Digital TV Demodulation

Ensigma Broadcast IP

High-performance IP cores for digital television reception

Ensigma Digital TV demodulation IP platform provides a generic architecture that supports multiple TV standards. Proven and efficient unique hardware architecture combines multiple programmable processing engines, along with hardware accelerators for common high-throughput operations such as error correction and filtering. Solutions are available in a wide range of performance capabilities, from single-standard to multi-standard implementations.

Features
  • Multi-standard support on a single platform
  • DVB-S2X support
  • Highly competitive performance
  • NorDig/DTG compliant where applicable
  • Provides physical layer demodulation: interfaces to a tuner and produces a MPEG transport stream
  • Hardware accelerators and special purpose processes provide a flexible architecture with optimal low-power clock speed
  • Supports locally-controlled or host-controlled tuners
Benefits
  • Complete TV front-end solution
  • Silicon proven design
  • Low-power consumption
  • Easy integration into an SoC
