These release notes describe the features and caveats for all releases in the Cisco VDS-TV Release 3.9 train.These release notes are updated with each release in the train. For a list of the caveats that apply to this release, see the Caveats
The following information is in the release notes:
Starting from Release 3.9.1, AVSDB application in VDS-TV supports 512 replication servers (including vaults, streamers, cache nodes and controllers). The CServer replication is restricted to only 512 servers. For example, the number of VDS servers supported in streaming domain (streamers + cache) is 512. As part of this feature, VDS-TV supports the following enhancements.
A new application collectd runs on each node/server and performs the following functionalities:
– Collects status and statistical data in each node.
– Directly uploads data from each node on to the Controller (CDSM/VVIM) over a TCP connection.
– The collectd application running in the controller acts as a receiver and receives the data from each node via TCP. This data is stored in the memory cache and is predominantly used for real-time monitoring.
The Controller (CDSM/VVIM) which earlier used statsd and connected to AVSDB to obtain the statistical and monitoring data will now connect to collectd to obtain the same data.
To scale to 512 devices, AVSDB is enhanced to use hierarchical replication. A large replication domain is logically split into smaller replication groups. In each replication group, a node is selected as a replication master, referred to as replication group master. A server can never be a member of more than one replication group.
The page load time for the CDSM/VVIM GUI pages are optimized to support 512 servers.
The replication frequency of NOD_LOAD table is changed from 2 secs to 20 secs. When there is a change in the server load value, it is replicated immediately and when there is no change in the server load value it is replicated every 20 secs. The replication frequency can be changed by modifying the load_interval <no of seconds> in /home/isa/.avsdb config file. If the value configured is more than 20 then the value is ignored and the replication frequency is considered as 20 seconds.
For additional information on server scalability, refer Cisco VDS-TV ISA/RTSP Configuration Guide, Release 3.9.
Starting from Release 3.9.1, Cisco VDS-TV is certified to support a maximum of one million assets in the overall system. As part of this feature, VDS-TV supports the following enhancements:
The database for the content object and tables is redesigned to support less space per content. For detailed information on database migration procedure to be followed during upgrade/downgrade process, refer Cisco VDS-TV Installation, Upgrade and Maintenance Guide, Release 3.9.
An offline script is used to collect all the damaged GOIDs and the option to view the damaged GOIDs from Content Ingest page in GUI is removed.
The latest GOID information can be obtained from the Content Details page. For additional information, refer Cisco VDS-TV ISA/RTSP Configuration Guide, Release 3.9
Future Recording Support
Starting from Release 3.9, Cisco VDS-TV supports future recording playlist elements in the SETUP request. The playlist elements can contain VOD (recorded data), live content and future recording data. When a STB enters time shift mode, the back-office sends a SETUP request with several playlists to the streamer containing 8 hours of time shift content. The RTSP server validates the playlist elements and if all are valid, the RTSP server sends 200 OK to the back-office. The RTSP server also supports switch between valid playlist elements on FF, RW or 1X play.
TCP Window Scaling for RTSP NGOD deployment
Starting from release 3.9.1, Cisco VDS-TV supports TCP Window scaling in vaults/streamers and cache in RTSP NGOD deployment.
UCS C220 M4 2U1 Hardware Support for the Controller

Starting from release 3.9, VDS-TV supports a new make model for installing/upgrading and downgrading the VDS-TV software. For detailed information on Installing, Upgrading and Downgrading VDS-TV software, refer Cisco VDS-TV Installation, Upgrade and Maintenance Guide, Release 3.9.
Cisco AMS Enhancements
Starting from release 3.9.1, VDS-TV supports the following features to achieve increased publish scalability:
Concurrent publishing of packages to the markets where multiple threads are spawned to service each market.
A publish time out value configured via GUI is used to avoid any publishing blockage due to network latency, backoffice errors and publishing errors. If the market does not respond within this timeout value, the package publish fails.
FTP load balancing support to allow usage of capacity across vault group for content transfer to markets.
Prioritizing the packages for publishing in case of a backlog of packages to be published to the corresponding VOD market site(s).
Support for ingest from dual locations.
Support for fully qualified content names in case different providers ingest packages with same file name for video assets.
VDS-TV also supports additional REST APIs for the following:
View the list of package priority rules.
View the complete history of package flow in the system and
View package ingest statistics and package publish details of list of packages in the system.
For additional information on REST APIs, refer Cisco VDS-TV API Guide, Release 3.9
Starting from release 3.9.1, VDS-TV supports the following GUI enhancements for MVOD deployment:
SFTP support for auto and manual ingest of tribune data.For additional information refer, Configuring the Media Importer/Exporter, Uploading an EPG File sections in Cisco VDS-TV ISA Configuration Guide, Release 3.9.

New Features in Cisco VDS-TV Release 3.9.1 ES1
4K HEVC Video Support
At present, VDS-TV supports only ingestion and streaming of MPEG2 and H264 video content with a maximum resolution of 1920X1088. Starting from Release 3.9.1 ES1, VDS-TV supports ingestion and streaming of 4K HEVC video with a maximum resolution of 3840X2160.
The ingestion process is enhanced to support 4K-HEVC video content. While ingesting 4K-HEVC video content, VDS-TV generates 1x file, delta and index files but FF/RWD are not supported for HEVC video content however trick files are generated for 4K-HEVC video content as specified in the bug CSCuw97819.
The VDS-TV streamer is enhanced to support streaming of 4K-HEVC video content at a maximum bit rate of 29Mbps.
At present, testing is done only with a limited set of contents.
No support for trick play for 4K-HEVC video content. Only Setup,1X play, jump, pause resume and Teardown are supported.
Tested and verified 4K-HEVC video content encoded at a maximum bit rate of 29Mbps.
4K-H.264 video content not validated and not supported for Cisco VD-TV 3.9.1 ES1 release.
Release 3.9 of the Cisco VDS-TV supports both the ISA and RTSP environments. Some RTSP environment features are only applicable to certain RTSP Deployment Types.
The Cisco VDS-TV Release 3.9 does not run on the CDE100, CDE200, CDE300, and CDE400 hardware models.
Cisco recommends Mozilla Firefox 36 and above as the primary browser to access the CDSM GUI. Internet Explorer 11.0 can also be used as a secondary browser to access the GUI.
Warning Do not change the timezone of any of the VDS server (vault, streamer, controller and cache) when AVSDB is running since the archiving of data is based on the time expired.
The 3.9.1 streamer crashes when primary streamer failover is triggered from a lower version streamer (<3.9.1) to a higher version streamer (version 3.9.1) while the streams are active. To resolve this issue, download the patch vdstv_3.9.1_b26.bin and apply it on the streamer immediately after upgrade to version 3.9.1. Start the services on the streamer only after applying the patch.
Note This issue is applicable only to RTSP environment with more than one streamer in a stream group.
Caveats describe unexpected behavior in Cisco VDS-TV software releases. Severity 1 caveats are the catastrophic caveats that cause the entire system to fail or a major subsystem to stop working; severity 2 caveats are severe caveats where important functions are unusable, and there is no workaround, but the other functions and the rest of the network operates normally.. Severity 3 caveats are moderate caveats where things fail under unusual circumstances, or minor features do not work at all, or things fail but there is a low-impact workaround.
