HDMI, 10 & 14 pin camera connections
The HDMI Type A connector (13.9 mm × 4.45 mm male) is the most widely used, present on most TVs, recorders, and set top boxes.
The Mini-HDMI (Type C) connector (10.42 mm × 2.42 mm) is found on camcorders and DSLRs. The Type C pinout is similar to Type A but with positive signals swapped with their corresponding shield.
The Micro-HDMI (Type D) is intended for smartphones and similar small devices. It keeps the same 19 pins but in a much smaller package.
For historical reference, the 10-pin and 14-pin connectors from older video cameras are also included below (based on NATIONAL WVP-50N and SONY HVC3000C service manuals — pin-outs may vary by brand).
