Abstract
A read device (320) for reading a record carrier (184) on which coded pictures (4TV, TV, TV/4) have been recorded. The recorded coded pictures represent pictures made up of a matrix of P rows of Q pixels (p). The dimension of the pixels in a horizontal direction is substantially equal to the dimension of the pixels in a vertical direction. A read unit (6) reads the recorded coded pictures (4TV, TV, TV/4) from the record carrier (184). The device comprises a picture converter, which preferably comprises a sample rate converter (290), for converting the read-out coded pictures into an adapted coded picture comprising P'.times.Q' coded pixels. The sample rate converter is arranged in a data path between the read unit (6) and a picture memory unit (321). The picture memory unit (321) supplies a coded picture representing a picture made up of pixels (p') whose ratio between the dimension in the horizontal direction and the dimension in the vertical direction is substantially equal to Q/P, P and Q being integers. The coded pictures supplied by the picture memory unit (321) are converted into a video signal suitable for a standard TV set.
