| Abstract | As the digital cable TV broadcasting technique is developed, various applications on a digital cable receiver have been required. Particularly, $OpenCable^{TM}$ specifications for digital cable TV broadcasting have presented a cable receiver with multi-tuner for serving a Digital Video Recorder (DVR) application, a Picture-In-Picture (PIP) application, a Picture-Out-Picture (POP) application and etc. But there are some problems for supporting such applications because the existing $CableCARD^{TM}$ device processes conditional access for only one channel at once. Therefore $OpenCable^{TM}$ specifications have introduced the Multi-Stream $CableCARD^{TM}$ device in order to solve the above problems. The Multi-Stream $CableCARD^{TM}$ device can support conditional access processing for 2 or more channels simultaneously. In this paper, we have designed hardware architecture of the Multi-Stream $CableCARD^{TM}$ device. The designed Multi-Stream $CableCARD^{TM}$ device is implemented based on a FPGA which processes multi-channel filtering, MPEG-2 TS filtering, and DVB-Common descrambling and a microprocessor which manages conditional access applications. Especially we have proposed a descrambler design for the high-speed processing in order to support the 200 Mbps input data bandwidth. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
