SWITCHING STREAMING VIDEO
When using the multicast transmission, it is possible to switch the streaming video displayed on the monitor using the
following CGI commands. When using the unicast transmission, change the settings on the VIDEO page.
■ Format
■ Response
■ Important Notices
• It is necessary to enter "decode=start& ch=(parameter value)&address=(parameter value)".
• When not designating "enc_addr=(parameter value)&address=(parameter value)", it will take up to 500 ms to switch
streams. To switch streams smoothly, request the first stream to the encoder. In this way, it will take within 150 ms
to switch streams.
