Abstract:
An apparatus for receiving a digital video conference signal including data frames transmitted along a plurality of transmission lines, said data frames having frame synchronization information, the apparatus comprising:data receiving means for receiving said data frames from said plurality of transmission lines;data parsing means for parsing said received data frames into units of a predetermined number of bits;synchronization signal detecting means for examining each of said units and for detecting a particular unit with a predetermined bit pattern indicating said frame synchronization information, said particular unit designating start of a first data frame;a counter for receiving said units and counting a number of units following detection of said particular unit by said synchronization signal detecting means up to a predetermined number of units, said predetermined number of units corresponding to a size of said first data frame;a buffer memory for sequentially storing said units parsed by said parsing means; andoutput control means connected to an output of said counter and for controlling said buffer memory to output the stored units until said counter reaches said predetermined number of units, whereby said first data frame is received and compensated in phase.
