Logging Technologies Details
What is Proxy Logging?
• Analog (SD) or SDI (HD or SD)• Too much information to log digitally
– Analog - ~300 Mbps– HD-SDI – 1.5 Gbps– 10.8GBs per Mbps per day
– Solution: create and log proxy• Scale, then encode (H.264, VC-1)• SD - ~500kbps, HD – 1.5 Mbps

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
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 –
– same product initially
– Now we can log the MPEG-TS affordably• SW & HW Codec Advances• Many programs on 1 interface + IP interfaces!

MPEG-TS Logging Features
• Access to Live or Log• Live for air check, Log for review
• Different logs for TS and Proxy• Short term storage of original (e.g. 19 Mbps)• 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• Measure on original, store results in proxy
• Log all or parts of the MPEG-TS MPTS• Only keep what you need, or keep it all

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
MPEG-TS Offerings from Volicon
