Mô tả Sản phẩm

Bộ Điều Chế DVB-T2 DHP400A is Headend Processor Modulator 

DHP400A DTV head-end processor is the new generation of intelligent headend processing equipment.

This 1-U case comes with 6 independent module slots. Each module can be configured individually based on the applications including encoding, decoding, trans-coding, multiplexing, descrambling and modulating processing and the combination of all these functions.

It supports multiple input and output interfaces and signal formats. With its powerful performance and low cost, DHP400A is especially adequate for the new generation CATV system.

FEATURES

  • Redundancy Power Supply (Optional)

  • Two options for redundancy power supply: Non-Hot Plugging (option 1) Support Hot Plugging (option 2)
