Developer Network live broadcasts

By: John Kaster

Abstract: Read this to get instructions for attending our various live chat broadcasts

    Watching the CodeRage streams and asking questions

We have a new event chat room interface we are introducing for the first time at CodeRage. The live media stream for each session in each track is embedded into the chat room for that session.

Except for the general sessions, CodeRage has two broadcasts going at the same time. Each broadcast stream (or channel, if you prefer) has its own "event chat" room, where you can ask questions of the speakers or moderators, and chat with other people attending. You will need a media player that supports viewing WMV files to watch or listen to the broadcast. Javascript also needs to be enabled for the AJAX-powered Chatjet rooms. We have tested the chat interface with FireFox, Opera, and Internet Explorer 6 and 7, and Windows Media player 8, 9, 10 and 11.

The first time you enter an event chat room, you will have an opportunity to create your chat room account. This chat room is linked to your Developer Network Membership account, so once you set up your chat account, you will not need to login again. When you go to the chat room, if you do not have your user cookie set for the Developer Network, you will be redirected to the login page for your membership account.

We encourage you to go to the chat rooms now so you can address any access issues you might have before the event starts. The streams may be up or down sporadically, but will usually be running from now throughout the end of CodeRage.

    Stream 1

For sessions in "stream 1", open http://eventchat.codegear.com/chat?action=codegearlogin&room=event1 to use the chat room for watching and chatting.

Due to bandwidth load, we are now using Interwise for audio and video for the broadcasts. You will need to download and install a client, but there is a java-based client and a Windows client, so you can take your pick.

We are still taking questions via the chat room, however, not through Interwise. To load the Interwise room for both audio and video, go to http://borland.interwise.com/borland/iSeminar/PJ8838.

If you want to listen to the audio from our media server instead of through Interwise, use mms://video.codegear.com/stream1.

General sessions will be in stream 1. Whenever a general session is going, be sure to open the stream 1 chat room.

    Stream 2

For sessions in "stream 2", open http://eventchat.codegear.com/chat?action=codegearlogin&room=event2.

Due to bandwidth load, we are now using Interwise for audio and video for the broadcasts. You will need to download and install a client, but there is a java-based client and a Windows client, so you can take your pick.

We are still taking questions via the chat room, however, not through Interwise. To load the Interwise room for both audio and video, go to http://borland.interwise.com/borland/iSeminar/JR8382.

If you want to listen to the audio from our media server instead of through Interwise, use mms://video.codegear.com/stream2.

    Watching and listening

For CodeRage, due to bandwidth issues we are currently streaming audio only from the chat room. For other broadcasts, in Internet Explorer, the event chat room will show the complete video scaled to fit in a small window. You can use the "Detach video" button to display the stream in a separate window to resize it.

If you are using a non-Microsoft browser and Windows Media Player 11, you may notice that the video is cropped. You will need to use the "Detach video" button to display the stream in a separate window to see all of it. The detached video window will allow you to resize the video stream to whatever size you wish.

Please note: once you detach the video from the chat room, there is currently no way to re-attach it. If you want the video embedded back in the chat window, you will need to leave the chat room and come back in.

    Replays of sessions

After CodeRage completes, we will make all the sessions available for replay, so you can watch them whenever you want. Thanks for your interest!

    Audio problems

A fair number of users have reported problems with Interwise audio. Unfortunately, Interwise audio cannot be turned off in the client, although there are dialogs that seem to indicate it can be. The solutions we have found thus far are:

  1. Use two machines: one for Interwise video and one for our mms stream audio.
  1. Windows Vista allows you to individually control audio settings for each application using audio. So if you're using Windows vista, you should be able to turn off audio on Interwise and use media player to listen to our audio streams.
  1. Use IndieVolume to individually control the volume of Interwise and your media server stream. http://www.indievolume.com/download.php

Connect to either mms://video.codegear.com/stream1 or mms://video.codegear.com/stream2 to hear our audio streams.

    How to Register for Promotional Offers and Prizes

There is a 'button" link in the event chat rooms that says "I'm Listening". Click on that button during the broadcast to indicate that you are listening. If you have not registered in the LiveCast application, you will be prompted to do so when you first click the link. It is pretty painless.

For CodeRage, we will be awarding a variety of prizes for both sessions and the entire CodeRage conference, so be sure to click "I'm listening" at least once for every session you attend.

For some of our other broadcasts, we also provide prizes. For every chat you register as a listener, you will also earn points.

If you do not want to participate in the chat rooms, you can go directly to the home page for LiveCast at http://test.codegear.com/livecast and select the appropriate broadcast from there.

    Chat room actions

There are many actions available in our chat room. You can enter them in the same edit box where you post your messages. Here are some of the more common chat actions.

/ask

Ask a question

Example:

/ask Is this a good question?

/me

Say you're doing something

Example:

/me will be right back

/msg

"Whisper" to another user

Example:

/msg username How long have you been here?

/url

Insert a URL into the chat

Example:

/url http://dn.codegear.com

    Troubleshooting Connectivity Problems

If you want to test your connectivity to our live broadcasting system, open your media player using mms://video.codegear.com/replay/cdntvtest.wmv. If you have trouble watching this replay, try setting the buffer on Windows Media Player to 20 seconds. You can also manually set your connection speed lower or higher. It's under the Tools | Options | Performance dialog, shown here:

If you can't connect to this replay at all, you probably have port 1755 (Windows Media Server) blocked on your firewall, or port 554. You'll need to get those ports opened. If you can't open the firewall port yourself, you'll have to request it from your IS department. We hope to "see" you on the broadcast!

    Schedule of live chats

EventCentral lists all scheduled live chats. You can see this list by setting your EventCentral filter to upcoming events and "live chat". You can also use this link to see the list of upcoming live chats, then filter it to the product(s) you are interested in hearing

    Watching or Listening to chat replays

All chat replays are available from the CodeGear TV home page.
