VideoonDemandStreamingStandard

VideoonDemandStreamingStandard (VODSS) is an open, vendor-neutral specification intended to standardize the delivery of on-demand video over HTTP networks. It defines a modular framework for encoding, packaging, transport, metadata, accessibility, and rights management to enable interoperability across devices, platforms, and content providers.

Encoding and codecs supported include contemporary video codecs such as AVC, HEVC, and AV1, as well as common audio formats like AAC and Dolby Digital Plus. Packaging and delivery rely on fragmentation of media files (CMAF/ISO base media file format) and HTTP-based adaptive streaming through manifest documents. The standard is compatible with multiple manifest formats, including MPEG-DASH (MPD) and HLS (M3U8), to facilitate cross-vendor playback with consistent segment structures.

DRM and rights management are addressed via interoperable license acquisition models for major DRM schemes, including Widevine, PlayReady, and FairPlay, with guidance on license lifecycle, renewal, and revocation. The standard also supports content protection features such as watermarking interfaces where applicable.

Metadata, accessibility, and user experience are covered by standardized metadata blocks (title, description, duration, poster, ratings) and accessibility features (captions, audio descriptions, subtitle tracks) aligned with device capabilities and user preferences.

Architecture and conformance: the specification promotes a client-server model with CDN delivery, cache-friendly segment layouts, and options for low-latency streaming and offline downloads. It provides a conformance test suite and a certification program to verify interoperability among compliant implementations.

Status and governance: VideoonDemandStreamingStandard is maintained by the Video On Demand Standards Consortium (VODSC) with periodic version updates. Adoption varies by market, with several major services indicating alignment and ongoing integration efforts.
