IP-900 Series

1.1 Main Features
IP-900 series is a video encoder that uses the high compression video encoding technology H.264. It
enables real-time streaming of high definition (HD) and standard definition (SD) video through the
optical fiber networks like FTTH.
The IP-900E can operate as an encoder and the IP-900D/IP-900IID can operate as a decoder. When
operating as an encoder, the IP-900E encodes input video and audio signals into the H.264 format and
distributes the results over an IP network in real-time processing. When operating as a decoder, the
IP-900D/IP-900IID decodes encoded data received over an IP network and outputs the results as audio
and video signals. In addition, the IP-900E operating as an encoder provides a recorder function (*1),
which allows HD video data to be transmitted over a longer period of time even when the network
bandwidth is low.
IP-900E encoder also features simulcast (dual encoding) capability to distribute two kinds of the
encoded streams that are produced from a single video input by main and sub encoder of IP-900E in
real-time.
Table 1-1 IP-900E Specifications
The main HD video and sub HD video functions become available when the HD option is added.
