It transmits only compressed and possibly encrypted MPEG data over the PCI bus, so you need an external software decoder and a decrypter to watch TV on your computer.

(http://www.friio.com/) The device has a GL861 chip and a Comtech JDVBT90502 canned tuner module. This driver ignores all the frontend_parameters except frequency, as ISDB-T shares the same parameter configuration across the country and thus the device can work like an intelligent one. As this device does not include a CAM nor hardware descrambling feature, the driver passes through scrambled TS streams. There is Friio Black, a variant for ISDB-S, which shares the same USB Vendor/Product ID with White, but it is not supported in this driver. They should be identified in the initialization sequence, but this feature is not tested.

From: Dmitri Belimov Hi All. When fast push-pull button of remote control we can received incorrect key code 0x00. Key information from IR decoder has ID of remote control 2 bytes, byte of key code and byte of mirror key code. Correct data 0x86 0x6B 0x00 0xFF Wrong data 0x86 0x6B 0x00 0x00 This patch added additional test of mirror byte for filtering. With my best regards, Dmitry. Signed-off-by: Beholder Intl. Ltd.

(happens for example at 687.25 Mhz) - On a lower frequency (511.25 Mhz) the picture is always sharp, but lacks colour. - No sound problems. - radio untested. Digital: - DVB-T/H stream reception works. - Would expect to see some more channels in the higher frequency region. Overall is the impression that sensitivity still needs improvement both in analog and digital modes.
