  • Page 27: Appendix D: Hdmi Handshaking

    Stan Bleszynski, Bryston Ltd . HDMI Handshaking When SP3 selects HDMI input port as its audio signal source, it acts as an HDMI repeater, placed in between HDMI signal source (DVD player, BD player etc) and HDMI signal “sink” (TV screen, TV projector etc). Every class of the devices on the HDMI chain has to respond to the HDMI handshake procedure, initiated by the signal source, that is by a player.
  • Page 28 The signal source determines the channel format. If the number of channels being played is not as expected, for example 2 instead of 5.1 or 7.1 then the SP3 and the player may have to re-handshake the communication protocol through HDMI in order to reset the proper status.
