Date: Thu, 23 Nov 2017 10:24:46 +0200 [thread overview]
Message-ID: <1511425486-2318-2-git-send-email-olli.salonen@iki.fi> (raw)
In-Reply-To: <1511425486-2318-1-git-send-email-olli.salonen@iki.fi>
From: Olli Salonen <olli.salonen@iki.fi>
Xbox One Digital TV Tuner is a low-cost USB 2.0 multistandard TV tuner. It supports DVB-T, DVB-T2 and DVB-C broadcast standards.
USB bridge: DibCom 0700C
Demodulator: Panasonic MN88472
Tuner: TDA18250BHN
The demodulator requires firmware. Download one from here:
