Abstract
Aspects of the invention are directed to a cell-frequency-link descriptor configured to map network-specific parameters with time frequency slicing (TFS) information in a digital video broadcast system. The cell-frequency-link descriptor may include fields that provide a mapping between a cell identifier, a TFS group identifier, a bandwidth, a guard interval, a transmission mode, and a frequency. The fields may provide a mapping between cells, frequencies, TFS groups, related guard intervals, bandwidths, and transmission modes for multiple cells within the digital video broadcast system. The fields may include: a cell identifier field, a TFS-group identifier field, a bandwidth field, a guard interval field, a transmission mode field, a frequency field, a cell identifier extension field, and a transposer frequency field.
