Embodiment Construction

[0033] The invention provides an inverter adapter and a system using the inverter adapter. The inverting adapter of the present invention inverts the inverted DVB-ASI to generate an adapted DVB-ASI signal. This adapted DVB-ASI signal can now be used by any DVB-ASI device. The inverter adapter can be contained in a small box and is easily connected to any amplifying device that generates inverted DVB-ASI signals. In addition, the inverting adapter of the present invention can be integrated with the amplifying device to automatically provide the adapted DVB-ASI signal.

[0034] The inverter adapter may include a transformer for receiving a DVB-ASI signal and outputting an inverted DVB-ASI signal. The adapted DVB-ASI signal will preferably be the inverted version of the inverted DVB-ASI signal. As used herein, "inverted" means that each bit of the inverted DVB-ASI signal will be converted to the opposite binary value. For example, a series of inverted DVB-ASI bits of "01110" will be ...

Abstract

An inverting adapter is disclosed that inverts inverted DVB-ASI signals to produce an adapted DVB-ASI signal. This adapted DVB-ASI signal may be used by any DVB-ASI device. The inverting adapter can be contained in one small package and easily connected to any of the various amplification devices that produce inverted DVB-ASI signals. Alternatively, the inverting adapter of the present invention may be integrally formed with an amplification device to automatically provide the adapted DVB-ASI signal.

Description

Technical field [0001] The present invention relates to digital video, and more particularly to an asynchronous serial interface (ASI) inverter adapter and system of video broadcasting (DVB). Background technique [0002] Digital video has become increasingly important. Generally, several formats can be used when generating and processing digital video signals. One such format is called the Serial Digital Video (SDV) format, which is a way of continuously packing raw digital data from moving images. For example, a digital video camera can use the SDV data format to generate scene images of a movie. There are several SDV-related standards, such as the 259M and 125M standards of the Society of Motion Picture and Television Engineers (SMPTE). These standards determine, for example, what is compressed in the data stream, the speed of the data stream, and the encoding of the data. [0003] Another popular format used when transmitting digital video is Digital Video Broadcasting-Asynch...
