This is my design for receiving HDMI input, then extracting the video data, the Video Inforframe and audio samples, then using that to display audio db meters on the top corner of the screen. Currently for simplicity the output is only DVID.
Supports HDMI formats: -720p@50
Colourspaces / formats:
Switch 0 will turn real-time edge detect off and on.
Switch 1 will turn guidelines off and on. Will only show in 1080p 1080i and 720p resolutions.
Sources tested with:
Sinks tested with:
Currently extracts only two channels of audio
Does not adjust PLL settings for input clock, so the PLL is run slightly out of spec.
Image may re-sync once after a few seconds if symbol errors are seen.
There are timings errors, as generating 148.5MHz HDMI using the Artix-7 chip is actually out of spec. Expect seven failing paths and about 20ns of negative slack.
