Multicast Stream – Tandberg MXP 990

Make sure that the PC is connected to the same LAN (or multi-cast enabled WAN) as the codec that is to be streaming

Note: The entire configuration related to my IP settings are erased or replaced with ‘X’. Please let me know if you face any problem, and keep following @ahsantasneem for more

Step 1: Static Public IP assignment, entering in all the IP fields for address, subnet mask, and gateway and DNS.

Step 2: Go to Endpoint Confiuration -> Streaming

Address: is defined as the IP-address of a streaming client, streaming server or a multicast address. Giving an address in the range 224.0.0.1-239.255.255.255 will broadcast the stream to any host that has joined the specified multicast group. Specifying normal broadcast address 255.255.255.255 will broadcast to any members on the LAN.

Address Port: If several codec’s are streaming to the same IP-address, different ports have to be used in order for the client to know which stream to receive. In this case 22232

Source -> Auto: Enables streaming of both local and far end video. Selection of which site to be streamed is done using voice switching (the site that speaks is streamed).

Streaming Password : Set password so that only participants entering correct password will be able to view the streaming session. Entering a password will prevent unauthorized people from accessing the streaming session

Step 3: Click -> Overview -> Streaming and press the link “Start Streaming” to start the stream.

A new webpage is opened with the streaming view displayed within the page. You can also open your web-browser directly to the streaming page by entering this URL into the browser(In this case): http://124.x.x.x/stream.sdp where 124.x.x.x would be the IP of your streaming device (Tandberg mxp 990). If a streaming client is successfully installed on the computer, a window will start up and soon show the incoming streamed information as shown below:

Step 4: To receive the stream directly from within QuickTime Player, launch QuickTime

player, and under the File Menu select ‘Open URL’ and enter http://124.x.x.x/stream.sdp where 124.x.x.x would be the IP of your codec.

SDP file

When streaming, the codec will generate a SDP file 'stream.sdp' which can be retrieved through the codecs web-interface (by http). This file describes what type of media is used (G.711 / H.261) and which (multicast or unicast) address the streaming is sent to. The clients (QuickTime and RealPlayer) use this information to listen for the stream.

Step 5: To end the streaming session, just press the “Disconnect Call” button on remote control or click the ‘Stop Streaming’ icon on the web page provided the ‘Allow Remote Start’ is set to on.

Note: That just closing the web application will not end the streaming session, as other codec’s still might be able to receive the streamed information.

Supported Streaming clients

Cisco IP/TV, QuickTime version 4 or greater, RealPlayer version 7 and VIC

Cisco IP/TV http://www.cisco.com

QuickTime version 42 or greater http://quicktime.apple.com

VIC http://www-mice.cs.ucl.ac.uk/multimedia/software/vic/

New Facebook 'Groups' Designed to Completely Change the Way You Use Facebook

Facebook has just revealed a new version of Groups at its live press conference in Palo Alto, California. Facebook Groups are a shared space where members can participate in communal activities like group chat, e-mail lists, document sharing and group photo-tagging.

The new Groups product was built from the ground up; Facebook Founder and CEO Mark Zuckerberg says Groups is an entirely new product that only shares the name in common with the old Groups functionality. The old Groups will continue to remain in place, but moving forward members will only be able to create new Groups.

Groups are closed by default (but can be secret or open) and are designed to be spaces where small groups of friends share information, with each group controlled by the entirety of its members — an important new direction for Facebook. The group chat feature is just as it sounds; members can participate in back-and-forth IM conversations with everyone in the group at the same time.

Once you start participating in Groups, the most-viewed ones will automatically live in the left-hand navigation of the page for easier access.

Facebook has also released a mobile interface and an Open Graph API for Groups, which means that soon Facebook Groups will be accessible in all imaginable capacities.

With everyone in control, Groups will function much differently than before. Facebook asserts that social norms will govern activity. Ultimately, the company believes the new Groups will fundamentally change the way you use Facebook and give you more control over the distribution of your messages.

From our initial tests, we can assert that Groups is, as Zuckerberg promises, something “so simple that everyone on the site will want to interact with it.” And, by design, everyone will use it.

As Facebook clearly stated during the press event, its goals are to map all real-world groups, to ensure that everyone participates and to build something useful in lots of contexts. What this really means is that Facebook wants to fully understand member relationships (an extension of its Open Graph undertaking), and that the company will use your behavior in Groups to better understand these relationships.
