What Are The Bandwidth Requirements For IPTV Implementation?

Many see IPTV as the “subsequent large component”. However, frequently both vendors and customers are unclear on one of the most fundamental tenants of IPTV great capability. The desired bandwidth. So… Simply what’s the minimal bandwidth so one can supply a “exact” film experience?

In reality, the query posed in the ones terms does now not make numerous feel.

As a count of fact you must think about the resolution in pixels of the video. Instance, for a 16:nine broadcast the numbers are as follows:




The frame rate can be 24, to healthy the cameras used to movie films.

Then you definately ought to recollect the codec in use to compress the picture ….. And the bitrate you need to use.

Then you must move directly to the audio component. Again you have to use the ideal codec and bitrate.

The tv set used plays an critical role as well. As an instance, a 52 inch 16:9 lcd/plasma flat panel will show extra artifacts than a 32 inch analogue 16:9 CRT television.

Additionally the media could be a notebook or a cellular phone rather than a tv…

As said in advance, this is a difficult question to answer and all of it relies upon for your community design to be sincere. Some providers have executed HD nice streams at a constant 1Mbps and regarded it on a 50+ inch plasma …. Which wow’d customers. iptv lista One pattern company streamed a maximum 8 periods on a demo from eight special nations via MPLS ….. And has a multicast stream of about 2.5Mbps in HD.

MPLS allows ….. But you have to take into account that your community engineers have to recognize multicasting extraordinarily well, in addition to QoS. Plus your device have to now not slack. MPLS means nothing if your community is engineered improperly. It additionally way not anything in case your MPLS issuer is clueless ….. And or peering with someone else who isn’t always honoring packet coloring.

Normally speakme, there are quite some variables as to how a lot bandwidth is needed. On ITVN and Fios structures, 1.2Mbps appears to deliver 480 equal video and 5.1 audio. HD content commonly requires at least 5 Mbps. The most important trouble typically seen is the regular availability of bandwidth. If there are a couple of users in a family or in the identical area, the bandwidth fluctuations can purpose buffering and degrade the image exceptional. You can additionally see latency issues strolling ping tests or excessive pings.

That allows you to simply expect (IPTV) Bandwidth necessities on equipment selection and deployment it’s far beneficial to have a base start line for simultaneous Multi – Play provider shipping to the digital home.That makes feel as a Portofolio presenting and not keeping apart the streams vs. The entire package deal when predicting ability.

The initial assumption would include 2 x general Definition (SD) and one high Definition (HD) tv streams ….. And let’s assume 3 Voice over IP (VoIP) telephones along side some streaming digital audio/song.

The usage of H.264 this B2C primary scenario indicates a minimal bandwidth requirement of 15 megabits (not 6 Mbps) .

This maximum probably will increase as HD content material is turning into more ubiquitous and HD-capable presentations are performing increasingly in every home.

The planning oldsters inside your orginization ought to bear in mind that there will be about three simultaneous HD streams – usually and nowadays the common range of streams consistent with family. This means about 24 megabits provide or take… With out even thinking about the capability future programs (e.G. Video telephony , personal broadcast).
With potential destiny applications ….. The bandwidth required to the digital domestic may go up to 50Mbps!

As for planning from an Operator’s point of view – understand that IPTV is a main investment crucial to the success to your orginization. Not to be stressed with WebTV which is a step earlier than (complete) IPTV.

With this in thoughts choose your Bandwidth service vendors (BSP) carefully. There may be extra to recollect than just cost. A stable Tier 1 issuer with a stable SLA (provider stage agreement) and QoS (first-rate of service wellknown) is a must.

Try and paintings with your preferred BSP on potential making plans and Backhaul. Validate four primary important investments: 1 to six months , 6 months to at least one year. , 1 12 months. To a few yrs. And three yrs. To five yrs. Try and use a MPLS backbone to the entire quantity that you can. (word: you may get lot of capability packages on top of it afterward as likely move to “smart” BackHaul.)

Once more ….. Ensure you take into consideration the HD implications as mentioned above with the intention to double your bandwidth requirements according to household served.

You will incur substantial investment in case you plan to offer IPTV. It is not best approximately Fiber Optics to the Premises/houses ….. However also the whole backhaul layout plus the shipping and enablement of such capacity. Therefore my thought(s) to technique your BSP with a few kind of partnering association (at least in the early tiers) to proportion the business Case in a reasonably win-win proposition (retaining your preliminary fees decrease).
