2 What is the UMID? Goal of UMID Applications UMID Applications in MXF UMID Application Project in SMPTE Conclusions 2012/6/19 2

3 Unique Material IDentifier Specified in SMPTE ST 330 & RP 205 (in 2000) Universal Label (UL): identifying as UMID (Key) Length (L): Length in byte that follows, fixed to 13 h (Length) Instance Number (Inst.#): indicating its originality Material Number (Mat.#): Globally unique value (Value) 2012/6/19 3

4 As a unique identifier New value for Mat.# Zero for Inst.# As a linking tool Shared value for Mat.# Non-zero for Inst.# AV Material UMID Mat.#="AAA" Inst.#="0" Source AV Material UMID Mat.#="BBB" Inst.#="0" Result AV Material UMID Mat.#="BBB" Inst.#="1" These uses are mutually exclusive! In 2012/6/19 4 Out

5 To link an AV material to its metadata <Metadata xmlns="..."> <TargetMaterial umidref= U A "/> <Title>Major League Baseball</Title> : </Metadata> Metadata (1) U A Metadata (2) U B U C AV material(1) Metadata (3) AV material(2) AV material(3) 2012/6/19 5

7 SONY Because of huge It is difference Which AV material in their data sizes UMID= U A AV material. I have it at captures Ichiro Homerun? Application Uniform Where is management of 1 UMID= U A Needs metadata associated AV material? with AV materials 2 via UMID 3 Common UMID Resolution Protocol Database Metadata 4 Ingest Server Near-line Material Server Archive Playout Server 2012/6/19 7

8 SONY Application Metadata Database Ingest Server Near-line Material Server Archive Playout Server 2012/6/19 8

9 SONY Application Layer Application Metadata Database Ingest Server Near-line Material Server Archive Media Layer Playout Server 2012/6/19 9

10 Needs industry common UMID resolution protocol To resolves a given UMID of AV material to its URL Clarifies UMID Application Principles To realize UMID based AV material management 2012/6/19 10

11 Principle 1: UMID Integrity Different AV materials shall be identified by different UMIDs U C AV Material U C AV Material Principle 2: UMID Identification What the UMID identifies is the essence representation at its playout U D U D AV Material AV Material Title A Title B 2012/6/19 11

12 Embodiment of UMID Application Principles Material Manager UMID URL U 1 Material 1 U 1 Material 2 U 3 Material 3 Physical Medium U 4 Material 4 U 5 Material 5 U 6 Material 6 Material 1, 2, 4 and 5 constitute UMID Managed Domain 2012/6/19 12

13 For AV material import into UMID Managed Domain Attach a newly created UMID Except for AV materials from other UMID Managed Domains For AV material modification Replace existing UMID with a new UMID value U E AV Material U EG AV Material 2012/6/19 13

17 Material exchange Format Specifies in SMPTE ST 377, etc. Physically: Sequence of KLV(Key-Length-Value) packets Logically: File Header, File Body and File Footer 2012/6/19 17

18 Two kinds of metadata for Header Metadata Structural Metadata Descriptive Metadata Structural Metadata tree Preface Identification Content Storage Essence Container Data Material Package File Package Describes AV material 2012/6/19 18

19 Material Package (MP) and File Package (FP) FP: Describes material within a file MP: Describes material at its playout Not always the same UMID UMID FP MP Essence in File.mxf Essence at Playout UMID@MP must be a unique material ID! 2012/6/19 19

20 Material Package UID (MpUmid) Used to uniquely identify an AV material (MXF file) File Package UID (FpUmid) May be used for other purposes MpUmid Mat.#= XXX" Inst.#="0 MpUmid Mat.#= ZZZ" Inst.#="0 FpUmid Mat.#= YYY" Inst.#="0" AV Material Source.mxf In Out FpUmid Mat.#= XXX" Inst.#= 1" AV Material Rresult.mxf 2012/6/19 20

22 Proposed on March 8 Approved on April 10 Ready to go on May 15 Chair Yoshi Shibata Editor Jim Wilkinson SG: Study Group 2012/6/19 22

23 Explore the Best Practice of UMID applications. UMID based AV Material Management, etc. Identify typical UMID Application Principles How to implement UMID Managed Domain Identify relevant Technologies needed to be Additionally Standardized. UMID Resolution Protocol, UMID App. in MXF, etc. 2012/6/19 23

24 Meeting Action Apr. May June July Aug. Sept. Oct. Nov. Dec. Jan. Feb. Mar. Promotions Bristol Geneva Melbourne??? UMID App. Conference Paper/patent survey Intermediate report - UMID app. principles Final report - Best practices - Future standardization 2012/6/19 24

25 UMID can be much more useful! Under appropriate common rules for its applications MXF adopts UMID as its mandatory component To be the media IT infrastructure for the future filebased media production system SMPTE TC-30MR SG UMID Applications Has just begun We need your expertise!
