1 Interoperability and File-based production for HDTV How far away is 80p/50,60 from mainstream production? IBC Amsterdam, 11 September Dr Hans Hoffmann Programme Manager

2 Overview 1. Challenges due to HDTV 2. File based production: the interoperability questions 3. Status 80p/50 in production 4. EBU activities

3 Why file based? Reduce costs Produce more programme for multiple platforms Flexible workflow adaptation to new businesses Avoid special designed solutions Collaboration location independent Utilize solutions from IT

7 Review the interoperability questions Which File Format? Exchange Files If MXF, which Operation Pattern? FTP it to me Which compression format? Which Metadata? Protocols, network, management?

8 The interoperability-performance questions How many real-time HD-SDI I/Os Exchange Files FTP it to me Which GUARANTEED file transfer speed (faster than real-time) to how many clients? Time for re-wrapping and transcoding? What reliability and quality check?

9 Services/Processes Interoperability Video? Audio? Data 0? Metadata Textual (XML), Binary Transcoder Container, Wrapper, File Formats (Material Exchange Format - MXF, MPEG-TS, etc.) Re-Wrapper Ingest Edit plugging software Protocols components together mapping into the transports, adding identifiers, adding timing, QoS (IP, TCP, UDP, RSVP, RTP, etc.)

10 Services/Processes Interoperability??? Ingest Transcoder Re-Wrapper Ingest Edit EBU AMWA FIMS Framework for interoperable Media Services

11 How far away is 80p/50 from mainstream? Let s review on what is there 1. Infrastructure: uncompressed 3G SDI Router, switcher 2. Cameras: High-End type cameras available, and consumer cameras 3. Studio compression: HDCAM-SR (and light) AVC-Ultra JPEG 4. Degree of overlap with 3D (2x 80p/25, 2x 80i/25, 2x7p/50) in terms of bitrates

12 How far away is 80p/50 from mainstream? Let s review on what is missing 1. Mainstream cameras Sensor technology?, 3G SDI level agreement, adequate pricing? 2. Mainstream compression system 3. Business case Codec with reasonable bandwidth requirements (storage, network load) at very good quality up to 7 th generation Bit-streams standards for MXF Can one appreciate the quality difference? Can I created more value of content with 80p/50? Distribution to the home (STB) an option? Co-existing business model with 3D?

13 Some side thoughts...looking at the industry Wouldn t it be nice, if... Drive for an agile decoder Understands the MPEG family Can do 80p/50 Define a HD master format that limits to one common TV production image format (80p/50) Common Metadata solution at the acquisition iti point

14 EBU Strategic Programme: SP-HIPS Harmonisation and Interoperability of HDTV Production Standards MXF Interoperability New studio codec tests TC, Subtitles, Constraint(?) Testplan, Test Content, (chaired by IRT, C. Nufer) Codec test (6 month) (chaired by RAI, M. Visca) Acquisition Metadata Tech. Metadata, Descriptive (chaired by RAI, D. Airola) Strong Industry Commitment (Sony, GV, Panasonic, Snell, Avid) Best Practise on 3G SDI Draft Best Practise (chaired by BBC, A. Quested)

16 What to take away 1. Current situation in file based HD production is a mess but the work between EBU, industries, associations and standards bodies is providing good direction 2. This cooperation's, in an aggressive time schedule have already provided success points 3. 80p/50 in production is part of many vendors strategies, but not yet mainstream (cost),...it will have impact to mainstream in the next 2-4 years (3D implications) 4. Join the work if you want to be part of the developments
