USB Broadcast Capture Module (BCM-100)

Overview 

The BCM-100 Broadcast Capture Module captures an external MPEG-2 transport stream and uploads it to a host PC via a USB2.0 interface. Using the supplied driver and suitable third-party applications, the MPEG-2 stream may be decoded, viewed and analysed.
Any compatible low-voltage differential stream may be captured, such as those commonly produced by DVB demodulators.

The BCM-100 also provides a master I²C interface and general-purpose I/O’s for control of external hardware. 

Software Support

The BCM-100 is supplied with a Windows® BDA (Broadcast Driver Architecture) driver, allowing it to be used with a wide range of compliant applications to either view or analyse the captured transport streams. Verified applications include:

• My TV (Windows XP Media Center Edition & Vista Home/Ultimate)
• Cyberlink PowerCinema
• MyTheatre
• DVBStreamExplorer
• TSReader

The BCM-100 BDA driver is derived from LN Systems’ BDA Driver Development Kit.

Peripheral Functions

As well as capturing the MPEG-2 transport stream, the BCM-100 provides two additional interfaces: an I²C master, and general-purpose digital I/O pins.

The master I²C function operates at either 100 or 400kHz (selectable), and supports three access formats: raw, registered (using 8-bit register addressing) and memory access (using 8- or 16-bit memory addressing). Both 7- and 10-bit I²C device addresses are supported.

An RJ-11 connector and flying lead (supplied) allows the BCM-100 to be connected to external devices.

Control of the peripheral functions is via a supplied DLL which simplifies access to the driver. A Windows application is supplied, allowing configuration and control of the BCM-100; example code is also supplied, showing the use of this interface.
