Seems that no errors occured on the HD-SDI Links. It's a digital transmision that is monitored for transmission errors. If too many sum up there, you should be concerned. Since they are zero, everything is okay. This is just a status message.

It was notably important on the Series-1 projectors. It seems that TI had the SMPTE A and B lines a bit close on the PCB and they could "chatter." This would drive the SMPTE errors up. The "solution" was to use 50-foot SDI cables to attenuate the signal such that it was within the inputs AGC range but would not cause the chatter issue.

If you are seeing pixelation and such, it is a good idea to check the SMPTE error counts to see if they are going up...if so, check your HDSDI lines.
