DVTproppar
DVTproppar is a term used in digital video technology to denote a structured collection of property parameters that describe how a digital video transport system handles and conveys video data. It typically appears as a named block within a DVT metadata schema to support interoperability between equipment and software.
The term combines DVT, shorthand for digital video transport, with proppar, a contraction of property parameter.
Key components commonly described within a DVTproppar block include:
- chroma_subsampling and dynamic_range
- transport_metadata such as clock_reference, packetization_mode, and buffering_policy
Interoperability and standards: there is no universal standard for DVTproppar across all vendors, so deployments vary.
Example: a representative DVTproppar block might specify color_space=BT.709, bit_depth=10, resolution=1920x1080, frame_rate=30, aspect_ratio=16:9, chroma_subsampling=4:2:2, dynamic_range=SDR, timecode=00:00:00:00,
