Abstract

Research Overview

This Frost & Sullivan research service titled Strategic Analysis of High Definition (HD) Technology and its Impact on Videoconferencingprovides an overview of HD technology and its benefits and challenges in the videoconferencing market. In this research service, Frost & Sullivan's expert analysts thoroughly examine HD videoconferencing technology and analyses its impact on the videoconferencing market.

Market Sectors

Expert Frost & Sullivan analysts thoroughly examine the following market sectors in this research:

By application:
  • Videoconferencing
By Technologies:
  • High Definition (HD) and H.264
Technologies

The following technologies are covered in this research:
  • High Definition Television (HDTV): It is an innovative set of standards for television that brings about noticeable improvements in picture quality. This is the first change to the television format since color replaced black and white television. The generally agreed upon definition of high-definition television is that it possesses roughly twice the vertical and horizontal picture resolution of analog, which essentially makes the picture twice as sharp. HDTV also has a screen ratio of 16:9 as compared with most of the present day TV screens, which have a screen ratio of 4:3.
  • H.264: H.264 is a compression digital video codec standard. This standard is similar to ISO MPEG-4 part 10, and is also known as AVC, for advanced video coding. H.264 contains features allowing it to compress video more effectively and to provide more flexibility over different networks. Overall, H.264 performs much better than other standards. H.264 is more efficient than MPEG-2, providing the same quality with only half of the bit rate or even less.
Market Overview

High Definition (HD) Technology Promises Enhanced Video Conferencing Experience

Confronted with interoperability issues, the videoconferencing industry, over the last ten years, has progressed towards developing industry standards. Most vendors have adopted these standards as a common denominator in order to collectively encourage overall market growth. In line with these developments, vendors continue to enhance the total videoconferencing experience, paying greater attention to improving audio and video components. Considering that improvements to these two elements, from both a hardware and software perspective, will deliver a greater overall experience, many believe that HD technology could well be instrumental in boosting the adoption and utilization rates among videoconferencing end users.

The HD component is the latest technological addition to the overall videoconferencing market. HD technology on its own offers a higher quality visual experience, which is a key element in videoconferencing. In addition to video, audio is an integral component of the conferencing experience and high fidelity audio along with HD has the potential to create a richer videoconferencing experience for the end user "The key benefits of HDTV from a viewer’s perspective are enhanced realism from improved picture and sound quality," notes the analyst of this research service. "Further, these enhanced features create an avenue for end users to embrace videoconferencing as a critical business communication tool."

Non-proprietary Solutions Critical to Success of HD Technology

One of the early plagues in the videoconferencing market was with vendors utilizing propriety algorithms, causing interoperability issues. As this impeded growth, vendors will need to develop non-proprietary solutions in order for HD technology to materialise as the next generation technology in the videoconferencing market. "A combination of concurrent technological innovations now makes it possible to bring HD video and audio to videoconferencing and with rapid growth in IP network deployments" says the analyst of this research service. "Moreover, with the proliferation of IP networks, the market is ready to accept new video advancements such as HD".

Videoconferencing equipment vendors are taking various approaches to HD videoconferencing. "While some have developed HD endpoints including a camera to offer a full HD videoconferencing solution, others are upgrading their infrastructure and endpoints with software to handle the compression," says the analyst. ‘Although, no hardware upgrades have been released till date, it is anticipated that most videoconferencing vendors will develop an HD hardware offering by mid 2006."
