Fiber Optics Questions
Is there a SDTV fiber connection?
No. But you convert from SD-SDI to optical using 6800+ modular products.
It is possible to change fiber connectors in the field?
No. The fiber connectors must be provided at time of order.
What fiber connectors are available?
SC as standard and FC (X75OPT-FIBER-FC) and ST (X75OPTFIBER-ST).
What is fiber wavelength on the input/output of the HDTV option?
Input: 1200 to 1600 nm.
Output: 1310nm
Streaming, Compressed and Metadata Questions
How does the X75 handle closed captioning?
During upconversion, the X75HD processes the EIA-608 data on line 21 in the input SDTV signal and
“transcodes” it into EIA-708 on line 9 of the output HDTV signal. A reverse processes occurs for
downconversion. For cross conversion, CC is passed through in a transparent manner.
Can the X75 provide an EIA-708 output on the data port during upconversion so that closed captioning can
be passed to an MPEG coder?
Yes, this is a software key option. Contact Product Management for more details.
How do we do streaming via the X75HD?
The X75 has a web server with control, monitoring and thumbnail streaming. A video only
“thumbnail” which is monitoring quality is included for free and is to be used with a web browser
connected to a
X75 . The primary Ethernet port is used for this capability. The thumbnail is sent to the
web browser, one frame every few seconds.
There is a plug-in option for video and audio streaming on the secondary Ethernet port that is
monitoring quality. This is not MPEG4.1, AVC, AVI, JVT, MPEG4 Part 10 (H.264) or SMPTE VC-1
(WM9 or Windows Media 9). We are using MPEG4; however, it is low bitrate with full motion, and is
meant for monitoring purposes, and not for “broadcasting” purposes. The streamed image is 1/4 VGA
in size. QuickTime can be used to view the signal.
Does the X75 support MPEG 2 for ATSC or DVB-ASI?
No. Broadcast compressed video is not supported at this time.
Does the X75 have ASI input and output?
No. ASI is the Asynchronous Interface that carries one or more compressed program streams. The
X75 does not support compressed video for broadcast purposes at this time.
What algorithm will be used for the streaming video/audio?
The unit will be compatible with QuickTime and Windows Media Player.
