MultimediaVideo

MultimediaVideo is a holistic concept describing a multimedia video content format and delivery framework that unifies video, audio, text tracks, and metadata into a single packaging and streaming workflow. It supports synchronized playback, accessibility features, and dynamic content.

It relies on a container that can house video and audio streams, subtitles, captions, and metadata, often using existing container standards like MP4/ISOBMFF or CMAF. It supports multiple codecs and adaptive bitrate.

Encoding and packaging involve encoding video and audio with codecs like AVC/HEVC for video and AAC/Opus for audio, plus text tracks and metadata. Packaging for streaming uses segmented formats and manifest files (e.g., DASH or HLS) and subtitles in WebVTT.

Delivery and playback: Delivery via progressive download or adaptive streaming; client players select appropriate streams based on bandwidth; supports DRM where applicable.

Applications and use cases include video-on-demand, live events, e-learning, broadcast contributions, and digital signage.

Standards and interoperability: Not a formal standard; relies on established standards; interoperability depends on chosen encoding, packaging, and DRM. Some vendors market the term to describe their integrated solution.

Development and future: Ongoing evolution with higher resolutions, immersive audio, object-based media, and better accessibility; emphasis on low-latency streaming and metadata interoperability.
