Ubuntu 12.04 使用大通USB電視棒AD-525

在某家家都樂得辛福的大賣場出清，買了號稱支援Linux的平價USB數位電視棒AD-525，不過原廠光碟片裡附的driver只支援kernel 2.6.20 – 2.6.33, 如果是Ubuntu平台的話應該是到10.04。

要在Ubuntu 12.04上kernel 3.2.0下跑看來是要自力救濟，玩Linux自己來是在平常不過的事，先上網查這支USB DVB使用的晶片為IT9135，根據網站資料如下，應該有辦法在kernel 3.2上使用。

首先直接接上Ubuntu 12.04什麼動作都沒發生，試著load dvb_usb_it913x 和 it913x_fe看來也不會動，先在這裡卡了一陣子，隔天發現某站在寫了可以動的方法：

http://ubuntuforums.org/showthread.php?t=1898046

sudo apt-get git
mkdir v4l
cd v4l
git clone git://linuxtv.org/media_build.git
cd media_build/
sudo apt-get install libproc-processtable-perl
./build
sudo make install

然後再加firmware
cd ..
wget http://www.ite.com.tw/uploads/firmware/v3.6.0.0/dvb-usb-it9135.zip
unzip dvb-usb-it9135.zip
dd if=dvb-usb-it9135.fw ibs=1 skip=64 count=8128 of=dvb-usb-it9135-01.fw
dd if=dvb-usb-it9135.fw ibs=1 skip=12866 count=5817 of=dvb-usb-it9135-02.fw
sudo cp dvb-usb-it9135-0* /lib/firmware/
Reboot，然後跑一下檢查

dmesg |grep it913x
[ 9.662488] it913x: Chip Version=02 Chip Type=9135
[ 9.662971] it913x: Firmware Version 52887808

[ 10.689092] it913x: DEV registering device driver
[ 10.689119] usbcore: registered new interface driver it913x

這樣就完成的driver的部份，接下來準備播放軟體我用比較簡單好用的vlc播放程式
參考下列網址：
http://www.ubuntu-tw.org/modules/newbb/viewtopic.php?post_id=65236
sudo apt-get install dvb-apps
cd /usr/share/dvb/dvb-t/
vi tw-Taipei # modify content as below
T 533000000 6MHz 2/3 AUTO QAM16 8k 1/4 NONE

T 593000000 6MHz 2/3 AUTO QAM16 8k 1/4 NONE
scan /usr/share/doc/dvb/dvb-t/tw-Taipei > channels.conf
在中文的Ubuntu環境下scan出來的channels.conf的中文名稱頻道會是亂碼。

進入vlc 開啟 channels.conf , 播放清單內就有所有數位電視台(含HiHD)
也可以產生一個桌面圖示 ,指令為 vlc "你的PATH" channels.conf

我掃出來的channels.conf內容, 指令 vlc channels.conf就可以開始看無線數位電視了，開心呀。
