Term	Meaning
Frame	One complete TSMP texture update. It contains a header and optional payload.
Header	The fixed 56-byte metadata block at the start of a frame.
Payload	The data body after the header. It contains network messages.
Codec	The component that turns bytes into pixels and pixels back into bytes.
Luma4	The default TSMP codec used by the sample prefab.
Network ID	The ID used to route a message to a matching TSMPNetworkBehaviour.
Binding	Generated setup data that maps a network ID and field hash to a component field.
Variable state	A payload message containing one or more synchronized field values.
TSMP RPC	A payload message that dispatches a method-like event through the texture stream.
Frame index	The sender's increasing frame number. It helps detect duplicates and loss.
CRC	A checksum used to reject damaged headers.
Payload capacity	The number of payload bytes the current texture and codec can carry.
Receive interpolation	Per-component setting that decides how received values are applied.
Transport	The path carrying the encoded texture, such as VRChat camera output, Spout, or OBS.

Payload buffer is full	Selected synchronized data does not fit in the current frame.
Header CRC mismatch	The transport changed header pixels or the receiver is reading the wrong region.
