Chapter 1 Product Overview
Overview
• Provides a single content delivery network for serving set-top boxes (STBs), PCs, and mobile
devices
• Supports content security and encryption
• Supports narrowcast service such as VOD, time-shifted TV, and switched digital video (SDV)
sharing the same infrastructure
• Supports both traditional and next-generation STBs and headends
Real-Time Splicing of MPEG-2 Transport Streams
The ISA Stream Extensions feature allows real-time splicing of MPEG-2 transport streams as identified
by the Society of Telecommunications Engineers (SCTE) 35 standard. The embedded SCTE 35 cue
messages contain information for digital program insertion (including advertisement insertion) in live
content as well as content recorded for the purpose of enabling time-shifted on-demand services.
Pre-roll, post-roll, and mid-roll placements of digital program insertion, that is based on a playlist
structure, is supported on a CDS in an ISA environment. The Vault detects the SCTE-35 cues and
processes them at the time of ingest. The StreamExtChannel event channel on the CORBA
NotificationService is used to send ContentSignalingEvents that contain the SCTE-35 cue information
to the backoffice.
Note The SCTE-35 cue message cannot be greater than 400 bytes.
CDSM Configuration
To configure this feature set the TME/SCE field to Enable for MystroMDN.
The TME/SCE field is located on different CDSM pages, depending on the type of system configured
(VVI or CDS).
• In a VVI with split-domain management, on the VVIM GUI, choose Configure > System Level >
Distributed ISA Setup or Configure > System Level > Shared ISA Setup
• In a VVI with split-domain management, on the Stream Manager, choose Configure > Array Level
> VHO ISA Setup
• In a VVI with central management or a legacy CDS, choose the Configure > Array Level >
Streamer BMS
Note The configuration change for the ISA Stream Extensions feature requires that the ISA service is restarted
on both the master Vault and the Master Streamer. To identify the master Streamer and master Vault, use
the CDSM Monitor Services page to find the Streamer running the master stream service and the Vault
running the Content Store master. See the “Services Monitor” section on page 5-40 for more
information. To restart the ISA service, choose Maintain > Services, select the check box for ISA, and
click Submit.
Dynamic Modification of Playlists
The following dynamic playlists modifications can be performed on playlists that have been defined and
created:
• Delete_Segment—Remove a segment from the playlist
• Replace_Segment—Replace a segment in the playlist with one or more segments
