From 5ae93fa2a3fc12c8d5e4c3f22917f4185b3feadd Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 23 Oct 2008 00:07:42 +0000 Subject: adding sharp s921 ISDB-T driver From: Markus Rechberger s921_module.c: wrapper for the dvb frontend interface s921_core.c: core s921 1seg ISDB-T driver, everything is set to auto as much as possible in order to not require certain parameters which currently cannot be passed to the ISDB-T chip. ISDB-T support can be tested using dvbscan, dvbstream/snoop and mplayer Tested 1seg H264/aac stream with this driver using a custom linux ISDB-T player Signed-off-by: Mauro Carvalho Chehab --- .../drivers/media/video/empia/sharp/s921_module.h | 49 ++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 linux/drivers/media/video/empia/sharp/s921_module.h (limited to 'linux/drivers/media/video/empia/sharp/s921_module.h') diff --git a/linux/drivers/media/video/empia/sharp/s921_module.h b/linux/drivers/media/video/empia/sharp/s921_module.h new file mode 100644 index 000000000..78660424b --- /dev/null +++ b/linux/drivers/media/video/empia/sharp/s921_module.h @@ -0,0 +1,49 @@ +/* + * Driver for DVB-T s921 demodulator + * + * Copyright (C) 2008 Markus Rechberger + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
