MOTOROLA -- Broadband Communications Sector introduced its SmartStream Encryptor/Modulator (SEM) technology. SEM works with operators’ existing digital networks to quickly and cost-efficiently multiplex, encrypt, and modulate streams for session-based video-on-demand (VOD) services. Designed for interactive digital cable headend architectures, the Motorola SEM has the capability to encrypt a large number of services across eight separate 64 or 256 QAM cable channels into a single rack unit of space. Content delivered via the Motorola SEM is protected by Motorola’s MediaCipher conditional access system, which currently secures content delivered to more than 20 million subscribers.
