When you open the Hollywood DV-Bridge box, you’ll find a base, a six-foot-long, six-pin FireWire cable, an AC adapter, a thin manual, the DV-Bridge itself and a CD containing drivers, the latest read-me file and editing software. Since it has passthrough FireWire and analog connectors, you can keep it ready to hook up to your source deck or camcorder at any time. Regarding permanent installations, have you noticed how most FireWire ports are on the backs of computers nowadays? The Hollywood DV-Bridge can act as a much more convenient connection station, or a generic breakout box. When you connect your digital camcorder to your computer for capturing footage, the Hollywood DV-Bridge allows you to use an NTSC television monitor instead of the little LCD screen on the camcorder as a monitor.Įven if you own a DV camcorder that has analog inputs, you may still want to obtain the Hollywood DV-Bridge so you have can a permanent installation. In addition to the conversion duty, which is its primary function, the Hollywood DV-Bridge has some other helpful uses. Use the mode-selector button to choose the appropriate function. Simply hook up your analog source to the front (input) side, and your digital destination deck to the back (output) side, of the Hollywood DV-Bridge. It can perform video conversions both ways without connecting to a computer at all, which is a very useful function if you own a DV camera that does not have analog in. When connected to a computer, the Hollywood DV-Bridge will auto-detect the appropriate mode based on the connections you have made. The Hollywood DV-Bridge also performs a digital-to-analog function, so you can get your edited productions out of your computer’s FireWire port and onto a tape that will play in your VCR. This allows you to capture footage from an analog source to your computer through your FireWire card. Welcome to Hollywoodįirst and foremost, the Hollywood DV-Bridge is a video digitizer with LANC control of your analog source. The Hollywood DV-Bridge is a stand-alone analog-to-digital or digital-to-analog converter with the added ability to control your source deck or camcorder equipped with LANC so you can perform batch captures of your analog footage. If you have a FireWire-equipped computer, but don’t own a DV camcorder, or if you have an older DV camcorder that does not include analog inputs, you may need a digital-to-analog converter. The rate of new values is called the "sampling rate" or " sampling frequency" of the converter.Folks who would benefit from a device for converting video from analog to digital are just the sort of people Dazzle had in mind for its Hollywood DV-Bridge. It is therefore required to define the rate at which new digital values are sampled from the analog signal. The analog signal is continuous in time and it is necessary to convert this to a flow of digital values. One should consider taking this phenomenon into account before choosing an ADC. This table shows, for example, that it is not worth using a precise 24-bit ADC for sound recording if we don't have an "ultra low jitter" clock.

:E FSR is the full scale voltage range = V_, where q is a number of ADC bits. Where::Q is resolution in volts per step (volts per output code), The voltage resolution of an ADC is equal to its overall voltage measurement range divided by the number of discrete intervals as in the formula: Resolution can also be defined electrically, and expressed in volts.
signed integer), depending on the application. unsigned integer) or from -128 to 127 (i.e.
The values can represent the ranges from 0 to 255 (i.e. For example, an ADC with a resolution of 8 bits can encode an analog input to one in 256 different levels, since 2^8 = 256. In consequence, the number of discrete values available, or "levels", is usually a power of two. The values are usually stored electronically in binary form, so the resolution is usually expressed in bits. The resolution of the converter indicates the number of discrete values it can produce over the range of analog values. However, some non-electronic or only partially electronic devices, such as rotary encoders, can also be considered ADCs.
#How an analog to digital video converter code#
The digital output may be using different coding schemes, such as binary, Gray code or two's complement binary. Typically, an ADC is an electronic device that converts an input analog voltage (or current) to a digital number. The reverse operation is performed by a digital-to-analog converter ( DAC). An analog-to-digital converter (abbreviated ADC, A/D or A to D) is an electronic integrated circuit, which converts continuous signals to discrete digital numbers.
