DATAQUEST ANALYSIS<br />

Evolution of MAC<br />

We expect MAC to follow a step-by-step evolution in Europe, as shown in Figure 1.<br />

The first step begins this year when subscribers connect conventional PAL or SECAM<br />

sets to MAC adaptors to receive U.K. BSB and French TDF-1 satellite channels. MAC<br />

adaptors also will be needed to receive the new cable television networks, mainly in<br />

France and West Germany. By the end of 1990, manufacturers will have incorporated<br />

MAC decoders into their receivers and, by 1992, we expect wide-screen versions to be<br />

available. The appearance of high-definition HD-MAC receivers in the mid-1990s will<br />

mark the final stage in MAC's development. These high-definition receivers will use<br />

light projection in place of CRT displays to allow large-screen viewing without adding<br />

bulk to the receiver.<br />
