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 pictur e 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 identified. You may change GOP to 10 with this
concern to avoid disruption of the transmission. The GOP is 15 by default.
