As we told you some time ago, Avalpa people gave a talk at last DvbWorld 2010. It was quite a rewarding moment after all the efforts of the last 6 years. Thank to the committe people for the invitation.

Here there's the presentation. I hope you'll enjoy it: beware, you'll find some spicy words.. i did want people in the audience to stay awake, and after the lunch it's always a difficult task! ;-)

Television is going digital. We have the mission to improve it, with advanced, better, simpler, more dynamic technologies in a free software sauce. Avalpa is the next step..

The IDTVOS project is finally public. IDTVOS is the free middleware for digital television set top box developed by Inteco.

IDTVOS is based upon Jet and is focused toward easy accessibility (useful for everybody and impaired people too!). The main feature inside is the integration with Flite, a "text to speech" engine that help a lot browsing the decoder menu, reading televideo and all the textual content already present in interactive applications.

OpenCaster is a free and open source MPEG2 transport stream data generator and packet manipulator.

New manual 1.2 is available here: manual

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.
