ABSTRACT:
Apparatus is described for multiplexing data recorded in a spatially and temporally demultiplexed manner on tape 12 and replayed by a plurality of replay heads A, B, C, D organized in groups, where each group includes a plurality of replay heads A/C, B/C, connected in common to a head channel 42, 44. First multiplexers 84, 92 multiplex the data in respective head channel, the output of the first multiplexers being stored in respective video buffers 86, 94. A second multiplexer 88 then selectively addresses the video buffers in response control signals to produce a multiplexed output which can reliably be reproduced even under extreme error conditions and in all playback modes.
