While HDMI cables are very popular these days for connecting high definition devices, they come in multiple types. At the same time there is much hype as well as misconceptions about the pricing of these cables in the market among the end users. It will not be prudent buying the cheapest version of the HDMI cable that would go out of order after a few days. Rather it would be good buying something in the range of £2-£20 that would be much better option for the buyer.
However, deciding on the type and price can only be possible once the buyer comes across the information on the types of HDMI cables available.
We start with HDMI over IP.
- A connector for 1080p video and 5.1 audio, the HDMI over IP project offer numerous functions that can result in inspirational audio and video output for the user.
- It not only works on the TV but also on LAN and WAN network and Internet.
- The point to point connector allows sending of HDMI 1.3 signals to multiple LCD panels and to one or more of the HDMI video projectors. The source will return an IR control signal using cat 5, 6, or 7 over the standard Ethernet infrastructure.
- It can cover approximately hundred or more remote displays with the Ethernet switches designed for the three levels.
- HDMI over IP is a high speed connection, very reliable, and durable, and the quality of the picture and sound are excellent.
- Each unit is installed with shielded twisted pair STP or UTP cable for each of the devices.
Another format is the HDMI over cat or high definition multimedia interface category is unusual in multiple senses. Data transfer is very high at 1080p with the capacity of 48 bits. It allows the user more control as it has the ability of capturing data from the remote sites. The process is also very helpful in controlling signals and elimination of disturbing sounds emanating from remote locations. With HDMI over cat, the HDMI itself can be enlarged.
HDMI cables are basically meant for connection of multiple digital devices and both source and destination points should be digital as always. Broadly speaking one can classify the HDMI cables in to four categories.
- Category A cable as 19 pins and male connectors with dimensions of 13.9mm x 4.45mm and the female socket with 14mm x 55 mm and has the bandwidth required supporting the HDTV type of devices. It is also the most widely used HDMI connector cables.
- Category B is a bit larger where the male connector has the dimensions of 21.2mm x 4.45mm as well as 29 pins. It can carry and transmit double the video capacity of type A. It is also designed for future displays such as the WQUXGA.
- Type C is designed to be used in small portable devices that do not have space for sockets and the connector dimension is only 10.4mm x 2.42mm. However, it still has 19 pins. It can also be interconnected with type connectors.
- Finally; the type D connectors are similar to A and C but are still smaller and compressed into form like the min USB. The connector dimension is only 2.8mmx6.4mm.
All these cables are available in most mobile and HD device stores. However, it depends on the exact requirement of the user that will decide which of the four types he or she buys.
