Sametime 9 Video Technology
Video MCU


Completely software based audio/video conferencing solution
without any custom hardware requirement
Relays H264 AVC and SVC video to video enabled clients
–



Supports Scalable Audio Coding (SAC) to Sametime 9 Clients
–
Layered Audio, mixed at client.
When all endpoints are SVC-enabled, there is no need for media
transcoding
–
Support audio transcoding and audio mix for clients which
don’t support SAC
Provides interoperability with previous generation standards-based
endpoints
–

6
Works by adaptively relaying appropriate SVC layers to
clients
Mixed audio & H.264 AVC video
Highly scalable, with optimized network use
Scalable Video Coding (SVC) and Continuous Presence

SVC enables the efficient encoding of video that can be
realized at different resolutions, frame rates, quality

A video image is organized into layers; clients choose how
many layers to receive and process.

SVC is more robust since transmission can gracefully
degrade to lower frame rates / resolutions when
experiencing packet loss.

Continuous Presence is effectively built-in, since each client
can request video from multiple participants (at reduced
quality, if necessary), and then compose the layout locally.

Actual number of streams depends on network bandwidth
and CPU processing power of the client machine.
User can also decide number of video streams to receive by
selecting the user layout.

7
Scalable Audio Coding (SAC)
10K

The VAD (Voice Activity Detection bit) and Energy levels
(for active speaker identification) are carried in the RTP
header.

Utilizes the Loss Packet Recovery mechanism (Good
quality even in very noisy lines).

Sametime 9 Video Features
Conference Modes

Two types of conferences supported
–
–
–
SVC – Supports only SVC enabled clients e.g.
Sametime 9 client
SVC + AVC – Also called as Mixed Mode. Supports
IFR1, external SIP device in the conferences.
MCU does the media mixing between SAC and
other codec. Video is always relayed.
Managed through User Policy

–
Through Conference Template
AVC client (8.5.2 IFR1) receives only one
video stream

Sametime-9 client can receive multiple
video streams

10
Conference Type
SVC/Mixed
Persistent Video Room & Dial-In


Users get provisioned automatically with at
least one Video Room
Users can request more Video Rooms
depending on the Video capability they would
like to have
–
–
–

Persistent Video Room allows SIP dialIN in a
Video Enabled Sametime Meeting Room
–
11
Video Room1 with a standard 180p video
Video Room2 with HD Video
Same provisioned room can be accessed from the
browser, UIM and mobile devices
Use the SIP URI of the room provided in the
Conferencing Info
Scalable Video Coding (SVC) - Layers



Farm based deployment model realized with
Load Balancer which in turn is fronted by IP
Sprayer.
All the http and SIP communication goes
through IP Sprayer. IP Sprayer selects a
random Load Balancer.
Load Balancer is aware of each VMGR node
and returns a least loaded VMGR node.
Load Balancer maintains a mapping of VMR
and host name of the DMA node.
Each subsequent calls to a VMGR is
intercepted by the LB. LB checks the mapping
of VMR and VMGR host node and redirects the
call to the selected VMGR node.

Points to remember



It is mandatory to exchange certificates between Media Manager and Video Manager and vice versa. Note it is also necessary to
restart respective servers once certs are exchanged.
When VMCU is added to VMGR , we need to use VMCU password that was set during deployment plan creation. It is also
recommended to restart VMCU after this.
VMGR's VM is restarted. After restart WAS server is started without restarting solid db. All the restart steps need to be followed in
proper sequence.

VMGR should be installed with root privilege and requiretty should be disabled before installation begins

VMGR should not be installed on internet/public network. If already installed for timeperiod, DNS lookup needs to be disabled.

On VMGR clustered environment it is necessary to add VMGR LB's HTTPS port in VH of WAS SIP Proxy fronting CF cluster.


35
In case of clustered deployment of media server(CF/PR and VMGR) it is necessary to add FQDN of WAS Proxy fronting PR cluster or
LB VIP in PR Domain List.
Manually changing stavconfig.xml →
–
Make sure to make changes in the Deployment Manager and Media Server Nodes
–
Make sure to restart all the servers including SSC DMGR and ConsoleServer
Points to remember – BWM Setup
BWM and S9 Integration
- BWM server can only be installed on Websphere 7.0.0.15
- In WAS Configuration file all the paths specified should always have forward slash
- In WAS configuration file Nodename , cell name are case sensitive.
- When B WM server is configured to work with S9 deployment , you need to configure the JV M property on V MGR → L ink
***IMPORTANT - This property should not be present when BWM is not used.
Steps to stop using BWM in existing AV deployment
If you are facing some issues due to BWM server and want to stop using it so that normal AV deployment can function properly you need to
follow below steps. Note that just stopping BWM server will not suffice since SIP PR will be still routing all SIP requests to BWM server.
--> Login ssc admin console and navigate to SIP PR admin page. Go to proxy administration tab and delete all the routing rules that are
configured for BWM.
Please make sure that you perform this task via admin page only to avoid any corruption. As of now there is no option to disable routing
rules so you will
--> In case of S9 deployment , login to VMGR admin console and remove the JVM property that was added to configure VMGR as outbound
proxy. → Link
When you want to bring back BWM , redo the configuration removed in above steps.

