A method and apparatus are described for the electronic delivery of a document, originated at a local site by a source which has a printer output that normally is connected to a printer, to one or more remote locations having printers or display devices which may differ from the printer normally connected to the printer output of the document generating source. Printer command signals which normally are provided at the printer output are converted to character and position data which represent t...

A method and apparatus for the electronic delivery of a document, originated at a local site by a source which has a printer output that normally is connected to a printer, to one or more remote locations having printers or display devices which may differ from the printer normally connected to the printer output of the document generating source. Printer command signals which normally are provided at the printer output are converted to character and position data which represent the respective ...

A method of and apparatus for determining and displaying the postal rate for a parcel to be shipped to a destination zone by a selected class of shipment in accordance with the weight of the parcel. A memory is provided with plural sections, each section being substantially associated with a particular class of shipment, and each section storing postal rate data for predetermined weight increments at addressable locations. The address of a location is determined by the parcel weight and the dest...

Intermediate vertical synchronizing signals are generated to occur between the vertical synchronizing signals normally included in a conventional video signal. A first counter counts clock signals which are synchronized with the horizontal synchronizing signals normally included in the conventional video signal to provide a count representing the number of clock signals which are present in one-half of a field interval of that conventional video signal. The count provided by the first counter du...

In a camera having a lens for focussing incident light onto a light reception surface of a pick-up so that the latter outputs a camera signal, a stop for limiting the amount of the incident light, and a variable gain amplifier for correcting the level of the camera signal; there is provided a control circuit which controls a focus of the lens, the stop and a gain of the variable gain amplifier on the basis of the output of the variable gain amplifier, thereby simplifying the construction of the ...

Apparatus for superimposing graphic title image signals onto an input video signal to produce a video picture having graphics, such as title images, superimposed thereon. Graphic title image data is written into a memory and subsequently is read out under the control of an address generator whose read-out addresses are shifted at a given repetition rate to change the positioning of the graphic title image data relative to the video signal, thereby producing a scrolling effect of the graphics acr...

In, for example, a motion compensated video standards converter wherein blocks in a first field or frame of a video signal are each compared with a plurality of blocks in the following field or frame of the video signal for deriving a plurality of motion vectors representing the motion of the content of respective blocks between the first field or frame and the following field or frame, a respective motion vector is derived, from the plurality of motion vectors for each pixel in each block of ea...

In, for example, a motion compensated video standards converter wherein blocks in a first field or frame of a video signal are each compared with a plurality of blocks in the next succeeding field or frame of the video signal for deriving motion vectors representing the motion of the content of respective blocks between the first field or frame and the next field or frame, the blocks in a border region of each field or frame are assigned the same motion vectors as have been derived for the respe...

In an apparatus for magnetically recording and/or reproducing digital signals in a plurality of modes characterized by different respective formats, pilot signals having different frequencies are generated to identify the modes, respectively, and, during a recording operation in one of such modes, the respective pilot signal is mixed with the digital signal to be recorded for providing a resultant mixed signal which is recorded. Thereafter, during a reproducing operation of the apparatus, the pi...

In, for example, a motion compensated video standards converter blocks in a first field or frame of a video signal are each compared with a plurality of blocks in the following field or frame of the video signal for deriving motion vectors representing the motion of the content of respective blocks between the first field or frame and the following field or frame, a correlation surface is generated for respective blocks in the first field or frame, the correlation surface representing the differ...
