Media and descriptive metadata from 24 HD-SDI ingest ports are streamed continuously from the A&P sites to the News sites using “while scenarios,” which produce a delay of only 10 to 15 seconds from the moment the first image comes in as an HD-SDI signal until it is available to journalists. Notably, different creative and technical teams across the facility receive the same high-quality, English-language descriptions of media materials, allowing for timely decision-making. The A&P site also gathers and processes all the media coming as FTP/Internet transfers or from ENG crews. In addition, the common production platform allows users of different sites to search, browse and pull content from the neighboring sites, all via lightweight Web sessions.
Graphics and visuals
RT also wanted to centralize and maximally expedite its graphics creation process. Following an extensive elements analysis, most of the graphics were designed as templated scenes within the Vizrt environment, to be easily used by journalists and editors. This high level of integration allows several advantages in terms of quality of output, transparency and workflow efficiency. Journalists do not need to switch between different systems, and anyone can review the graphics and text at any point of time, including during review from the rundown, greatly reducing probability of errors.
For recurring visuals such as tickers and weather maps, automated data sources were introduced, minimizing the need for manual preparation. Production of more complex graphics is also fast-tracked, via playing a completed sequence as an SDI signal and recording it on the Telestream Pipeline appliance. This workflow allows graphical scenes with transitional logic inside the fastest way to Dalet sites and Avid post-production, and multiformat delivery of media for Internet publishing.
Twenty Adobe and Apple NLEs were consolidated into a common pool; each station was enabled to search and browse media databases at all four Dalet sites and to be flexibly allocated based on specific current needs. All stations also use an edit-in-place approach without the need of additional file transfers, saving a lot of time and storage resources.
One of the most challenging aspects of the project was development of an enormous HD-SDI infrastructure. Six studios, multichannel playout, its own teleport, centralized ingest — all located across three separate buildings — made the task incredibly complex. Riedel’s optical multiplex system was chosen for the distribution of a large volume of HD-SDI signals, AES/EBU streams, intercom and control signals. Approximately 56 MediorNet frames, more than had ever been used in Europe in a single location, were installed throughout the facility, creating a highly efficient multiservice optical network.
