1. A method of a reception apparatus for accessing content, comprising: receiving a transport stream from a content provider; extracting, by circuitry of the reception apparatus, a virtual channel table (VCT) from the transport stream; and when a virtual channel defined in the VCT is associated with a predetermined Service Type for an extended parameterized service that conveys a parameterized service descriptor (PSD), determining whether a component list descriptor (CLD) is included for the virtual channel in the VCT, and determining, by the circuitry, whether one or more services corresponding to the virtual channel is supported by the reception apparatus based on the PSD included in the VCT, wherein the PSD has a bit-stream syntax that is different from a bit-stream syntax of the component list descriptor (CLD).
