Media Capabilities. FLAME provides a set of media capabilities as a part of the project offering. These media capabilities will be available for experimenters and particularly for the entities that participate in the project as result of the open calls. These capabilities are provided in FLAME by means of Foundation Media Services, which offer an initial set of basic functionalities useful for a variety of media implementations, such as storage capacity and adaptive streaming. In this way, the Foundation Media Services can be seen as packetized media components. FLAME has defined a list of Foundation Media Services, which will be implemented along the project work plan. Some of these Foundation Media Services has been selected to take advantage of the key FLAME benefits, based on the project technical approach, such as reduced latency or secure content access, as described in Section 7.2. The Foundation Media Services that will be ready for the 3rd parties involved in the project after the first open call are depicted in the table. Name Description Metadata database This component consists in a generic database to store metadata, which is a required module in most of media services. Some complex media services require the stateful replication of a synchronised database. For example, a certain service may require a replicated metadata database in the edge to improve the availability of media contents. FLAME benefits and technological innovations enable an efficient procedure for the replication of databases. Content ingest and storage This component enables the insertion of assets to be delivered in media services. By means of a REST API, assets can be uploaded, deleted and downloaded. The component includes a local database to keep some data about the stored contents. The FLAME platform capabilities enable a smart replication of this component for a better service performance. Name Description Media quality analysis This component provides information about a certain media asset, including technical information (codec, duration, framerate, resolution, bitrate) and also an estimation of its visual quality. Transcoding and transrating and content conditioning Transcoding consists in the change of the video or audio specification to represent the content of an asset (source encoding). Transrating is a similar process but in this case the encoding specification does not change. Transcoding and transrating typically aim to reduce the bitrate of an asset (this processing will cause...
Media Capabilities. The CMS shall include Modules to make it easy to deliver rich-media material on County Web Sites. This includes capability to view, stream and provide download options of videos, slideshows and photo albums through the CMS’s Photo Manager/Slideshow and Media Manager Modules.
Media Capabilities. Arguably one of the most influential contributions to current scholarship on media selection is Media Synchronicity Theory (Xxxxxx et al. 1999). Media Synchronicity Theory suggests that communication can be encapsulated in two key processes: conveyance and convergence. In addition, Xxxxxx suggests that media are best analyzed based on communication capabilities, and Media Synchronicity Theory provides a concise summary of the theoretical foundation for each. These capabilities (feedback, symbol variety, parallelism, rehearsability, and reprocessability) can be matched with the communication processes of conveyance or convergence to optimize communication depending on the level of equivocality associated with the task being performed (Xxxxxx et al. 1999). Media Synchronicity Theory provides a much needed foundation for categorizing media beyond physical properties. Instead the media capabilities framework provides a high level view of media affordances that transcends specific technologies. This framework for categorizing capabilities will be employed and expanded in the current research. In addition to the capabilities proposed by Xxxxxx, this research will explore an additional capability afforded by communications media: discretion. Appropriation Factors Adaptive Structuration Theory provides the most comprehensive theoretical lens for framing the interplay between technology and social structures. It posits that technology
Media Capabilities. There have been a number of efforts to examine the communication capabilities introduced by information and communication technologies. Arguably one of the most influential contributions to current scholarship on media selection is Media Synchronicity Theory (Xxxxxx et al. 1999). Media synchronicity theory suggests that communication can be encapsulated in two key processes: conveyance and convergence. In addition, Xxxxxx suggests that media are best analyzed based on communication capabilities, and Media Synchronicity Theory provides a concise summary of the theoretical foundation for each. These capabilities (feedback, symbol variety, parallelism, rehearsability, and reprocessability) can be matched with the communication processes of conveyance or convergence to optimize communication depending on the level of equivocality associated with the task being performed (Xxxxxx et al. 1999). Media Synchronicity Theory provides a much needed foundation for categorizing media beyond physical properties. Other frameworks have been suggested, but Media Synchronicity provides a parsimonious model. This framework for categorizing capabilities will be employed and expanded in the current research. In addition to the capabilities proposed by Xxxxxx, this research will explore an additional capability afforded by communications media: discretion. Privacy and Disclosure In part, Media Synchronicity Theory is based on the Xxxxxxx Xxxxxx Theory that outlines the fundamental basis for communication systems. Dennis’s communication capabilities--velocity, parallelism, symbol sets, rehearsability, reprocessability--are drawn from Xxxxxxx and Xxxxxx’x concepts of channel capacity, frequencies, symbol types, encoding, and decoding respectively (Xxxxxx 2008) (Xxxxxxx et al. 1949). In a follow-up to his seminal Communication Theory, Xxxxxxx introduced his Communication Theory of Secrecy Systems (Xxxxxxx 1949), which provided a conceptual framework for “secrecy systems” to conceal messages and ensure privacy. Although focused on providing a theoretical foundation for cryptography, this early work highlighted the importance of scholarship related to information privacy and communication security. Decades later, research on privacy and information security spans multiple disciplines including computer science, economics, information systems, and public policy, among others. Concern for controlling the flow of information between parties with potentially different priorities, values,...
