Nevion CP505 ATSC Processor

The CP505 ATSC Processor offers flexible ASI, SMPTE 310 and IP network adaptation and advanced Transport Stream processing in a user-friendly and compact 1RU solution.

The CP505 provides a powerful solution for adaptation of MPEG Transport Streams to ATSC broadcast and other transport stream processing applications. The CP505 is offered in two different variants.

The basic model provides format conversion between ASI, SMPTE-310 or Transport Stream on IP/GigE (electical 1000Base-T or SFP), STM-1/OC-3 or E3/T3-DS3.

The advanced model offers the basic features plus powerful PID and program filtering with ATSC PSIP and DVB SI processing capabilities.

The CP505 supports dynamic PSIP generation for electronic program guide data, interfacing to EPG providers via the ATSC standard PMCP XML-based interface via HTTP or FTP connections. The CP505 has succesfully been integrated with several PSIP data providers, including MediaStar PSIP from Broadcast Interactive Media.
