千円台ワンセグチューナーのDS-DT305BKを刺してみたかったので
RTL2832UのドライバーはカーネルVer3.0.0用(他のVerでも一部使える)のがgithubに公開されていますが
- ambrosa/DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0
- DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0
(上記とも3.8.13ではコンパイル通らない)
実はカーネル3.6以降でRTL2832のドライバーがカーネル本体に入ってるそうです。
実際探してみるとmenuconfigの
Device Drivers -> Multimedia support->Media USB Adapters->Support for various USB DVB devices v2->Realtek RTL28xxU DVB USB supportにありました
ちなみにGeneral setup->Prompt for development and/or incomplete code/drivers(開発中/不完全なコード/ドライバーを表示)は有効にしないと上のRTL2832の項目は出て来ません(そこで一時間くらいハマりました)
Realtek RTL28xxU DVB USB supportを有効にして再構築して再起動したら無事認識しました

/dev/dvb/adapter0/{demux0,dvr0,frontend0,net0}として出て来ました。
さてワンセグ見ようと思ってdvbstreamをインストールしてやってみましたが
“dvbstream -f <地デジの物理chの周波数(kHz)> 8192″とやれば標準出力にtsが出てくるはずですが・・・
$ dvbstream -f 515143 8192

となったまま何も起きないので^Cしました。
何でだ・・・・

パラメータがおかしいように感じます。日本のワンセグの場合は6MHz幅ですが、
エラーメッセージを見る限りでは英国のDVB-Tを受信するための設定になっているかと
他のワンセグの事が書いてあるページ見るとdvbstream -f 周波数 8192でできてるようですが、RTL2832Uは違うんですかね・・・
また時間がありましたら調べてみます。
