... GS9000 decoder, the GS9001 provides EDH insertion and extraction for 4ƒsc NTSC, 4ƒsc PAL and 4:2:2 component standards MHz luminance sampling. The GS9001 also generates timing signals such as horizontal sync, vertical blanking, field ID and ancillary data identification. The ancillary data identification aids the extraction of ancillary data from the data stream ...

... Calculated CRC words can be read through the interface. CRC Comparison The GS9001 can be configured for transmit or receive mode. In receive mode, the calculated CRC is checked against the incoming CRC embedded in the error data packet. Any mismatch will generate status error flags to indicate transmission 2 related error flags in either active picture, full field or both ...

... EDH Passthrough Mode An EDH passthrough mode is available to aid in system diagnostics. This mode is selected by address 1,0 on A1, A0 pins. In this mode, the GS9001 will not insert a new EDH packet into the data stream. Input data is bypassed to output without modification. Error flag status available through the ...

... DA will recode the incoming EDH flag as EDA (Error Detected Already) and pass the IDA flag. An additional transmission error occurs between the DA and the production switcher which is flagged as EDH . The GS9001 in the production switcher now has a list of error flags that can be reported locally or through a communications interface to a central maintenance station ...
