General restrictions
• The maximum size of any multimedia file should never exceed 4Gbyte.
• Do not use a dot “.” in folder naming.
• The minimum bitrate for ALL video streams formats is 256kbps. Any stream with a bitrate lower than
256kbps can result in visual artifacts and stopping video.
• The maximum bitrate for streaming content (audio & video) can be restricted by the bandwidth of
your local wired or wireless network.The bandwidth (performance) of your PC or USB device can
also limit the maximum bandwidth available for streaming.The numbers in the tables above are only an
indication of the maxima as defined by the TV system connected through a wired Ethernet
connection.
• If video streams are supporting multiple audio tracks the first audio track will automatically be
selected, the other audio tracks can’t be selected.
• External subtitle files (e.g. DivX.srt subtitle files) are not supported.
Network related restrictions
• The length of a filename, including the directory path, should not exceed 500 characters for network
(PC) based content.
• The maximum bitrate for streaming content (audio and video) can be restricted by the bandwidth of
your local wired or wireless network.The bandwidth (performance) of your PC or USB device can
also limit the maximum bandwidth available for streaming.The numbers in the tables above are only an
indication of the maxima as defined by the TV system connected through a wired Ethernet
connection.
