It’s an exciting time in the video communications industry. HD video is obviously now the industry standard, replacing the traditional, standard definition (low-quality) video conferencing as a far superior technology. The quality, simplicity and manageability of this medium, combined with wide availability and lower costs of HD displays and IP networks, promise far greater usage and value than the staid video conferencing of old.
The benefits of HD video are easy to realize – clear, crisp picture quality leads to an authentic, “just-like-being-there” experience that’s totally addictive. Adopters to the technology see reduced travel costs and increased daily collaboration beyond the limits of audio conferencing, email and instant messaging.
Yet despite the proven benefits, there is still some reluctance to make the move to HD. In this seven-part blog series, we’ll discuss these common misconceptions and try to squash them.
Myth 1: High quality video communication requires way too much bandwidth
Fact: To achieve high definition video (that’s 1280×720 at 30 frames per second,) only 768Kbps is needed. For even better motion handling, 60 frames is achievable at 1.1 Mbps. For some perspective, your office’s standard T-3 line has an output of about 43.23Mbps. A T-1 line emits 1.54Mbps. However, not all video vendors are created equal in technology and interoperability.
Additionally, measurable increases in quality at lower bandwidths can also be obtained. For example, DVD quality is achievable at just 384Kbps. So, for less than 1Mbps over the public Internet, phenomenal video quality is now a reality. Most businesses are capable of allocating this amount of bandwidth for video communications, especially when the cost-to-return component is so favorable. In some cases it is desirable to use a QoS (Quality of Service) network, but it’s not always imperative.
