Flash Media Server 4 brings Multicast to Flash Video

In case you missed it Adobe announced Flash Media Server 4 . This is a significant release for a number of reasons. The first reason is that many corporate customers have been interested in Flash video but were not able to take advantage of it with out support for IP Multicast as this technology was a mandate from their IT organization. In other words this update for the Flash Media Server to version four gets you a 64bit architecture, Absolute timecode, faster seeking, trick mode playback (fast motion, slow motion, and frame stepping), intelligent reconnect, faster switching for RTMP Dynamic Streaming and IP Multicast Support.

Using version 4  of the interactive edition of the Flash Media Server gets you the ability to choose between Unicast (with or with out Origin / Edge), IP Multicast and even Live HTTP Dynamic Streaming. It is even possible to failover from IP Multicast to a Unicast stream if necessary. When you consider all of the possibilities they include:

  • Interactive applications that support video, audio and data for one to many and many to many for both live and video on demand
  • Large scale broadcasts using IP Multicast
  • Origin / Edge solutions that can be used to intelligently reduce bandwidth requirements for vod
  • Failover for complex environments with different network requirements (e.g. remote sites, vpn)

That is a short summary of the possibilities that you get with the interactive edition of the Flash Media Server but that was not the only announcement. Adobe also announced Adobe® Flash® Media Enterprise Server 4. If you are not familiar with RTMFP that would be a good place to start. This peer protocol will allow you to take advantage of users / viewers upstream bandwidth to broadcast video, audio and data in your application and now the Flash® Media Enterprise Server 4 can participate in those groups. So consider the limitations of a peer broadcast. First you will only have access to the one video codec that can encode that is part of the Flash Player and that is Sorenson Spark. If you are familiar with Sorenson Spark you know that the quality leaves something to be desired. When you consider that the Flash® Media Enterprise Server 4 can act as a peer using RTMFP you now have access to all of the varied video formats that can be broadcast using the server (On2, H.264,…). It is also important to note that you are not limited to just video when you are using Peer Assisted Multicast (RTMFP) you can include data as well. These applications can include interactivity unlike IP Multicast. Of course there are considerations that include additional latency based on the number and location of peers in a group but the possibilities are amazing. Just consider an internet based application that includes video and interactivity with 10k concurrent users. With out a peer solution you would have to invest in a significant number of servers as well as a significant amount of bandwidth. With the Flash® Media Enterprise Server 4 you could address both server and bandwidth requirements with a small fraction of what it would take with a Unicast solution. The cost savings will be significant.
