Scientific-Atlanta entered the video-on-demand transport fray this week with the unveiling of a new sub-system for its Prisma IP platform.

Touting flexibility, S-A's new VOD transport cards support legacy ASI and SDI stream formats as well as Gigabit Ethernet, the transport technology of choice for most new VOD deployments. S-A said the flexibility will also come into play as operators widen their libraries of on-demand content and move to centralize their VOD servers and architectures.

S-A also joins a very competitive market of VOD transport players, including Internet Photonics, Artel Video Systems and Harmonic Inc., among others.
