Intinor details redundant SRT and SMPTE 2022-7 for broadcast uptime
Intinor technical leads provide a webinar session detailing methods for ensuring broadcast uptime over public internet using redundant SRT and SMPTE 2022-7 standards. The session also addresses bandwidth requirements for 10-bit 4:2:2 workflows and compares the efficiency of AVC versus HEVC encoding.
Key Takeaways
- Redundant SRT with SMPTE 2022-7 allows identical data packets to travel over diverse ISP routes for hitless protection switching.
- Webinar analysis details bandwidth variations between 8-bit and 10-bit color depth and 4:2:0 versus 4:2:2 chroma subsampling.
- Integrated workflows use adaptive bitrate, network bonding, and forward error correction (FEC) to mitigate packet loss.
- Collaboration with Eurovision Services validated interoperability of RTP over SRT with SMPTE 2022-7 for multi-vendor environments.
Why It Matters
Broadcasters are increasingly shifting away from dedicated fiber and satellite toward public internet for primary live contribution to reduce operational expenses. Implementing standardized redundancy protocols like SMPTE 2022-7 is critical because it eliminates the single point of failure inherent in unmanaged IP links while ensuring vendor interoperability. As the industry moves toward 10-bit HDR production, managing the resulting bandwidth surge without sacrificing signal precision becomes the primary engineering challenge. Watch for increased adoption of multi-path SRT in Tier-1 sports events throughout 2026 as legacy SDI infrastructure continues to be replaced by software-defined IP networking.
Additional Context
The transition to IP-based contribution has reached a critical tipping point in 2026. According to the Haivision 2026 Broadcast Transformation Report, SRT adoption among broadcast professionals has grown to 78%, up from 47% in 2020. This growth is driven by the flexibility required for remote production, which 41% of broadcasters now identify as their leading technology priority. While traditional SDI still dominates at 82% of facilities, the adoption of SMPTE standards for IP transport is steadily increasing, with ST 2110 usage growing by 4% year-over-year as of March 2026. This shift reflects a broader industry movement toward building more resilient, internet-based delivery pipelines that offer satellite-level reliability at a lower cost. Market analysis from DataHorizzon Research in July 2026 projects the next-generation video codec market will reach 8.92 billion USD by 2033, expanding at a CAGR of 15.3%. This expansion highlights the urgent need for the bandwidth efficiency and signal precision discussed by Intinor, particularly as 4K and 8K content demand more robust compression. Simultaneously, companies like Veset and AWS have integrated SMPTE 2022-7 support into cloud playout and media connect services, further standardizing seamless protection switching across highly distributed hybrid-cloud workflows. By mid-2026, these interoperable protocols have become the de facto requirement for broadcasters managing the upcoming 2026 FIFA World Cup, where traffic spikes and network congestion necessitate true path redundancy.
