Abstract

High definition television signals are sent. Will be represented by the current Manure that was put into a set It is characterized as a sequence of data fields (Fig. 1) with inconsistent data rates due to unequal information intervals between the headers. In which each field Will be preceded by the header portion that is the sync field followed by A series of 312 data segments where each section contains the relevant information header (FEC) on the transmitter (Fig. 33). The transmitting processor (14) produces a data set that contains The header is in it. And it will provide uninterrupted operation at a constant data rate while supplying such a series of streams to the circuit network (17), which creates a series of data fields by Inserting missing header information into the stream. Send processor Will work better With constant data rates Without having to modify the original data field structure So as to According to the constraints of the circuit, it is created by creating a data field. This effect can be conveniently achieved by transmitting data from the process chaser to the linker / buffer circuit (46) in response to the signal. The symbol clock 3/8 in conjunction with the specified buffer level. Especially said The recording / playback device (15) receives a series of streams at a constant data rate from The processor sends and outputs. Where the data stream with a constant data rate is constant To the linker / buffer circuit, the transmitter / decoder pro chaser (86) on the receiver (Fig. 34) will work with the Data field processors (75) and will show uninterrupted operation with data rate at Constant The recording / playback device (85) receives a steady, constant stream from its Link / buffer (84) after the header information is extracted. And will give an output that is A stream with a constant data rate to the transmitted decoder.
