Description

Advanced coding and modulation technologies, often used in various combinations, offer a quantum-leap in efficiency that brings structural changes to the ground segment business of most satellite-delivered applications. Satellite sectors and applications that benefit from advanced modulation and/or video compression include DTH, video distribution and contribution, satellite broadband and IP trunking/backhaul, HITS, digital cinema distribution and SCPC.

DVB-S2 modulation and MPEG-4 AVC (H.264) video compression have been widely accepted as the prevalent standardized means to optimize satellite links in video broadcast and point-to-multipoint (P2MP) networks. Nevertheless, business and technical conditions are also inducing the use of non-standard advanced techniques such as frequency reuse and flexible LDPC coding in point-to-point and P2MP scenarios to match new trade-offs associated with bandwidth, power and latency in interactive applications.

Despite wide industry acceptance and validated bandwidth savings, questions remain as to what speed will these advanced technologies be deployed, where and how for the relevant scenarios. Depending on a number of industry and application-specific considerations, the case for deploying advanced systems against traditional systems can vary substantially from region-to-region and from application-to-application. Factors accelerating or deterring new system and migration deployments include HD growth, costs of advanced set top boxes, current/planned satellite footprint and frequency bands, installed base of legacy components, space segment cost, network scale and collective switching issues.

The drivers and contextual considerations for each of the sub-sectors where advanced coding and modulation apply mean regional-specific degrees of adoption speed and tipping points for hardware vendors, operators and service providers to take into consideration when planning deployments in both greenfield and replacement scenarios.

This second edition of NSR's comprehensive study on the advanced coding and modulation market has expanded in scope and depth, with more granularity in equipment forecasts for both end-side and teleport-side equipment, as well as the addition of categories not covered in the 1st edition. This report is the result of extensive research, development of application-specific "bottom-up" forecast models and interviews with industry-leading hardware suppliers and service providers in the sectors of DTH, video broadcast, satellite broadband, IP Trunking, SCPC and digital media distribution.
