AIMS IP Showcase IBC 2019 September 2019 Curated by Video Services Forum vsf.tv 2 IP SHOWCASE THEATRE AT IBC2019 : 13 -17 SEPT 2019 Goals of this Talk 1. How does the 2110 -40 ancillary data standard work? 2. Understand how live captioning in 2110 -40 is (and isn’t) different from SDI 3. What improvements does 2110 -40 present for ancillary data chains? 4. What do I need to understand to implement live captioning as part of a facility wide IP transition? 5. What is the status of industry adoption on 2110 -40? IP SHOWCASE THEATRE AT IBC2019 : 13 -17 SEPT 2019 CURATED BY 2110 Media Flows ✔ Video, audio, and data are three separate RTP multicasts ✔ Streams are synchronized with PTP timestamps in each packet VIDEO ( -20) AUDIO ( -30) ANC ( -40) PTP AIMS IP Showcase IBC 2019 September 2019 Curated by Video Services Forum vsf.tv 3 IP SHOWCASE THEATRE AT IBC2019 : 13 -17 SEPT 2019 CURATED BY Ancillary Data in 2110 -40 RTP Header including PTP -derived timestamp Zero or more SMPTE 291 VANC packets associated with one field of video 2110 -40 Header Information RTP Packet – at least one is sent for each field of video VIDEO ( -20) AUDIO ( -30) ANC (-40) PTP IP SHOWCASE THEATRE AT IBC2019 : 13 -17 SEPT 2019 CURATED BY Ancillary Data in 2110 -40 Live subtitling still carried in same "Inner" formats as in SDI VANC • USA/NTSC: SMPTE 334 VANC packet, CEA -708 payload • EU/UK/PAL: OP -47 VANC packet, Teletext payload • Japan/Brazil/ARIB: ARIB B37 VANC packet, or SMPTE 334 Conversion between SDI and IP is simple and does not require generic gateways to have deep subtitle format knowledge.
