- 3. Video Conferencing Resolutions - Defined Minimum resolution and frame rate for transmitting high definition Source: http://en.wikipedia.org/wiki/High-definition_video
Notas del editor
- This is how video conferencing resolutions CIF, SD and HD are defined – and note that the minimum frame rate and reoslution for HD is 24fps at 1280x720
- For true interactive video conferencing, you need to do more than just provide a resolution. You need to maintain the frame rate during heavy motion, you need to provide HD video AND HD content, since video conferencing includes both. You need to send HD based on standard resolutions and definitions so that your system works with other HD systems in the market. This is why we have a standards body and why the vendors work so hard to adhere to existing standards When a customer invests in HD technology, they will likely invest in HD peripherals and create an HD environment – the HD codec and camera need to fit well inside that environment When not in an HD call, the HD system should be backward compatible with other systems on the network so that each system can be fully utilized.
- By definition, an HD codec will code and decode high definition video – maintaining the minimum frame rate even with a dynamic video image Additionally, an HD camera that can capture and send HD images is needed The codec should be able to support HD peripherals – either from the vendor (other cameras) or 3 rd party (other HD devices) The system should be able to “plug and play” with HD monitors – so that when a system is connected to a display, it chooses the highest possible resolution that is available to both the codec and monitor. In most cases for video conferencing, that will be 720p.
