One of the focuses of the CineGrid Amsterdam project is to build “an entry-level 4K” (and beyond) distributed facility. This facility is based on grid and cloud components and specialized cinematic domain specific equipment. These components are connected by optical photonic networks, and can make use of lightpaths to create dedicated circuits providing the required deterministic data transport characteristics (QoS). To support flexible project based modus operandi, the components in the Center of Excellence will be turned into virtualized resources, legoblocks, that can be combined in a dynamic fashion to gather, process, (re)code, annotate, store and stream cinematic data at the required performance level eventually for real time viewing. This architecture has an immediate advantage: the SME’s can concentrate on what they do best: creating content. They just need to define proper creative workflows that use the legoblocks to get their work done.
The challenges come from the intrinsic properties of high-quality digital media, which require large storage facilities and innovative means to read data from disk and transmit to destination over the network. Retrieval and transmission need to happen in a secure way to guarantee data integrity and to fulfil previous agreements between communicating partners regarding the communication model.
The CineGrid Description Language (CDL) coupled with the already existing Network Description Language (NDL), provides a common description of the various network and computing components. The Cinegrid Amsterdam portal leverages the resources described in CLD and acts as a interface between the user(s) and the infrastructure components(storage, computing, visualization). It allows users to create basic workflows that are executed using part of the above-described components.
