David, the CENC MPEG-2 TS carries concatenated PSSH boxes identical to
the BMFF case.  23001-9 section 5.2.1 says:

5.2.1    General

A CETS PSSH packet carries the complete payload of a `pssh` box, as
defined in ISO/IEC 23001-7. Each packet uses private syntax and carries a
`pssh` box along with an MD5 hash for integrity.
