A connected home: More than just cables

. Kamis, 17 Desember 2009

ASmall as it is, there are seven telephone sets in my house, including a cordless one that seems to disappear into a vortex all the time.

Radio Shack intercom is also installed, connecting our bedroom and my study. All of them work. The few places that do not have a telephone set are the kitchen and the bathrooms.

My low-cost AKAI stereo amplifier is also connected to two pairs of large speakers. One pair is inside my study, which has become the command center. Another pair lives in the living room. There is a LinkSys router with wireless access point just outside my study. My daughter’s PC is connected via a long UTP cable to the router, which in turn is connected to CBN DirectNet Wireless modem.

There are three TV sets in the house, although only one is connected to a First Media decoder. You know, the cable TV provider wants us to pay extra for each additional decoder, and I have refused to spend more for a decoder that I would hardly use. Now, is my house connected?

Hardly, as a connected home has to do more with content rather than cables. Do I have the ability to remotely pick up the content stored in the hard disk of my media center at home with my mobile device? Maybe. But, can I push the content I am creating to the computer in my study in a safe manner? That would be harder to do. What about if you are abroad and want to send the video you made with your smart phone into the TV in your living room? You will most likely need to wait until you are back and have the opportunity to burn the video onto a blank DVD and then play it on the DVD player hooked to that TV.

A connected home, which combines telecommunication and consumer electronics, hinges on a broadband pipe. A few years ago, we talked about Triple Play, which consisted of two bandwidth-demanding services in the home — Internet access and TV — and the telephone. When wireless was added, we had quadruple play.

The aim is to make life more enjoyable (for those who can afford it, of course). The backbone is a home network, and it can be both wired and wireless, and it may also include control systems to manage IP appliances such as the air conditioners and the water heater.

How serious is the concept of the connected home experience today? Well, here is a new abbreviation that you will encounter more frequently: Digital Living Network Alliance, or DLNA. It is based on the so-called Universal Plug and Play (UPnP), which is the standard that home appliances and devices will likely to follow in the future in order to give us the connected home experience. So, the objective of the DLNA can be summed up as full compatibility among consumer equipments. It will enable us to pull or push content remotely to our devices, too.

DLNA claims that currently 240 companies have joined it, including makers of consumer electronics, computers and mobile device. “DLNA also includes many component and software developers”, they write on their homepage.

What the organization does is give certification, of course. So, if you buy a high-end home appliance today, keep an eye out for the DLNA logo. Incidentally, in the near future I will be reviewing a gargantuan LED TV from Samsung, which is already DLNA certified.

In making the connected home a reality, a piece of software is needed. Ericsson, the Swedish telecom giant that we usually recognize for their infrastructure technology, has developed what it calls a “Connected Home Gateway”. Ericsson Multimedia Business launched it during the Mobile World Congress in Barcelona last February.

The Connected Home Gateway provides security for the connectivity between home and telecommunication networks. According to an Ericsson press release, it also provides a single point of entry for IPTV and communication services. It is also DLNA compliant. In fact, another Ericsson press release I received last month announced that their Connected Home Gateway software had received the 2009 TelcoTV Vision Awards.

In simple language, the DLNA is another industry buzzword that you will see more and more. You need to ensure the compliance of the products you are buying — if you’re thinking about building a connected home.
