Many see IPTV as the next big thing. However both users and providers are uncertain on a few of the fundamental tenants of IPTV quality performance. The bandwidth that is required. So just what is the minimal bandwidth which will provide great movie experience actually, the question does not make plenty of sense. As A matter of fact you need to take the resolution in pixels of the movie. Example, to get a 16:9 broadcast the amounts are as follows: As Stated this is a challenging question and it depends to be honest. Some suppliers have done HD quality streams at a constant 1Mbps and seen it on 50+ inch plasma. Which wow would clients 1 sample supplier streamed a maximum 8 sessions on a demo from 8 different nations via MPLS. And has a multicast flow of approximately 2.5Mbps in HD.MPLS helps. However, you need to bear in mind your network engineers must know multicasting Quos, in addition to well. Plus your gear should not slack. Additionally, it means nothing if your MPLS supplier is clueless. And or peering with somebody who is not currently honoring packet coloring.
Generally Regarding how much bandwidth is needed, there are a number of variables. On ITVN and Foist systems, 1.2Mbps appears to deliver 480 equal video and 5.1 sounds. HD content requires at least 5 Mbps. The issue is that the availability of see more bandwidth. If there are many users in the area or in a home, the bandwidth changes can lead to buffering and degrade the image quality. You could see problems running tests or pings that are excessive. To be able to really predict IPTV Bandwidth Requirements on gear selection and deployment it is beneficial to have a base starting point for simultaneous Multi – Play Service Delivery to the Digital Home. That makes sense as a Portfolio offering rather than separating the flows vs. the entire package when calling capacity. The First assumption would comprise 2 x Standard Definition SD and one High Definition HD TV flows. And let us say three Voices over IP VoIP phones together with some streaming electronic audio/music.
Using H.264 this B2C basic situation suggests a minimum bandwidth requirement of 15 megabits not 6 Mbps. This most increases screens are emerging more and more in each home and as HD content are becoming ubiquitous. The Planning folks inside your organization need to keep in mind that there will be about three HD flows – and nowadays the number of flows per household. This means about 24 megabits give or take without even considering the possible future programs e.g. video telephony, personal broadcast with possible future applications. 50Mbps may be gone up to by the bandwidth! As for planning with the standpoint of an Operator – know that IPTV is an important investment.
