TYPICAL APPLICATIONS
DISPLAYING REMOTE VIDEO ON A WEB BROWSER
The NET4001A uses MPEG-2 and MPEG-4 for transmitting audio and video 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 NET4001A transmission system home
page (refer to Figure 3). The unit transmits using MPEG-2 or MPEG-4 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 PelcoNet NET4001A transmission system
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 NET4001A transmission system can display live video to an infinite number of users at a time (multicasting).
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.
