OFDM for Digital TV Terrestrial Broadcasting
This paper treats the problem of digital TV terrestrial broadcasting in presence of co-channel interference from analogue TV services. The channel capacity is calculated for the optimum distribution of the transmitted power. An OFDM scheme is presented which is designed to be robust to the analogue TV interference. Power and number of bits per symbol are assigned to each OFDM channel to give th...
متن کاملDigital Coding of High Quality TV
The study and development of systems for higher quality television has seen tremendous growth in recent years. This has been motivated by the fact that existing television systems give inadequate picture quality, especially for viewing on large screen displays. The main impairments which have been identified an~ scanning artifacts (line stucture visibility and flicker), limited resolution, and ...
متن کاملSecure Communication in Digital TV Broadcasting
To provide subscription-based Digital TV (DTV) data, services providers scramble the data stream (program content) with some secure measures such as ECM and EMM via using control words, and send the stream to conditional access system (CAS) in the set-top box (STB). Smart card is used to decrypt the control words and accordingly to enable the STB to descramble the scrambled signal. Therefore, s...

متن کاملIntegrating Semantic Technologies with Interactive Digital TV
Interactive digital TV is becoming a reality throughout the globe. The most essential aspect of TV broadcasting is enhancing the interacting experience for the viewer. To this end, we explore the potential of introducing semantics in the distribution, processing and usage of the media content. We propose a smart iTV receiver framework capable of collecting, extending and processing semantic met...
