... TRS signal errors. The device also detects and indicates the input video signal standard. The GS1500 can detect and re-map illegal code words contained within the active portion of the video signal. The positions of the embedded ANC data are indicated and the ANC data may be extracted and accessed by the user through an internal FIFO interface ...

... Input Control Signal Input. Used to control where the FIFO_L signal is synchronous generated. When F_E/S is high, the GS1500 generates FIFO_L signal at EAV. When F_E/S is low, the GS1500 generates FIFO_L signal at SAV. See Fig. 4 for timing information. Synchronous Input Control Signal Input. Used to enable or disable blanking of the wrt PCLK_IN LUMA (DATA_OUT[19:10]) and CHROMA (DATA_OUT[9:0]) ...

... RESET ANC_DATA_Y GENNUM CORPORATION TIMING TYPE Non- Input Control Signal Input. Used to enable or disable re-insertion of the synchronous TRS into the data stream. When TRS_INS is high, the device re- inserts TRS into the incoming data stream based on the internal calculation. The original TRS packets are set to the blanking levels ...

... Synchronous Output Control Signal Output. VD_STD[3:0] indicates which input video wrt PCLK_IN standard the device has detected. The GS1500 will indicate all of the formats in SMPTE292M (see Table 3) plus it will indicate an unknown interlace or progressive scan format. Synchronous Output Status Signal Output ...

... In external FIFO control mode, the internal FIFO address pointers are reset to zero (0) using FFRST. A recommended external reset process is shown in Figure 16. 3.7 READING CRC ERROR FLAGS The GS1500 provides error flags which track the Cyclic Redundancy Code embedded in each line of LUMA and CHROMA video streams LINE_CRC_ERR_C, respectively) ...
