Abstract: Video disc track numbers are conveyed during each video line by means of a quadrature phase shift keyed data carrier recorded along with the picture and sound carriers on a video disc. Upon playback, the data sequence is processed to identify tracking errors occurring within each video field to thereby enable immediate correction of disc tracking errors on a line-by-line basis thus minimizing picture and sound interruption caused by intra-field tracking errors.

A signal processing circuit divides a digitized video signal such that each horizontal scan interval thereof contains a plurality of data blocks, and a signal distributing circuit distributes the blocks of the digitized video data sequentially to the magnetic heads, so that every nth block of each horizontal scan interval is distributed to a respective one of the heads, where n is an even integer. Preferably, there are eight blocks in each horizontal scan interval, and every fourth block is distributed to a respective head.

Abstract: A digital process for controlling the correct reproduction of a composite television signal and in particular of a composite color television signal comprising sequential-type chrominance signals, transmitted or recorded on an information-carrying medium such as a videodisk in which binary-coded pulsed signals are inserted during available intervals of the line scanning return, the binary value of these pulsed signals representing a particular state to be controlled. This value is detected during the process reproducing the composite television signals to make the particular state to be controlled dependent on this value. A first coded pulsed signal may be used for identifying the two components of the chrominance signals. A second coded pulsed signal may be used for identifying the face read of a transparent videodisk having information recorded on both its faces.

Abstract: A system for recording segmented video fields with segment identification codes includes circuitry to encode each segment of a given odd or even field with a different identification code. Further, each corresponding segment of all the other odd or even fields is likewise encoded with the same identification code. Thus, the first segment of any odd or even field has the same identification code which is different from any other identification code appearing for any other segment in any other odd or even field. The same applies to the second and all other segments.

Abstract: A system for playback of segmented video information on a tape employs an ancillary recording medium which is rotationally driven at a rotation rate of the primary segment scanning apparatus. Each segment of a video field is recorded in a respective track of the ancillary medium, the information of one field being recorded over the information of another field. By recording only signals of a predetermined quality on the ancillary recording medium, play back of video information from the ancillary medium will produce a coherent display on a display monitor, regardless of the rate at which the tape is run. This is possible because of the one-to-one correspondence between the rotary rates of the scanner and the ancillary medium. Each coherent display is comprised of information from one or a number of video fields.

Abstract: In the recording of audio-video programs in which the audio is time-compressed and converted into television format, the video frames associated with a given audio frame are recorded in a group immediately following the audio frame, and picture-change cue signals are recorded at selected lines within the audio frame so that on playback, displayed video can be changed at preselected points in the audio frame playback. A number of video frames can be recorded between successive audio frames wihtout introducing any discontinuity in audio playback.

Abstract: Implementations set forth herein relate to an automated assistant that can control a camera according to one or more conditions specified by a user. A condition can be satisfied when, for example, the automated assistant detects a particular environment feature is apparent. In this way, the user can rely on the automated assistant to identify and capture certain moments without necessarily requiring the user to constantly monitor a viewing window of the camera. In some implementations, a condition for the automated assistant to capture media data can be based on application data and/or other contextual data that is associated with the automated assistant. For instance, a relationship between content in a camera viewing window and other content of an application interface can be a condition upon which the automated assistant captures certain media data using a camera.

Abstract: An image pickup apparatus capable of constantly providing a photographer with an appropriate display image even when a posture of the image pickup apparatus is changed is provided. An image pickup device and a main body including a display are connected by a hinge member rotatably about at least one axis. A first detector detects a rotation phase of the image pickup device about the one axis with respect to the main body. A second detector detects a posture of the image pickup device. A display controller performs a vertical inversion of a display of an image picked up by the image pickup device on the display in accordance with a detection result of the first detector and the second detector.
