  2. What is OCA? • Control and monitoring architecture for networked media devices • "Media" = audio & video • OCA is not • A media transport standard • A device programming model • A system controller programming model • A user interface generation architecture • Target • Professional applications • Networks of all sizes, tiny (2 nodes) to huge (10k nodes) • Work with many/most media transport architectures • Mission-critical applications • Goal • Open public standard • Honored Ancestor • AES-24 rev 22

  3. What is the OCA Alliance? • Unincorporated alliance of nine companies • Bosch Communications Systems • d&b audiotechnik • Duran Audio • LOUD Technologies Inc • Media Technology Systems • PreSonus • Salzbrenner Stagetec Mediagroup • TC Group • Yamaha Corporation • plus 52 Observer members • Purpose: Make OCA an open public control standard. • Plan • Phase 1 • Produce draft 1.0 of OCA Specification by end of April 2012 • Work with a public standards organization for formal standardization • Phase 2 • Incorporate as a trade association • Support evolution of the standard • Promote adoption of the standard • Expand membership rev 23

  4. Alliance: Status • Technical • Draft 1.0 OCA specification Complete ~May 15 (2 weeks late) • Reference implementation Available in Q4 from Bosch Discounted price to members • Management • Incorporation Expected complete June 14 • Future membership 8 of 9 founding members (including all the large ones) have committed; expecting 9th as well • Standards Development Organization Not selected yet • Position • Trade profile Established & growing • Other comparable open efforts None known rev 24

  5. Alliance: Near Future Plans • Update and Augment OCA technical specifications. • Begin OCA 2.0 specification work. • Primary addition: VIDEO • Begin work on recommended practices to support the standard. • First: Recommended OCA API • Enhance public programs. • Public relations • Design program • Tradeshow presence, initially via members' booths • Education & training • Produce OCA Overview white paper - 10-15 pages • Launch OCA developer tools discount program for members. • First examples, available 2012 Q4 • Bosch OCA reference implementation - discount for full members • Bosch OCA conformance test tool - free to all members • Create liaison relationships with other trade associations. rev 25

  6. OCA: Features • Flexible • Expandable, evolvable • Upwards-compatible • Friendly to proprietary extension (aka "laterally compatible") • Multiple protocol platforms • Functional • Full discovery and enumeration feature set • Full multiple controller support • Supports control grouping - submastering, ganging, etc • Supports parameter storage - presets, scenes, snapshots, etc. • Supports multiple simultaneous control and media transport networks • Robust • Fully acknowledged • Security option (uses TLS in TCP/IP protocol version) • Efficient • Compact binary protocol data formats (in most protocol versions) rev 26

  7. OCA: Parts • Framework (OCF) Architectural concepts and mechanisms. • Device model • Functional mechanisms • Class Tree (OCC)Object-oriented definition of control & monitoring functional repertoire. • Manager Classes Device housekeeping & global functions • Worker Classes Signal processors & monitors • Agent Classes Control & monitoring modifiers/aggregators • Protocol Implementations (OCP.1 ... OCP.n)OCA will be a family of protocols for different contexts. • OCP.1 : for TCP/IP networks • OCP.2-n : TBD, may include USB, XML, ... rev 27

  8. Steps Forward • The Alliance is seeking a standards development partner organization. • Goal: Make OCA an open public standard or standards suite. • The standard will have no proprietary technical content. • Multiple versions of the standard will need to be published. • Alliance version 1.0 draft specification ready (nearly) now • Alliance version 2.0 draft specification targeted ~ 2013 Q4. • The Alliance will actively support the standardization effort. • V1.0 documents • Current drafts are readable and complete, but not in standards format or language. • The Alliance is prepared to provide writers to (help) render the documents into the appropriate form. • The hope is for a relatively expeditious process. rev 29
