What are Bandwidth Requirements For IPTV Implementation?

Many see IPTV as the “next large thing”. Even so, often the two suppliers and users are not clear on one regarding the most basic renters of IPTV quality operation. The required bandwidth. Therefore… what is the minimum band width that will give a “good” video experience?

Actually, the particular question presented in all those terms will not make a lot of perception.

As a matter involving fact you must consider into consideration the solution in pixels on the movie. Example, for a sixteen: 9 broadcast the figures are as follows:




The structure rate will probably be 24, for you to match the video cameras used to film movies.

Then you definitely should consider the codec available to compress typically the image….. along with the bitrate anyone want to use.

Then you must move on for you to the sound part. Once again you should use an appropriate codec and bitrate.

The TV set used plays an important role as well. For example, some sort of 52 half inch 16: on the lookout for LCD/plasma toned panel will show more artifacts than a thirty two inch analogue 16: 9 CRT TELLY.

Also often the mass media could be a notebook as well as a mobile cellphone alternatively of any TV…

As stated earlier, that is a tough question to answer and it all depends on your current network layout to become honest. Some providers possess done HD quality fields from a constant 1Mbps in addition to viewed it upon the 50+ inch cruor…. which usually wow’d clients. A person small sample provider streamed a good maximal 8 sessions with a new demo from 6 different countries via MPLS….. and it has a multicast stream of about 2. 5Mbps around HARLEY-DAVIDSON.

MPLS helps….. nevertheless you have to use in imagination that your network technicians should know multicasting highly well, as well as QoS. In addition your equipment probably should not slack. MPLS means nothing when your network is constructed improperly. It also suggests little or nothing if your MPLS provider is definitely clueless….. together with or peering using a person else who is not adoring packet coloring.

Generally speaking, you will discover quite the few variables as to help the amount of bandwidth is required. On ITVN and Fios systems, 1 . 2Mbps looks to deliver 480 comparative video and 5 various. one audio. HD content material commonly requires at least a few Mbps. The biggest challenge normally seen is often the consistent accessibility to bandwidth. In the event there are numerous people in a family or in the same location, often the bandwidth changes can easily cause buffering and lower the picture quality. Anyone may also see latency concerns running ping exams as well as excessive pings.

For you to be able to really predict (IPTV) Bandwidth Prerequisites on equipment choice plus deployment it is practical to possess a starting starting point regarding synchronous Multi – Carry out Support Delivery to the Electronic digital Home. That makes good sense being a Portofolio offering plus not distancing the revenues vs. the entire package as soon as couples total capacity.

The original premiss would incorporate two x Standard Description (SD) and one High Description (HD) TV streams….. together with parenthetically three Voice in excess of IP (VoIP) cell phones coupled with some streaming digital audio/music.

Using H. 264 this B2C basic scenario suggests a minimum bandwidth requirement of 15 megabits (ofcourse not 6th Mbps).

This most probably raises as HI-DEF content is starting to become more common and HD-capable displays happen to be appearing more and more in just about every home.

The planning persons within your orginization have got to remember there’ll always be about three sychronized HD streams – typically and nowadays the average variety of streams per household. This means about 24 megabits provide or take… without uniform considering the potential future purposes (e. g. video telephone, particular broadcast).
With possible potential future applications….. the bandwidth forced to the Digital Home might go up for you to 50Mbps!

As for planning coming from an Operator’s viewpoint — recognize that IPTV is usually a good major investment decision essential to the success on your orginization. Not to be mistaken for WebTV which can be a step just before (full) IPTV.

With this found in mind decide on your Band width Service Providers (BSP) cautiously. There’s more to consider in comparison with just cost. A stable Tier 1 provider together with a solid SLA (Service Level Agreement) and QoS (Quality of Service standard) is the MUST.

Attempt to work with your selected BSP on Capacity Planning and Backhaul. Validate five major critical investments: you to 6 months, a few months to 1 365 days., 1 year. to three or more years. and 3 years. to 5 yrs. Use a MPLS spine to the full level that you can. (Note: Abonnement IPTV can receive lot associated with potential applications along with this later on as likely move to “Intelligent” BackHaul. )

Again….. make positive you take into concern this HD implications since mentioned above which will definitely double your current bandwidth prerequisites per home served.

You will accumulate essential investment if you plan to present IPTV. It is not necessarily only about Fiber Optics to the Premises/Homes….. nevertheless furthermore the whole backhaul design in addition to the transport and even enablement of such capacity. Thus my own suggestion(s) to help approach your current BSP having some type of partnering arrangement (at least within the early stages) to reveal the organization Case in a good fairly win win proposition (keeping your initial costs lower).
