Okay, sounds like I wasn't technically correct (but then I'm no video engineer)
Found this explanation on Wiki which sounded more like what really happens:
"All mainstream analog and many digital television systems arrange the scan lines of each frame into two consecutive fields, one containing all even lines, another with the odd lines. The fields are then displayed in succession at a rate twice that of the nominal frame rate. For instance, PAL and SECAM systems have a rate of 25 frames/s or 50 fields/s, while the NTSC system delivers 29.97 frames/s or 59.94 fields/s. This process of dividing frames into half-resolution fields at double the frame rate is known as interlacing."