Symptoms and Corrective Measures
37
Symptom
Possible Reason
Corrective Action
N-Way and Meetings AV calls not working. User receives
dialling error with reason “403 Forbidden” error
VMGR sends this error since DNS
mapping of VMGR hostname is not
done correctly.
VMGR must not be deployed on Internet
/ Public Network.
VMGR does not honor hosts file and
gives preference to hostname mapping
done in DNS. So if VMGR is installed on
public network, DNS lookup needs to be
disabled.
VMC U not starting up
Hardware configuration does not meet
minimum requirement
Machine must have 4 C ore, 8 GB R AM
and 50 G B R AM at a minimum for a
Pilot deployment spec
VMC U installation failed
- OS is not supported.
- mcms or apache user not created
- one or more Prereq rpms are missing
Must be R HE L 5.8+ or S US E 11,
S P2/S P3
Install VMC U as "root" and not with
sudo.
Make sure the list of prereq rpms are
installed.
MC U not connecting to DMA
Network Interface on VMC U is not
"eth0"
Make sure eth0 is the only interface (in
addition to loopback, lo). R einstall the
VMC U.
User receives the following error..
“An error has occurred.
com.ibm.mediaserver.dma.tcspi.exception.RESTApiExc
eption: HTTP response '409: Conflict
Inaccessible subscription consumer URL . Detail: HTTPS
GE T request returned 404.
VMGR is not able to communicate with
CF over Https port of CF
1. Check if CF cert is imported in VMGR
truststore
2. Check if CF https port exists in its
Virtual host - default_host
38
Symptom
Possible Reason Corrective Action
AV is not enabled for user
SIP REGISTER request sent by
client receives 403 forbidden
error.
SSO between community and
media server is missing
Security role settings on SIP PR application is not configured correctly.
Follow the link
In n-way or meetings Video call,
C oninuous P resence is not seen
VMGR /C F configuration may be
incorrect which causes issue in
the S IP S UBS C R IBE requests.
- Make sure the C F S IP Port number is correct in the stavconfig.xml
file. The value should be same as what is listed as S IP DE FAULT
HOS T or S IP DE FAULT HOS T S E C UR E in Ports List of Media S erver
depending on the TC P or TLS configuration.
<configuration lastUpdated="1226425838277"
name="C onferenceS erverP ort" value="<Put the correct port value
here.>"/>
- In addition F or C lustered environment, Add F QDN of WAS Proxy
fronting P R cluster or LB VIP in S IP PR 's Domain List. T hese entries
need to be made in Handled Domains section on S IP PR admin page
on S S C
C all is not working after VMG R
machine is restarted.
S olid DB is not started on VMGR
machine restart .
P lease deploy S olidDB init start up script on VMG R machine , so that
S olidb db is started before VMGR during restart/reboot of VMGR
machine. Technote information will be updated soon.
BWM installation fails in case of
BWM cluster environment with
multiple WAS proxy servers
BWM installer not capable of
handling more that one WAS
proxy servers
DB C orrupted, Values in property
files are incorrect
HotF ix- SJHA-9F8E GA needs to be installed before BWM installation begins
Remove WAS profile , Drop the DB , review all the values in the property files
and re-run the script
If you successfully get AV service provider listed on client , then
possible reason for unauthorized error could be missing SSO
configuration between Media and Community server.
Symptom
Possible Reason Corrective Action
Turn is not working for external and
internal calls when Turn machine is
multi homed with public and private
IP and internal clients can't reach
public IP and external client's can't
reach internal IP.
Incorrect entries in Turn server
properties file.
1. Correct TurnSever.properties file entries as below
a. turn.local.hostname.ipv4=<Put here public IP of Turn server
mahcine>
b. turn.allocation.hostname.ipv4=<Put internal IP of Turn server
machine>
c. turn.allocation.hostname.ipv4=<Keep this blank>
2. Make sure internal clients start in non ICE mode by making sure they
resolve Turn host name to 0.0.0.0
3. Restart Turn server.
Turn is not working for external and
internal calls when fronted by router
or firewall for external access.
39
1. F irewall blocking 3478 port.
2.In TurnS erver.properties file ,
public IP is mentioned as
F irewall or router IP.
3. On firewall/router mapping to
Turn machine's public/private IP
(where Turn server is listening )
is not present.
1. Make sure port 3478 is open on F irewall.
2. Verify TurnS ever.properties file entries as below
a. turn.local.hostname.ipv4=<Put here public IP of Turn server
mahcine>
b. turn.allocation.hostname.ipv4=<Put internal IP of Turn server
machine>
c. turn.allocation.hostname.ipv4=<Keep this blank>
3. On firewall / router , make sure there is mapping to forward the
request for Turn to IP:port where Turn is listening.

Install Media server in a multihomed environment
–
In case Media manager is to be installed on machine with multiple IP addresses , Media server should always have
primary hostname of the machine assigned to it .
–
In case primary hostname is not used during installation of Media server then we need to put actual hostname in
