放送波の MPEG2-TS に重畳されている EIT (Event Information Table: 番組情報) の生データを時系列でいい感じに表示するツールです。
@chinachu/node-aribts から取得した EIT の情報を、文字列や時刻を human-readable な形にフォーマットした上で、TOT (Time Offset Table: 時刻情報) と一緒に出力します。
Usage: EITViewer [options]
Options:
--input <path> 入力の TS ファイルのパス
--output-log <path> 出力するログファイルのパス (省略時は stdout に出力)
--eit-types <eit_types> 絞り込む EIT のタイプ (コンマ区切り、present/following/schedule から選択)
--service-ids <service_ids> 絞り込むサービス ID のリスト (コンマ区切り)
--event-ids <event_ids> 絞り込むイベント ID のリスト (コンマ区切り)
-h, --help display help for command--eit-types / --service-ids / --event-ids の3つのオプションを指定して、表示する EIT を絞り込めます。
以下は、EIT: EIT[present] & EIT[following] / service_id: 1032 (NHKEテレ1東京) / event_id: 24177,24185,24188,65522 の条件に一致する EIT を表示する場合のコマンド例です。
$ ./EITViewer --input /path/to/record.ts --output-log /path/to/log.txt --eit-types present,following --service-ids 1032 --event-ids 24177,24185,24188,65522Tips: TOT は基本5秒おきに送出されているため、EIT が送出された時刻は、(その EIT の直前の TOT の JST_Time に記載されている時刻) ～ (その EIT の直前の TOT の JST_Time に記載されている時刻 + 5 秒) の間になります。
たとえば、目当ての EIT の直前の TOT が2022-08-07T20:06:35+09:00なら、目当ての EIT は2022-08-07T20:06:35+09:00～2022-08-07T20:06:40+09:00の間に送出されたことになります。
