Are the Merlin HDProducer and Merlin HDDirector still valid products?

Uncategorized — Administrator @ 6:54 pm

Skymicro still carries its PCI-X related products, the MerlinHD/Producer and MerlinHD/Director, but as OEM products only.   Firmware, drivers and supplied applications are frozen at current release levels.

How Do I generate a test pattern output on a MerlinIP card?

MerlinIP,Uncategorized — Administrator @ 6:50 pm
To generate the test pattern, run an application that initializes the board and then run the mwr program in a command window.  Type mwr -b1 0xe0022c 0xa000?000 where ? can be 0,2,4,6,8,a,c for 720p60, 1080p24, 1080p25, 1080p30, 1080i50, 1080i60, 1080psF24.
The mwr program allows you to write a specific value into a specific register on the Merlin board.

How do Skymicro’s HD and SD products support AFD?

Uncategorized — Administrator @ 6:49 pm
In the Merlin05, the AFD information is carried in the signal encoded when the 4:2:2  frame is captured.  The AFD information is not interpreted, but BRec does provide the capability to insert an AFD value into the MPEG-2 file.
On the Merlin HD/Director and MerlinIP boards, the information is carried in the VANC. Again it is captured in the video signal, but not interpreted.   It seems unusual that someone would want an aspect ratio other than 16:9 in an HD stream.

What version of firmware do you recommend for the Merlin 05?

Merlin05,Uncategorized — Administrator @ 6:48 pm

The Merlin05 uses firmware specific to the board.  There are two fpga chips on the Merlin05 board named f1 and f2.  The fpga code in the f1 chip is initialized when power is applied to the board and the code is loaded into the board using the merlin.exe program.  The filename for the current release of the f1 code is merlin05f1.hex.91.hex and the current modified date for that file is 4/2/2007.

The f2 chip is loaded with the microcode and the microcode is initialized under application control.    In the BRec application, this is done during program initialization; the blue progress bar incrementing across the bottom of the splash screen tracks the firmware load process.  The current f2 firmware for the the Merlin05 is in a file named Merlin05f2.hex.91 and its modified date is 2/8/2010.

Does the Merlin05 pass the incoming video and audio output signals to the SDI outputs on the board?

Merlin05,Uncategorized — Administrator @ 6:45 pm

The video signal that is coming into a Merlin05 board is routed to the SDI outputs of the board.  The incoming signal that is used (Composite, S-Video, etc.) is determined by the register settings on the board, which determine which of the video inputs is active.  Audio signals  are controlled by the audio routing function, which allows the audio from any source to be routed to any output channel.  The BRec audio router serves as a good example of an application implementation of the Merlin05 board’s audio routing functionality (menu item Audio/Audio Router).

Is there a list of examples for applications using different models of Xilinx chips on MerlinIP boards?

MerlinIP,Uncategorized — Administrator @ 5:37 pm

Currently, most applications using the MerlinIP and MerlinIP-B boards can be run using the Virtex-5 110 chip.  JPEG-2K codecs require a 220 or 330 model chip, depending on what resolution video is being processed.

Vsoft AVCi codecs will run on the 110 chip at 1080i resolution.

For estimating the amount of processing available on these chips for custom applications, capacity requirements for the application would need to be merged with the resources currently used on the chip for board-related processing.    Skymicro can assist with these estimation activities along with determining what integration tasks must be accomplished.

What are the different MerlinIP Xilinx processors for?

Uncategorized — Administrator @ 5:35 pm

The MerlinIP uses the Xilinx Virtex-5 FPGA chips.   Currently supported models are the 110, 220 and 330 LXT; higher model chips have additional capacity and higher cost.

The 110 chip is used in the basic MerlinIP and MerlinIP-B cards.  The Skymicro-supplied firmware module provided for the 110 based card provides the basic functions of the card and other services, such as color space conversion.  The 110 chip will also run the Vsoft AVCi 50/100 codec at 1080i.

The 220 and 330 chips are used for advanced processing which require the additional capacity available.  For example, Intopix JPEG-2k codecs use either 220 or 330 chips, depending on the video resolution.
