Chapter 1 Product Overview
Overview
• Splice_Segment—Insert one or more segments at a specified NPT start value or NPT end value
within an existing playlist segment
• Add_Segment—Add one or more segments after a segment in the playlist
Note Each playlist can have up to 64 content elements.
The CDSM provides augmentations to the Stream Play History report. The Stream Play History report
first displays the Session ID Summary. When a session ID is clicked, if a playlist was streamed for the
session, the Session Playlist History report is displayed.
Note The Trick Mode Capture feature must be enabled to access the Stream Play History reports.
Content Chunking
For DVD on Demand solutions and long recordings, Release 2.5.2 supports ingest and streaming of
assets up to 120 GB in size and recordings that last longer than 12 hours. This is accomplished by
dividing the asset into multiple chunks of approximately 16 GB each.
Note The Content Chunking feature is disabled by default. All the CDS servers in a deployment must be
upgraded before enabling this feature. To enable, the following line must be added to the setupfile of
each CDS server and the server must be rebooted: content id type 2
Trick-Mode Restriction
Restriction of trick-mode controls (pause, rewind, fast-forward) per playlist segment is supported.
If a client issues a trick-mode command for a locked-out playlist segment or attempts to bypass a
trick-mode restricted segment by jumping to the next segment, an LSC_NOT_PERMITTED response is
sent to the set-top box. If a client has sent a fast-forward trick-mode command and a restricted segment
is reached, the stream continues at normal play speed and an LSC_DONE response is sent to the set-top
box with the NPT of the beginning locked out segment. An LSC_NOT_PERMITTED response is also
sent to indicate that the LSC_DONE is due to a locked out trick-mode segment.
The CDSM GUI provides the ability to configure these settings on the MPEG Tuning page (Configure
> System Level > MPEG Tuning).
HTTP Live Streaming
HTTP Live Streaming is fully supported; similar to live streaming over Cache Control Protocol (CCP).
The enhancements to HTTP Live Streaming consist of the following:
• Catch-Up to Live
• Play While Ingesting the Same Content
Catch-Up to Live
A video player can play live content close to the live point, within 2.5 seconds of the live point, without
macroblocking or leaving artifacts on the screen of the player.
