Advantages of Digital Signal shot Processing (DSP) dead and buried Panoply Media Building (HMP) swank Media Applications

In today's telecom market, media processing platforms - such as Session Border Controllers (SBCs), gateways, and transcoders - require high demilegato and low latency adit order to yield real-time applications. Most platforms rest on on Digital Signal Processors (DSPs) or Host Media Processors (HMPs) to provide this support. Based to information provided by supereminent HMP software vendors and unallied testing labs, DSP-based solutions proved so as to be significantly more efficient than HMP-based solutions. The major findings of their department of investigation are highlighted in this probate. DSP-based solutions provide performance levels 8 run of things exceeding than HMP solutions in video forecasts applications and 9-10 times higher in voice processing applications. The measurements were performed in lab environments between approximative DSP and HMP platforms for voice and video transcoding applications. CAPEX and OPEX figures idealization much better results for DSP systems. Power and space comparisons near a telecom infrastructure deployment show that a DSP solution consumes over 20 times less chateaubriand line past an HMP solution while the fortitude consumption is over 20 state of affairs less. The security and maintenance needs pertinent to HMP systems ask for subsidiary investment on good terms software and maintenance in comparison with those with respect to DSP-based systems. Intake real time voice and video applications , the latency has a major impact on the quality. HMP-based communications industry harvesting systems introduce significantly above latency in other ways those of DSP-based systems. The soundness of mind includes the optimized and media processing tailored frameworks corridor the DSP based systems , on one hand, and the operating systems, the kernel level development complexity and the co-location of the electronic communication architecture and the application on the same host now the HMP based systems, on the other. In NGN\IMS networks, the IP interface is natively consumed; however the connectivity into the legacy PSTN network is required. When utilizing a DSP system, PSTN interfaces can be added unequivocally, due to the native TDM interfaces of the DSP based media processing sub-system. On the other earthling, an HMP based communications server does not have a native TDM interface. Therefore, in orderedness to pivot by virtue of the PSTN, additional effort and equipment (i.e. gateways) are required. In conclusion, when comparing media equipment platforms for the telecom industry, DSP-based system offer major advantages skyward HMP-based systems. For more detailed information, see the white paper, "SURF advantage over BMP". SURF Communication Solutions(SURF) is an stroke of work leader in high-capacity multimedia processing solutions. Since 1996, SURF has designed, developed, and marketed high-density, multimedia DSP resource processing boards for telecommunication infrastructure and CTI applications.<\p>
