IPTV - 10 Important Facts

Is IPTV technology everything it's supposed to be, or is it just another example of technological hype? Here are 10 all-important facts and advantages relating to IPTV. Maybe this information can assist your decision as to whether you are ready for the IPTV revolution.

1. Internet protocol television or IPTV, is a progressively popular technology for the transportation of data information and Audio and Video (AV), across an IP based digital network. This might include Ethernet, WAN, LAN or the internet. Add to the equation a set top box (STB) and AV information can be streamed over existing networks to PCs or televisions. It's also possible for IPTV to be one to one (Unicast) or one to many (Multicast).

2. According to new research findings, currently 15.5 million people subscribe to IPTV services, 8.4 million of these subscribers are from Europe.

3. Because of the high bandwidth demands of digital video, IPTV requires broadband Internet connectivity. Theoretically, plugging in to this high speed internet would allow IPTV users additional control over their television programming and the ability to tailor-make it to their personal preferences.

4. Crucially IPTV systems avoid interruption of critical networks by employing a separate video LAN (local area network).

5. All free-view channels are delivered without SAT or Terrestrial receivers.

6. It has been predicted that compared to the current 3.3 million subscribers in the USA, there will be approximately 12.7 million IPTV users by 2012.

7. Local content, movies and sport may be added for supplementary income in hotels, or provided without charge to a student campus.

8. AV sources can be streamed over present networks to PCs or televisions with the addition of set top boxes (STB).

9. All TV programmes can later be retrieved from the IPTV network due to its storage facility.

10. IPTV based networks are practically immune to interference, ghosting, harmonics, reflections, cross modulation and so forth - problems that are all frequent in analogue systems. Digital transmission over the coaxial networks signify that some of these issues have been resolved, nevertheless, these still suffer from some of the above.

An Interesting Use of IPTV Technology

A classic illustration of how IPTV technology is being employed in an increasingly inventive number of products, is with a luxurious, IP enabled bathroom television. These TVs are the ultimate in bathroom opulence, permitting the viewer safely to view television whilst soaking in a bathtub full of bubbles, or even taking a shower.

These products provide a convenient and simple solution to hotels worldwide who are adopting the installation of digital IPTV networks across their properties. No more will they have to conceal an STB in the void behind the bathroom or shower wall and install a separate IR receiver, but instead just feed an ethernet cable into the back of the screen to deliver television, radio, VOD and any additional services which the hotel chooses to provide.

Now that is luxury!

Wireless CCTV - Dynamic DNS For Beginners

Wireless internet CCTV, also known as IP CCTV, communicates through your broadband line and onwards to the internet. This can cause problems if your home broadband has a dynamic IP address, because when you want to connect to your cameras from outside, you won't know what that address is. This article shows you how to overcome the problem by using Dynamic DNS.

Most home ADSL packages still give you a dynamic or changing IP address, which is simply the address of your home's network on the internet. These addresses are allocated from a pool of available addresses and allow the internet provider to have fewer addresses than customers, saving money. This used to work well because early broadband modems "dialled" a connection when the attached computer requested it, rather like the old dial-up modems. Nowadays, though, modern wireless modem/routers tend to remain connected permanently, so we are reaching the point where the internet provider is having to allow one IP address per customer, and may as well allocate a static or unchanging one. However, as of today most people have dynamic addresses and this is an obstacle to contacting your wireless internet camera from the outside world, as I will explain in the next section.

Just as your broadband line has an IP address, so your camera has its own address or port. For example, if your home IP address is and the camera's port is 8765, assuming your router is set up with port forwarding (outside the scope of this article) you can contact your camera by typing "http://" into a browser window. This may work today, but by tomorrow that IP address could have been allocated to someone else, and you will not find your camera on the end of it any more. This is where Dynamic DNS or just "DDNS" comes in.

DDNS allows you to contact your wireless internet CCTV camera using an address that never changes, even when your broadband's IP address changes. It requires two things in order to work: a DDNS service provider and a router or camera that offers DDNS support. Most modern wireless routers offer DDNS support, but few internet CCTV cameras do. As long as either the camera or the router offers this feature, all is well. First, you visit the website of the DDNS service provider and sign up for an account. The most popular provider is dyndns.com and it's free. You choose your own unique internet address such as "mywirelesscamera.dyndns.org" and you will also have a user name and password. (Incidentally, the purpose of this service is simply to make that link between your IP address, whatever it happens to be at the time, and a fixed address or domain name.) Having registered a DDNS account, next you log into your router's administration pages and find the DDNS section. Here you simply key in the DDNS provider name, your account details and the address that you chose. Now, whenever your broadband provider changes your home IP address, your router will tell dyndns.com, and this means you can always contact your camera from wherever you happen to be, by keying the same unchanging address into a browser window, in our example: "http://mywirelesscamera.dyndns.org:8765".

There are a lot of myths surrounding Dynamic DNS. I hope this article has exploded a few of them and given you enough information to keep your wireless internet cameras accessible from the internet.
