New 2.4 features:

• Basic input remultiplexing
• BISS support

New 2.2 features:

• AC3 encapsulating and multiplexing support for 5.1 sound
• enhanced DVB-SSU
• old but ever green teletext over DVB

New 2.0 features:

• seamless playout of off-line MPEG2 encoded videos
• IP multicast driver for IPTV services
• successfully integrated with products by Cisco/Scientific Atlanta, Ericsson/Tandberg, Eurotek, Harmonic/Scopus, Mitan, MainConcept, Screen Service
• tested with Rohde & Schwarz DVM100L,

What you can do with OpenCaster, the straight list:

• create PSI/SI tables
• play out seamlessly every kind of file (data, audio & video when properly encoded)
• manipulate real time TS stored on hard disk.
• transform filesystems in DSMCC carousels (MHP, MHEG, OTA)
• generate many other data streams carried on a TS; almost everything but audio and video, that's because OpenCaster IS NOT AN MPEG AUDIO/VIDEO ENCODER.
• multiplex constant bit rate transport (CBR) streams
• restamp PCR, PTS & DTS
• output to DVB-ASI with PCI and USB hardware boards (today in house Computer Modules, Dektec, Bluetop).
• output to DVB-S, DVB-T and DVB-C with Dektec DTA110T hardware boards.

Audio and video streams are expected as input files in a transport stream TS format or as elementary streams ES and then can be transformed to TS format at any bitrate with local PCR stamping.

OpenCaster ver 2.2 has been released the 11 of September 2009

New features:

• AC3 encoding and multiplexing support for 5.1 sound
• enhanced DVB-SSU
• old but ever green teletext over DVB

OpenCaster ver 2.0 has been released the 13 of June 2009

New features of this 2.0 release:

• seamless playout of off-line encoded videos
• transport stream over IP support for IPTV services
• updated pdf manual with something like one hundred page

the first feature is the one who accounts for a major bump up! now OpenCaster can play out not only PSI/SI tables and data carousels but also audio and video files in a seamless and continuous stream for a really complete digital television solution.

BTW also real time event insertion is supported albeit it's a bit tricky and acually not for the faint of heart!

OpenCaster ver 1.0 has been released the 20 June 2008

This time we made a better packaging with:

• a light source files tar,
• a huge tutorial fileset,
• TADAA!! a properly formatted manual.
