MULTISCREEN UltraHD ENCODING/TRANSCODING

UNIQUE ADVANTAGES

Ultra Low Latency end-to-end

CMAF Ultra Low Latency can dramatically reduce glass to glass latency and is supported by a wide range of HTML-5 compliant players. Currently, the HERO is the only encoder/transcoder that is CMAF ULL qualified by Akamai. HERO today powers reliable OTT services with less than 3.5 seconds end-to-end latency.

Native Virtual Playout

HERO provides an advanced feature that enables File-to-Live workflows based on a dynamic/user-defined playlist, mixing VoD and Live assets. The API-based integration enables CMS/MAM connectivity and full control over the playout (including scrolling texts, overlays, ID3 metadata, ad insertion etc).

Dynamic Clipper

The Clipper feature enables the creation of VoD clips directly from the live delivery workflow and in multiscreen/multi-camera fashion, with minimal time-to-market and without video quality loss. This can be used for File-to-VOD creation on-the-fly or for pulling highlights from a live broadcast for immediate promotion.

Comprehensive High Availability

HERO covers all High Availability architectures and allows for those to co-exist in the same deployment in order to minimize cost with jeopardizing reliability:

  • 1:1 (e.g. sports services) vs. N+M (e.g. generic services)
  • Chassis-level vs. service-level failover
  • Restart-in-place, retry-then-failover, failover-immediately
  • SDI/ASI Router control
  • Up/downstream telemetry and heuristics

Real-time DVB-Subs conversion

HERO is the only solution that supports real-time conversions of DVB-Sub bitmaps to text (DFXP, WebVTT, TTML etc) for over 60 languages. This enables operators to:

  • Improve Video Quality without having burn-in subs
  • Fully customize fonts, colors, placement etc of subtitles
  • Enhance QoE by allowing user-control over the subtitles
  • Maximize compliance with end-user devices

Ad Signaling/Injection

Media Excel’s product portfolio is fully accommodating to ad signaling and insertion workflows. Specifically, HERO supports:

  • In-band SCTE-35, SCTE-104, out-of-band signaling with CableLabs ESAM API
  • GOP, segment conditioning and manifest decoration
  • Ad blocking/replacement, ad-only recording, ad-free recording
  • Native Ad insertion
  • Ad assets transcoding
