subject: Hd Video Conferencing [print this page] With the rising cost of travel expenses, video conferencing offers a cost effective method of having face to face time with friends and clients without leaving your desk. Video conferencing is not a new idea, but new technology allows users to experience the clarity of high definition video while communicating across the country, or across the globe. HD video conferencing offers users a more personal and lifelike video conferencing experience compared to traditional video conferencing solutions.
HD video conferencing allows details to be transmitted over the Internet that can have a significant impact on the members of the conference. People that use technically detailed diagrams or high resolution photos during a conference will know that the information that they are trying to send will be received by all parties. When a group of people are taking part on one end of a conference, HD video capability allow all members in the group to make sure that their message and presence is being sent out with everyone else in the group, while SD conferencing only allows has the video capacity for one user of a time. Even the subtleties of facial expressions can be transmitted with high definition video conferencing allowing a very true to life experience.
Some factors to take into account when selecting an HD video conferencing system is the power of the systems that will be a part of the video conference. HD video images can be considerably large in size when compared with traditional SD video conference images. The conferencing system has to have a camera that can take video that is up to 1080 lines high. Many laptop and desktop web-cameras only capture video at a resolution of 480 lines high. Another issue is the image frame rate. True high definition video is captured at a rate of up to 60 images a second in order to send a true HD stream to the other computers in the conference. Some laptop computers and older desktop computers can not process images that quick even using a true HD camera.
One way to ensure true HD video conferencing performance is to buy a dedicated HD video conferencing system. Standalone systems that are designed to capture, processes, and transmit audio and video signals in high definition could be the best way to insure a reliable HD video conferencing experience. The other issue is to make sure a HD video stream is being sent and received by all computers over various networks. In order to accomplish this, a broadband Internet connection that has a fast download rate, but also a fast upload rate is also required. A 1 megabit per second connection (both upload and download) or better is required by all members of the conference for true HD video quality. If all of the software, hardware, and network requirements for HD are met, HD video conferencing can give people a near real life meeting experience with out the hassle or expense of travel.
