Overview SE4000 MPEG-2 Contribution Encoder
1-2 01-0934-401-B
1.1 Video
The SE4000 uses an advanced video compression ship-set which encodes the input video
following either the 4:2:0 Main Profile @ Main Level or the optional 4:2:2 Studio @ Main Level,
according to MPEG-2 standards (ISO/IEC 13818-2).
The SE4000 supports the following compressed video rates:
•
MPEG-2 4:2:0 Main Profile @ Main Level: 1 to 15 Mbps
•
MPEG-2 4:2:2 Studio Profile @ Main Level (optional): 2.5 to 50 Mbps, which provides
superior quality compressed images at high data rates.
The video encoder features a low latency mode for interactive applications and a Tiernan
proprietary, high-quality horizontal resampling filter for intermediate horizontal resolutions.
1.2 Audio
Two stereo or four mono audio channels are compressed using MPEG or AC-3 2.0 audio
encoding standards.
The SE4000 supports compressed audio output rates of 64 to 384 Kbps and four different audio
channel compression methods.
1.3 Auxiliary Data
One channel of synchronous data up to 20 Mbps (RS-422) and one channel of asynchronous
data up to 115 Kbps (RS -232) are supported by the SE4000.
1.4 Conditional Access
The SE4000 optionally supports BISS, Modes 1 and E, as well as Tiernan’s proprietary
conditional access schemes.
1.5 VBI (Vertical Blanking Interval)
Extensive VBI data support is provided via the SE4000. Supported formats include:
•
Proprietary passage of NTSC line 21 closed-caption.
•
ATSC closed captioning.
•
DVB Teletext for World System Teletext (WST) on PAL.
•
DVB 4:2:2 expanded windows carries WSS, VPS, VITC, CC, AMOL, XDS, etc.
1.6 Modulator
The SE4000 has a built-in DVB
®
-compatible QPSK, 8PSK and 16QAM modulator with a 70 MHz,
140 MHz, and direct L-Band output carrier capable of supporting up to 45 Msps. An L-Band
monitor output is provided for direct IRD connection.
1.7 Modulator Control Buttons
The SE4000 provides dedicated modulator control buttons on the front panel. These are
designed to bring carriers up onto satellites in a fast and efficient manner.
