Choices in Distributing High Definition (HDMI)

The general direction of the article is the available technologies, the standards that need to be applied to do installations and CUSTOMER SERVICE  4k iptv. This is a general guide and there are many other aspects to consider, but hopefully, it helps to show you where careful consideration needs to be when making the decision to distribute High Definition and for you to get the right HDMI system that will suit your needs completely.

HDMI cables are becoming one of the most common cables found in a household today. As HD is a fairly new technology in South Africa there have been some misunderstandings that occurred with the South African Consumers. Firstly, there are many different wire gauges and different internal compositions. Don’t worry about the compositions. Good quality copper cable will do the trick.

The important thing to remember is that an HDMI Cable does not cost R 1000. The South African consumer has been mislead into thinking that a R 1000 cable is better than a R 85 cable. This is not true, as the important thing to remember is longer HDMI cables should use thicker wire. I personally recommend and purchase gold platted 28 AWG HDMI cables.

Almost all Blu Ray and set top box manufacturers (DSTV HD PVR) include HDMI cables with the item and these are not suitable. These cables are of a lower grade and are fine for connecting directly to HD TVs if they are really short (less than 1 meter). I have had to replace many of them in the past.

The only issue is that when it comes to distributing the signals to remote locations connection issues do occur. So when purchasing a new Blu-ray just upgrade your HDMI cable, but don’t go overboard on what you pay for the HDMI Cable. Distributing HDMI signals with HDMI Cables to multiple locations, like bedrooms and patios, is an issue as the HDMI Connector is large and getting it though conduit is almost impossible. The second issue is that extending past a 10 meter length may cause performance issues due to signal attenuation. This is why there are so many different technologies offered to distribute to remote points.

Used to optimize the allocation/distribution of digital media from a centralized location in the public or private cloud networks to the end user, content delivery networks move contents closer to the end recipient on PCs, mobile phones, set top boxes or other digital devices and gaming consoles. They are aimed at moving content closer to the end recipient and hence making the networks performance better through increased efficiency and reduced latency or jitter.

Content delivery networks – CDNs apply a variety of technologies & architectural topologies to augment the performance, speed, dependability & efficiency through network delivered content as it makes the way from the content owner to the end consumer. The basic mechanism of CDNs include distributed storage, reproduction and an edge cashing capacity nearly placed to or within broadband service provider (also known as “eyeball” networks).

Content switching and load balancing are some of the CDN technology elements. Smart network layer routing and incorporated software directs content requests to the “optimal” edge server best positioned to serve up the content and ascertain the cleanness of the delivered contents. This process of clear content delivery can be implemented at varying positions in the content delivery supply chain with the involvement of different parties (providers of collocation services), producing opportunities for a variety of players in the CDN space.

The business model of CDN / collocation services providers is determined by the range of network resources and the customer relationship to their disposal. They could be unidirectional and hence serving only one portion of the digital content value chain as well as multifaceted by serving a huge variety of different ecosystem participants, including end-user. They can leverage their own upstream or downstream facilities on the basis of infrastructure or lease portions of the infrastructure from third party suppliers and hence function as virtual or overlay networks. The varying approaches to content delivery networks can be summarized as follows:
