HDMI (High Definition Multimedia Interface) Cable and Its Functions

HDMI (High Definition Multimedia Interface), is currently one of the advanced features embedded in various electronic devices, which require an HDMI cable to enjoy clear sound and picture.

Usually, ordinary people think of HDMI as a USB port and are often confused when the Flashdisk can’t be connected. Sometimes they take their laptops back to the shop where they were purchased, their excuse being a product error. This is one example that does not understand the development of multimedia technology today, because there is no basic understanding that explains the function of HDMI in your device.

Just like most electronics sales girls who sometimes incorrectly indicate ‘which is the USB port and HDMI port’, even though they are salespeople who spearhead product sales. But, we’re not talking about products and sales, this is just an introduction to HDMI ports and cables.

High Definition Multimedia Interface (HDMI)

Several leading electronics manufacturers such as Sony, Philips, Panasonic, and domestic electronics manufacturers are now also providing HDMI ports on their products. This HDMI license has been held by about 1200 electronics companies that use this feature as their standard multimedia port.

And we know that HDMI technology delivers crystal clear picture and sound quality with HD technology supporting eight channels (192 kHz) of compressed digital audio. HDMI provides the best picture quality because it doesn’t require lossy analog for digital compression like the S-Video type. From this it is clear that the technology carried by HDMI is much sharper in producing images up to 1080p resolution, able to minimize excess light compared to analog systems.

Even better, HDMI supports two-way communication between the video output source and the DTV, enabling automatic one-touch play configuration. Gadgets usually provide the most effective format according to the quality and electronic support, ranging from 480p and 720p.

Choose the HDMI Cable Type As Needed

Well, why do I suggest not to make a mistake in buying, either buying a gadget or a connecting HDMI cable. You should also know that HDMI cables have different heads (cables recognize the term Male/Female). The HDMI cable used from the laptop usually uses the Full Size Type, while from the videocam uses the Mini Type or Micro Type HDMI cable, and video output to the LCD/LED TV screen more often uses a Full Size HDMI cable.

HDMI Cable Full Type

In other words, from the laptop to the screen both use a Full Type HDMI cable. And from the videocam to the screen using a Mini/Full HDMI cable. So, there are three types of HDMI cables being traded and you shouldn’t buy the wrong one, because HDMI cables are more expensive than regular S-Video cables.

There are three versions of HDMI that have been produced in several electronic devices, including HDMI 1.1 which supports DVD Audio, HDMI 1.2 supports the One Bit Audio (Direct Streaming Digital) format, and the last one is HDMI 1.3 which supports Higher Speed ​​HDMI with data transfer rates of 10.2 Gbps and high resolution. HDMI 1.3 currently supports Doulby, DTS, TrueHD, and DTS-HD audio formats.

To enjoy 1080p content (Blu-ray Disc) or advanced video technology (3D, 4K, Deep Color, Refresh rate 120Hz) it is recommended to use a High Speed ​​HDMI cable. And for 1080i or 720p (usually used on broadcast and satellite HD signals) it is recommended to use a Standard HDMI cable (HDMI 1.1 or 1.2)

In home theater mode as in a separate room, HDMI cable components can be placed relatively far from each other. Cable length is usually 25 to 100 meters with a note, if you want 1080p quality using a cable more than 25 meters, you must provide an amplifier where the circuit is embedded with a separate connector that requires an external power source.
