• Bandwidth requirements are higher to allow more detail in video images
• Video-conferencing requires higher resolution video because there are often
several people on screen at once
• Need to see facial features/body expressions of participants clearly
• One person to another (when video-conferencing) does not require high
resolutions
• High bandwidth (of 2–4 Mbps) would deliver an (H720p) high definition
image for multiple participants
• Low bandwidth (of 512 kbps) would be sufficient for one-to-one videoconferencing
• Low bandwidth does not allow high definition images so would not be able
to properly see the faces of multiple participants
• High bandwidth would allow higher frame rates/30fps for smooth motion
• Limited/low bandwidth requires trade-off between resolution and frame rate
• Resolution priority for displaying slideshows/documents in detail
• Motion priority for displaying video presentations.
