Description:
The SmartStream Encryptor Modulator (SEM), Motorola's High Density Encryptor/ Modulator/ Upconverter product family provides cable operators with a cost and space efficient means to perform encryption, modulation and upconversion functions within the digital headend. Providing for up to 8 multiplexes of processing functionality in a single RU pack-age, the SEM significantly lowers the barrier to entry in an on-demand environment. Providing high-speed interfaces to servers and content aggregation systems, the SEM performs multiplex creation, encryption, 64/256QAM modulation and upconversion across the full HFC band. The SEM provides system operators with the necessary tools to launch narrowcast services as the HFC infrastructure evolves to allow subscribers to watch what they want, when they want.
The SEM is ideal for:
- Secure Session Based VOD Applications
- Cost Effective 256QAM Upgrades
- Lower Cost Digital Headend Deployments
Product configurations include:
1) Edge Configuration (On Demand applications) - Digital Baseband Input, encryption, modulation/upconversion
2) Uplink/Central Encryptor - Digital Baseband Input, encryption, high-speed output (no RF)
3) Dense Modulation/Upconversion - Digital Baseband Input, modulation/ upconversion |
