HDMI Mini vs HDMI Micro
HDMI Mini vs HDMI Micro
So what's the difference between the HDMI mini connector and HDMI micro connector? Let's look at some of the specs.
HDMI Mini Connector:
- Type C HDMI- 10.42 mm × 2.42 mm
- Defined in the HDMI 1.3 specification
- 19-pin configuration
HDMI Micro Connector:
- Type D HDMI- 6.4mm x 2.8 mm
- Defined in the HDMI 1.4 specification
- 19-pin configuration
As you can see, they both employ the 19-pin configuration, but the Mini HDMI (Type C) is different because all positive signals of the differential pairs are swapped with their corresponding shield, the DDC/CEC Ground is assigned to pin 13 instead of pin 17, the CEC is assigned to pin 14 instead of pin 13, and the reserved pin is 17 instead of pin 14. The Micro (Type D) uses the same pin configuration as the standard HDMI (Type A).
Mini HDMI (Type C) to Standard HDMI (Type A) cables are generally used for connecting your HD camcorder to your HDTV.
Micro HDMI (Type D) to Standard HDMI (Type A) cables are used for connecting smart phones like the Motorola Droid X and Sprint HTC Evo to HDTVs.

How to convert HD-SDI to HDMI?
Many HD broadcasting cameras are pushing out a HD-SDI signal that needs to be viewed using a HDMI connection on the other end. You'll need a HD-SDI to HDMI convertor, these converters are compliant with the Society of Motion Picture and Television Engineers (SMPTE) standard of 292M and 296M. These standards support data rates up to 1.485 Gb/s.
Everfocus model number EHA-SRX is capable of receiving HD-SDI digital video signal up to 1920x1080 resolution over 75ohm coax cable. This converter will provide a complete solution for the transmission and display of both interlaced and progressive scan HD-SDI digital video. Yes Everfocus is a security camera manufacture but don't worry, this will work for your broadcasting cameras too!
Let's get a look at it from our YouTube Channel
Features:
* Accepts HD-SDI digital video at 720p/60, 1080i/60 and 1080p/30 formats/frame rates
* Processes HD-SDI standard SMPTE 292M and 296M at 1.4585 Gb/s data rate
* Provides standard HDMI output for HD TV monitor display
* Integrated cable equalizer for long distance video transmission without loss of quality
* Capable of receiving HD-CCTV digital video over 75ohm coax cable at distanced over 100 Meters
* High quality digital video and audio transmission with zero latency
Now let's dig into the cable transmission. The EHA-SRX allows a total signal attenuation of up to 43.56 dB along the cable between devices. The actual maximum cable length depends on the attenuation characteristic of the particular cable being used. So if you have a long coax run make sure you have a kick ass quality cable so you have a lower signal attenuation.

How to Test an HDMI Cable?
Recently we had a contractor customer ask us, "What do you have for testing HDMI cables?" I then asked if he was making his own and if so I have a tester in mind but he had a couple of concerns. The first was that the end user provided the cable and wanted to make sure the cable worked properly since if there was a problem the customer may point the finger to him and not the cable. Second being that the cable was going to be pulled through a conduit and he wanted to make sure that the connectors were not damaged during the pull.
We recommended the Greenlee Data Shark HDMI Cable Tester.
The Greenlee DataShark HDMI cable tester can test for proper continuity before installation. Also a great diagnostic tool for checking cables already installed. The 1 piece design splits into 2 pieces a transmitter and receiver. The 9 LED readout is easy and very fast to read.
The contractor checked it out and for the price it was well worth putting another tester into his collection.
