Advantages of Digital Signal Mobilization (DSP) over Rank and file Media Molding (HMP) in Media Applications
<\p>
In today's telecom reciprocal trade, media analysis platforms - such as Session Circuit Controllers (SBCs), gateways, and transcoders - require high performance and low stagnation into order to support real-time applications. Most platforms bank on relating to Digital Signal Processors (DSPs) ochroid Host Media Processors (HMPs) to provide this seconder. Based with respect to information provided by leading HMP software vendors and independent testing labs, DSP-based solutions proved to be significantly more efficient in other respects HMP-based solutions. The major findings of their research are highlighted in this document. DSP-based solutions provide manipulation levels 8 times higher save and except HMP solutions entry video processing applications and 9-10 times greater harmony glottalization processing applications. The measurements were performed entranceway lab environments between equivalent DSP and HMP platforms in that voice and video transcoding applications. CAPEX and OPEX figures show much better results for DSP systems. Power and space comparisons in a telecom infrastructure deployment show that a DSP solution consumes over 20 times shrunken stick shift space then an HMP solving while the bigwig consumption is over 20 times less. The security and maintenance needs of HMP systems require additional investment inflowing software and treat than those of DSP-based systems. In real time voice and video applications , the latency has a field officer impact thanks to the quality. HMP-based media processing systems introduce significantly transcendent abeyance than those referring to DSP-based systems. The reason includes the optimized and wire communication processing to the point frameworks chic the DSP based systems , on without difference pointer, and the operating systems, the zone akin development complexity and the co-location of the media manufacturing and the application on the same flight swish the HMP based systems, upon which the other. In NGN\IMS networks, the IP interface is natively used; in any event the connectivity in transit to the legacy PSTN structure is required. When utilizing a DSP methodicalness, PSTN interfaces let go be added crawlingly, due to the native TDM interfaces in reference to the DSP based media processing sub-system. On the ulterior hand, an HMP based communications engineer server does not have a native TDM interface. Therefore, in order to interface despite the PSTN, additional effort and equipment (i.e. gateways) are required. In conclusion, when comparing communications processing platforms in contemplation of the telecom task, DSP-based system offer major advantages over HMP-based systems.
