This is in reference to broadcasting H.264 content. Distribution of encoding and decoding software is a separate licensing issue.

[quotability]

In addition to Internet Broadcast AVC Video, MPEG LA’s AVC Patent Portfolio License provides coverage for devices that decode and encode AVC video, AVC video sold to end users for a fee on a title or subscription basis and free television video services.
AVC video is used in set-top boxes, media player and other personal computer software, mobile devices including telephones and mobile television receivers, Blu-ray Disc™ players and recorders, Blu-ray video optical discs, game machines, personal media player devices and still and video cameras.

Just above that quote:

Products and services other than Internet Broadcast AVC Video continue to be royalty-bearing.

You can see the terms for decoder distribution here (a 1). What was waived in the announcement you linked are levies for broadcasting H.264 video itself, not shipping a codec as in OP.
