- ATM DS3 (44.736 Mb/s) on coaxial cable.
- ATM E3 (34.368 Mb/s) on coaxial cable.
All ATM interfaces are capable of classical IP over ATM (CIP), RFC 2684 bridge
mode, and native ATM over AAL-5 operation, all in PVC mode.
The OC-3 interfaces support the full VPI/VCI range of 0-255/0-4095 and offer
traffic shaping features; the DS3 and E3 interfaces only support UBR mode and
are limited to the VPI/VCI ranges of 0-7/0-511.
Real-Time MPEG-2 Encoder Plus (RTME Plus)
The RTME Plus supports four channels (two stereo pairs) of audio for encoding
into either MPEG-1 Layer II or Dolby Digital (AC-3) audio. The audio source can
come from any of the following input interfaces: unbalanced, balanced, AES or
embedded Serial Digital Interface (SDI). The encoder supports analog and digital
video sources. For an analog video signal, S-Video or composite video inputs are
available for configuration. Alternately, the encoder can receive digital video input
through the SDI.
Real-Time MPEG-4 AVC Encoder (RTME MPEG-4 AVC)
The RTME MPEG-4 AVC Encoder offers other audio encoding options and
MPEG-4 video. The audio source can come from any of the following input inter-
faces: unbalanced, balanced, AES or embedded Serial Digital Interface (SDI). The
encoder supports analog and digital video sources. For an analog video signal, S-
Video or composite video inputs are available for configuration. Alternately, the
encoder can receive digital video input through the SDI.
Real-Time MPEG-4 AVC Ultracompression Encoders
The Real-Time MPEG-4 AVC Ultracompression Encoder submodule has two fac-
tory-installed input option cards: a Standard Definition input card and a High Def-
inition input card. Accordingly, these ultracompression encoders are provided:
•
MPEG-4 AVC Ultracompression HD Encoder. This encoder can accept HD-SDI and SD
Interface input signals (on the same physical BNC interface).
•
MPEG-4 AVC Ultracompression SD Encoder. This encoder can accept SD signals. The
interface options are Composite, S-Video, and Serial Digital Interface (SDI), in the exact same
arrangement as the MPEG-2 Encoder Plus and the H.264 MPEG--4 AVC Encoder.
Both encoders can receive video through a variety of input interfaces and com-
press it to MPEG-4 Part 10 (H.264).
The encoders support up to six audio stereo pairs, depending on the selected audio
compression scheme. The first two audio pairs can be analog-balanced or unbal-
anced signals, connected through the 37-pin micro-D connector. When using AES
NOTE
HD operation requires a license key.
