Many see IPTV as the “next huge thing”. Having said that, often both equally services and users are usually not clear on one connected with the most basic renters of IPTV quality usefulness. The required bandwidth. Consequently… just what is the minimum bandwidth that can give a new “good” flick experience?
Basically, often the question posed in individuals terms will do not necessarily produce a lot of good sense.
As a matter associated with fact you must have into consideration often the solution in pixels in the online video media. Example, for a 16: 9 broadcast the figures are as follows:
The shape rate will likely be 24, to be able to match the digital cameras employed to film movies.
Then you definately should consider the codec available to compress the particular image….. along with the bitrate anyone want to use.
Then atlaspro must move on to the audio tracks part. Yet again you should use an appropriate codec and bitrate.
The TV set used plays a crucial role as well. With regard to example, a good 52 half inch 16: dokuz LCD/plasma smooth panel displays more artifacts than a 32 in analogue 16: nine CRT TV.
Also the advertising could be a laptop computer or maybe a mobile phone instead of the TV…
Since stated earlier, it is a challenging question to answer also it all depends on your network design to get trustworthy. Some services have done HD quality streams in a constant 1Mbps in addition to viewed it with some sort of 50+ inch lcd…. which often wow’d clients. A single small sample provider streamed the maximum 8 sessions in the demo from 8 different countries via MPLS….. and has now a multicast steady stream of around 2. 5Mbps around HIGH-DEFINITION.
MPLS helps….. nonetheless you have to keep in mind that your network planners should know multicasting really well, in addition to QoS. In addition your equipment should never slack. MPLS means zero in the event your network is engineered improperly. That also implies zero if your MPLS provider is definitely clueless….. and or peering using an individual else who also is not necessarily honoring package coloring.
Generally speaking, there are quite the few variables as in order to how much bandwidth is recommended. On ITVN and Fios systems, 1 . 2Mbps appears to be to deliver 480 equal video and your five. one particular audio. HD material generally requires at least 5 various Mbps. The biggest issue typically seen is the consistent accessibility to band width. When there are various end users in a home as well as in the same place, often the bandwidth variances can cause streaming and break down the picture level of quality. Anyone may also see latency issues running ping tests or even excessive pings.
To help be able to really predict (IPTV) Band width Specifications on equipment selection in addition to deployment it is beneficial to own the trust starting point with regard to sychronizeds Multi – Take up Services Delivery to the Digital Home. That makes sense to be a Portofolio offering and even not removing the fields vs. an entire package whenever forecasting ability.
The original supposition would incorporate two x Standard Explanation (SD) and one High Description (HD) TV streams….. and let’s imagine three Voice in excess of IP (VoIP) cell phones along 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 just about all probably raises as HARLEY-DAVIDSON content has become more ubiquitous and HD-capable displays can be appearing progressively more in every single home.
The planning individuals within your orginization include to keep in mind there’ll end up being about three simultaneous HI-DEF streams – generally plus nowadays the average variety of streams per home. This means about 24 megabits give or take… without uniform taking into consideration the potential future software (e. g. video telephone, private broadcast).
With possible future applications….. the band width forced to the Digital Property may possibly go up in order to 50Mbps!
As for planning through an Operator’s standpoint : recognize that IPTV is the major investment decision crucial to the success for your orginization. Not to become confused with WebTV which will be a step before (full) IPTV.
With this inside mind decide on your Band width Service Providers (BSP) meticulously. There’s more to think about as compared to just cost. A stable Tier 1 provider with a solid SLA (Service Level Agreement) and QoS (Quality associated with Service standard) is a good MUST.
Consider to work with your chosen BSP on Capacity Planning and Backhaul. Validate four major critical investments: just one to 6 months, half a dozen several weeks to 1 month., 1 month. to three or more yrs. and three or more years. to 5 yrs. Use a MPLS backbone to the full level that you can certainly. (Note: you can receive lot connected with potential applications along with the idea later on as most likely move to “Intelligent” BackHaul. )
Again….. make confident you take into thing to consider the particular HD implications since pointed out above which can double your own personal bandwidth needs per household served.
You’ll incur considerable investment in the event you plan to offer IPTV. It is not only about Fiber Optical technologies to the Premises/Homes….. but as well the whole backhaul design as well as the transport and even enablement associated with such total capacity. Thus our suggestion(s) to approach your BSP together with some type of partnering arrangement (at least within the early stages) to discuss the company Case in the fairly win-win proposition (keeping your initial costs lower).
