Modulatorul DVB-C DENSE QAM Teleste reprezinta pentru operatorii CATV cea mai compacta solutie Edge QAM, putand furniza intre 12 si 16 iesiri QAM in functie de licentele alese, permitand un total de pana la 72 de canale QAM intr-un singur sasiu Teleste Luminato.
- High-density modulation with 16 QAM channels
- 1200 Mbps payload
- Flexible channel allocation
- Fits any of the six Luminato slots
- 16 independent multiplexers
- DVB CSA content protection
- Support CBR and VBR TS
- Support SPTS and MPTS multiplexing
- PCR processing
- Advanced transport stream processing
- Agile upconversion
The Teleste Luminato equipped with dense QAM modules provides very compact edge QAM platform for Cable TV operators for multiplexing of SPTS and MPTS video services and also PSI/SI table streams. High quality QAM modulation with agile up conversions secures seamless broadcast delivery over HFC network.
The Luminato dense QAM modules sustain selection of 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 Luminato dense QAM module supports Standard Definition, High Definition, UHD and 3D video in CBR and VBR formats and numerous audio formats. Optional content protection is based on DVB simulcrypt standard.
The Luminato dense modulators allow up to 72 QAM channels in one high-performance Luminato chassis. According to the Luminato system architecture, the video processing is performed on the dense QAM modules. This enables low-cost applications even with partially equipped chassis, while having the performance scalability to fully equipped chassis..
Complete cable TV headend in 1 RU
One or more dense QAM modules can be included in 1 RU Luminato platform with Luminato satellite, terrestrial, cable, IP and DVB-ASI receivers, together forming a complete cable TV headend. The flexible architechture enables comprehensive service bouquet with locally received content in the edge of the network.
Embedded content protection
Dense modulator has the optional capability for DVB Common Scrambling Algorithm content protection. The embedded scrambling doesn’t require any additional hardware and the user can freely select which services will be scrambled. Component level scrambling is also supported to allow only video and audio scrambling to avoid descrambling challenges in set-top boxes.
Efficiency and reliability
With the advanced transport stream processing, operators can select the services and components that are relevant to their network, enabling them to efficiently manage the network capacity usage. Thanks to a high degree of automated functions the cost of system set-up and operation is minimised. The automated functions also reduce downtime due to changes in the received services.
