What it holds

Identifies how the object is encoded: byte order, explicit or implicit VR, and pixel data compression.

In migrations and validation

Source and target often disagree on which compressed transfer syntaxes they accept. Negotiate or transcode losslessly; never let a migration silently convert lossless data to lossy. See the transfer syntax reference.
