ATSC-M/H Emission Multiplexer

Model: AEM100

  • All the requirements laid out in the ATSC Mobile DTV A/153 standard are met, in particular:
  • Complete implementation of complex error protection algorithms (Reed-Solomon and turbo codes) that make the transport stream robust
  • Complete generation of the standard-specific signaling and optional service information required for operation (baseband signaling)
  • Network-based clock synchronization
  • ATSC time with high-precision profile

The R&S®AEM100 ATSC-M/H emission multiplexer is a key component for ATSC Mobile DTV (MDTV). Its compact dimensions make it the ideal way for network operators to expand existing ATSC transmitter networks quickly and reliably by adding mobile services, or to set up a new network. It provides the entire functionality specified in the A/153 standard.

The R&S®AEM100 uses an ATSC transport stream and new video/audio data to generate a multiplex for mobile reception. The new video/audio data streams are encoded in accordance with the standard and linked to the main ATSC content. The R&S®AEM100 enables users to set up powerful, frequency-efficient single frequency networks (SFN) and ensures excellent uptime owing to seamless redundancy.

This user-friendly instrument is only one height unit high. The user interface makes operation simple and convenient.
