Axcera demonstrates ATSC M/H Preprocessor/Multiplexer at NAB
Axcera will demonstrate its complete end-to-end ATSC Mobile DTV transmission solution at NAB Booths C8546D and C1319. The company’s new ATSC Mobile DTV Preprocessor/Multiplexer (MHPM-A) combines terrestrial and mobile content along with an ESG into a single transport stream, feeding an ATSC broadcast transmitter with the AxciterTM adaptive digital television modulator, which will deliver Envivio-encoded content to a mobile receiver.
Designed from the ground up to the ATSC Mobile DTV specification, the MHPM-A Preprocessor/Multiplexer accepts both an ATSC fixed DTV data stream (A/53 standard) as an ASI input (SMPTE 310 optional) and an ATSC M/H DTV data stream (A/153 Standard) as MPEG-4 IP encapsulated data through a standard 10/100Mb/s Ethernet connection.
The two streams are processed, combined and then sent to an ATSC mobile-compliant (A/153) ASI stream. This stream can then directly feed any ATSC A/153-compliant postprocessor/modulator in a single-transmitter DTV broadcast system, or multiple DTV transmitters in an ATSC distributed transmission system. The MHPM-A's remote management interface is provided via an Ethernet connection, accessible from a standard Internet browser.
