<p>Digital television signal processing apparatus comprise a field store arrangement (1) comprising first, second and third field stores (4,5,6) each capable of storing digital signals relating to one field of a television signal, a digital video tape recorder (2) to supply a digital television signal at a variable rate to the field store arrangement (1), a write control device (7) to supply the digital television signal to at least one of the field stores (4, 5, 6) for writing therein, depending on the rate of supply of the digital television signal, and a read control device (9) to read the stored television signal from at least one of the field stores (4, 5, 6), depending on the rate of supply of the television signal, no field store (4, 5, 6) being written into at the same time that it is read from, and the write control device (7) rotating the writing and reading around the field stores (4, 5, 6) cyclically. Each of the field stores (4, 5, 6) is formed by a plurality, for example four, of field store units (4A etc.) and respective said field store units (4A, etc.) of each of the field stores (4, 5, 6) are grouped together to receive the digital television signal via a common input.</p> |
