A good analogy would be PC's vs. Macs. Two different platforms, different CPU instruction sets, therefore different guides/operating systems and a different encryption scheme.
Motorola based Headends talk to the box via the ALOHA protocol for authorizing services, VOD, 2-way, etc.. and use the Motorola MediaCipher encryption scheme. Some guide software that runs on Motorola/Broadcom based CPU's are I-Guide, PassportDCT, Microsoft Guide, and Verizon IMG.
Scientific Atlanta based Headends talk to the box via the DAVIC protocol for authorizing services, VOD, 2-way, etc.. and use the SA PowerKEY encryption scheme. Some guide software that runs the Scientific Atlanta PowerTV platform are SARA, Passport, Time Warner Navigator.
Scientific Atlanta software is more mature and robust. For example that platform has the ability to do Caller ID on screen, high color games, guide animations, transparencies and fade effects. Motorola software has been very utilitarian until the Verizon Fios IMG guide. Hopefully developers will fix the limitations of the Motorola platform in the future with some creative programming.
