Abstract
A transmission apparatus is disclosed. The present transmission apparatus, for each PLP, comprises: a frame builder which calculates the size of a subslice based on the number of cells of the PLP to be transmitted in one subframe and the number of predetermined subslices, compares a value calculated based on the size of the subslices and the number of the subslices with the number of cells of the PLP to determine whether to insert the dummy cell, and maps a cell of the PLP included in the subslice to a subframe; and a transmission unit for transmitting the subframe to a reception apparatus, and at least one of the subslices may comprise a dummy cell depending on whether the dummy cell is inserted.
Claims15
A transmission apparatus for multiplexing cells of a plurality of physical layer pipes (PLPs), the transmission apparatus comprising:
- a frame builder configured to:
- for each PLP, based on a number of cells of the PLP to be transmitted in one subframe and a number of predetermined subslices, calculate a size of a subslice from among the subslices, calculate a value based on the size of the subslice and the number of the subslices, determine a number of the cells of the PLP, compare the calculated value with the determined number to determine whether to insert a dummy cell, and map a cell of the PLP included in the subslice to a subframe;
- and
- a transmission unit for transmitting the subframe to a reception apparatus,
- wherein at least one of the subslices comprises the dummy cell depending on whether the dummy cell is inserted.
A method for multiplexing of cells of a plurality of physical layer pipes (PLPs), the method comprising:
- for each PLP, based on a number of cells of the PLP to be transmitted in one subframe and a number of predetermined subslices, calculating a size of a subslice from among the subslices;
- comparing a value calculated based on the size of the subslice and the number of the subslices with a number of the cells of the PLP to determine whether to insert a dummy cell;
- and
- mapping a cell of the PLP included in the subslice to a subframe,
- wherein at least one of the subslices comprises the dummy cell depending on whether the dummy cell is inserted.
A reception apparatus for demultiplexing cells of a plurality of PLPs, the apparatus comprising:
- a reception unit for receiving a subframe from a transmission apparatus;
- and
- a frame de-builder configured to:
- for each PLP, based on a number of cells of the PLP to be transmitted through one subframe and a number of a predetermined subslices, calculate a size of a subslice from among the subslices, calculate a value based on the size of the subslice and the number of the subslices, determine a number of the cells of the PLP, compare the calculated value with the determined number to determine whether a dummy cell is inserted in the subframe, and based on the dummy cell being inserted, de-map the cells of the PLP from the subframe excluding the dummy cell.
