The SEM is ideal for secure session-based VOD applications, 256 QAM upgrades, digital headend deployments, on-demand applications, switched digital video, encryption, and modulation/up-conversion. The SEM-V12 gives system operators the necessary tools to launch narrowcast services as the HFC infrastructure evolves to allow subscribers to watch what they want, when they want. With high-speed interfaces to servers and content aggregation systems, the SEM-V12 performs multiplex creation, encryption, 64/256 QAM modulation, and upconversion across the full HFC band. Providing up to 16 multiplexes of processing functionality (up to 12 QAM outputs) in a single-RU package, the SEM-V12 significantly lowers the barrier to entry in an on-demand environment. The SmartStream Encryptor Modulator (SEM), Motorola’s family of encryptor/modulator/upconverter products, provides cable operators with a cost- and space-efficient means to perform encryption, modulation, and up-conversion functions within the digital headend.
