Basic Setting
GOP provides users with the function to set the pages of the I Frame and P Frame to be
transmitted in the MPEG4 mode. Basically, the I Frame page contains the entire picture and
needs higher bandwidth, while the P Frame page only contains the parts that are different from
the I Frame and needs lower bandwidth. Hence, when you need to transmit the pages without
disruption in a normal network environment, you can set up a higher GOP. For example, if GOP
25 is selected, 24 P Frame pages will follow 1 I Frame page, and so forth. However, packets
may be lost when they are transmitted in a congested network environment. In this case, the
following P Frame pages may bring about disruption of the transmission because they lose the
reference upon which the difference from the I Frame is identied. You may change GOP to 10
with this concern to avoid disruption of the transmission. The GOP is 15 by default.
