  5. SYSTEM CONTROL

  6. Why another control standard? • OCA is the only control architecture that is all of the following: • Pro application oriented • Scalable up to huge network sizes • Suitable for mission-critical applications • Compatible with proprietary product features • Futureproof • Secure • On track to become an open public standard.

  7. OCA In Action: Concert tour Concert tour sound system • Touring system, possibly incorporating equipment from prime contractor and various subcontractors. • Multiple ad-hoc connections, varying from place to place, ideally using network audio. For example: • Prime contractor provides main loudspeakers, subcontractors provide delay systems, fills, woofers, etc. • Connected to resident venue system for area fill. • Connected to show video systems, radio, TV,& internet broadcast systems, recording systems, & press. • System configured modularly, with multiple mix and loudspeaker/ amplifier subystems, variously deployed from rental house(s) for different tours. • Media transport may be mix of Ethernet, AES3, MADI, AVB, Dante, etc. OCA Benefits Central wired & wireless control of multiple network(s).Multivendor support. High reliability. Media flexibility.

  8. OCA In Action: Large Install Venue Large installed sound system • Example: stadium, multipurpose arena, large auditorium • Multiple program sources, control stations, loudspeaker clusters, and external interfaces. • Interfaces to paging, signage, security, emergency (fire), show video, security, and other internal systems. • Interfaces to external systems - broadcast, internet, user devices (tablet, smartphone). • Evacuation standards compliance may be required. • Security may be required. • Network infrastructures are typically administered by central IT. • Large to very large network diameters. OCA Benefits Control of large & complex networks. Security. Public standards compliance for Evac. Multivendor systems.

  9. OCA In Action: Broadcast Intercom Network Broadcast Intercom System • Example: major television network production intercom • Thousands of intercom stations, multiple control points. • Transcontinental networks using private leased data lines. • Interfaces to broadcast mixing equipment. • VoIP interfaces • Portable and fixed-location stations. • Many subnets - multiple sites, multiple work environments within buildings, multiple remote locations. • Network infrastructures may be administered by production intercom departments or by central IT. • Frequent reconfiguration. • Critical function - must not fail (millions of dollars at stake) OCA Benefits High reliability. Much simplified cabling. Ability to usecorporate network(s). Multivendor systems.

  10. OCA In Action: Bar Band Tiny Sound System for Small Music Acts • Single media network connecting everything • Four house speakers, two stage monitors, mixers, mics, ancillary gear • In-ear monitoring system optional • Powered loudspeakers, network-connected • One main house mixer, tablet-based (no big mixing desk) • Onstage monitor mixers for each musician - small tablets on mic stands • Wired microphones connect through stage box on network • Wireless microphones connect through receiver(s) on network • In-ear monitors connect through transmitter(s) on network • Wireless access to main house mix is an option • Optional external interfaces, both analog and digital, to house systems • Optional multitrack digital recorder on network • Optional webcasting interface on network and on internet OCA Benefits Much simplified cabling. Improved diagnostic functions/features. Easy reconfiguration.

  11. A Peek Under the Hood

  12. OCA Device Model Box of Objects

  13. OCA Control Repertoire (v.1.2) • Gain controls • Mutes • Switches (n-position) • Delays • Equalizers • Filters (IIR & FIR) • Limiters & Compressors • Expanders & Gates • Levelers • Matrices • Signal generators • Arbitrary numeric parameters • Level sensors (meters) • Frequency sensors • Time interval sensors • Temperature sensors • Grouping (~VCA groups) • Crossfading • Media connections & routing • Proprietary extensions

  14. OCA Network Traffic Includesmeter updates

  19. Benefits of OCA • Interoperability • Third party manufacturers can add value to your systems. • You can sell into other systems you did not originally supply. • OCA is open and freely available. • Royalty-free • Alliance membership NOT required. • Specific software development kit NOT required. • Reduced time to market and engineering cost. • OCA is an already engineered and proven architecture. • As OCA is adopted, a helpful OCA ecosystem will arise. • Some big customers require compliance with public standards. • Self-certification program → No added costs for 3d-party testing.

  20. Benefits of Alliance Membership • Participation in evolution, definition and promotion of OCA • Education from meeting with other manufacturers • Early knowledge of future changes and directions • Joint marketing, e.g. at Infocomm • Discounts on selected software, e.g. reference designs • Free OCA compliancy self-test software
