自宅録画サーバーでNHK BSプレミアムとBSジャパンが録画できなくなったので，それの対応．

いろいろ調べていると，4K放送についていろいろ調べることになった．

０．はじめに

4K放送の闇？については，関連記事「」にまとめました．

１．環境

サーバー

Ubuntu Server 16.04.2 LTS

録画環境

Chinachu γ + Mirakurun + recpt1

（2017/02/16 くらいにインストールしてから未アップデート）

２．症状

録画データをみていたら，ファイルサイズが0なものが散見された．

すべてBSだったため，手動で録画してみると，ダブル録画させたときに高確率で同じ症状が出た．

チューナーがぶっ壊れたのかとおもい，知人からPT3をかりて換装後，再度テストしてみると，やはり録れない．

そしていろいろ悩んでいると，SプレミアムとBSジャパンのみが録れないことに気づいた．

（つまり，ダブル録画は関係なかった．）

そんなこんなでggっていると，このような記事をみつけた．

突然、BSジャパンの「日経プラス10」がChinachuで録画できなくなった。

調べたら、BSジャパンのチャンネルが2018年4月16日6時に

BS03_1　⇨　BS01_2

に変更になっていた。

あ，，，BS右旋帯域再編って，今年の１月に完了したとばかり思っていた...．

まだ続いてたんですね...．

３．対応

BS右旋帯域再編などについては「」でまとめるとして，ここでは対処だけまとめる．

/usr/local/etc/mirakurun/channels.ymlで定義されているチャンネル設定を編集するだけ．

■ 変更前

...
- name: NHK BSプレミアム
  type: BS
  channel: BS15_1
  serviceId: 103

- name: NHK BSプレミアム (サブ)
  type: BS
  channel: BS15_1
  serviceId: 104

...

- name: BSジャパン
  type: BS
  channel: BS03_1
  serviceId: 171
...

■ 変更後

...
- name: NHK BSプレミアム
  type: BS
  channel: BS03_1
  serviceId: 103

- name: NHK BSプレミアム (サブ)
  type: BS
  channel: BS03_1
  serviceId: 104

...

- name: BSジャパン
  type: BS
  channel: BS01_2
  serviceId: 171
...

４．残った不具合

無事，NHK BSプレミアムは録画できるようになったが，BSジャパンがなぜか録れない．

下のコマンド結果をみると，どうやらBSジャパンではserviceIdが取得できていない．

さらにBSプレミアムのなかにBSジャパンがあったりして，よくわからない．

まあ，NHK BSプレミアムは見えるようになったので，ひとまず様子見ますか．
