Signals•Single interface for all. AMWA NMOS IS-08: Audio Channel Mapping•Specification includes:-Channel mapping -Selecting of individual channels within a stream-Shuffling of signals within the stream•Example 5.1 Speaker Monitoring System-Easiest method is 6 single channel streams§Not Efficient-1 Stream / 6 Channels§Sent entire stream to each speaker and speaker knows which channel of the stream to extract TR-1001: Taking everything into account JT-NM TR-1001: Configuration and Security„Plug ‘ n‘ play workflow"The Goal:•How can I connect two devices that have not been preconfigured without typing one single IP address?•Yet still keep the network secure! BCP-003 AMWA NMOS IS-07: Event and Tally Specification•IS-07 Provides a mechanism by which to emit and consume ‘states’ and ‘state changes’-Vision mixer selects a Camera for on-air-Ta l l y-GPIO over IP•Lets look at EVENTS AMWA NMOS IS-07: Event and Tally Specification•AMWA NMOS IS-04 v1.3•New source element event_type-Boolean: On or OffButton, Tally signal,-String: UMD Label, Description, Color value (Hex)-Number: Temperature, Gain, Encoder value, Metering value-Enum: One state of a collection of states, simple list of possibilities•IS-04 Senders can now send states of events•Similarly visible in NMOS Explorer just like Audio or Video Senders/Receivers AMWA NMOS IS-07: Example AMWA NMOS IS-07: Example•Leveraging IS-04 v1.3-Lever Key State Down-Lever Key State UP-Rotary Encoder•Expose these via IS-04•Connect via IS-05-3rdparty Control systems-Can connect to multiple systems as each element is exposed as its own entity JT-NM Tested Program•TwoPrograms-SMPTE ST 2110-NMOS/TR-1001•ResultsPostedSeptember 2019-Hosted@ Riedel Wuppertal Germany Riedel & NMOS Status IntercomNMOSStatusof StandardMicroN IPARTIST AES67-108ARTIST-1024RSP-1232-HLBoleroIS-04Discovery and RegistrationStableMN 5.0In progressDirector8.0Version 1.0WithAudio Monitor AppNot implementedIS-05Connection ManagementStableMN 5.0In progressDirecotr8.0Version 1.0With Audio Monitor AppNot implementedIS-08Audio Channel MappingPublicUnder ReviewIn progressDirecotr8.0Version 1.0With Audio Monitor AppprototypingIS-06Network ControlPublicNot RequiredNot requiredNot requiredNot requiredNot requiredIS-07Event & TallyPrototypeWatchingideasideasConceptideas29 Thank YouRick Seegull, Riedel Communications Inc.rick.seegull@riedel.net+1-805-404-8036
