17 DELIVERY TO PBS, 2014 Producer Station PBS

18 PRODUCER BENEFITS Lowered captioning cost Higher captioning quality Faster delivery Weather a non-factor HDCAM decks not needed Exports are faster than real-time

19 PRODUCER CONSIDERATIONS Simple change means re-export, not insert Tape still easier to view Qualitative debate Workflows do change

21 Where we came from

22 Where we came from and still are.

23 Final programs are transferred from file to tape

24 Final programs are transferred from file to tape FedEx delivery to PBS

25 Final programs are transferred from file to tape FedEx delivery to PBS When critical, hand deliver as a backup (put someone on a plane)

26 File delivery to PBS

27 Some reluctance to implement File delivery to PBS

28 File delivery to PBS Some reluctance to implement Established workflows were in place It s not broken

29 File delivery to PBS Some reluctance to implement Established workflows were in place It s not broken Signiant was installed and tested for delivery to PBS

30 File delivery to PBS Some reluctance to implement Established workflows were in place It s not broken Signiant was installed and tested for delivery to PBS Aspera also available, and used as an alternate transmission path

31 First Steps

32 First Steps Sneaker Net delivery to Signiant server File placed on drive, loaded into Signiant for delivery MAC drive not compatible with MS Server 2008? Worked with PBS in testing compatibility

33 First Steps Sneaker Net delivery to Signiant server File placed on drive, loaded into Signiant for delivery MAC drive not compatible with MS Server 2008? Worked with PBS in testing compatibility Initial transfer was 60 GB file, USB2 or Firewire would be slow

34 Implementation

35 Implementation Frontline workflow to transfer files to PBS Dell R510 server running Windows Server 2008 with a RAID disk set for media. One Ethernet port is connected to the OC-3 switch to PBS. The other is on the subnet for Frontline. The OC3 circuit is bandwidth limited to prevent data loss of the World video feed.

36 Implementation Concern over other workflows, NOVA, AMEX, etc.

37 Implementation Concern over other workflows, NOVA, AMEX, etc. Create SAN space allocated for PBS delivery, watch folder

38 Implementation Concern over other workflows, NOVA, AMEX, etc. Create SAN space allocated for PBS delivery, watch folder Send test file, process and QC eval at PBS

39 Pass PBS Virus Check PBS Receipt of File

40 Pass PBS Virus Check Move from PBS DMZ to MOC SAN PBS Receipt of File

41 Pass PBS Virus Check Move from PBS DMZ to MOC SAN Baton Tech Evaluation PBS Receipt of File

42 Pass PBS Virus Check Move from PBS DMZ to MOC SAN Baton Tech Evaluation Explode into OP, transfer to Avid PBS Receipt of File

43 Timing File placed into WGBH Signiant folder at 14:50 File arrived at PBS DMZ at 17:38 File checked into MOC Avid at 21:32 Transfer time: 6 hours, 48 minutes receipt notifications to WGBH

44 Issues Failed transfer, file shows as transferred but file size not correct

45 Issues Failed transfer, file shows as transferred but file size not correct Transfer was started before file was completely loaded into watch folder

46 Issues Failed transfer, file shows as transferred but file size not correct Transfer was started before file was completely loaded into watch folder Adjusted media watch check time from 1 min to 5 minutes Allowed file to finish loading before transfer

47 WHAT S NEXT More comprehensive roll-out for entire station Buy-in OP1a Export Training and protocols Faster, more automated workflows International and Textless versioning Looking ahead

48 CHALLENGES AND WISH LISTS Higher quality codec in OP1a Better captioning tools Straight from Avid to PBS Optical disks that can play larger file 4K Better distribution system
