Hello everybody.

I'm very happy to say that my OTVA project is going to be released in veeeery pre alpha version.

Is still a rough project but i'm going to tune it up.

here's the link: http://sourceforge.net/projects/otva/

What's OTVA? It's a MAM (madia asset management system) going from ingesting the media from your editing/video capture stations, to the playout on multiple channels (DVB-muxes) passing trough tagging of media, searching and scheduling.

'till now i made the system setup tool, the ingesting tool and the scheduler (all are very a prototype) using and open source programming language named GAMBAS http://gambas.sourceforge.net/

playout channels are based on the MLT (open source) project: http://www.mltframework.org/

My idea was to bound the avalpa EPG to feed DB with data provided during ingesting stage and synch the epg scheduling with the media playout .... stay tuned.

Cheers.

Federico

Hello Federico, your OTVA project scope is very interesting!!

The EPG integrated generation would be absolutely feasible, as the playout has complete knowledge of what's gong on, which are the relevant content to show in the info tab and what's only "jingle" or advertisement and so on (and should not put on EPG guide, of course)..

technically speaking, how are you doing with TS generation?

are you already be able to feed a DVB modulator? maybe the cheap USB Dongle from Hides will be key here for mass deployment..

BTW i'm not very fond on the MLT framework. is it working solid on TS generation?

what about CBR compression and PCR generation. after a fast lookup, i just see an old 2009 thread:

http://www.mltframework.org/bin/view/ML ... eBroadcast

it's still slightly disapponting :( , but i think 4 years are passed and maybe everything is ok, now. isn't it?

let us know how are you going, of course..

Hello A.Venturi :D

I'm not managing TS at all.
I'm collecting data from human personnel and manage to mix it up to provide the right XML files and telnet commands to the melted client (via MVCP protocol).

Then melted client reads XML make the composition for media+logo(s)+(optional overlays like lover thirds) and displays the content on the right "consumer".

The MLT projects supports a lot of consumers, also an ASI output card ... but in OTVA playout was made from a custom Ubuntu mini PC (sapphire Edge HD2) using hdmi output (video and audio).

Hdmi output was transcoded to SDI or plain analog PAL via adapters connected to DVB-T encoder/multiplexers ..... the remaining chain is known :D

This solution was (quite) painless and to switch from SD to HD you need only to change output resolution (by the way you can avoid to buy scalers 'cause scalind HD->SD or SD-> HD was made by software :D)
