Bring back Firefly

[ikarus23]

I know the readme says it won't. But please reconsider this! I really need this feature! I totally trust in in your coding skills! You can do it! And if not, maybe someone in the community is able to issue a pull request to resolve this?!

[fsphil]

Only versions 1.01 to 1.14 are supported. Waiting on further updates from upstream who have been unresponsive after the project was forked.

can anyone please tell me what Bring back Firefly is? (the onylthing I was able to find was a television show: http://io9.gizmodo.com/theres-still-a-way-firefly-could-come-back-to-televisi-1521723457 )

Thanks for Anwsering PS: do you think you could compile hacktv for windows (since libhackrf exist for windows and GNURadio works on windows nicly too: https://github.com/pothosware/PothosSDR/wiki/GNURadio)

PPS: you think you could add Teletext in the future: https://github.com/ali1234/raspi-teletext (Teletext modulator) https://github.com/peterkvt80/vbit-pi (Teletext Generator in C) https://github.com/peterkvt80/vbit2 (newer Teletext Generator in C++)

Thanks for Anwsering and Best Regards

Firefly is a long term goal :-)

I don't have Windows here but I don't see why it's not possible. hacktv does not use gnuradio, but it will need libhackrf and ffmpeg to compile.

Teletext will probably happen at some point, yes.

Thanks so what is Firefly? (Is this analog-tv encryption method like Nagravision and Videocrypt (will those be added at some point?)

Thanks for Anwsering and Best Regards

[fsphil]

Yes it's the TV show :) Although I am now tempted to make an encryption system named Firefly.

I have just added Videocrypt support, see commit 276d76521cb8f2a2f20b9417767cf5b6cb7d1aa0. I'm currently researching Nagravision.

[veso266]

yea Thanks now I just need to find a Videocrypt Descrambler (is there any software descrambler?)(can PAL L television handle it?)

you think you could add Zweikanaltone (A2 Stereo): https://en.wikipedia.org/wiki/Zweikanalton PS: do you think you could add clock and date and name of the station to Philips PM5544 Test Card? (something like this: https://www.youtube.com/watch?v=KUenRyt5u5Y)

Thanks for Anwsering and Best Regards PS: if you need it there is also python implementation for NTSC: https://github.com/argilo/sdr-examples/blob/master/ntsc/ntsc-encode.py

[fsphil]

It can already transmit NTSC. PAL-L video is identical to PAL-I, it would be trivial to add.

You need to open separate issues for these :)

[veso266]

OK Openned separate issue for zweikanaltone and Test Card: https://github.com/fsphil/hacktv/issues/3

Any update on this please?

Hi there, sorry for late replay (don't have much time for playing right now :smile: )

after compiling the new version (had to change theese 2 in mac.c (line 451)

	/* Get the timezone offset */
	#ifdef __MINGW32__
		localtime_s(&timestamp, &tm);
		i = tm.tm_mon / 1800;
	#else
		localtime_r(&timestamp, &tm);
		i = tm.tm_gmtoff / 1800;
	#endif
	if(i < 0) i = -i | (1 << 5);
	
	/* Calculate Modified Julian Date */
	#ifdef __MINGW32__
		gmtime_s(&timestamp, &tm);
	#else
		gmtime_r(&timestamp, &tm);
	#endif

I tried it on PAL-L (for some reason I had to set picture to SECAM not PAL, but sound could be in PAL-L)

the colors were a bit wierd (but it could only be my television set that does wierd things https://youtu.be/2jO025ZIPKc

sorry for the audio (some morons decided that the music that was playing is copyrighted (even they have no idea what I am doing :smile:)

[fsphil]

hacktv's l mode is always secam. If you want to add a pal-l mode you'll need to edit video.c.

Please open a new issue for these types of requests, unless it's related to the TV show Firefly :-)
