Conversion between HD/SD-SDI and HDV/DV

The VC-50HD provides a compact solution for converting between high-quality uncompressed HD/SD-SDI video and the HDV/DV video widely used by video devices. It allows a camera or deck with SDI input and output connectors to be connected to an HDV/DV device with IEEE 1394 (i.LINK) connectors, enabling high-quality image conversion regardless of which device is the source.

High-quality conversion of MPEG-2 TS (35 Mbps/50 Mbps)

When receiving an HD/SD-SDI input and sending it from IEEE 1394, the signal can be converted not only to HDV/DV but also to MPEG-2 TS 35 Mbps or 50 Mbps. This capability allows recording with even better quality than 25 Mbps HDV/DV. You can take your laptop computer or an F-1 (version 2 or later) to the shooting location, and capture high-quality video for online use at the same time that you're shooting. Of course, conversion from MPEG-2 TS to SDI is also supported.

Three-way power supply support

In addition to the AC adaptor, the VC-50HD can be powered from an external battery or from AA batteries, allowing use in a variety of situations. AA batteries installed in the internal battery case will operate as a backup power supply. This allows the unit to continue operating seamlessly even if the AC adaptor should become unplugged or if the external battery is replaced.

Compact and tough body

Like the F-1, the VC-50HD is designed for use in the field (Field Oriented Design). Its compact and tough design ensures that it can be used reliably in rugged conditions.

Provides a low-cost monitoring environment

An HDMI output connector is provided on the VC-50HD's front panel. This can be connected to a computer display or TV monitor, providing a low-cost monitoring environment.

* MMP (Moore Microprocessor Portfolio) refers to a patent portfolio concerned with microprocessor architecture, which was developed by Technology Properties Limited (TPL). Roland has licensed this technology from the TPL Group.
* IDX and ENDURA are registered trademarks of IDX Company, Ltd.
* Anton Bauer is registered trademark of Anton/Bauser, Inc.

The VC-50HD's conversion capabilities

The format of the input to the VC-50HD is detected automatically. The VC-50HD is capable of performing conversions in either direction (SDI to IEEE 1394 and IEEE 1394 to SDI). The formats that can be converted and output are shown below.

SDI IEEE 1994
HD-SDI	1080/59.94i1080/50i720/59.94p720/50p	HDV
		35Mbps MPEG-2 TS
		50Mbps MPEG-2 TS
SD-SDI 480/59.94i(NTSC)576/50i(PAL)		DV
		9Mbps MPEG-2 TS
		12Mbps MPEG-2 TS

* The VC-50HD does not support up/down-conversion, I/P conversion, or frame rate conversion.
* If you select MPEG-2 TS as the IEEE 1394 output, and input SD-SDI, the bit rate will be approximately one quarter of what it is when HD-SDI is input.

Names of things and what they do

A fully charged ENDURA-10 (E-10) made by the IDX Company, Ltd. will provide approximately ten hours of continuous operation.

* The continuous operating time will depend on the temperature and other conditions of use.

Turning the power on

After you have made connections correctly, you must turn on the power as described below. Incorrect operation may cause malfunctions or may damage the speakers of your monitoring system.

* Due to a circuitry-protection feature, the VC-50HD requires a few moments after it has been powered up before it is ready for normal operation.
* If you are operating the unit only on AA batteries, the POWER indicator will blink when the batteries run low. Replace the batteries as soon as possible.

On the side of the VC-50HD, slide the POWER switch in the direction of the arrow and hold it for two or three seconds until the POWER indicator lights.

If mode select switch 6 is on, so that remote control is activated, the VC-50HD's power will automatically be turned on when power is supplied at DC IN. In this case, the POWER switch is disabled. However, the power will not turn on automatically if you're using only the internal AA batteries as the power supply, with nothing connected to the DC IN connector. Use the POWER switch to turn the power on/off.

