Video interface for capturing an incoming video signal and reformatting the video signal

Abstract: Video interface for converting a video input signal of one format to a video signal of a second format. Microprocessor control system stores executable script commands, identifying parameters of an incoming video signal and a desired outgoing video signal. An input video template is created, replicating all the pulse events contained in an input video signal. The template is phase locked with the incoming video signal synchronizing an internal pixel clock with the active line period of the incoming video signal. A video output template is created from the executable script for defining an output video signal timing format. The microprocessor-based system provides for complete diversity in capturing an input video signal of one format and converting the same to a different format for display or copying by a peripheral device.

Method and apparatus for recording and reproducing picture information enabling the mixing of images of a video format signal and graphic codes recorded on a single recording medium

Abstract: Method and apparatus of recording and reproducing picture information on a recording medium. In addition to video format signal and a coded information signal, graphic codes including picture information are recorded on the recording medium, by inserting the graphic codes as a subcode of the coded information signal. At the time of reproduction, a signal according to the graphic codes is mixed with the video format signal. When the recording medium is played back, a portion of the video format signal corresponding to a predetermined period of the video format signal read-out from the recording medium is written in a memory, and the signal according to the graphic code is mixed with a still picture video format signal which is produced by repeatedly reading the stored content of the memory.

Apparatus and method for converting video information for printing by a standard printer

Abstract: A system is provided in which video information is converted to a format acceptable for printing by a standard printer, which is also capable of printing non-video based information. The system enables the user to provide a hard copy recording of video information that may be changing rapidly. The system includes an apparatus for converting the video information into a format acceptable for printing by the standard printer. Preferably, the conversion technique does not depend on providing synchronization between the display rate of the video display screen of the video information instrument and the sampling of the video information, nor is it necessary that the number of clock samples associated with the horizontal scan be the same for different instruments from which video information can be obtained. To accomplish such objectives, the video information is sampled at a greater rate than the display rate of the video screen. The obtained video information is stored using digital data. The digital data representing the video information is then reconstructed using a dot boundary algorithm and a dot clock synchronization pattern algorithm, together with translation maps that are used to translate serial bit samples into corresponding representations of display dot intensity levels. The reconstructed video information, which represents the display dots, is outputted by the converting apparatus for printing by the standard printer.

Method and apparatus for recording and reproducing picture information and timely reproducing images by graphic codes

Abstract: Method of recording and reproducing picture information and a recording medium on which the picture information is recorded by the method, and an apparatus for playing such a recording medium. In addition to video format signal and a coded information signal, graphic codes including picture information are recorded on the recording medium correspondingly to playback sections of the video format signal, the graphic codes being inserted as the subcode of the coded information signal. At the time of playback of the recording medium, a video signal according to the graphic codes corresponding to the playback section of the video format signal is generated each time one playback section of the video format signal is played back. Preferably, presence or absence of the graphic codes is displayed each time one playback section of the video format signal is played back.

System for combining multiple audio channels into the baseband video signal and the recovery of the audio channels therefrom

Abstract: A system for enabling a plurality of audio signals respectively representing different languages to be recorded on a present-day video tape in a present day video tape recorder without requiring any additional space on the tape. The bands of audio signals representing the different languages are selectively reproduced so that anyone viewing the video program recorded on the video tape may select any one of a number of languages to accompany the video program. In accordance with the invention, the bands of audio signals representing the different languages are heterodyned to different frequency bands, and are caused to modulate a sub-carrier which, in turn, is inserted into the video signals representing the video content. This enables the audio signals to be recorded in the video tracks of the tape together with the video signals.

Abstract: A video interface circuit for displaying the output of a video camera on a video monitor of the type used for displaying computer output data. In a first mode of operation, data from a video camera is stored in a first video memory while data previously stored in a second video memory is displayed on a video monitor. In a second mode of operation, there is provided the further steps of displaying information previously stored in the first and second video memories alternately on the video monitor. In a third mode of operation, data previously stored in the first and second video memories is read out one word at a time. If a predetermined bit in the word read from the second video memory has a first predetermined logical level, the word read from the first video memory is displayed on the video monitor. Alternately, if the predetermined bit in the word read from the second video memory has a second predetermined level, the word read from the second video memory is displayed on the video monitor.

