The European Broadcasting Union (EBU) maintains several tables of Country and Network Identification (CNI) codes. CNIs of type VPS, 8/30-1 and 8/30-2 can be used to identify networks during a channel scan.

This field contains the CNI of the network found in a VPS packet. It can be zero if unknown or CNI's are not applicable. Note VPS has room for only 4 lsb of the country code (0xCNN).

For example ZDF: 0xDC2.

Examples:
examples/network.c.

CNI of the network from Teletext packet 8/30 format 1, zero if unknown or not applicable. The country code is stored in the MSB, the network code in the LSB (0xCCNN). Note these CNIs may use different country and network codes than the PDC (VPS, 8/30-2) CNIs.

For example BBC1: 0x447F, ZDF: 0x4902.

examples/network.c.
