DVB-C headend and IP backbone solution for IMCL

电话este Luminato headends have been successfully deployed in India for many years. Ensuring seamless integration of the technology to local conditions and requirements, the deployments are carried out in close collaboration with local partners. The effective deployment of the Luminato platform to IndusInd媒体 & 通信有限公司. (IMCL) was accomplished together with Mehta Infocom, 电话este’s partner in India.

客户需求

The task was to multiplex and encrypt over 450 Digital TV Services and deliver them via QAM Outputs and IP Backbone to more than 20 Remote Headends.

IndusInd媒体 & 通信有限公司. (IMCL), a subsidiary of Hinduja Ventures Limited, is one of India’s largest integrated media companies. The company is a pioneer and one of the largest multi-system operators in the country. 估计有8人.5 million subscribers in 36 major cities, it offers over 450 channels in digital mode. In all IMCL cable television networks, digital transmission is enabled by the IP backbone and digital headends. The system they used so far to fulfil the digital transmission proved to be inflexible and very expensive, since it consisted of devices from different manufacturers and thus was not very reliable. The requirement now was to use a single platform for multiplexing, 加扰, QAM输出和IP输出, all the attributes that the 电话este Luminato system brings together.

解决客户需求

At the heart of this application are the DVB-C modulator modules of the Luminato system, as they are used for 加扰, multiplexing and QAM modulation. The received MPEG-2/4 standard definition as well as high definition SPTS / MPTS IP streams are processed accordingly so that they can be used both as multiplexed encrypted QAM via the DVB-C modulator module (max 24 TS) and as IP MPTS streams via the payload interface to be fed into the networks.

Overall, the following services are processed in the platform:

• 200 satellite services from 6 different satellite positions
• 60 HDTV services with a payload between 8-10 Mbps
• 160 SDTV services with a payload between 2-4 Mbps
• 30 NVOD services with a payload between 2-4 Mbps

All digital services are multiplexed in different QAM multiplexes in the 电话este Luminato platform. A total of 44 QAM muxes are generated to deliver approximately 450 services, Nagravision阿拉丁, Merlin (CLK / DLK) and Conax CAS are used to encrypt channels in the Luminato multiplexer.

The integration of Luminato with all major conditional access systems provides multiple content aggregation options for services from multiple sources, making Luminato the most versatile content protection headend platform in the market.

For maximum operational reliability, a Luminato is equipped with a back-up power supply, which is sufficient for the entire system – an essential difference to the system previously used in IMCL.

好处

With the use of the Luminato system, the following advantages are achieved:

• Multiplexing, Scrambling, QAM Outputs and IP Outputs in a single platform.
• A pure IP-based backbone transmission.
• Smallest form factor – 1U high handling up to 950 Mbps per port.
• 低功耗，最大. 整个机箱功率为120w
• 有竞争力的价格

The Luminato headend platform is known for its high reliability in operation and has delivered its quality promise in this project as well. 除了, the long-term relationship between IMCL, Mehta Infocomm and 电话este has resulted in further large and successful projects by various national and regional MSOs PAN India.
