  • Patent number: 4109276
    Abstract: In a television signal synchronizer having a coherent memory, it is necessary to modify the writing of data into memory or the reading of data out of memory in order to provide field conversion. In the described apparatus, the reading out of data is always done according to a non-variant sequence determined by the local (studio) reference timing signals. In a first embodiment the read address generator signals are modified so as to read out the stored video signal in accordance with the non-variant write in sequence. In a second embodiment the write address generator signals are modified so as to position the incoming video signal into memory so that it is located in the proper memory position for the non-variant read out sequence.

  • Patent number: 4101926
    Abstract: Television synchronizer apparatus includes a coherent memory with preassigned fixed burst phasing of 0.degree. or 180.degree. for each line store of color video image information. The incoming synchronizing components including burst are discarded on the premise that they are well-known repetitive functions. The incoming color video image information is read into the memory coherent with the preassigned burst phasing, thereby significantly reducing the memory storage capacity normally utilized to store sync and burst information.
