Market Trends & Insights

• SRT Protocol Dominance: SRT adoption has reached 78% among broadcast professionals, largely replacing older protocols due to its "packet recovery" features on jittery connections. Alibaba
• Hybrid Infrastructure Demand: 82% of commercial venues (hotels/stadiums) still utilize coaxial cabling. Instead of expensive fiber rewiring, there is surging demand for IPTV-to-RF gateways that deliver modern IP content over existing coax. ThorbroadcastAlibaba
• Market Growth: The global modulator market is projected to grow at a CAGR of ~6.6% through 2031, driven by the ATSC 3.0 (NextGen TV) rollout in North America and the push for 4K UHD content in digital signage. AlibabaDataintelo
