Luminato 4X4 dense modulator

The Luminato 4X4 dense modulator with video engine option supports L2TP encapsulation and works as a video engine besides multiplexer and modulator functions that it includes as well.

Comprehensive interoperability

The video engine, together with Teleste video auxiliary core, is a robust solution for operators who know challenges of channelling and managing video services through the DOCSIS CCAP core. The solution allows broadcasting of television services over distributed access (DA) networks while subscribers can keep existing set top boxes. The distributed access networks can be Remote PHY and Remote MACPHY based and built using Teleste’s DA products or other standard-based DA products. The Luminato 4X4 video engine together with the video core relieves DOCSIS CCAP core capacity for the traditional broadband data while robustness and manageability of linear video transmission remains superior, and DOCSIS CCAP core software upgrades or configuration changes do not impact availability of video core and engine resources.

Versatile video engine

The dense modulator with the video engine is fully compatible with the Luminato 4X4 chassis, where it can be fitted into any of the six module slots. In accordance with the Luminato system architecture, the transport stream video processing can be performed in the same module. This enables low-cost applications with a partially equipped chassis while performance can be scaled up by adding modules incrementally. The module supports free-to-air and scrambled services from IP stream sources, which can be adjusted to the operator’s service line-up with the built-in advanced transport stream processing capabilities. The dense modulator with the video engine is compatible with SD, HD and UHD video standards in the MPEG-2, MPEG-4 AVC and HEVC video formats and numerous audio formats.
