HD Broadcast Encoder with ASI Remultiplexing
HD Broadcast Encoder with ASI RemultiplexingMPE-4001
BLANKOM MPE-4001 combines MPEG-2/H.264 HD video encoding, professional audio interfaces and ASI remultiplexing. Two ASI inputs feed the multiplexer; encoded services leave through ASI and two independently addressed Gigabit IP interfaces.

Technical Overview
HDMI, HD-SDI and component video connect broadcast and production sources. The CVBS connection is specified for closed-caption use and must not be presented as an unrestricted additional video encoder input. Input timing and encoded output timing should be checked together.
The video encoder supports MPEG-2 HD/SD and MPEG-4 AVC/H.264 HD/SD, not HEVC. Its 2.5–19 Mbps range and CBR/VBR control target transport-stream distribution. GOP options and 4:2:0 sampling should be matched to the receiving broadcast chain.
Two ASI inputs allow external transport streams to be remultiplexed with the encoded programme. Two physical ASI output ports and two Gigabit Ethernet interfaces provide broadcast and IP hand-off. Independent IP addresses do not imply automatic hitless protection.

Typical Applications
Broadcast headend contribution
Encode an SDI production source as an MPEG transport stream for a compatible modulator or receiver. Select the audio pair and codec before allocating multiplex bandwidth.
ASI service aggregation
Combine external ASI transport streams with the local encoded programme. Plan service identifiers, PID allocation and total bitrate for the downstream output.
Parallel ASI and IP distribution
Supply broadcast equipment over ASI and a managed network over IP. Treat transport selection and network redundancy as separate engineering decisions.
