Video Conferencing
H.323 Video over IP is typically transmitted at 30 frames per second. Traditionally requiring a T-1 circuit for digital transmission, this technology typically utilizes only a quarter or half of a T-1 per call — allowing additional bandwidth for other purposes such as E-mail or other Internet applications. High Defination video conferencing typically requires 2/3 of a T-1 per call and is transmitted at 720P or 1080P depending on the video unit’s capabilities.
Streaming Video
Streaming video differs from H.323 video in that participants are not able to engage in two-way interaction with the presenter. A Video Stream can be of a live video conference or of an Archived video
Where H.323 video conferencing is “Real-time” (meaning it is live with minimal delay), Video Streaming of a live conference will typically have between a 5 – 20 second delay depending on the available bandwidth to the computer.
Video Archiving
Video Archiving is the recording of video, audio and presentation data for playback at a later time. Such archived video can be embedded into a web page to be streamed out to anyone with a computer and/or stored on permanent media such as a DVD.
