Image Buffer, Bus Synchronization | Motorola IEEE 1394.B specs

Bus Synchronization

The new XCD Series also features a bus synchronization function enabling users to simultaneously capture images from different angles with multiple cameras by sending a single trigger to all cameras from the host PC. This feature is not only useful for viewing images from different angles, but can be used to recreate a 3D image for more detailed inspection.

Image Buffer

The new XCD Series is equipped with an image buffer, which serves as temporary storage for captured images for later transmission or retransmission. This function allows users to maximize bandwidth in multiple-camera operations or reconfirm specific images as required.

Broadcast Delivery

The broadcast delivery function of the XCD Series can be used to send a software trigger to multiple cameras in a daisy chain. This not only facilitates connections, but eliminates the need for using a hardware trigger which can produce false triggers due to noise. In addition, the broadcast delivery function can be used to simultaneously change camera settings such as shutter speed, exposure, white balance, gain, and more.

Bulk Trigger Mode

The new XCD Series has a bulk trigger mode to allow the capture of up to 16 images in rapid succession using either a software or hardware trigger. This can be used to capture multiple images of an item at different shutter speeds. By doing so, specific areas of that item can be clearly seen without changing the lighting. Also this allows a composite image with a wide dynamic range to be reproduced.

Vertical and Horizontal Partial Scanning

By selecting a particular area of an image to be scanned, users of the XCD Series can reduce data size and increase frame rate to minimize processing time.

Vertical and Horizontal Binning*2

The Vertical binning feature of the XCD series combines image data for every two lines vertically resulting in increased frame rates and reduced processing time. Horizontal binning combines image data for every two pixels horizontally to achieve greater sensitivity, faster capture speeds, and quicker processing.

New Sony 1394.b Driver and SDK

A new low level 1394.b driver for these cameras achieves reliable and efficient image transfer without relying on Microsoft’s standard Windows® driver. In addition, the new cameras are backward compatible with the current fcam 1394a driver.

IEEE 1394.B specifications

Motorola's contribution to the IEEE 1394.b standard revolutionized the way devices communicated with each other, facilitating high-speed data transfer in various applications. The IEEE 1394.b, commonly known as FireWire or i.Link, is an advanced version of the original IEEE 1394 standard, which aimed to provide a seamless and efficient communication interface for multimedia devices.

One of the standout features of IEEE 1394.b is its data transfer rate. While the original specification supported speeds up to 400 Mbps, IEEE 1394.b increased this capability significantly to 800 Mbps and beyond. This high-speed transmission allows for the connection of multiple devices, such as digital cameras, hard drives, and printers, creating a flexible and expandable network.

The technology supports a peer-to-peer communication model, allowing devices to communicate directly without the need for a central controller. This architecture promotes efficient data exchange, making it ideal for environments with multiple connected devices. Moreover, the standard includes dynamic bandwidth allocation. This means that the available bandwidth can be intelligently distributed among connected devices based on their current needs, optimizing performance across the network.

Another noteworthy characteristic of IEEE 1394.b is its hot-swappable nature. Users can connect and disconnect devices while the system is powered on without experiencing any interruptions or device failures. This feature enhances usability, especially in settings where devices frequently need to be added or removed.

In terms of physical characteristics, IEEE 1394.b uses a variety of connector types, including the 6-pin and 9-pin connectors, for different applications. The cabling can also extend longer distances than previous standards, with devices able to be connected up to 100 meters apart using optical fiber cables, facilitating greater flexibility in device placement.

Furthermore, the IEEE 1394.b standard improves power management capabilities. Devices can draw power through the FireWire connection, simplifying setups by reducing the number of necessary power supplies. This power delivery not only streamlines connections but also contributes to a decreased need for bulky power adapters.

In summary, Motorola's role in developing the IEEE 1394.b standard has had a lasting impact on data communication technology. Its high-speed transfer capabilities, peer-to-peer architecture, hot-swappability, flexible cabling options, and efficient power management make IEEE 1394.b a versatile choice for a wide range of multimedia applications. The standard continues to serve as a vital part of device connectivity, especially in professional and consumer electronics.
