage Model 2b: Compressed video streaming in a room or throughout a home
Pre-Conditions:
User has operational WLAN network which includes a TV with wireless capabilities, a PVR with wireless capabilities, and an AP associated with the WLAN that is not in the same room as the game machine and TV.
Application:
User can display the output of the PVR wirelessly on the TV using high definition compressed video with a codec like BluRay . Expect three or four simultaneous HD streams.
Environment:
Two story, three bedroom house with an AP in one corner in the den. Other homes in the area are also operating WLANs. Transmissions are mostly Non-LOS. Distance between far corners of the home are ~100 feet with as many as 8 walls (and one floor) between the video end points.
Traffic Conditions:
Severe interference from multiple streams in the house and other homes because WLAN is on other channels. High speed data transfers consuming up to 20% of the total bandwidth, many additional video streams, and wireless display/controllers from a video game machine may be occurring during this use case. Microwave may be running for up to 5 minutes.
Use Case:
User looks up a program on electronic program guide.
User selects a video.
Compressed Video is delivered/uploaded over the wireless network for a period of two hours.
User may pause video during 2 hour period then resume watching.
Task is complete when user stops watching the video.
