HDCP overview

.... (Aaron or Rob) 

HDCP Compliance

Any HDCP-protected signal must remain HDCP-protected through the entire HDMI chain. This applies to all BrightSign players with HDMI inputs (the XD1230, XD1132, 4K1142, XT1143, and XT1144). If the HDMI input signal is protected by HDCP:

  • BrightSign players cannot encode the HDMI input for streaming or saving to file.
  • BrightSign players cannot display the HDMI input if any device in the HDMI chain is not HDCP-compliant or refuses a HDCP-protected handshake/connection. This includes HDMI splitters/DAs, media converters/transceivers (HDMI-over-Cat5, etc), A/V receivers, TVs/displays, analog output (on XD1230 and XD1132), and display encoding (stream the player output screen). In this case, BrightSign players will still play the audio (barring bugs or incompatibility) from the HDMI input, but the area where the HDMI input video should be will be empty/gray.
  • For more details on how streaming and HDCP work in the BrightSign system, see HDCP.

Additional notes

  • The player only enables HDCP on the HDMI output if HDCP is detected on the HDMI input, save for Aaron's comment above?????
  • Set top cable, satellite boxes, and streaming devices enable HDCP on their output for obvious reasons.
  • Most game consoles enable HDCP on their HDMI output, though in some cases it depends on the output mode or software being used.
  • Some MacBooks will enable HDCP on the output if the destination device reports it supports HDCP, regardless of whether protected content is being displayed or not. 
  • Some computer DVI graphics cards can support HDCP over DVI, as can some DVI AV devices like certain projectors and DVD players with DVI output, however, most DVI-HDMI conversion will lose HDCP and a lot of early displays don't support HDCP over DVI.
  • Some early HDMI displays don't support HDCP over HDMI either. If it's not specifically mentioned, it probably isn't supported on the device.
  • There was an allowance in the DMCA for a HDCP-protected source device to allow SD (Standard Definition) analog output, but in practice this was rarely seen/used.
  • There are some instances where an HDCP-protected source can end up being output via analog on devices with both HDMI and analog outputs, but these should not be relied upon. This doesn't apply to current models without analog outputs.
  • HDCP 1.x and HDCP 2.x (available in HDMI 2.x) are separate entities. While HDMI 2.x devices are generally supposed to fall back to work with HDCP 1.x devices, it isn't always a smooth process, hence devices like HDfury Integral and similar in-line conversion/translation devices.
