Preliminary speciﬁcation

Integrated Video input processor and

Teletext decoder (IVT1.8*)

SAA5281

ENHANCED MODE

In enhanced mode, the number of extension packets captured is reduced to the minimum required for FASTEXT

operation. The first seven chapters can then be used for storage, using the system of pointers. The arrangement of

extension packets is shown in Fig.11.

When in enhanced mode and extension packets are disabled, normal 8-page mode is in operation, but the X/26 engine

is enabled (unlike normal 8-page mode).
