TREAMING
Streaming refers to the continuous transmission of media (video, audio and/or data)
in one direction. Unlike videoconferencing, which requires realtime, two-way
transmission with sufficient bandwidth, successful streaming has less stringent
transmission requirements. Streaming may take place whether or not the HD3000 is
engaged in a call.
Multicast and unicast streaming are available for HD3000 users:
A multicast stream refers to the same stream simultaneously sent from one
terminal to more than one client.
A unicast stream refers to one stream being sent from one terminal to only one
client.
The transmitted media is not stored on the client computer. Instead, the client's
viewing application runs the stream as it collects and processes it, even if the client
is still receiving the stream.
To view streams, Emblaze VCON's Broadcast Viewer or Apple's
QuickTime Player must be installed on the client computer.
Using Emblaze VCON's HD DualStream™, the HD3000 can send a video and data
stream simultaneously. HD DualStream enables video transmission using the
H.263 codec in CIF, and data transmission (as video images) using H.263 at 4CIF
resolution. If the viewing client's conferencing system or PC supports 4CIF, the
data images appear in 4CIF. Otherwise, the data displays in CIF.
