Hi mohammad
- Video Conference (or sometimes written videoconference) is the most common term for video communication. It replaced the term "videophony" which was somewhat redundant, even though we will meet the “tele” segment again. A video conference is the form of any communication using image and audio of two or more locations, exchanging data in real-time and in all directions at the same time.
- Telepresence is the “new term” for video conferencing. However most people would agree that the term telepresence includes only high-end codecs that support high bandwidth and provide HD resolution.
TelePresence is really an entirely new techonlogy and surpases video conferencing in these ways:
- Quality and "environmental factors". It combines life-size video images that have ultra-high definition claity and CD-like audio. And, meeting participants actually feel like they are sitting a the same table, making eye contact, and talking to or over each other. Just like a person-to-person meeting.
- Simplicity. Super simple and user-friendly. It uses your enterprise calendar (like Outlook) to schedule meetings, and you just press a button on the phone to start a call. Very little training needed because these are tools you use every day.
- Reliability. Takes advantage of a highly available network and the Unified Communications infrastructure to offer users high reliability
