So, while you may have to replace your current equipment, I think you're still going to be able to use a splitter on an SDV signal.

[IPTV News] Cable VOD Gateways: With future software releases, Imagine's flexible solution enables additional advanced video services (such as SDV) to be multiplexed through the same QOD Gateway, subject to a 40 Gbps maximum throughput with Imagine's 5RU (rack unit) product (over 14,000 SDTV streams or 3,500 HDTV streams), and a 100 Gbps maximum throughput with its 12RU product (36,000 MPEG-2 SDTV streams or 9,000 HDTV streams). This unprecedented stream count density represents a 4-20 times rack space efficiency improvement factor versus competing solutions.
