There has been much debate and deliberation over the last ten years concerning the most advanced distribution infrastructure for in-home networking. An ever-increasing user demand to access entertainment media anywhere inside or outside a home has exacerbated concerns and fuelled friction among industry leaders.
Since 2005, a growing number of service providers, equipment manufacturers and content developers agree existing coaxial cabling installed within the average home or business is capable of supporting high-performance, high-capacity transport of HD media and interactive data. Coaxial cable has withstood the test of time and continues to be the most robust, dependable and available communication medium for in-home entertainment.
The introduction of the Multimedia over Coax Alliance (MoCA) home entertainment network standard has made it possible for the average person to enjoy the latest entertainment technology in TVs, DVRs, console games, network-stored photos and video and other advanced electronic devices. MoCA home networks enable on-demand access to entertainment media to and from any MoCA-compliant device within the home.
Although existing in-home coaxial networks are capable of great things, they do require the installation of upgraded MoCA-compliant components to efficiently distribute HD media and data throughout the home.
While the use of Wi-Fi and Ethernet have a place in a home data network, video transport across coaxial cable is more efficient than other seemingly easier alternatives. A MoCA-enabled home entertainment coaxial network is the preferred transport for entertainment media, but in order to ensure the best performance for their customers, installers should be aware of the practicalities involved.
The following are the top five challenges installers face when configuring a MoCA-compliant home entertainment network:
Daisy-chained coax network installation.
An installer must ensure each end-point connection (e.g. to a TV or set-top box) is through a dedicated, home-run coaxial cable.
Home-run coax network installation.
Coaxial home network for single-source content access.
Coaxial home network for equal content sharing.
Advancements in home electronics, content availability and personal infotainment devices will continue to drive the demand for the delivery of high-quality entertainment media. The development and continued advancement of MoCA components allow the average individual to utilise their existing home coaxial cabling to get what they want where they want it. However, it is important for installation and integration professionals to MoCA-tize existing coaxial networks in order to ensure optimal performance. These professionals need to identify potential network problems prior to implementation, so it advisable to conduct a site evaluation in advance, plan properly, and use high-quality, SCTE-compliant components.
While the above list may not solve your ever-growing need for continued education to keep up with evolving technologies, we hope that you can use some of these tips to help you on your next project.
No matter what new technologies are introduced, there will always be growing pains for manufacturers, consumers and professionals adopting these technologies. These growing pains enable companies like us to be the pain relievers for the integration professionals, providing the products to simplify the interface of the new with the old. One thing is for certain, there is never a dull day at the forefront of emerging technologies!
