Arrangements for recording and reproducing datareduced videoinformation are described. The recording arrangement comprises a datareduction unit (3) and a formatting unit (4). The formatting unit (4) generates packets (Pi) each having a first, second and third packet portion (PP1, PP2 and PP3). The first packet portion comprises a sync word (SW) and an identification word. The second packet portion comprises datareduced videoinformation of a first and a second datablock (MB0, MB1). A datablock comprises DC coefficients (DCi) and most significant and least significant AC coefficients (MACi, LACi).; The videoinformation comprised in the first and the second datablock are stored in the second packet portion (PP2), such that the DC coefficients of the first datablock (DC0) are stored first, the plurality of most significant AC coefficients (MAC0) of the first datablock are stored next, the DC coefficients of the second datablock (DC1) are stored last in the second packet portion, and the plurality of most significant AC coefficients (MAC1) of the second datablock are stored before the DC coefficients of the second datablock in the second packet portion. This enables an improved reproduction of the videosignal in a feature mode.
