Sony CRV

The Sony CRV disk recorder can be directly controlled from your workstation without using an intermediate video controlling device. It is connected to your workstation via an RS-232 port.

Even though it is possible to control the Sony CRV with a separate animation controller, we recommend that you use direct RS-232 control, as this driver is optimized for both the CRV and applications.

Syntax

The syntax is:

device video controller name
          server_name server
          server_id socket
          server_host host
          buffer buffer
          display display
          defn
                    format format
                    ttydev device
          enddefn
enddevice
device video controller name

The name is the name you want to assign to this device.

server_name server

The server is the name of the executable that controls the Sony CRV. It resides in the product_bin. The server should be vtcsonycrv for the Sony CRV. (If you relocate the server executable, or if the server is running on a different host than your application, you must specify the server as a full UNIX pathname.)

server_id socket

The socket is the socket number through which your application communicates with the Sony CRV server process. This number must be unique to your UNIX system for each defined device and (Alias|Wavefront and non-Alias|Wavefront) server process. Configurations referring to different Sony CRV recorders must use different socket numbers.

server_host host

The host is the name of the workstation to which your Sony CRV is connected. This is typically the workstation on which you are running your application, but can be any of the workstations on your Ethernet network. If you are using one workstation for your application and another for the Sony CRV, you must install your application on both machines. The host can be localhost if the Sony CRV is connected to your workstation.

buffer buffer

The buffer is optionally used to specify the name of a frame buffer device that is related to the Sony CRV device being configured. If defined, this corresponding frame buffer is opened whenever the Sony CRV device is opened.

display display

The display entry is optionally used to specify how you want the disk location to be displayed. The default, timecode, displays disk locations using time code. To display disk locations as frame numbers, specify frame.

Device-specific statements

format format

The format indicates whether your Sony CRV recognizes NTSC or PAL video. If this line is omitted, NTSC is used by default.

ttydev device

The device indicates the name of the UNIX device port through which the workstation communicates with the Sony CRV. On SGI workstations, it is typically ttyd1, ttyd2, ttyd3, or ttyd4, which corresponds to the RS-232 ports on the back of the computer. For more information, see appendix A, "Connecting RS-232 Devices."
