There is an alternate driver for the earthsoft pt1 card, honeyplanet's "pt1-drv". This pt1 driver is also more recently updated, with development as recent as five months ago; the v4l-dvb "earth-pt1" driver was last updated 20 months ago. Last time I checked, they work just as well for streaming video, but I don't know about other features (tuning, etc). All of the Japanese pages regarding PT-series cards reccommmened to blacklist the v4l-dvb driver and install the honeyplanet driver, but I do not know why as I can not read Japanese and what I gather from google translate is that no particular reason is given.

The honeyplanet repository includes one more, very important piece of code: a decryption program. The PT-series cards are actually useless by themselves, as they have no hardware to utilize a B-CAS card or decrypt the ISDB-T/S/C stream. This requires an external (usually USB) smart-card reader, a B-CAS card, and some program to decrypt the video stream. At honeyplanet, there is a branch, "b25", of pt1-drv containing such a program, "arib25". As far as I know it is the only (open-source, linux compatible) B-CAS decryption program in existence. It is interesting to note that this program does not have it's own repository and has not been merged into the main driver, as if it's development were terminated.

arib25 & pt1-drv install

I've written a guide for setting up the card using this driver in Ubuntu. This is working for me, currently in Ubuntu 12.04 with kernel 3.5.0-18-generic and 3.5.7 (a custom kernel). Earthsoft PT2 This guide should work for PT1 as well, and may be similar for PT3 although it needs a different driver (PCIe). Eventually I'll get around to merging this guide with what's here if no one beats me to it. Quequotion 20:18, 17 December 2012 (CET)
