摘要

Describes a provision,A receiver and Methods of ATV (Advanced Television) that encodes Data flows in a basic variable length symbol of multiple level Signal which comprises a Plurality of packetsFixed length Data Multiplexed without synchronization information.The Fixed length Data are placed in fields or Repetitive Data Segments.Each of which includes a pull Signal Data segment and each field of which includes a field synchronization Signal.The Fields of Data segments sontransmitidos as VSB suppressed Carrier Modulation.ATV at a receiver, the synchronization of Data segments is used togenerate a desynchronization signal that identifies the beginning of each fixed length data package.In One embodiment, a synchronization signal is inserted in each Data Packet Package fixed length recovered to recover the data streams.In another Mode, The recovery of the Elementary data streams is performed without Inserting a packet Signal synchronization.
