Video Conferencing takes the HD route

Just as e-mail revolutionized the way in which we communicate, High Definition video conferencing is opening up possibilities in communication and information sharing that make virtual meetings as easy, life-like and efficient as they can possibly be. By Manjari Juneja

High Definition (HD) Video conferencing is fast becoming the most acceptable form for video communication. It is the most realistic technique to conduct collaborative meetings eliminating the need for costly, time consuming and environmentally-hazardous travel.

It gives nine times better video quality during video teleconferencing. This technology would eventually replace existing video teleconferencing systems. The fundamental reason why people do video conferencing is to see the other participants clearly and hence, any technology that provides substantially clearer video would be a big hit.

According to a report from Frost & Sullivan, telepresence and video conferencing are poised to grow into a $4.7 Billion industry worldwide by 2014, out of which Asia Pacific is expected to contribute $1.7 Billion.

"Interest in video has never been greater, and HD technology is the driver. In just over three years since LifeSize delivered the world's first HD video system, high definition is the overwhelming choice"

- Shivashankar K
Country Manager - India,
LifeSize Communications

"High-definition technology broadens the quality and range of information communicated through VC to create a valuable communication tool for
businesses, distance learning, enterprises, telemedicine and government alike"

- V Praveen Kumar
Head UC Business, Avaya Global Connect

"HD Video has been there for a while and has seen consistent traction with enterprises and mid market companies. Superior video quality coupled with HD Voice enhances the overall user experience thereby increasing enterprise-wide adoption and usage"

Neeraj Gill, Managing Director, Polycom India & SAARC, said, “HD Video has been there for a while and has seen consistent traction with enterprises and mid market companies. Superior Video Quality coupled with HD Voice enhances the overall user experience thereby increasing enterprise-wide adoption and usage.”

Shivashankar K, Country Manager – India, LifeSize Communications, said, “Interest in video has never been greater, and HD technology is the driver. In just over three years since LifeSize delivered the world’s first HD video system, high definition is the overwhelming choice.”

Inside HD technology

High-definition video conferencing is a two-way, interactive process that transmits audio and video data in real-time, back and forth across a network. To achieve high-definition video conferencing, all endpoints in the conference must be high-definition enabled.

High definition video conferencing works by transmitting live images using hi-spec cameras and flat-screen video displays, while broadcasting sound through top-of-the-range speakers. It allows people to communicate through high quality video and audio and share media files such as documents and presentations.

It uses the highest picture resolution possible, more than four times that of a regular television screen. This gives high definition video conferencing a quality and clarity of picture that is unsurpassed, eliminating blurry outlines, washed-out colors and visual noise. Users can switch manually or using voice-activated technology between screens, viewpoints and cameras, and share presentations, documents, and multimedia with other attendees.

The big advantage of high definition video conferencing is that, unlike traditional video conferencing systems, which could suffer from blurry or pixilated images, high definition video conferencing gives a crystal-clear picture and smooth motion perfectly synched with the audio.

V Praveen Kumar, Head UC Business, Avaya Global Connect, said, “Video Conferencing enables geographically dispersed people to come closer to collaborate effectively on a real-time basis. It essentially makes the world a much smaller place by connecting colleagues, stakeholders, customers, friends, prospects across the world in real-time on a daily basis. High-definition technology broadens the quality and range of information communicated through VC to create a valuable communication tool for businesses, distance learning, enterprises, telemedicine and government alike.”

Market for HD VC in India

The Indian audio-video-Web conferencing industry continues to be on the growth path especially in these troubled times as these technologies help in reducing costs and increasing employee productivity.

HD video conferencing is becoming an essential tool to help enterprises save on travel costs at the same time as enhancing communications with face-to-face meetings that enable improved collaboration. SMEs in India are transforming themselves into global players by effectively using information technology to improve their businesses and manage costs.

Video technology has matured and HD technology has advanced so that conferencing is now considered a fundamental tool in many organizations’ communications infrastructure. At the same time, IP networks have become more robust and affordable, while advanced video codecs deliver greater performance.

576p 24, 25, 50 414,720 (720 X 576) 4:03 SD
720p 24, 25, 30, 50, 60 921,600 (1280 X 720) 16:09 HD
1080i 25, 30 2,073,600 (1920 X 1080) 16:09 HD
1080p 24, 25, 30, 50, 60 2,073,600 (1920 X 1080) 16:09 HD

Many large enterprises are choosing HD videoconferencing solutions as they are cost-effective, easy to use and save time for enterprises.

According to Frost & Sullivan the videoconferencing market in India is growing 23% year on year. Due to the high and growing demand from the government sector, India had emerged as the fourth largest market for videoconferencing end-point equipment in the APAC region.

According to Frost & Sullivan, the total market size of the unified communications in India was around $670 million in 2008 which is likely to grow to over $1 billion by 2010. It also stated that the BFSI and IT/ITES sectors were continuing to invest in video communications, along with organizations in education and healthcare.

Sanjay Bansal, Founder, Chairman of the Board & Managing Director, Business Octane, said, “More than 60% of new purchases are HD systems and Business Octane has also launched a value replacement offer for which customers get an attractive buy-back value for their old standard definition systems which are replaced with HD systems.”

Hurdles faced by adopters of HD video conferencing in India
Infrastructural issues and cost Bandwidth quality and its cost continue to be a barrier to the adoption of HD VC in the enterprise
Lack of Awareness There continues to be a perception that deploying videoconferencing solutions is capital intensive, more so HD videoconference solutions that cost even more. However, this is only a perception and no longer true

Challenges

Rajesh KK, Business Development Manager, TelePresence Systems, Cisco India & SAARC, said, “Internet-based connections are increasing in popularity and many public rooms have come up in India, which allow these conferencing over IP network. Bandwidth issues at the backend also need to be addressed to ensure that full benefits of the technology can be availed by a larger section of the targeted user base.”

Quality of service is vital for a video conferencing solution and the same can be achieved with the optimum bandwidth. A minimum bandwidth of 1 Mbps is required for high definition video conferencing. Organizations should reserve roughly 20% of network bandwidth (via traffic prioritization) for real-time video conferencing, as a starting point. As the deployment across the enterprise proceeds, one can adjust this up or down to fit the adoption and usage patterns that emerge.

Sanjay Virnave, President Sales, Tulip Telecom, said, “Video conferencing as a solution offering has found many takers, specially the government sector has emerged as a major client. Apart from regulatory and other functional challenges, VC as a technology has very limited successful demonstrated setups in the Indian context, which results in greater skepticism and initial inertia for mass adoption. Moreover, there is lack of education and low awareness on the business benefits of conferencing solutions. Factors like cost of ownership, maintenance of infrastructure, and the general perception about videoconferencing as an item of luxury could possibly impact the growth of this market.”
