[Work In Progress] AMWA BCP-004-02: NMOS Sender Capabilities

What does it do?

• Allows an IS-04 Sender to express parametric constraints on the types of streams that it is capable of producing

Why does it matter?

• Controllers need to know whether a Receiver is capable of handling the streams a Sender is capable of producing before connecting the two
• Controllers need to know whether a Sender is capable of handling specific stream parameters before applying IS-11 active constraints

How does it work?

• Establishes an open Capabilities register in the NMOS Parameter Registers that lists specifications for parametric constraints (such as width, height, frame rate, number of channels, etc.)
• Defines how a Sender instantiates these Parameter Constraints to make up a list of acceptable Constraint Sets, within the IS-04 caps attribute
