1. The document discusses Teleste's technology for video processing and delivery in cable television networks, including various receivers, transmitters, and methods of video delivery over cable, IP, terrestrial, and satellite networks. 2. It presents four cases of video headend network configurations, including centralized and distributed reception and processing, as well as delivery to subscribers via QAM or IP encapsulation. 3. It shows examples of how video headend networks may evolve over time from today to tomorrow to the future, with centralized processing and delivery of video over IP becoming more prevalent.

Case 1: EDGE QAM
Important
• Density: number of QAMs per 1U
• All Edge QAMs should have the same
configuration if possible
• Flexible output settings (e.g. frequencies)
• Intelligent 1+1 , many automatic triggers
instead of the manual management
Video processing
• PID passthrough/remapping/filtering
• Possibility to store and stream PSI/SI
tables if they disappear from the input

Case 2: IP Out MUX & Centralized reception
Important
• Versatile input options
• 1+1, usually feeds all EDGE QAMs
• Supports all major CAS vendors
• Easily managed PSI/SI table insertion
Video processing
• Decryption
• PID passthrough/remapping/filtering
• Multiplexing
• The encryption is often required

Case 3: Centralized reception and EDGE QAM
Important
• Usually for smaller networks
• Receivers and trasmitters at the same
site
• Could be a regional video HE
Video processing
• Decryption (if needed)
• PID passthrough/remapping/filtering
• Multiplexing and/or remultiplexing
• The encryption is often required

Summary
Thank you!
1. Understanding broadcasting tomorrow, besides video and cable television DNA,
requires strong DOCSIS and DAA experience
2. Video headends should be flexible to meet requirements today, tomorrow and
day after tomorrow
3. Linear television delivery systems change, but it will take a lot of time
