Digital television digital format converter having separation registers with calculation unit storing value/finding future signal/applying weightings and applying two signal sets exclusive or function

摘要

The digital converter has a digital input and output. There are an assembly of separation registers. A calculation unit provides an offset signal (4) for the register. A first storage unit (51) contains the conversion value. A second storage unit (52) has a cycle time and finds a future signal (8) the sum of present signals (7). The output is found by applying weightings of the current signal (71) and future signal (81) to an exclusive or function (54).
