High Bandwidth Interface for Cameras and Digital Cinema Fraunhofer IIS (S. Foessel, A. Widera) 22th Feb 2006 Cover Slide 1

 Actual situation Today's and future digital cameras need higher interface bandwidth ≥ 10 Gbit/s High bandwidth interface between cinema server and projector is one possible solution according DCI spec. With more and more 2k and 4k DI processes postproduction needs also a higher bandwidth interface Overview slide

 Application fields Overview slide

Overview slide

 Proposal Proposal of a 10 GE interface with real-time features, but also with the option to use as a standard interface Real-time requirements but also compatibility to IT infrastructure desirable, because of the price and availability Overview slide For some applications a robust connector is needed, but not for all (harsh environment and IT environments!)

 Concept – Protocol Application layer Data Transport layer UDP header Network layer IP header UDP header Data Overview slide Network interface Ethernet header IP header UDP header Data Physical network

 Concept - Overview 10GE standard XFP modules (physical layer) 10GE standard ethernet clocking and framing allows use of 10GE infrastructure (e.g. switches) Dedicated links between one data source and one or more destinations guarantees real-time work UDP/IP protocol allows easy integration in workstations Topologies: point-to-point or point-to-multipoint Note: The IF is not intended as a general purpose 10GE network with all possible protocols! Overview slide

 Concept – Protocol Framing Overview slide

 Concept Use of Ethernet Jumbo Frames up to 9000 Bytes 64/66 Bit encoding / CRC-32 / optional FEC Payload within a frame can be Image Data, compressed or uncompressed (e.g. one line of an image per Ethernet frame, or one component of a line) Audio Data, compressed or uncompressed Metadata Data Control Data Overview slide

 Time schedule Realization of a complete 10GE link demonstrator and technology study within the next 8 months Use of the Fraunhofer developments ARRI D20 and megacine field recorder as example Involvement of the ASC into the requirement definitions and tests (Cooperation is officially defined) Overview slide
