摘要： In a television circuit arrangement for field and line frequency doubling and picture part magnification (zooming), in order to obtain the frequency doubling, information is written, alternately, into two field memories (M1, M2) during a field period having line periods at a given writing speed (clock frequency fc), whereby the reading from the field memories takes place at twice the writing speed. For a picture part magnification to be carried out in a simple manner, a magnification control circuit (TG, S3, S4, S11, S12) having a clock signal change-over circuit (S3, S4) is provided, as a result of which during writing, a higher writing speed (clock frequency 2fc) than the said given writing speed (clock frequency fc) is used during a part of the field periods and of the line periods, which part is substantially inversely proportional to the ratio between the higher writing speed and the given writing speed. For intermittent writing, one or more change-over circuits (S11, S12) are provided at the memory signal inputs, which provides, besides a more effective information storage and an improvement of the picture quality, the possibility of movement detection and recursive signal processing for noise reduction.

摘要： A movement-adaptive processing circuit for an interlaced video signal has a selection circuit (5) which passes on to its output (21) one of the three video signals applied to its inputs (3, 9, 11) and which signals substantially correspond to three position-sequential lines of two consecutive fields when this signal has an amplitude which is closest to the mean amplitude of these three video signals. The processing circuit may be used many types of circuits such as, for example, in line or field number conversion circuits, noise suppression circuits, DPCM decoding circuits, vertical contour correction circuits and still-picture display circuits of video record players.

摘要： In a series-parallel-series memory circuit (3) which requires a write clock signal (at 19), a transfer clock signal (at 25) and a read clock signal (at 31), it is sufficient, because a clock signal processing circuit (23) is provided, to apply only two clock signals (to 33 and 35). Using a gate circuit (41), it is possible to obtain from one clock signal (applied to 35) additional information, which is provided by means of pulse duration variation, for adapting the time delay of the memory circuit (FIG. 1).

摘要： In a field number conversion circuit, the mutual positions of the horizontal and vertical synchronizing signal pattern in a field of the television signal to be converted are measured by means of a measuring circuit (201) and these mutual positions are adequately transferred by means of a coupling circuit (203) to a corresponding field in the converted television signal.

摘要： Method of transmitting signals between communication stations via a network, in which a central control station is adapted to transmit a picture of a virtually real ambience to each connected station. In the picture, connected stations are represented by objects which can be displaced by the user of the corresponding station. Other stations such as information sources are represented by stationary objects in the form of buildings. As soon as objects touch or overlap each other, an actual communication connection (for example a telephone conversation, a database consult, a transaction) is established between the corresponding stations. A "chat box" application is also provided, with the particular property that the extent of interaction between conversation partners is dependent on the mutual distance between their corresponding objects in the picture.
