This command links to the next PGC within the same domain and optionally highlights a specified menu button. A button value of 0 indicates no highlight. PGCs within a domain are numbered from 1. In the title domain, each PGC is mapped to a title number and can be accessed from the VMG or another VTS or VTSM domain via the entry PGC of the specified title. Each title has only one entry PGC and only this PGC can be accessed directly. To access other (non-entry) PGCs in the title from a different domain, virtual commands must be present in the precommand section of the entry PGC to route access requests to other PGCs in the same title.

The DVD specifications support a maximum of 999 PGCs per VTS and up to 36 highlight buttons per display menu. For practical purposes, most authoring packages limit a VTS to 256 PGCs or fewer.

LinkNextPGC can connect two arbitrary PGCs together so that when one PGC completes playing, the other PGC begins playing automatically. The PGC data structure has a NextPGC field to define any PGC in the same domain as the next PGC. This can be used to take advantage of the functions built into the DVD remote control. The Next button on a DVD player's remote control directs playback of the last cell to the next PGC that is connected to the current PGC via the NextPGC field.

Cells having cell commands are non-seamless by default. LinkNextPGC can be present only in cell or button commands. LinkNextPGC cannot be present in the First-Play domain.

This command can be combined with the Compare GPRM operations for conditional branching. When combining, this command is executed only if the result of the comparison is true.

1) Compare to another GPRM register and LinkNextPGC
2) Compare to another SPRM register and LinkNextPGC
3) Compare to a constant value and LinkNextPGC
4) SetGPRM and LinkNextPGC
