This document discusses MPEG transport stream (TS) logging. It outlines how TS logging has become more feasible due to advances in software and hardware codecs, allowing entire TS streams containing multiple programs to be logged affordably. TS logging provides benefits like logging the legal interface, repurposing content, quality of service monitoring, and flexibility. The document reviews proxy logging and how Volicon's TS logging solutions include proxy generation for long-term storage and remote access alongside TS logging for analysis.

- 3. Agenda • Evolution of TV & Compliance Logging – Rationale & Technologies • Proxy Logging Review • MPEG TS Logging • Benefits of MPEG TS logging – Logging the legal interface – Repurposing, QoS, – Cost effectiveness and flexibility • Q&A
- 4. Historic Rationale Compliance Logging • Governmental compliance – Decency, Captions, Loudness,.. • Production Troubleshooting – Broadcast must be perfect – Improve the production process with review – Directorial or Technical • Advertiser proof of delivery – High value broadcast ads • Organizational warehousing – Historical review
- 5. History/Future of (TV) Compliance Logging 1930s 1960s 1990s 2000s 2010s
- 6. Logging Technologies Details Technology Interfaces New Utility VCRs & Analog QoE Monitoring DVD-Ws Logging Analog Analog (Computer) Random Access baseband Remote Access and Review compressed Practical advertising proof of delivery Proxy logging & storage for long periods SDI SDI & HD-SDI Advanced Metadata logging (AFD, .. baseband Multi channel/track audio logging (5.1+stereo) compressed MPEG TS ASI, IP, DVB-T, QoS Monitoring 8VSB, DVB-S,… Logging of all services (Bcast + Mobile + Inter) TS Log + proxy log Flexibility & Density
- 7. What is Proxy Logging? • Analog (SD) or SDI (HD or SD) • Too much information to log digitally 1.5 – Analog - ~300 Mbps Gbps – HD-SDI – 1.5 Gbps – 10.8GBs per Mbps per day – Solution: create and log proxy Original Scaled Encoded Proxy • Scale, then encode (H.264, VC-1) • SD - ~500kbps, HD – 1.5 Mbps 1080x1920 800x450 Encoded 800x450 1.5 G bps 1.5 M bps Proxy 260 Mbps H.264/VC-1
- 8. Proxy Logging Benefits •Affordability and Density • Manageable storage for 90+ days • Several channels per chassis •Access to critical metadata • Extracted and embedded in proxy • CC, TT, AFD, … •Remote Access to QoE – full frame rate A/V • Low enough BW to allow remote real time access But it is still a proxy not the original
- 9. Digital TV – Dist via Satellite or Over-The-Air • MPEG-TS compressed content is the product • More channels, same analog BW • First with satellite in mid 1990s– • Then Over the air in 2000s – MPEG2 HD – Why not log MPEG-TS in early 2000s? • Because it is harder to make the proxy – more $$ • Not as much additional metadata – MPEG proxy – same product initially baseband – Now we can log the MPEG-TS affordably • SW & HW Codec Advances • Many programs on 1 interface + IP interfaces!
- 10. MPEG TS Logging Business Drivers • Natural evolution of logging interface Baseband Uncompressed MPEG compressed Analog (HD)SDI ASI IP/Ethernet SD SD or HD One TS Many One PGM One PGM Several MPTSs PGMs 100s of PGMs
- 11. TS Logger: MPEG TS + Proxy • Log, Decode, Scale, Re-encode, Log – More Steps, more utility TS Logger Proxy Logger Your content Scale & Where you want Decode Encode When you want Base- band proxy MPEG-TS Analysis Proxy Log ASI, IP Results+ Metadata 8VSB, QAM Stream A/V LAN or WAN DVB-T/T2 MPEG TS Log Live or Historical DVB-S/S2 TS or Proxy PC or Mobile 1-100s of users
- 12. MPEG-TS Logging Features • Access to Live or Log Live • Live for air check, Log for review LOG • Different logs for TS and Proxy • Short term storage of original (e.g. 19 Mbps) TS Proxy • Long term storage of proxy (e.g. 1.5 Mbps) • Operate on LAN or WAN • Review of proxy, access to original • Export Proxy, TS of program or MPTS anywhere • Extraction and storage of metadata with proxy Proxy • Measure on original, store results in proxy Metadata • Log all or parts of the MPEG-TS MPTS & Results • Only keep what you need, or keep it all TS PGM
- 13. MPEG-TS Logging New Use Cases • New use cases • Repurposing – original HQ MPEG content – Navigation with proxy, access to original • MPEG QoS Monitoring – real time or off line – Captures the complete MPEG TS, log eliminates chronics • Monitoring Additional Metadata – DVB Subtitles, All audio tracks, Mobile-TV, … • Enterprise Cable TV replacement – – access to original content, able to go back in time • Future applications (Mobile, Interactive, …) – Automatically logged, enable troubleshooting
- 14. MPEG-TS Offerings from Volicon • Multitude of MPEG-TS Interfaces • ASI, IP, DVB-T/T2, 8VSB, QAM, … • Configurable TS Storage : 0d – 365d+ • Configurable Proxy Rates & Storage : 3d – years • On variety of platforms with different scalabilities • Scout – Single program - Xeon, ECC, SSD • Professional – up to 6 HDs, Xeon, ECC, RAID-5 • Enterprise – 1-20+ HDs, Xeon, ECC, RAID-6, 1+1 PS • Customizable to your needs
- 15. MPEG-TS Logging Summary • Includes Proxy logging • Long term QoE A/V storage, remote access, metadata • New Features • TS + proxy Logs, Proxy access to MPEG, off line QoS • New use cases • Repurposing, DVB-Subs, Mobile TV, … • Scalability, Flexibility, Affordability, Efficiency • MPEG TS log grows with evolution of delivered services • Improves operations with forensics/log of MPEG
