Trouble with DVB-T2 on frontend 1
by Marko Mäkelä 03 Jan '22

03 Jan '22

Hi all, I recently got a USB adapter "Astrometa DVB-T2" that I would like to use with VDR. It comprises two frontends: /dev/dvb/adapter0/frontend0: Realtek RTL2832 (DVB-T) /dev/dvb/adapter0/frontend1: Panasonic MN88473 (DVB-T2 and DVB-C) I guess it is similar to this one; just a slightly different plastic case with some more ventilation holes: http://blog.palosaari.fi/2014/09/naked-hardware-18-astrometa-amdvb-t2-v2.ht… The hardware appears to work fine, once I copied the /lib/firmware/dvb-demod-mn88473-01.fw from somewhere. The firmware upload has failed at least once on the Raspberry Pi 2 (using Linux 4.9.59), but never on another machine that runs a 4.13.0 kernel. I did not yet get the infrared remote control to produce anything in evtest. With dvbv5-zap (after running dvbv5-scan), I can tune into DVB-T2 channels like this: dvbv5-zap -a 0 -f 1 -c dvb_channel.conf 'Yle TV1 HD' -r After this, I can play the video and audio stream on the Raspberry Pi 2: omxplayer /dev/dvb/adapter0/dvr0 Unless I explicitly specify the options -a 0 -f 1, then dvbv5-zap will fail to find any DVB-T2 senders, because it apparently defaults to frontend0, which is DVB-T only. In VDR 2.3.8, I have only been able to view DVB-T from the first frontend. When I did a trick and renamed /dev/dvb/adapter0/frontend1 to frontend0 before starting VDR, VDR no longer complained that the DVB-T2 channels (which I converted from the dvb_channel.conf to channels.conf with dvb-format-convert) not being available, but it did not seem to receive anything from these channels either. Also, after using dvbv5-scan or dvbv5-zap, I sometimes have to invoke w_scan to "reset" the hardware so that VDR can receive DVB-T channels. I would like to receive and record DVB-T and DVB-T2 on this setup. I am willing to try patches or do some programming myself, but I would appreciate some hints to get started. Marko

French DVB-T Channel IDs vs. EIT Channel IDs
by Patrick Boettcher 25 Jan '20

25 Jan '20

Hi list, since some time (1-2 years) I noticed that the DVB-T channels do not show EPG anymore. I'm not sure what is the root-cause: either it was the migration of French DVB-T to HD (in 2016) or an update of VDR. Anyway, this morning I took the time to figure out what is wrong and here is what I found. In short, the channel-ID generated from the one received in the EIT does not correspond to a known channel-ID from the channel list, and VDR drops the whole section: In cEIT::cEIT (from eit.c) we see tChannelID channelID(Source, getOriginalNetworkId(), getTransportStreamId(), getServiceId()); cChannel *Channel = Channels->GetByChannelID(channelID, true); and channel is NULL in my case. I added some debug prints to GetByChannelID() in the search loop: printf("sid: %d == %d, %s, %s %d\n", Channel->Sid(), sid, (const char *)ChannelID.ToString(), (const char *)Channel->GetChannelID().ToString(), Channel->GetChannelID() == ChannelID); And here is an example of what I get: sid: 517 == 517, T-8442-2-517, T-0-506-517 0 The internal channel ID of vdr reads T-0-506-517. 517 is the SID, 506 is the radio-channel frequency in MHz. This is the right internal channel for this EIT-section. The EIT-channel-ID is telling me that 8442 is the original network ID and 2 might be the radio-channel ID. I tweaked the operator==() of ChannelID to make it work, but not in a contributable manner. How should this be fixed correctly? Is this a regression introduced somewhere? Can it be solved by configuration? Thanks for any help. best regards, -- Patrick.

