  • Tablets and Television - How tablet PC's will impact the Nature of Television Production

    1. 1. Television and Tablets How Tablets will impact the Nature of Television Production<br />
    2. 2. Limecraft<br />Limecraftis a media technology startup. We provide software and services to the audiovisual professional.<br /><ul><li>Facts
    3. 3. Incorporated May 2010
    4. 4. Spin-off of Ghent University, IBBT and VRT

    10. 10.</li></li></ul><li>Example – enable live flash-encoded content on iPad<br />Problem – Cupertino doesn’t like adult entertainment on iPad<br />Objective – Enable live services on iPad<br /><ul><li> Transcoding of Flash/VP6 into iPAd Quicktime (H.264/AAC)
    11. 11. Real-time processing of live content - delay of 5 seconds
    12. 12. 800 kbps to 500 kbps with a increased image quality(!)
    13. 13. Variable bitrate encoding</li></li></ul><li>Example – Telenet Yelo (Over the Top Television)<br />Courtesy of Telenet NV<br />Objective – Integratelive TV and Video on Demand<br /><ul><li> The EPG enables access to live and on demand broadcast services
    14. 14. Ffmpeg/x.264 transcoding @800 kbps enables excellent quality
    15. 15. A adequate DRM system(!) for protection of content against unauthorised reproduction or retransmission</li></li></ul><li>Provisional Conclusion<br />Tablets and Television<br /><ul><li> Tablets are easy enough and enable a quality which is good enough for competing with conventional television services
    16. 16. Distribution of television signals to tables is uniquely via IP, and preferably using some form of adaptive bitrate streaming
    17. 17. Transport via IP has the potential to brutally replace DVB.</li></ul>But:<br /><ul><li> we need a standard file/streaming/metadata –format
    18. 18. we need a standard transport protocol
    19. 19. we need a different production process !!!</li></li></ul><li>A tablet personal computer (tablet PC) is a portable personal computer equipped with a touch screen as a primary input device and designed to be operated and owned by an individual.[2]<br />(Source:<br />

    24. 24. January 27th, 2010 – “You’ve got the internet in your hands...”<br />Apple released the first iPad in April 2010, and sold 3 million devices in 80 days.<br />By now, more than 16 million iPads have been sold — more than all other tablet PCs combined.<br />
    25. 25. Why now and why it will work this time...<br />Technology<br /><ul><li> Solid State Storage

All of this leads to substantial CAPEX and OPEX.<br />Streaming Server Farm<br />(CDN)<br />Video Encoders<br />(Telestream/Agility)<br />
    34. 34. The Cause of the Problem it the Marketplace<br />The marketplace is extremely fragmented, which makes it difficult for a production facility or a broadcaster to set up an integrated and cost effective solution. <br />
    35. 35. Provisional Conclusion (2)<br />1/ Current television and film production best practices are optimised for linear television and are not (yet) adapted for non-linear distribution of content.<br />2/ The technology required to extend conventional production by alternative distribution channels is quite new and in evolution.<br />3/ As such, re-use of content often results in:<br /><ul><li> Disproportional cost
    36. 36. Poor image quality
    37. 37. Lousy user experience</li></li></ul><li>Issue N°1 - Cost<br />Acording to information publishished via the Freedom of Information act, BBC would have spent 23.2 M£ (~26.5M$) from 2005 to 2010 on the development of BBC iPlayer, excl. commercial software licenses. <br />The operational cost is 3.9M£ (~4.5M$) per year, primarily technology-related and excluding distribution cost. <br />BBC iPlayer broke records in January 2011, receiving 162 million requests for TV and radio programmes on an average of 4.4 million daily, marking an increase across all devices, all to the highest recorded figures to date.<br />
    38. 38. Issue N°2 - Poor video quality<br />While the current “best practices” in terms of videocompression may be sufficient for talking heads, they show very low tolerance to moving or complex images.<br />-> Encoding for over the top distribution requires extremely variable bitrate encoding and large GOP sizes.<br />
    39. 39. Issue N°3 - Lousy user exp<br />Current “best practices” result in a televion programme which will be scheduled for linear distribution. It is difficult or impossible to automatically enable item-based viewing and no metadata is available to enable interactive search and retrieval of items.<br />-> The next generation of content production systems needs support for model-driven development, resulting in custumisable and automatically re-produced versions of the master<br />

    43. 43. Step 3 – Explore new Formats<br />Non-linear television will be chapterised, include search functionality and provides carefully selected links to related content and advertisement<br />
    44. 44. Challenges<br />Tabletswilleventuallylead to new user experiences and formats, but currentproduction and distribution methodsare not sophisticatedenough:<br /><ul><li> File formats – a common data model and embeddedmetadataare the key to interoperability;
    45. 45. A new type of IntegratedAsset Management system must provide native support for 360° distribution – additional distribution channels are available at marginal cost;
    46. 46. New production methodsbased on model-drivendevelopment are the key to production automation, customisableproducts and interactivity;</li></ul>24<br />
    47. 47. MXF – the production file format<br />Objective –Robust and Simple<br /><ul><li> reduce 95% of the interactions to simple file transfer
    48. 48. Integration based on embedded metadata
    49. 49. MXF-DMS1 is the prefered option
    50. 50. Current commercial software is highly inefficient(!)</li></li></ul><li>Production<br />(Storytelling, capturing, editing)<br />Packaging and Labelling<br />(Master Control)<br />Distribution<br />(Broadcast transmission, streaming servers)<br />Playout and Interaction<br />(Television, Tablet Device, Browser)<br />Adobe<br />Apple<br /> Microsoft Google<br />HTML5<br />Master Control<br />API’s<br />Script, Breakdown<br />H.264, AAC, embedded metadata<br />VP8 (Google) – H.264, AAC (Mpeg)<br />MXF (SMPTE)<br />Matroska, m3u8<br />RTSP – Mpeg2TS – Mpeg Dash<br />Mpeg2TS<br />NTP - RTP - HTTP<br />FTP<br />But, quid with the distribution format???<br />
