The invention relates to an electronic device with an optical unit for reading information stored on an information plate and for writing information on an information plate, characterized in that the electronic device comprises a transport mechanism for the transport of at least two information plates between a storage position and a playing position provided both for reading and for writing, in that a memory unit is provided for the intermediate storage of information, and in that an alternate transport of the first and of the second information plate between the playing position and the respective storage position is provided for the purpose of copying information from a first information plate to a second information plate, such that alternatively in a first time interval a read-out of information from the first information plate and an intermediate storage of this read-out information in the memory unit are carried out, and in a second time interval the information stored in said memory unit is written onto the second information plate.

Electronic device

Television system in which digitalized picture signals subjected to a transform coding are transmitted from an encoding station to a decoding station. In a television system a digital picture signal is subjected to a transform coding for the purpose of bit rate reduction. In order to detect motion effects between the two fields of a picture, these fields are also examined in a motion detector 8310. If no motion is detected, intraframe transform is employed and if motion is detected intrafield transform is employed. Small motion effects can be eliminated by subjecting the picture signal to a median filtering before subjecting it to an intraframe transform.
