Info

46 subcell_info_loop_length: This 8-bit field gives the total length in bytes of the following loop that indicates the frequencies used in subcells. cell_id_extension: This 8-bit field is used to identify a subcell within a cell. transposer_frequency: This 32-bit field identifies the frequency that is used by a transposer in the subcell indicated. The coding of the frequency is according to the coding of the centre_frequency in the terrestrial_delivery_system_descriptor. 6.2.7 Cell list descriptor The cell list descriptor (see table 24) may be used in the Network Information Table (NIT) that describes a terrestrial network. It provides a list of all cells of the network about which the NIT sub-table informs and describes their coverage areas.

47 cell_extent_of_longitude: This 12-bit field, coded as an unsigned binary number, shall specify the extent of longitude of a spherical rectangle that approximately describes the coverage area of the cell indicated. It shall be calculated by multiplying the value of the extent_of_longitude field by (180º/2 15 ). subcell_info_loop_length: This 8-bit field gives the total length in bytes of the following loop that describes the subcells. cell_id_extension: This 8-bit field is used to identify a subcell within a cell. subcell_latitude: This 16-bit field, coded as a two's complement number, shall specify the latitude of the corner of a spherical rectangle that approximately describes the coverage area of the subcell indicated. It shall be calculated by multiplying the value of the latitude field by (90º/2 15 ). Southern latitudes shall be considered negative and northern latitudes positive. subcell_longitude: This 16-bit field, coded as a two's complement number, shall specify the longitude of the corner of a spherical rectangle that approximately describes the coverage area of the subcell indicated. It shall be calculated by multiplying the value of the longitude field by (180º/2 15 ). Western longitudes shall be considered negative and eastern longitudes positive. subcell_extent_of_latitude: This 12-bit field, coded as an unsigned binary number, shall specify the extent of latitude of a spherical rectangle that approximately describes the coverage area of the subcell indicated. It shall be calculated by multiplying the value of the extent_of_latitude field by (90º/2 15 ). subcell_extent_of_longitude: This 12-bit field, coded as an unsigned binary number, shall specify the extent of longitude of a spherical rectangle that approximately describes the coverage area of the subcell indicated. It shall be calculated by multiplying the value of the extent_of_longitude field by (180º/2 15 ). 6.2.8 Component descriptor The component descriptor identifies the type of component stream and may be used to provide a text description of the elementary stream (see table 25).