Mode select switch 6 is the remote control setting. For details on remote control, refer to “Accepting remote control” (p. 28).

Turning the power off

Slide the POWER switch in the direction of the arrow and hold it for two or three seconds until the POWER indicator goes out.

If mode select switch 6 is on, so that remote control is activated, operating the POWER switch will not turn off the power. To turn off the power, disconnect the power cable.

Mode select switch 6 is the remote control setting. For details on remote control, refer to “Accepting remote control” (p. 28).

Caution regarding the power supply

* If you're using an external battery without installing AA batteries internally, the VC-50HD's power will be turned off if you disconnect the power cable from the DC IN connector. Simply reconnecting the power cable to the DC IN connector will not turn the power on again. You will need to use the POWER switch to turn on the power.
* Before making connections to other devices, turn off the power of all devices to prevent malfunction and/or speaker damage.
* Depending on the circumstances of your installation, you may experience an unexpected sensation of roughness when you touch a metallic component of the VC-50HD or of a connected monitoring device or deck. This is due to an infinitesimal electrical charge, which is absolutely harmless. If you are bothered by this, you can connect the grounding terminal shown below to an electrical ground. If this is connected, a slight amount of noise may occur depending on the conditions of use.

If you are not sure how to make this connection, please contact Roland service.

Connections with video devices

This section explains the types of conversions and mode settings provided by the VC-50HD. The correct mode setting must be made in order to perform each type of conversion.

Before switching modes, you must either disconnect your external device from the IEEE 1394 connector, or power-off the VC-50HD.

Converting SDI to IEEE 1394

From a device with an SDI output connector, the SDI signal can be input to the VC-50HD and converted to IEEE 1394. For the audio mode setting, set switches 2 and 3 according to the desired audio output channels.

For details on channel settings for embedded audio, refer to "Specifying the audio input/output channels" (p. 27).

Pay attention to the writing speed if you will be recording on your computer's external media, such as a USB hard disk. Writing errors may occur if you use slower media. Use media that has as fast a writing speed as possible.

Nonlinear editing software that has been verified to work while capturing via the VC-50HD will be listed periodically on the following Roland website.

Connecting Monitors/Mixers

Connecting monitor equipment

The VC-50HD provides an HDMI output connector. You can set up an inexpensive monitoring environment by connecting this to a television or personal computer display equipped with an HDMI input.

* Up/down conversion, I/P conversion, and frame rate conversion are not performed for the HDMI output either.
* The audio channels that are output via HDMI are as follows.
- For HD/SD-SDI input: The channels selected by mode select switches 2/3
•For IEEE 1394 input: Channels 1/2
* Switching the input signal to the VC-50HD while a device remains connected to the HDMI output connector, or frequently connecting or disconnecting a device at the HDMI output connector, may in rare cases result in the picture or audio failing to be output properly, depending on the device connected to the HDMI output connector. If this occurs, reset the power to the VC-50HD or the HDMI device.
* Problems such as faulty contact can also impede correct output of video or audio. Use high-quality HDMI cables.
* The HDMI connector is a precision parts. Handling carefully to prevent contact failure and trouble.

Using the SDI thru-out

If the SDI output of a camera or other device is being input to the VC-50HD and you want the signal to be output to a video mixer or other device in addition to a video recorder, you can use the HD/SD-SDI output/thru-out connector.

By setting the mode select switches located on the VC-50HD's side panel, you can select the audio channels that will be output, and allow remote control from a computer.

Specifying the audio input/output channels

For the SDI embedded audio, only the two specific channels you select will be input and output. Make settings as follows to specify the channels that will be input and output.

* The VC-50HD does not support HDV/DV four-channel audio. If four-channel audio is input, only the two channels 1/2 will be selected.

Selecting which two SDI audio channels go into IEEE 1394

Make the following settings to determine which two channels will go to IEEE 1394.

* If SDI is the source, turn switch 1 to OFF.
