Tackling some FAQs relating to HDMI cables

The use of HDMI cables has increased with the times. The reason for this is attributed to the advent of modern technology like Blu-ray players and high definition TV sets. High definition multimedia interface (HDMI) cables are commonly used to transmit data of the highest quality from an external hard disk drive to your TV set.

Mentioned below are some frequently asked questions pertaining to HDMI cables.

What is the difference between HDMI v1.3, v1.3a and v1.3b?

As an end user, you might not notice any difference between v1.3, v1.3a and v1.3b. It is because there are no visible hardware changes or modification between the three versions. The minor adjustments made in the three versions are in no way related to the functionality.

Is closed captioning supported by HDMI cables?

With the advent of set top boxes, the responsibility of decoding the closed captioning was taken away from the TV sets and put onto set top boxes. While it was fairly easy to enable CCs on analogue TV sets, it has become a bit more complex on digital TVs. The process of decoding the CC with the help of HDMI cables depends on the version as well as your TV set.

What is the difference between a standard and an HDMI cable?

HDMI cables were divided into standard and high speed cables. Standard cables usually perform at a speed of up to 75-80 MHz and can support resolutions of up to 720p/1080i. On the other hand, high speed cables perform at speeds in excess of 400 MHz and are known to support resolution of up to 2560 x 1600 on WQXGA cinema monitors.
