      [PATCH] v4l: experimental Sliced VBI API support · 9db45506
      Mauro Carvalho Chehab 提交于
      Adds all defines, ioctls and structs needed for the sliced VBI API
      
      VBI = Vertical Blank Interval.
      
      It is related with the way TV signals work.  It sends a line, then, it has a
      retrace time to allow the tube to move electrons to the beginning of the next
      line.  This was the main reason at the beginning of analog B&W TV.
      
      There is a lot of bandwidth lost on VBI.  So, lots of TV systems use it to
      send other information such as Closed Captions and Teletext.  Also,
      broadcasters uses this as a channel to exchange information from the content
      producer to their subsidiaries at each city.
      
      There's already a raw VBI interface on V4L2 api, used for Closed Captions and
      Teletext.  The decoding is doing at userlevel space and it is mostly for
      analog TV signals, non encoded.
      
      Encoded signals (MPEG, for example), may need also to transmit other
      information (like, for example, display aspect, i.e.  4x3, widescreen...).
      Sliced VBI interface is a method to allow the video stream to transmit this
      kind of information.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
