Q: Can the product support 10Mbps or 1Gbps?
A: No, only 100Mbps 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 L300 device in real time, completely transparent to
the end user.
Q: If a customer wants to publish video content optimized for the L300, 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 L300 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 L300, 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.
