The results of Figure 10 indicate that the HT-ERM scheme with CSPF outperforms the other two QSPF and ECMP algorithm beneath the average switch ratio (), while the number of channel joining requests is increasing from 10 to 50. We observe that the traditional PIM-SM multicast using ECMP resulted in the highest blocking ratio due to the traffic aggregation over shared tree with the same routing path, regardless of the multiple parallel links. The resource consumptions are nearly even with those multicast approaches: PIM-SM (ECMP), QMRP (QSPF), and proposed HT-ERM (CSPF) at any channel switching ratio (, 0. 5, 0. 25). For the effect of traffic load balancing, QMRP and HT-ERM scheme can achieve the better link usage performance as compared by PIM-SM while the number of channel joining is increasing to 50. S. This scheme compares two test cases under the same network condition, resolution, and bit rate for a given queuing discipline but with different codecs and determines if they are equivalent or different. Specifically, we perform cross-codec elimination when we know that two codecs perform the same under a given network condition. In contrast to video over the public Internet, with IPTV deployments, network security and performance are tightly managed to ensure a professional experience, resulting in a compelling business environment for content providers, advertisers and customers alike. So a lot for public relations!Lastly, the Poor grade refers to cases where a human subject perceives severe and frequent impairments that make the application unusable. The Acceptable grade refers to cases where a human subject perceives intermittent impairments yet the application is mostly usable.
