We spoke to Sergio Grce, CEO of iSize Technologies (www.isize.co), about the challenges the industry is facing with ever higher resolution content delivery, and his company’s innovative use of AI for pre-processing to deliver higher quality images at lower bitrates – whatever the codec.
In this whitepaper, PHABRIX discusses the use of pseudo-random binary sequences (PRBS – also referred to as pseudo-random bit sequences), along with bit-error rate tests (BERT – also referred to as bit-error ratio tests) to stress test serial digital interfaces. The purpose of any physical layer serial digital interface (PHY) is to transmit or receive data whilst preserving that data’s integrity. In practical systems the major cause of bit-errors is random noise. To stress test such systems, it is necessary to both generate a “noisy” bit stream and then analyze the output from the interface to determine the bit-error rate which represents the integrity of the data.
Scott Griffin – SVP Engineering, M&E, Diversified There are numerous Audio-over-IP formats that have been adopted by the major manufacturers, each with its own strengths and weaknesses when applied to different scenarios. From MADI, Livewire and Cobranet to Dante, Ravenna and AES67, this session looks at real world integrations from recent projects and hear about some of the challenges and advantages.

TV synchronisation will migrate to network-based IEEE-1588 Precision Time Protocol (PTP) and the SMPTE ST 2059 Standard for a network-delivered reference needed for live IP. This presentation from Paul Briscoe (Consultant, Television Consultancy) provides an overview of these standards and how they are applied to media systems, including the virtual generation of legacy signals, how SMPTE ST 2110 systems use PTP natively and how hybrid systems can be designed.

As file sizes continue to grow, managing and delivering large files is becoming an important consideration for organizations of all sizes. Companies have abandoned the commonly used FTP/TCP protocol as a delivery method in favor of alternative file transfer solutions which provide acceleration, reliability, management, and security. Companies seeking file transfer acceleration are not limited to the high-tech sector. Organizations leveraging the benefits of acceleration are found in sectors such as media and entertainment, natural resources, supercomputing, legal, health, government, financial, manufacturing, and more. Companies using TCP-based file transfer protocols to transfer large data sets may experience slow file transfers, or even failed and/or corrupt file transfers. This failure rate can be detrimental to organizations moving large data sets on a regular basis. This wastes valuable time, especially if these transfers take hours across an otherwise healthy network. This white paper will address some of the issues organizations encounter when using TCP-based protocols. It will also outline some other common file sharing methods, and the issues inherent with each. It will then outline the FileCatalyst solutions, and how they overcome the issues surrounding slow file transfers. Finally, this paper will present a number of scenarios that showcase the advantages of...
