Hello df-ga,
Thank you for your question. After almost two full days of research, I
feel that I have exhaustively researched this topic to be able to
present it to you.
You are looking for possible infringers of the "Digital television
with subscriber conference overlay" patent. While products utilizing
this concept were extremely difficult to find, presumably due to the
awareness of the patent, there are some companies that may qualify,
either through current products, or future product/service plans.
Although none of my finds overtly used the concept terms in the patent
(ie. subscriber conference overlay), you will notice phrases like
"simultaneous HDTV video, video conferencing...", "subscriber
demands", "effectively deliver multiple services, such as... streaming
video, video conferencing..." (Tut Systems), "The ability to support
both analog and digital video... to seamlessly integrate Internet
Protocol (IP) telephony and videoconferencing" (Broadcom),
"symmetrical bi-directional data services" (Scientific Atlanta). These
all apply to digital TV/video services.
Without further ado, here are the results of my search. I have also
detailed my search strategy at the bottom of the page.

Scientific-Atlanta's New WebSTAR DPX2100 Cable Modem Designed to Allow
Software Upgrade to DOCSIS 2.0
http://www.sciatl.com/news/02Oct03-1.htm
" The new DOCSIS 2.0 specifications will enable cable modems to
deliver increased upstream throughput from the end user to the
Internet, and, for the first time, give the network operator the
ability to offer symmetrical bi-directional data services. DOCSIS 2.0
can effectively triple upstream data capacity to deliver greatly
improved performance for services such as videoconferencing and
peer-to-peer applications. The new standard also provides the promise
of improved performance in adverse network environments where certain
upstream noise can present a problem for conventional DOCSIS 1.0 and
1.1 technologies.
The WebSTAR DPX2100, which recently received DOCSIS 1.0 certification,
is expected to be available for cable trials by the end of calendar
year 2002, and will be one of the first cable modems to incorporate
the new Broadcom BCM3348 DOCSIS/EuroDOCSIS 2.0 capable cable modem IC.
