Time offset optimization in digital broadcasting

Network Time Synchronization Using Clock Offset Optimization

Accurate coverage prediction and optimization - for digital broadcasting

But in order to reach their target subscriber levels before a hypothetical analogue switch-off, digital operators not only face the challenge of making their content attractive, but they also need to know more accurately the quality of terrestrial coverage they can provide to their potential customers. This will help to create a credible service to encourage digital switchover and act as an aid...

Digital Video Broadcasting

The Digital Video Broadcasting (DVB) Project was founded in 1993 by the European Telecommunications Standards Institute (ETSI) with the goal of standardizing digital television services. Its initial standard for satellite delivery of digital television, dubbed DVB-S, used a concatenation of an outer (204,188) byte shortened Reed Solomon code and an inner constraint length 7, variable rate (r ra...

Time-Optimal Digital Geometry Algorithms on Meshes with Multiple Broadcasting

The main contribution of this work is to show that a number of digital geometry problems can be solved elegantly on meshes with multiple broadcasting by using a time-optimal solution to the leftmost one problem as a basic subroutine. Consider a binary image pretiled onto a mesh with multiple broadcasting of size p n p n one pixel per processor. Our rst contribution is to prove an (n 1=6) time l...

Digital Video Broadcasting

DVB-S2 is the second-generation specification for satellite broadcasting – developed by the DVB (Digital Video Broadcasting) Project in 2003. It benefits from more recent developments in channel coding (LDPC codes) combined with a variety of modulation formats (QPSK, 8PSK, 16APSK and 32APSK). When used for interactive applications, such as Internet navigation, it may implement Adaptive Coding &...
