发明名称 INTER-FIELD MULTIPLEX MULTI-POINT PICTURE COMMUNICATION SYSTEM
摘要 PURPOSE:To attain inter-field multi-point picture communication without flicker on screen by applying field multiplex picture communication to an even point number. CONSTITUTION:A picture from a transmission line 1 via a separator 2 is sent through a transmission line 3 to a terminal equipment 6(B), where three fields B1 are consecutively displayed and then three-fields B4 are displayed consecutively while skipping fields B2, B3. Then a field B7 is displayed while skipping fields B5, B6, a field B10 succeeds a field B7, and the displayed fields have a regularity of B1, B4, B7, B10, B13...B3n-2. That is, even number fields and odd number fields are displayed alternately in the terminal equipment 6(B), one frame is constituted in the still picture part and this is applied similarly to terminal equipments 7(C), 8(D). Thus, the inter-field multi-point communication is implemented without flickered screen.
