Non-linear Navigation Key for Channel Grouping

The patent transforms the linear one-dimensional arrangement of channel keys into a two-dimensional grid layout. Instead of arranging keys in a single row, the keys are organized in multiple rows and columns, allowing users to access channels more efficiently by navigating through rows and columns rather than sequentially pressing through all channels. This dimensional change reduces the maximum number of key presses required to reach any channel.

The patent divides the large set of hundreds of channels into smaller groups arranged in a grid structure. By segmenting the channel keys into multiple rows and columns, the system creates manageable sections that users can navigate more efficiently. This segmentation allows users to reach any channel with fewer manipulations compared to a linear arrangement where users must press through all preceding channels.

The patent applies dimensional change by organizing channel selection in a two-dimensional grid rather than a linear sequence. This allows users to navigate to any channel position (row, column) more directly, reducing the time required to access channels even when hundreds of channels are available. The grid structure enables faster navigation compared to sequential linear progression.

The patent performs preliminary organization of channels into a structured grid layout before user interaction. By pre-arranging channels in rows and columns with logical groupings, the system prepares the channel structure in advance, allowing users to quickly locate and select channels without time-consuming sequential searching through hundreds of channels.
