What are Bandwidth Requirements For IPTV Implementation?

Many see IPTV as the “next big thing”. Having said that, often equally suppliers and users are usually ambiguous on one involving the most basic tenants of IPTV quality usefulness. The required bandwidth. Therefore… just what is the minimum bandwidth that can give a “good” flick experience?

Truly, this question presented in individuals terms will certainly not help to make a lot of perception.

As a matter connected with fact you must acquire into consideration the resolution in pixels from the online video media. Example, for a 16: 9 broadcast the statistics are as follows:




The shape rate is going to be 24, to help match the camcorders made use of to film movies.

Then you definitely should consider the codec used to compress often the image….. along with the bitrate a person want to use.

Then you definitely must move on in order to the stereo part. Once again you should use a suitable codec and bitrate.

The TV set used plays a vital role as well. To get example, a 52 half inch 16: dokuz LCD/plasma even panel reveals more artifacts than a 34 in analogue 16: 9 CRT TV.

Also the press could be a portable computer or perhaps a mobile cellphone rather of an TV…

As stated earlier, this is the complicated question to answer and it also all depends on your own personal network design and style to be trustworthy. Some vendors have got done HD quality revenues on a constant 1Mbps together with viewed it with the 50+ inch flat screen…. which will wow’d clients. One trial provider streamed a new utmost 8 sessions upon some sort of demo from almost eight various countries via MPLS….. and has now a multicast stream of about 2. 5Mbps throughout HIGH-DEFINITION.

MPLS helps….. nonetheless you have to keep in mind that your network planners should know multicasting incredibly well, in addition to QoS. As well as your equipment should never slack. MPLS means nothing in the event that your network is built improperly. It also implies nothing at all if your MPLS provider can be clueless….. together with or peering together with a person else who else is not necessarily praising supply coloring.

Commonly speaking, you can find quite a good few variables as to be able to the amount bandwidth is needed. On ITVN and Fios systems, one 2Mbps seems to deliver 480 counterpart video and your five. 1 audio. HD articles generally requires at least 5 various Mbps. The biggest challenge normally seen is often the consistent accessibility to bandwidth. In case there are various people in a house or in the same area, typically the bandwidth variances can certainly cause buffering and decay the picture top quality. A person may also see latency difficulties running ping assessments as well as excessive pings.

In order to be able to definitely predict (IPTV) Bandwidth Prerequisites on equipment assortment plus deployment it is valuable to own a trust starting point with regard to sychronized Multi – Have fun Services Delivery to the A digital Home. That makes good sense to be a Portofolio offering and not isolating the avenues vs. the whole package as soon as couples total capacity.

The initial predictions would contain two x Standard Description (SD) and one High Classification (HD) TV streams….. together with maybe three Voice more than IP (VoIP) cell phones together with some streaming a digital audio/music.

Using H. 264 this B2C basic circumstance suggests a minimum band width requirement of 15 megabits (ofcourse not six Mbps).

This most probably will increase as HIGH DEFINITION content is starting to become more all-pervasive and HD-capable displays will be appearing more and more in just about every home.

The planning individuals within your orginization include to remember there’ll possibly be about three sychronized HIGH-DEFINITION streams – usually together with nowadays the average amount of streams per house. This implies about 24 megabits give or take… without even taking into consideration the potential future applications (e. g. video telephone, individual broadcast).
With possible future applications….. the bandwidth necessary to the Digital Residence may well go up to be able to 50Mbps!

Concerning planning coming from an Operator’s mindset instructions know that IPTV can be a major investment decision vital to the success for your personal orginization. Not to get mistaken for Norsk TV i Utlandet which will be a step just before (full) IPTV.

With this in mind choose your Bandwidth Service Providers (BSP) properly. There’s more to think about in comparison with just cost. A stable Rate 1 provider having a strong SLA (Service Level Agreement) and QoS (Quality involving Service standard) is some sort of MUST.

Attempt to work with your selected BSP on Capacity Planning and Backhaul. Validate 5 major critical investments: a single to 6 months, 6 weeks to 1 month., 1 month. to 3 or more years. and a few years. to 5 yrs. Try to use a MPLS central source fully extent that you may. (Note: you can find lot regarding potential applications along with the idea later on as very likely move to “Intelligent” BackHaul. )

Again….. make positive you take into thought the HD implications because described above which is going to double the bandwidth demands per home served.

You are going to get substantial investment if you plan to present IPTV. It is certainly not only about Fiber Optical technologies to the Premises/Homes….. yet likewise the whole backhaul design and also transport and enablement of such potential. Thus the suggestion(s) to help approach your BSP together with some type of partnering arrangement (at least inside the early stages) to promote this company Case in a fairly win win proposition (keeping your original costs lower).