VDR ISDB-T support
by Christian Rodriguez 14 Sep '18

14 Sep '18

Hello everyone! I'm from Argentina, and up to last month I've been using VDR 1.7.262 with an ISDB-T USB adapter. It works really good, but the last week I've been trying to upgrade to VDR 2.2 and I've found a problem with ISDB-T cards: they are not supported. As I'm really interested in using VDR, I was digging inside the code and found a partial solution for this problem: as ISDBT is the same as DVBT, I've changed the way delivery system is queried. My changes are applied in a cloned repo at github: https://github.com/chrodriguez/vdr/commit/dadbca57c2dc55c1c53b4fa8f68b56728… That's the only change I've made. Now I can enjoy my fresh upgraded VDR installation!! I think a better refactor should be made, but for now it's working perfectly deployed as a docker container: https://registry.hub.docker.com/u/chrodriguez/vdr Thanks for this wonderfull project! -- Lic. Christian A. Rodriguez @car_unlp

ICAT-EGVE 2018 Call For Papers
by ICAT-EGVE 2018 07 May '18

07 May '18

*ICAT-EGVE 2018 Call For Papers* The ICAT-EGVE 2018 conference will be held November 7th – 9th in Limassol, Cyprus. This is the merger of the 28th International Conference on Artificial Reality and Telexistence (ICAT 2018) and the 23rd Eurographics Symposium on Virtual Environments (EGVE 2018). Together these are two of the oldest international conferences in the world on Artificial Reality and Virtual Environments, and provide a unique opportunity for researchers, developers, and users to share their experience and knowledge of Virtual Reality, Augmented Reality, Mixed Reality and 3D User Interfaces. This is a great opportunity to renew old friendships, make new ones, and experience all that Cyprus has to offer. Limassol, a city counting centuries of history, is located between two of the most renowned ancient kingdoms of the island, Amathus at the east and Kourion at the west. "Lemessos" as it is called by locals, is one of the fastest growing modern metropolises in Europe, with the most distinct project being the Limassol Marina. The beautiful coastline now covers a 15 kilometers distance, lined with hotels and beach bars and cafes, interspersed with eucalyptus groves and linked by a promenade popular with walkers and joggers. For more information see here <http://icat-egve2018.rise.org.cy/about-limassol/>. ICAT-EGVE 2018 is organized by the newly established RISE Research Center. The Research center on Interactive media, Smart systems and Emerging technologies (RISE) aims to become a Center of Excellence and a hub across the three continents bordering Cyprus, facilitating thus the local scientific, technological, and economic growth of the region. More information about the RISE Research Center can be found here <http://www.rise.org.cy/>. ICAT-EGVE 2018 seeks original, high-quality papers describing research, applications or systems in all areas of Virtual Reality, Augmented Reality, Mixed Reality, Telexistence, and 3D User Interfaces. Research papers should describe results that contribute to advancements in the following areas: - 3D interaction for VR/AR - VR/AR systems and toolkits - User studies and evaluation for VR/AR/MR - Telexistence, Telepresence and Tele-immersion - Haptics, audio, and other non-visual modalities - Serious games and edutainment using VR/AR/MR - Presence, cognition, and embodiment in VR/AR/MR - Novel devices (both input and output) for VR, AR, MR, and haptics - Multi-user and distributed VR, AR, tele-immersion and telepresence - Immersive projection technologies and other advanced display technologies Submissions in other related areas are welcome too. All accepted papers will be published in the Digital Library of the Eurographics. *Submission* Full papers must be in English and not exceed eight (8) pages in length. Short papers must be in English and not exceed four (4) pages in length. Both full and short papers should be formatted using the Eurographics format <https://www.eg.org/wp/guidelines/>.

Modified VDR User Counter
by Klaus Schmidinger 03 May '18

03 May '18

In an effort to avoid possible problems with the new data protection law in Germany ("DSGVO"), I have modified the VDR User Counter in such a way that it no longer asks for or displays the user's name, public email address and homepage URL. Any such previously entered data has been deleted from the database. Consequently, the page "People who have built a VDR" has been removed entirely, because it connected user names to VDR User Numbers. The VDR User Counter can be found at http://tvdr.de/counter.htm. Maybe this is a good time to refresh your entry in case it has a status of "outdated" or "unreachable" ;-). To do so, select "Edit your entry" from the counter's main page, enter your user number and password and click on "Edit my entry". Klaus
