video conferencing

Stickiness grows Economic considerations drove some quick adoption but a range of benefits and richer experiences are making users stay By Prachi Shirur

rganisations today are looking at cost-effective and time saving means to enhance productivity and reduce cycle times. Governments are no exception to that. Video conferencing is one such tool that helps them achieve these objectives, offering ‘face-to-face’ communication between two or even more locations. In fact, the economic slump last year helped the video conferencing market, with more and more organisations opening up to the technology that they had earlier turned down as difficult-to-use and insufficient. With budgetary constraints and reduced or restricted travel budgets, video conferencing has picked up as an alternative to face-to-face meetings. Video has transitioned from its historic limitations to become a mission-critical component of unified communications (UC) too. It has reached the 3G mobile applications arena including streaming, instant messaging and scheduling. It is offered over both Integrated Services Digital Network (ISDN) and Internet Protocol (IP) networks. As per market research firm BizAcumen, improved flexibility, seamless integration with other applications, enhanced reliability and lower cost of networks are propelling the

video conferencing industry to adopt video conferencing based on IP networks. Primarily, three types of video conferencing solutions are being used: room-based, telepresence and desktop-based. A combination of these is also often used. Meanwhile, some major telcos as well as system and service providers have emerged as significant players in the video conferencing market, globally.

Standards and interoperability There are certain umbrella standards for

videoconferencing, as recommended by International Telecommunications Union (ITU). H.320 is the ITU recommendation for videoconferencing over ISDN, while H.324 is for transmissions over analogue phone lines. The H.323 standard is suitable for a mix of IP, PSTN and ISDN networks. H.264 SVC (scalable video coding) is a compression standard that enables video conferencing systems to achieve highly error resilient IP video transmission over the public Internet without quality-of-service enhanced lines. This standard has enabled wide scale
