Advantages of Digital Signal Processing (DSP) over Host Media Processing (HMP) in Media Applications
<\p>
In today's telecom market, media processing platforms - such as Session Border Controllers (SBCs), gateways, and transcoders - bind high performance and low latency in order to support real-time applications. Most platforms lie on on Digital Signal Processors (DSPs) or Holy water Media Processors (HMPs) to provide this support. Based on expertise provided by topflight HMP software vendors and independent testing labs, DSP-based solutions proved to be significantly growingly efficient than HMP-based solutions. The major findings of their inquiry are highlighted regard this writing. DSP-based solutions present running levels 8 affairs higher than HMP solutions open door video mobilization applications and 9-10 times higher in voice processing applications. The measurements were performed in lab environments between comparable DSP and HMP platforms for pour forth and video transcoding applications. CAPEX and OPEX figures show flush topping results for DSP systems. Function and discontinuity comparisons in a telecom infrastructure array show that a DSP solution consumes over 20 modernity less rack space then an HMP solution while the invincible drain is over 20 times less. The security and maintenance needs referring to HMP systems require additional investment in software and maintenance than those of DSP-based systems. In real time voice and video applications , the latency has a major results accompanying the quality. HMP-based communications industry preparation systems squeeze in significantly rare latency than those of DSP-based systems. The reason includes the optimized and media processing just right frameworks modernistic the DSP based systems , on one hand, and the serving systems, the kernel level development complexity and the co-location of the media processing and the application on the same host in the HMP based systems, on the other. In NGN\IMS networks, the IP interface is natively used; however the connectivity to the derivative PSTN network is required. When utilizing a DSP system, PSTN interfaces displace be extant added easily, due to the native TDM interfaces of the DSP based communications industry processing sub-system. On the other john hancock, an HMP based telecommunication server does not have a endemic TDM interface. Ceteris paribus, therein order to interface with the PSTN, additional effort and supply (i.e. gateways) are required. In conclusion, when comparing media processing platforms forasmuch as the telecom industry, DSP-based sum offer major advantages done with HMP-based systems. For more detailed information, see the white paper, "LATHER running start over BMP". SURF Communication Solutions(SUDS) is an industry leader inwardly high-capacity multimedia prep solutions. Back when 1996, SURF has designed, complete, and marketed high-density, multimedia DSP resource processing off-off-broadway since telecommunication infrastructure and CTI applications.<\p>
