TYPICAL APPLICATIONS
DISPLAYING REMOTE VIDEO ON A WEB BROWSER
The NET104A transmitter uses Motion-JPEG video compression or high performance H.323 coding
for transmitting across the network. This enables transmission to standard web browsers of either
live video (Live Video mode) or a stream of still images (Server Push mode).
•To activate the Live Video feature, click Live Video above the video window on the PelcoNet
NET104A Transmission System home page (see Figure 6). The unit transmits using the H.323
coding format for display in the browser.
To stop Live Video, click any other option at the top of the page.
•To activate the Server Push feature, click Server Push above the video window on the home
page. The unit continuously grabs snapshots to be JPEG encoded, transferred, and displayed
continuously by the browser.
To stop Server Push, click any other option at the top of the page.
The PelcoNet NET104A Transmission System can display live video to an infinite number of users
at a time (multicasting) or up to five users at a time (multi-unicasting). A sixth user connecting to
the same transmitter in a multi-unicast configuration cannot receive live video. In a unicast
configuration, only one user at a time can receive live video.
Server Push can support multiple users simultaneously on the same transmitter. Image quality is
good with an update rate of one image about every 2 to 10 seconds depending on the number of
users and available bandwidth.
Browsers that do not support live video technology can display an updated still image or a stream
of images in Server Push mode.
