Q: Can the product support 10 Mbps or 1 Gbps?
A: No, only 100 Mbps is supported.
Q: What is transcoding?
A: Transcoding is the process of converting media formats from one type to another. This is a
common technique used when wanting to optimize video for a given player or device. For instance,
you may transcode some video to play on a mobile phone. vSpace has an efficient transcoding
engine that converts video into a stream that can be locally decoded and displayed on the FUTRO
DC20-1 in real time, completely transparent to the end user.
Q: If a customer wants to publish video content optimized for the FUTRO DC20-1, what format is best?
A: Original content up to standard DVD resolution (D1 - 720x480) will have the best playback
experience. Content may be encoded in many codecs, but if being distributed over the web, high
compression H.264 or MPEG4 delivers small file sizes, but if size is not an issue, lower compression
formats such as MPEG2 require less processing on the server. Please create a test clip in one
of the supported formats mentioned in the Multimedia section and test it on your intended video player.
Q: The accelerated multimedia feature of the FUTRO DC20-1 sounds like simple
multimedia redirection. How is this different?
A: Multimedia redirection found in terminal server products from Microsoft or Citrix simply send the
entire media file over the network to be played by the client. This means that the client must have
a full media player software stack and the necessary codecs to decode those files. This means
that to achieve the same quality of video as the FUTRO DC20-1, a thin client must be 2-3X more
expensive and require painful management of the local software stack to constantly ensure that
codecs are loaded. Typically, this means the device needs to be similar to a full PC.
