Media Types Supported
The following media types are supported:
• MPEG-2 Video Files (aka “VOB” or “MPG” files) - These are the same
types of files that are found on DVDs. They can be authored using any video
editing software such as Pinnacle Studio or iMovie. Video sizes up to 1080i
(1920x1080 interlaced) are supported with bit rates up to 25Mbps on the HD2000,
and sizes up to D1 (720 x 480) are supported with bit rates up to 9 mbps on the
HD600. When a video is played, it will be scaled in real time to the output
resolution (which can be much higher definition). The files must contain program
streams (transport streams are not supported. Files for the HD600 must have an
audio track, and the sampling rate for the audio must be 48K. An audio track is
not required in files for the HD2000.
• 8, 24, 32 bit .BMP files - These can be authored using almost any paint
software such as Adobe PhotoShop, Macromedia Firefly, or even “Paint”, which
comes with Windows. Any digital camera image can be saved in or converted to
this format. A variety of resolutions are supported, up to 1024x768 if outputting
via VGA, or 1280x720 (720p) if outputting via “Component”.
• PNG files (HD2000 only)
• MP3 audio files – Currently these must be stereo or mono. The HD600
supports files sampled at 48KHZ, while the HD2000 supports files sampled at
either 44.1KHZ or 48KHZ. BrightSign has no sample rate conversion. Certain
USB speakers only support 48KHz sample rate – when using a USB speaker with
this characteristic, all audio will be output at this rate regardless of the sample rate
it was recorded at.
• Dolby Digital (AC3) 5.1 audio in a video file
o BrightSign supports 5.1 AC3 audio playback out of USB (HD600 only),
SPDIF, HDMI (HD2000 only) and analog outputs (HD600 only). For the
USB and analog outputs, the AC3 audio is decoded to PCM within
BrightSign. This results in 6 tracks over a single USB connector, or three
stereo analog connectors. For SPDIF the AC3 audio is sent in its
compressed state to the SPDIF receiver. There is also an option within the
script control to automatically mix-down the AC3 5.1 audio to stereo
PCM.
