From ANSI-CTA-608-E R-2014 section 8.4: > When closed captioning is used on line 21, field 2, it shall conform > to all of the applicable specifications and recommended practices as > defined for field 1 services with the following differences: > 1. The non-printing character of the miscellaneous control-character > pairs that fall in the range of 0x14, 0x20 to 0x14, 0x2F in field 1, > shall be replaced with 0x15, 0x20 to 0x15, 0x2F when used in field > 2. > 2. The non-printing character of the miscellaneous control-character > pairs that fall in the range of 0x1C, 0x20 to 0x1C, 0x2F in field > 1, shall be replaced with 0x1D, 0x20 to 0x1D, 0x2F when used in > field 2. This basically means that `cc1=0x15` in field 2 should be interpreted as `cc1=0x14` in field 1, and same for `0x1D -> 0x1C`. The `isMiscCode` method above already handles this by ignoring the LSB (the only difference between `0x14` and `0x15`, and `0x1C` and `0x1D`) by AND-ing with `0xF6` instead of `0xF7`. This change uses the same trick in `isServiceSwitchCommand`. Issue: google/ExoPlayer#10666 #minor-release PiperOrigin-RevId: 483927506 (cherry picked from commit 7c6d492ff19b6aead4cc6f1f9a426145fc1faa0d)
