Confirmed expertise
What we engineer
Every capability below is in production use, described in the terms the specifications themselves use.
Adaptive streaming pipelines
HLS, LL-HLS, CMAF, DASH end-to-end. Per-title encoding ladders, ABR logic, and manifest generation built and QC'd against the published Apple HLS Authoring, Netflix Photon and Amazon Prime Video delivery specifications.
Hardware & software encoders
NETINT Quadra VPU T1A/T2A, NVENC, Intel Quick Sync, AMD VCN for hardware acceleration. x264, x265, SVT-AV1, VVenC for software paths. Codec selection matched to latency and cost targets.
Multi-DRM content protection
FairPlay, Widevine and PlayReady with CENC and cbcs encryption schemes. Key rotation, licence server integration and PSSH box generation.
Broadcast & ad insertion
IMF (SMPTE ST 2067) packaging, HLS Interstitials, SCTE-35/104 cue injection and AI-driven ad-break detection on content signals.
Quality metrics & QC
VMAF, PSNR, SSIM computed per segment and surfaced in an operations dashboard. Automated QC gates before segment packaging.
Observability
OpenTelemetry tracing through encode → package → origin. Kafka event streams for segment-level telemetry. Alerts on stall rate, latency and error spikes.

Built against published delivery specifications
Netflix Photon conformance
Output packages run through Netflix Photon conformance tooling. CMAF segment structure, timing metadata and codec constraints are validated against the published Photon requirements before delivery.
Apple HLS Authoring Specification
Manifests and segments validated against the Apple HLS Authoring Specification for HEVC, FairPlay encryption and HLS Interstitials. Bitrate ladder and timing requirements checked against the published authoring guidelines.
Amazon Prime Video ingest
Encoding ladders and packaging aligned with the Amazon Prime Video documented ingest profile, including HDR metadata passthrough and audio normalisation per the published requirements.
