摘要:
The invention relates to a storage medium on which a set of data is stored, whereby a first data section of the data set is stored in a read-only memory area and a second data section of the data set is stored in a read/write memory area, and the data set comprises language-independent data and language-dependent data. The data set can be processed in a handling device either in a first processing form related to a first language, or in a different processing form related to a second language. Language-independent data and language-dependent data which are related to the first language are included in the first data section, and language-dependent data which are related to the second language are included in the second data section. For the processing in different form, data from the second data section as well as data from the first data section are to be used.

Electrical contact surfaces, especially when connected to a chip, are designed to be purely functional. However, according to the present disclosure, the contact surfaces are designed so that their external shape is that of a visible letter or symbol with a meaningful content. These contact surfaces may, e.g., be placed on cassette casings for recognition. In a stripe or bar code unit consisting of several code components, i.e., bars, individual bars are electrically conductive to facilitate additional coding. The electrically conductive bars or the contact surfaces are preferably connected to the terminals of an integrated circuit.

A cassette for use with a recording apparatus comprises: a housing for a recording medium, the housing having a first surface and side walls, the recording medium being accessible through one of the side walls; at least a part of a chip card affixed to the housing, forming a second surface of the housing and closing the cassette, the chip card part having a memory formed integrally therewith and externally accessible contacts; and, the contacts of the chip card being positioned on the second surface to be engageable by corresponding contacts in the recording apparatus when the cassette is inserted therein. One of the side walls has an access door for the recording medium and the second surface forms an upper wall of the housing as defined by the access door. The part of the chip card forming the second surface of the housing has a marking position at which light transmissivity can be controlled. The marking position can be rendered non transmissive to light to prevent recording.

In the process of generating a compatible 4:3 letterbox format television signal, a wide aspect ration 16:9 progressive scan television signal is vertically transcoded from 575 to 431 image lines, converted to line interlaced form and horizontally compressed. A vertically transcoded interlaced luminance component is converted back to progressive scan form via interpolation, and subtracted from a vertically transcoded original progressive scan luminance component to produce a difference (helper) signal. The difference signal is time compressed and multiplexed into upper and lower edge bar regions of the letterbox format. The compatible letterbox signal also is encoded with additional information including vertical high frequency information and horizontal high frequency information separated during the transcoding and compression processes, respectively. The encoding includes modulating the color subcarrier frequency with luminance information, and intraframe averaging. The difference signal and encoded additional information are used by a 16:9 widescreen receiver to produce a 16:9 progressive scan image display with the transcoded number of lines and good resolution.
摘要:
There is disclosed a communications terminal, including a video telephone, for transmitting and receiving video and audio. The terminal includes video recording apparatus and video reproduction apparatus with the video recording apparatus being switchable into an "off" mode by operation of a flap. In order to use the transmission capacity of the communications terminal even when the flap is closed, an image which already exists in a video memory is transmitted. A changeover is automatically made to the video memory by operation of the flap.

A television camera includes an acceleration correction device for correcting for sudden movements of the camera, to prevent blurring of the resulting television picture. The correction device changes the starting point on an image target depending upon the amount and direction of the acceleration. This correction does not occur until the acceleration exceeds a threshold value.

A video recording and playback device has a control track recorder for recording a control track signal including timing edges recorded on a tape or other storage medium together with the video program. A decoder is coupled to the control track signal and to the tape drive for switching among a forward play mode, a forward skip mode and a rewind mode, as a function of play, skip and rewind codes inserted into the control track as phase variations of edges other than those used for timing, or preferably as pulses with sloping edges distinct from the timing edges. In addition to selectively skipping sections of the video program preceded by a skip code and followed by a play code, such as commercial breaks, the device permits user editing of play and skip codes and selective multiple replays of sections of the video program preceded by a play code and followed by a rewind code. Replay can be continuous or for a predetermined number of replays, encoded in the control track signal with the play, skip or rewind codes. The play, skip and rewind codes and/or the number of play repetitions are user editable from an on screen menu for changing the content to be presented during a later playback.
摘要:
A method and to an apparatus for electronically processing video signals stored on a record carrier, particularly a magnetic tape or magnetic or optical disk. The video signals are scanned from the record carrier in sections, are written into an intermediate memory, are processed, for example corrected, using a processor and are recorded from the intermediate memory in processed form on a second record carrier or on the same record carrier.
摘要:
A pulse code modulated audio signal transmission system which compensates for signal interference in the pulse code modulated audio signal. The system includes a first device for receiving an audio signal and for converting the audio signal into a pulse code modulated audio signal, and a second device for receiving the audio signal and for producing an auxiliary signal corresponding to the audio signal but having a smaller bandwidth than the audio signal. A transmission circuit is connected to the first and second devices for receiving the pulse code modulated audio signal and the auxiliary signal and for producing an output signal which comprises the audio signal with portions of the audio signal which contain interference being substituted with corresponding portions of the auxiliary signal.

In the voice control of a device appertaining to consumer electronics, speech inputs of a user are converted into digitized voice signals. First features, which are characteristic of the individual sounds of the speech, and thus permit recognition of the spoken sounds, are extracted from the digitized voice signals. Furthermore, second features, which permit a characterization of the voice of the respective user and are used for distinguishing between the speech inputs of different users, are extracted from the digitized voice signals. This enables the device being operated to distinguish between speech inputs of the present user, which represent operator-control commands, and utterances by other persons, and to respond only to operator-control commands of the present user. Furthermore, the quality of an analysis of the viewing habits of different users can be improved by a distinction between the users.
