Course Outline

This course provides the essential technology understandings required by all telephone company employees who are implementing IPTV over ADSL2+ and/or fiber circuits.

Telecom Service Providers are commonly implementing IP television via a consortium of vendor products and technologies. These vendor products/applications include IP multicast head end video/MPEG rate adaption devices, middleware servers, video on demand servers, emergency alert systems, caller ID systems, encryption devices, fiber optic ONT’s, HPNA devices, video enabled Occam BLC’s and ADSL2+ modems. In some cases service providers will also be implementing web access services from the television as well.

This course provides the end-to-end understanding of IP Television’s technology components as well as how they are all integrated into a single application over ADSL2+ and/or fiber circuits and through the Occam BLC (Broadband Loop Carrier) equipment.

Expect a refreshing mix of technology details and clear explanations, interspersed with actual IP Television product and technology video examples; all within a refreshingly dynamic and engaging presentation!

Dates/Pricing

*Special Vendor Hosting Rates at Occam Headquarters:
Occam Networks will be scheduling this course for a limited number of sessions at their Santa Barbara headquarters. A special discounted rate has been established for Occam customers at these sessions.

Course Details

• Video and Digital Television Fundamentals:
• Traditional analog broadcast TV concepts (black & white, color)
• Digital television and IPTV
• Digital television/MPEG compression basics as they relate to scene changes and variations within and between frames.
• Macroblocks - how does a single bit error affect MPEG communications - Why doesn’t a bit error just throw off a single pixel on the TV screen
• Variable versus constant bit rate MPEG coding
• How and why do high action sports channels require a higher bit rate than some of the other channels
  MPEG as it relates to Tiling/Macroblocking/Pixelating - how and why does it happen - how to professionally communicate this issue to the customer
• The head end multicast source device that clamps/transrates the variable bit rate MPEG to a constant bit rate (e.g. speeds such as 3.2 Meg, 3.5 Meg, 3.7 Meg, 4.0 Meg, etc.)
• Bit per second rates at the head end as this relates to quality/resolution and the number of set top boxes allowed
• How to troubleshoot tiling/macroblocking
• ADSL line error rates – corrected errors versus uncorrected errors – how does this relate to tiling.
• What tools/statistics are available in the Occam BLC and how to interpret them
• Fiber optic circuit error rates, troubleshooting
• TV interface connectors/set top box connection scenarios (composite, component, RF/coax, S-Video, HDMI, etc.)

• IPTV Fundamentals and Technology Components:
• Technology components of IP Television, features and applications
• The set top box, menu guides and functionalities
• Interfacing to the IPTV customer at their home
• Home networking scenarios and issues - Cat 5 wiring, Ethernet, HPNA/coax scenarios, etc.
• Video On Demand (VOD) and Subscription Video On Demand (SVOD)
• Middleware functionalities & their resulting appearances to the customer -
• What do you need to know
• Web Access from the TV and Walled Garden
• Caller ID on the TV, pause live television, personal video recording, digital music, Pay Per View
• EAS-Emergency Alert Systems, video encryption
• The differences between PPV and VOD as it relates to streams through the telecommunications network and the Occam BLC
• How are the TV and music channel streams passed through the BLC network
• What are the multicast addresses used for in IPTV
• How does channel changing occur in IPTV - why does it take longer when compared to analog/RF TV - where are the TV channel streams emanating from - is there a local component to this
• What is involved within the Telco distribution network which eventually brings the stream into that remote Occam BLC and that requesting subscriber

• IPTV operation over ADSL2+:
• Legacy ADSL/G.DMT, ADSL S=1/2, ADSL2, ADSL 2+
• The electrical properties of twisted pair circuits as they relate to ADSL in general, video/data over ADSL2+
• ADSL modems supporting data & video - configurations specific to IPTV - ATM
• VPI/VCI mapping to physical connectors
• Line speed issues as they relate to MPEG rates, and therefore, number of set top boxes and tiling possibilities
• Occam BLC fundamentals and configurations as they relate to and affect the ADSL circuit - video enabled Occam BLC
• Bit error monitoring and issues at the DSLAM/BLC
• What are the specific requirements for IPTV/video
• How do the following affect what the telco technician sees at installation - Occam BLC profiles, Fast vs. Interleave bit rates, Minimum/maximum rates, impulse noise values 0-3, SNR margins, target noise margin
• Corrected errors vs. uncorrected errors - how does this affect data vs. IPTV
• Continuity count errors in the Occam BLC - what does this mean
• ADSL 2+ measurements as well as how they affect both data and video
