Web Streaming Instructions & Best Practices

Software Requirements:

  1. Windows XP Users who would like to view the stream may use Windows Media Player version 11 available from Microsoft.  Windows Media Player version 11 can be downloaded at: http://www.microsoft.com/windows/windowsmedia/player/11/default.aspx
  2. Mac OS X Users who would like to view the stream may use Windows Media Player version 9 for Mac available from Microsoft.  Windows Media Player version 9 for Mac OS X can be downloaded at:http://www.microsoft.com/windows/windowsmedia/player/mac/mp9/default.aspx  

Supported operating systems:

  1. MS Windows
  2. Mac OS 10.3 or higher

Other requirements:

  1. IHETS Interactive requires a broadband Internet connection. Most consumer-grade DSL or cable Internet services offer sufficient bandwidth for home users. A T1 or better is required for school campuses.
  2. Dial-up Internet access is not supported.
  3. Please disable all screen savers and power-saving settings.
  4. Please disable all pop-up blockers prior to joining the stream.

Viewing Site Configuration

Many participating schools will find that they can only accommodate one login to the Web streaming connection at a time due to bandwidth limitations. Therefore, if a school has scheduled two classes or more to participate in a Purdue zipTrip at the same time, we recommend that a single computer be used in a larger location at the school. We recommend using an auditorium room setting with a projector and sound speakers for this purpose. Please log on at least 15 minutes before the start of the event. Please note that a high-speed Internet connection is required. Dial-up Web access is not supported.

Testing

Please run a system test in the days preceding the event to verify system compatibility and correct network configuration. To test your operating system and network security settings, contact IT@P BNS Streaming Services at (765) 496-6113 or (765) 494-1032.

Connecting to Live Show

Register/log in to this website and download the 'Connecting to the LIVE Show' guide for the streaming URL.

Interacting during Live Show

All interaction will be handled via email. Please have a second computer with Internet access available for sending e-mail to the Purdue zipTrips host and scientists. Questions and comments can be submitted to ziptrips@purdue.edu. The host or scientists will then answer some of those questions during the live show. Basic instructions will be provided at the start of the session.

Getting Help

If you have questions, contact IT@P BNS Streaming Services directly at (765) 496-6113 or (765) 494-1032.

Video Conference Instructions & Best Practices

Types of supported video conferencing endpoints (video codecs):

  1. Polycom
  2. LifeSize
  3. Tandberg

Viewing Site Configuration

Many participating schools will find that they can only accommodate one video conferencing connection at a time due to bandwidth limitations. Therefore, if a school has scheduled two or more classes to participate in a Purdue zipTrip at the same time, we recommend that a single video codec be used in a larger location at the school. We recommend using an auditorium room setting with a projector and sound speakers for this purpose. Please join the conference at least 15 minutes before the start of the event.

Testing and Certification

Testing video conference endpoints prior to a conference is very important. IHETS offers a certification process to verify the connectivity and quality of your video conferencing endpoint. The certification process includes:

  1. Testing point-to-point calls
  2. Testing MCU Calls
  3. Registering site's endpoint with IHETS gatekeeper
  4. Insuring that local firewall is setup to handle video-conferencing traffic

To certify and test your video codec endpoint and network security settings, contact the IHETS Help Desk at (317) 263-8999 or (800) 246-7615 (toll free), or via e-mail at helpdesk@ihets.org. This certification must be completed one week prior to the Purdue zipTrips live show.

Network Security Settings:

  1. Ensure that all network switches in the IP video path are set to 100 mbps and full duplex.
  2. All cables between Ethernet devices must be at least Category 5.
  3. Avoid cable lengths of more than 300 feet (100 meters) on any Ethernet segment. If a segment requires more than 300 feet, we recommend a fiber connection between the switch and codec. A fiber-to-copper converter can be used to terminate the connection to the codec.
  4. Using a repeater will negatively impact quality by inducing latency (delay) into the video conferencing stream. Multiple repeaters will multiply the amount of latency in the video conferencing stream. Therefore, we recommend that repeaters not be used.
  5. Do not use a 10 mbps or half-duplex hub (switch). As a shared device, a hub will split the available bandwidth to connected devices, decreasing bandwidth to the codec.
  6. Ensure that the NIC card is set to 100 mbps / full duplex (PC) before moving IP desktop or room system codecs from one location to another. If the codec is an appliance, make sure the connecting port is also set to 100 mbps / full duplex.

Connecting to Live Show

IHETS will provide a dial-in number for those sites certified and registered with the IHETS bridge. We can also dial out to your IP address, if needed.

Please complete the following steps up to 30 minutes before the event begins:

Dial-in instructions:

  1. Have your video codec connected and registered with the IHETS gatekeeper.
  2. Using your video codec remote control, dial in to the phone number provided after registration.
  3. You should hear music 15 minutes before the event begins.

Dial-out instructions:

  1. Have your video codec connected and registered with the IHETS gatekeeper.
  2. IHETS video conference bridge will call and connect your video codec to the bridge. Make sure auto answer is enabled on your video codec.
  3. You should hear music 15 minutes before the event begins.
