Why High Definition? - A laymans guide

Picture Definition

720p High Definition achieves 9x the detail that CIF standard achieves, 36x the detail that QCIF delivers and 48x the detail that standard webcams deliver.

Achieves clearer, sharper pictures and avoids the need to move the camera as much to see all the participants, avoiding blur from camera movement. 

It is also a true widescreen format, so fills Plasma & LCD displays without cut-off, black borders and distortion from stretch.

Picture Motion

720p High Definition systems from TANDBERG & Polycom achieve 30 frames per second video, making movement fluid and clearly defined.

In comparison, many webcam applications only achieve 5 frames per second or less, making movement  stutter or freeze.

Sound

TANDBERG & Polycom High Definition systems can achieve CD quality (20Khz stereo) sound - the industry standard is 7Khz mono.

Benefit from sharper, clearer sound as well as picture! 

Interoperability

High Definition systems from TANDBERG & Polycom will also connect to Standard Definition Videoconference systems, so you can retain compatibility with other users, or upgrade in stages. Be careful, not all HD systems are compatible with other units!
