How to Connect
Broadband, ISDN and LAN IP
ISDN has been the standard method of line connection for video conferencing since the 1970's. It remains in use today by thousands of organisations as it allows easy world-wide connectivity, but technology could be changing all this especially for companies who wish to communicate over an IP LAN.
The videoconferencing industry is diverging from its roots in telephone-based technologies and actively developing videoconferencing systems based on Internet Protocol (IP). In fact, industry observers say this switch in data-transmission technology, from traditional integrated services digital networks (ISDN) to IP, will be the biggest fundamental change in the industry during the next five years.
Q. Why use Video over IP?
A. video over IP has some significant advantages over traditional ISDN based solutions.
These include:
• Greater reliability and always on
• Offers ability to fix costs
• Significantly improved quality
• Fully scalable solution
• Enhanced Remote Managemen
• Enhanced security options
IP is the same protocol used for sending e-mails and transmitting data across the Internet. Since International Telecommunications Union (ITU) approved the H.323 transmission standard in 1996, videoconferencing over IP has become more widely accepted with each passing year. The H.323 data format, a compression algorithm that provides consistent packet transmission of audio, video and data across networks, is the standard for videoconferencing over IP.
Although traditional ISDN-based videoconferencing provides adequate data transmission and a natural viewing environment in optimal circumstances, videoconferencing using IP has several advantages that are pushing the trend in the industry. In addition to video and audio, IP makes it easier to integrate PowerPoint slideshows, HTML-based presentations, animation and other media into a videoconferencing environment. Videoconferencing on IP will also allow faculty to manage most or all of their communication technology on a single network. In addition to eliminating the per-minute long-distance calling rates associated with ISDN, this convergence will help users focus on a single technology platform.
