48 / 112 page ![]() Functional Description STV2310 48/112 ● VPUD31: This byte provides the MSB contents of VPS byte 13. ASM[5:0]Announced start minute. NC[3:0]Nationality code which is used to identify the source of the item. ● VPUD40: This byte provides the LSB contents of VPS byte 14. ● VPUD41: This byte provides the MSB contents of VPS byte 14. NC[3:0]Nationality code which is used to identify the source of the item. PSC[5:0]Program source code used to identify the source of the item inside the country identified in the nationality code. ● VPUDS0: This byte provides the result of data coding checks. ● VPUDS1: This byte provides the result of data coding checks. VPSVDA:Valid VPS Data. This bit is set when the VPS Start code has been matched and a full VPS data flow has been sliced. When this bit is reset, it indicates that at least part of the VPS data flow has not been received (in case of a too short TV line, for example). VPSER1:Bi-phase error in the 1st VPS Byte. Data is written but there was a bi-phase error. VPSER2:Bi-phase error in the 2nd VPS Byte. Data is written but there was a bi-phase error. VPSER3:Bi-phase error in the 3rd VPS Byte. Data is written but there was a bi-phase error. VPSER4:Bi-phase error in the 4th VPS Byte. Data is written but there was a bi-phase error. VPSER5:Bi-phase error in the 5th VPS Byte. Data is written but there was a bi-phase error. UDW Coding for WSS In Wide Screen Signaling (WSS), a nibble split algorithm is applied. In all bytes, bit 6 is the even parity check of bits 5 to 0. Bit 7 is the complement of bit 6. ● WSUD00: This byte provides the LSB contents of the WSS 1st group of data. bit 7 65 432 10 0 0 ASM5 ASM4 ASM3 ASM2 bit 765 43 210 0 0 PSC3 PSC2 PSC1 PSC0 bit 765 43 210 0 0 NC1 NC0 PSC5 PSC4 bit 765 43 210 0 0 VPSER4 VPSER3 VPSER2 VPSER1 bit 765 43 210 0 0 0 0 VPSVDA VPSER5 Table 20: UDW Coding for WSS ADF DID SDID DC WSUD 00 WSUD 01 WSUD 10 WSUD 11 WSUD 20 WSUD 21 WSUD 30 WSUD 31 CS bit 765 43 210 0 0 WSS3 WSS2 WSS1 WSS0 |