System for substituting stored video information for another video information

Abstract: A market research system is shown for sub­stituting stored television programs for regularly scheduled, broadcast television programs having a particular identification code wherein the substitute television programs may be transmitted via telephone lines (16, 22) to the households (10) of cooperating panelists for storage. The substitute television programs may be stored and/or transmitted to the panelist's home in compacted or noncompacted form. In compacted form, a memory stores the first frame of video information for the substitute television program and for subse­quent frames, stores only the video information repre­senting a change from the video information stored for a previous frame. In one embodiment, the stored video information represents the difference between each frame and the first frame. In a second embodi­ment, the video change information represents the differences between each frame and the immediately preceding frame. A system for encoding an identifi­cation code in the leading overscan portion of the active line period of a horizontal line of video infor­mation is also shown.

A PC-Compatible, Multiprocessor Workstation For Video, Data, And Voice Communication

Abstract: We present an architecture that combines video, voice, and data capabilities in a PC-compatible workstation. This architecture has been realized as an actual workstation product which provides the user with many communications abilities, including full motion video/audio communication over digital networks. The current version executes a transform based video compression algorithm, using a 16 by 16 pixel discrete cosine transform. During video phone calls, users may transfer computer files, execute programs, send snapshots of computer screens, send FAX messages, and transfer data from other devices through serial data ports built into the workstation. The design also supports storing and retrieving video sequences (with sound) and still pictures on magnetic or optical discs.

Abstract: A video signal processing circuit processes a digital video signal to provide a stereoscopic video signal which can be presented without flicker and without reduced recording time. Digital video fields are consecutively stored in three memories or storage location of a memory, each new field replacing the oldest one. The fields are stored at a first clock rate. The stored video is read out at twice the first rate with each successive pair of fields being read out twice.

Video disk playback apparatus

Abstract: A video disk playback apparatus for playing back video image information recorded on a disk, such as a laser disk. The information recorded in the disk is read out as playback signals, which are separated into an analog composite video signal, digital data and digital audio data. The analog composite video signal is either directly reproduced as a moving picture, or is converted into digital composite video data and stored in a video data memory. On the other hand, the digital data is converted into digital video data having the same format as the digital composite video data and is stored in the same video data memory as the digital composite video data. The digital data being read out from the disk, such as track number and frame number, are converted into a format that can be recorded into the video data memory, and hence the video data memory for storing the digital composite video data can be shared, so that a memory circuit for the digital video data is not needed. It is also possible to cope with the case of recording a large capacity of digital data such as graphic data and still pictures onto a video disk.

Chunky planar data packing apparatus and method for a video memory

Abstract: An apparatus and method for taking data that is presented on a NUBUS in NUBUS format and writing it into a video memory in chunky planar format, is described. The present invention is also useful for performing RGB reads wherein video data is read from the video memory in chunky planar format and is translated into NUBUS format for transmission across the NUBUS. The apparatus comprises a data format translator which is coupled to the NUBUS for translating the RGB data from NUBUS format to chunky planar format. The translated RGB data in chunky planar format is compressed and rearranged as compared to the NUBUS format--resulting in a more efficient utilization of video memory space. An address generator is also coupled to the video memory for calculating the address location in the video memory where the translated RGB data is to be written. The address location is derived from the NUBUS address according to the formula N start =(3*NAD/4) where N start is the start address in video memory and NAD represents the NUBUS address from which the RGB data to be translated is obtained.

HD-PRO™: A New Global High-Definition Video Production Format

Abstract: This article introduces a production format that complements all known transmission formats. In addition, the proposed new production format, called HD-PRO, offers extremely high spatial resolution, making it suitable for archival masters and post-production image manipulation. HD-PRO is best regarded as an extension of the recently announced SMPTE 240M standard (often referred to as the 1125/60 format). A great deal of creative work has gone into the establishment of 240M, and HD-PRO should be viewed as a complement to that format, with each format designed to suit a different subset of applications.
