Improve Performance and Reliability
Digital cable consumers expect reliable, high-quality entertainment, information, and communications experiences. Cisco cable solutions, products, and systems, including digital headends, deliver the performance and reliability that are essential to successful analog and digital cable operations.
Increase Flexibility and Control
The unified end-to-end Cisco Digital Video Delivery System offers:
- Simplified integration of broadcast linear TV, video on demand, switched digital video, and other services
- Service and transport flexibility, with the ability to deliver MPEG-2 or MPEG-4 services, and a future migration path to IP video services
- Full control over how a service looks and how it can dynamically change over time
- Flexibility to change services and channel lineups easily
- Full redundancy, including different backup scenarios
End-to-End Digital Headend Solutions
A digital headend consists of multiple building blocks. Cisco has a dedicated solution for all headend elements, based on flexibility and open standards. Depending on the IP router, digital headends perform multiple functions, including:
- Acquisition: Services are acquired, preprocessed, and distributed in an IP format.
- Processing: Multiple steps include:
- Component remultiplexing
- Processing program-specific information (PSI) and specific information (SI)
- Transrating and statistical remultiplexing
- Monitoring the individual service, advertisement insertion, and scrambling
- Encoding: Encoding can be from analog or digital to MPEG-2 or MPEG-4 Advanced Video Coding (AVC), both high definition and standard definition.
- Quadrature amplitude modulation (QAM): High-density QAM products for data, voice, and video support both linear and nonlinear content.
- Management: A network operations center monitors and manages the individual services.
