TV CONTENT CREATION MULTIFACETED DEVELOPMENTS J K CHANDIRA DOORDARSHAN Video content creation, a dynamic and lucrative activity has attracted the attention of IT & Telecom industry for possible value addition. In turn, this has made plethora of mature technologies available to the broadcasters for possible exploitation This is in addition to the major developments in the imaging technology Developments in content creation 1. 2. 3. 4. Integrated IT based production workflow systems File based content acquisition – new media and contribution links High Definition – Image production and processing Interactive content creation systems. Base technologies Benefits of developments in • General electronics • Imaging and computing • Open software standards • Storage media and sub-systems • Networking technology & architecture • Telecom bandwidth and technology Standardization of Stream/File formats File format Features Use DV MPEG Steam format Low latency Low metadata Acquisition , Contribution, Emission DPX Uncompressed file format, some metadata Transfer of uncompressed images from telecine and server AAF Supports multiple codec Complex EDL, metadata For high-end editing MXF Industry wide collaboration Acquisition, contribution, archives, D-cinema, Wrapper format for Operations multiple codec Broadcast Industry ecosystem Multitude of access and distribution platforms Multi- channel scenario Increase in the pace of delivery Linkages with film and consumer video industry Where, when and how of the content delivery – decided by the viewer. Competition from across the industry border 1. Integrated workflow Seamless production workflow from acquisition to play out under MAM Search & Retrieve anytime, anywhere Digital tape less production and distribution Company wide media management – throughout production life-cycle. An integrated collaborative media frame work An enterprise solution & not a logistic tool MEDIA ASSET MANAGEMENT Search Retrieval Edit / Repurpose Ingest Playout MAM Log Catalog Transcode AUTOMATION Archive Benefits of integrated production Ability to encode & mange video at different resolution from web proxy to full broadcast quality for multiple distribution Integrated low cost desktop editing Single user interface for different data sources, hardware and application Integration of DRM & financials in the core workflow. Re-use of assets through attached long term storage and metadata 2. File based acquisition- New media and IP contribution Camcorders supporting new media for file based content storage do not require base-band ingest. Hard-disk based camcorders form Ikegami & Grass Valley, Optical media (Blue ray) based camcorders from Sony and Solid State memory based camcorders from Panasonic and others. DDR for studio and OB multi-camera recordings on non-linear media, as VCR replacement. Ethernet, Firewire, USB interface for media transfer File based acquisition- IP contribution links Transport of contribution video for production over IP networks ensures high quality at much lower cost. QoS technology in IP network ensures high bandwidth allocation to the video carrying IP packets. Ingest can be controlled by MAM over Wide Area Networks. 3. HD Production HD production technology opens new vistas for broadcasters. Dramatic increase in picture quality. HD offers opportunity for broadcaster to evolve future business model in the era of convergence. Servers, Post-production equipments and integrated systems support HDTV resolution. International exchange of programs – HD CIF resolution HD Production of Rich Content Digital Broadcasting DTT Digital Satellite DTH Digital Cable Rich Content Creation Digital Production in HDTV Format & Media Conversion IPTV HD DVD / Blue ray Internet/Web, DVB-H Film Recording Digital Cinema Critical Success Factors Sports & Movie Production Investment by Display device vendors Popularity of HD - DVD Critical Mass Of HD content Broadcast HD Transmission HDTV Broadcasting Falling price of Set top box Specialty Programs HD TV Archives Collaboration of Stake holders 4. Interactive TV Enhanced , data rich viewing experience by viewer interaction with TV content Return path by phone, SMS , cable etc Content management application and data broadcast middleware for multiple delivery systems DVB-MHP becoming popular as global standard Open TV, Liberate, - proprietary ITV solutions MHP- APIs broadcast as a part of program, set top- box downloads and executes the application ITV Value chain Format or Content Owner: Interactive and broadcast rights TV Channel TV Producer Advertisers, sponsors and merchants Communication Set top box, Mobile phone, Internet, PC, Landline, PDA etc Application Developers Games Developers MSO: Cable, Satellite or Terrestrial TELCO: Return Path - Mobile, iTV, Internet, Landline etc Consumer, viewer and participant Accountability Interactive data, response and ratings reporting PITFALLS Digital files are not permanent – Hardware and software changes are potential threat – systems require maintenance. Digitizaton is not value-neutral. It imposes its on quality and artifacts. Multiples standards and proprietary software exist in IT industry Strategy ? Bite off more than you can chew. It helps growth. If you can’t do it perfectly right away, buy time. Do what you can. Keep options open. Be a force for change. Take opportunities. Make deliberate choices – even if sometimes they are both wrong and arbitrary. Don’t work by default. Be inclusive. What you reject may never be recovered. What you keep today you can choose to discard tomorrow.
