Many see IPTV as the “next major thing”. Nevertheless, often each services and users are unsure on one involving the most basic tenants of IPTV quality functionality. The required bandwidth. Consequently… just what is the minimum band width that can give a “good” video experience?
Truly, often the question presented in these terms does not help to make a lot of sense.
As a matter of fact you must have into consideration the image resolution in pixels of the movie. Example, for a of sixteen: 9 broadcast the statistics are as follows:
704×480
1280×768
1920×1080
The structure rate will likely be 24, to help match the video cameras used to film movies.
Then you definitely should consider the codec available to compress this image….. plus the bitrate an individual want to use.
Then you must move on to the music part. Yet again you should use the ideal codec and bitrate.
The TV set used plays a crucial role as well. Intended for example, a new 52 in . 16: dokuz LCD/plasma level panel displays more artifacts than a thirty two in . analogue 16: 9 CRT TV.
Also often the media could be a portable computer or a mobile cellphone alternatively of the TV…
Since stated earlier, it is a difficult question to answer also it all depends on your network design and style to turn out to be truthful. Some suppliers have got done HD quality revenues on a constant 1Mbps in addition to viewed it in a 50+ inch sang…. which often wow’d clients. A single sample provider streamed a greatest 8 sessions on a good demo from eight diverse countries via MPLS….. and it has a multicast supply around 2. 5Mbps within HIGH DEFINITION.
MPLS helps….. nevertheless you have to keep in brain that your network engineers should know multicasting highly well, in addition to QoS. In addition your equipment should not slack. MPLS means little or nothing when your network is engineered improperly. almsat.com signifies nothing at all if your MPLS provider is definitely clueless….. plus or peering along with anyone else who else is definitely not adoring supply coloring.
Usually speaking, you can find quite the few variables as to be able to the amount bandwidth is needed. On ITVN and Fios systems, one 2Mbps would seem to deliver 480 counterpart video and a few. one audio. HD content commonly requires at least your five Mbps. The biggest issue usually seen is the particular consistent accessibility to bandwidth. In the event that there are numerous consumers in a household or in the same area, the bandwidth fluctuations will cause streaming and degrade the picture good quality. You may also see latency issues running ping checks or excessive pings.
To be able to truly predict (IPTV) Band width Needs on equipment collection plus deployment it is useful to have got the bottom starting point to get sychronizeds Multi – Carry out Assistance Delivery to the A digital Home. That makes feeling being a Portofolio offering and even not isolating the channels vs. the full package when couples total capacity.
The preliminary supposition would include 2 x Standard Meaning (SD) and one High Definition (HD) TV streams….. and let’s imagine three Voice in excess of IP (VoIP) phones together with some streaming online audio/music.
Using H. 264 this B2C basic case suggests a minimum band width dependence on 15 megabits (not 6 Mbps).
This almost all probably raises as HIGH DEFINITION content is now more ubiquitous and HD-capable displays are appearing increasingly more in each home.
The planning persons within your orginization possess to remember there’ll end up being about three coexisting HARLEY-DAVIDSON streams – normally plus nowadays the average variety of streams per household. Therefore about 24 megabits give or take… without including considering the potential future programs (e. g. video telephone, personalized broadcast).
With possible prospect applications….. the bandwidth instructed to the Digital Residence may well go up to help 50Mbps!
Concerning planning coming from an Operator’s standpoint : recognize that IPTV is some sort of major expenditure essential to the success for your orginization. Not to turn out to be mistaken for WebTV which can be a step before (full) IPTV.
With this at mind select your Band width Service Providers (BSP) carefully. There’s more to think about in comparison with just cost. A steady Tier 1 provider using a sturdy SLA (Service Level Agreement) and Quality of service (Quality involving Service standard) is the MUST.
Try out to work with your chosen BSP on Capacity Preparation and Backhaul. Validate 5 major critical investments: one to 6 months, a few a few months to 1 365 days., 1 365 days. to a few yrs. and 3 or more yrs. to 5 yrs. Use a MPLS central source to the full level that you can easily. (Note: you can receive lot regarding potential applications together with it later on as most likely move to “Intelligent” BackHaul. )
Again….. make sure you take into consideration typically the HD implications as described above which will certainly double the bandwidth demands per household served.
You will still bear essential investment in case you plan to give IPTV. It is certainly not only about Fiber Optics to the Premises/Homes….. but furthermore the whole backhaul design together with transport together with enablement of such ability. Thus our suggestion(s) to help approach the BSP together with some type of joining up arrangement (at least inside early stages) to reveal the organization Case in a new fairly win-win proposition (keeping your original costs lower).
