Hello everyone, For those interested in our ISDB-T transmitter project (see my previous mail to the list below), I wanted to share the news that we (finally) got it working with commercial TVs. So far, the transmission was correctly displayed by SDR-based receivers, but the behavior with "off-the-shelf" TVs was erratic (to be more blunt: it didn't work). This week we found out why and it's now working nicely. We are still testing it, and in particular we'll try to use it with cheap SDR transmitters (rpitx and osmo-fl2k).
As usual, it would be very interesting to receive feedback (both failures and successes). best Federico ------------------------------ *From*: Federico 'Larroca' La Rocca *Subject*: [Discuss-gnuradio] ISDB-T transmitter OOT *Date*: Fri, 21 Dec 2018 14:13:03 -0300 ------------------------------ Hi everyone, I'm very glad to announce that our OOT gr-isdbt now includes the transmitter and may be considered (almost) complete. The repository is at https://github.com/git-artes/gr-isdbt. For those of you who did not know it, we developed gr-isdbt some years ago now (I think 2015 was the year we considered it useful) and it was a receiver-only for ISDB-T (the TVD standard used mostly in south america and Japan). To give a little bit of context, last year two students of ours (Santiago Castro and Javier Hernández) here in the university started to work on the implementation of the transmitter. Their work is still available at their repo (https://github.com/jhernandezbaraibar/gr-isdbt-Tx), although it may be considered deprecated, since over the last few months I've integrated their work into gr-isdbt and significant changes were introduced in the process. For those interested in using it, please note that the transmitter is still WIP. In particular, I have tested it somewhat thoroughly in software and I am confident it works as it should (we have included a full transceiver example in the corresponding directory). I am now seriously testing it in over-the-air transmissions with not-so-satisfactory results. However, I'm leaving for some weeks for holidays, thus the announcement. Feedback is, as usual, more than welcome. best Federico
