For an NABTS system, the packet prefix consists of five bytes. Each byte contains 4 data bits
(D[3:0]) interlaced with 4 Hamming protection bits (H[3:0]):

Only data portion D[3:0] from each byte is applied to a teletext filter function with corresponding
pattern bits P[3:0] and mask bits M[3:0] (see Figure 227). The filter ignores the Hamming
protection bits.
For WST system (PAL or NTSC), the packet prefix consists of two bytes. The two bytes contain
three bits of magazine number (M[2:0]) and five bits of row address (R[4:0]), interlaced with eight
Hamming protection bits H[7:0]:

The mask bits enable filtering using the corresponding bit in the pattern register. For example, a
1 in the LSB of mask 1 means that the filter module must compare the LSB of nibble 1 in the
pattern register to the first data bit on the transaction. If these match, then a true result is
returned. A 0 in a mask bit means that the filter module must ignore that data bit of the
transaction. If all 0s are programmed in the mask bits, then the filter matches all patterns
returning a true result (default 00h).
