Streaming Forum: 2013: 3xScreen Media LiveU Cellular Uplink Case Study
- 1. A Sporting Chance: Cellular Uplink and Sports Coverage Ronen Artman, VP Marketing, LiveU Scott Robinson, Director, 3xScreen Media
- 3. 3xScreen Sports Live Streaming Recent Sports Projects: Live Stream Distribution:
- 4. 3xScreen Sports Live Streaming Workflow Multi-camera OB including replays and graphics Uplink to MCR via LiveU
- 5. 3xScreen Sports Live Streaming Workflow An additional layer of stream-specific production added at our MCR
- 6. Stream-Specific MCR Production • Broadcast bugs • Play pre-event promo clips or slates • Add tickers to welcome and update viewers • Record and loop events at completion • Clip and upload event elements (such as fights) for on-demand viewing • Publish multiple languages from single feed source • Add commentary • Scores, lower thirds and other graphics • Virtual camera effects to single camera shoots so they appear to be shot by multiple cameras • Half and full-time highlights, play in VTs Our centralised MCR production is enabled by LiveU in our workflow
- 7. Staff and equipment efficiencies… • We don't ship our encoders to events – which means: – Higher utilisation of encoding CPU and input ports – Easier logistics – Smaller on-site technical team – Centralised clipping, uploading
- 8. • Prior to the start of the event, early viewers served by MCR vision mixers • OB team free to do their pre-live set ups and tests • Link from event monitored and tuned • At moment of going live, only ever a camera take at MCR • Going-live stress totally removed No pre-live stress
- 9. • Multi-camera production at MCR with cameramen directly connected to LiveU backpacks • No on-site production infrastructure required at venue • Particularly useful when camera operators are mobile or in crowds • Not suitable when frame or audio synchronisation is required MCR Camera Switching
- 10. Cellular Uplink Vs On-Site Encoding • Live streaming decoupled from availability of internet at venue • Use WiFi & Ethernet if available • 3/4G or Ku/Ka broadband satellite via the LiveU backpack if not
- 11. Cellular Uplink Vs On-Site Encoding Ka/Ku satellite complements 3/4G Flexibility
- 12. If Only Using Venue Connections… • Balancing and redundancy across available links • Automatic adjustment to changes in link performance • Less bandwidth required – for one or dual high quality (H264 High profile) links
- 13. • No Line-of-Sight issues • No permits • No security • No parking • No long cable runs in public areas => health and safety issues • No microwave links from production to SNG truck • No SNG truck and engineer => < £££ Cellular Uplink Vs Satellite Uplink
- 14. Non-Live Workflow • Play out edits from timeline instead of rendering • solve FTP issues - assured delivery, stop and restart, finish edit and drive off while uploading or take LiveU out to dinner • Complex distribution of clips from MCR with usual FTP automation
- 15. Thanks Ronen Artman, VP Marketing, LiveU ronen@liveu.tv Scott Robinson, Director, 3xScreenMedia scott.robinson@3xscreen.co.uk
Hinweis der Redaktion
- Focus on the benefits of cellular uplink - or internet contribution, including mobile internet - in the live sports streaming workflow - drawing upon specific projects in the discussionCellular Uplink rather than LiveU per seWe have used LU60, LU70 with/without 4G, LU40, started withLU30, LULite, Xtender
- The sectors we work in are; Agencies & Marketers; Media & Entertainment; Event & Conference Organisers; Corporates; SPORTSWe principally provide event live video production, event live streaming and event live uplinksExample of FA and VANSDistribution – many events on YT and Facebook – plus other live platformsUK newspaper websitesSites of Event Rights Holders
- We do downlink some sports from satellite and live stream it but our general sports live streaming workflow is…Multi-camera OB including replays and graphics – by us or video production partnersUplink to MCR via LiveU
- All our productions are done via our MCRPrior to encoding at our MCR, we add an additional layer of stream-specific production (using Tricasters) – discussed in next slide
- ** Biggest advantage to us of LiveU in our sports live workflow is that enables an MCR-oriented approach **for some events we add customer-specific identity and graphics at the MCR - ie. for example, we have separately added Netherlands football team and England football team graphics at the MCR, sending tailored live streams for The Netherlands and England Football Associations to their respective platformsTWO DISADVANTAGESExtra staff as MCR always manned - but can do multiple events – six events Sunday – 5 of which transited the MCRDouble encoding looses quality - but LiveU link is High Profile and optimised
- Done for football and other events
- Give examples, talk about Sports crowdsBrazil presser and training of England football team the other week – remote control of backpack
- Talk about VANS Spring ClassicGeneral set upFinal day wash out
- Paris Airshow example of link performance changesas we send live contributions to our Master Control Room for all events - this is particularly important as we typically stream multiple HLS and Flash streams (which alone total 8 Mbps as a minimum) and often stream the one event to multiple platforms - YouTube Live, Livestream, UStream, DailyMotion, etc
- Cellular Uplink:Live from anywhereNo hassleLimited planningDisadvantage: Not broadcast TV quality for Sports – Complementary, not a replacement
- Use Euro 2012 exampleQuestions at end..
