conforming to the ETSI 300 294 standard. WSS data is
transmitted on Line 23. WSS data can only be transmitted when
the device is configured in PAL mode. The WSS data is 14 bits
long. The function of each of these bits is shown in Table 54.
The WSS data is preceded by a run-in sequence and a start code
