1.0.1 Video
The HE4000 has two video encoding engines that can be used individually or simultaneously.
The input video follows either the standard definition 4:2:0 Main Profile @ Main Level or the 4:2:2
Studio Profile @ Main Level, and high definition 4:2:0 Main Profile @ Main Level or 4:2:2 Studio
Profile @ High Level according to MPEG-2 standards (ISO/IEC 13818-2).
The HE4000 supports the following compressed video rates:
Standard Definition
•
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,
High Definition
•
MPEG 4:2:0 Main Profile @ High Level up to 80 Mbps
•
MPEG 4:2:2 Studio @ High Level up to 160 Mbps
The HE4000 accepts the following video input:
Standard Definition
•
SDI (SMPTE-259M)
•
Composite (PAL or NTSC)
High Definition
•
SDI (SMPTE-292M)
The video encoder features a low latency mode for interactive applications and a
ComtechTV proprietary, high-quality horizontal resampling filter for intermediate horizontal
resolutions.
