Chapter 1 Product Overview
Overview
TV Streamer CDA
The TV Streamer CDA is used for VOD delivery systems. TV Streamers are responsible for
personalizing content and playing that content out under subscriber control.
TV MediaX Suite CDA
The TV MediaX Suite CDA offers a set of tools that simplify content ingest workflow and scheduling
tasks for both asset-based and real-time content. The TV MediaX Suite CDA consists of the following
features:
• Publisher—Coordinates the ingest of pre-encrypted content.
• Scheduler—Schedules real-time content or imports the schedule from an electronic program guide
(EPG).
For information on configuring TV MediaX, see the “TV MediaX Configuration Workflow” section on
page 3-11.
TV Playout CDA
The TV Playout feature is for ISA environments and includes Public, Education, and Government (PEG)
channels and Barker Streams. PEG channels differ from traditional broadcast channels in that the service
provider itself must ingest and stream the content rather than receiving and forwarding a satellite feed.
For information on configuring TV Playout, see the “TV Playout Configuration Workflow” section on
page 3-12.
Content Delivery
The CDS delivers real-time, time-shifted, and on-demand video content to set-top boxes, personal
computers, or any other device accessible through a Service Provider network.
The Cisco VVI allows service providers to support a broad range of services. For example, with the
ability to distribute content from anywhere to anywhere, operators can provide user-generated and online
video just as easily as any other on-demand title. The ability to deliver content with sub-second latency
also lets service providers dramatically expand the video library that can be made immediately
accessible to customers, allowing them to access content that resides in a different state or country
virtually instantly.
Operators can also support popular real-time and time-shifted services, such as letting viewers tuning
into a program in progress and restart it from the beginning, or providing network-based personal video
recorder (nPVR) functions such as the ability to pause, fast forward, and rewind live TV. The Cisco
VVI's centralized storage and localized streaming architecture also distributes screen-formatting
processes to the network edge.
The key content delivery capabilities include the following:
• Supports multiple content formats (high-definition and standard-definition content, multiple video
codec formats, multiple media file types, and so on)
• Supports ingest and streaming of real-time video services, VOD services, and Internet video
• Supports advertising content distribution and streaming
• Supports nPVR capabilities to provide a digital video recorder (DVR)-like experience with the
network
