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, anddetermining, 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, whereinthe PSD has a bit-stream syntax that is different from a bit-stream syntax of the component list descriptor (CLD).

Abstract
A method, computer program, reception apparatus, and information providing apparatus for accessing or providing access to content. The method includes receiving a transport stream from a content provider. A virtual channel table (VCT) is extracted from the transport stream. Further, a determination is made as to whether one or more services, corresponding to an entry included in the VCT, are supported by the reception apparatus based on one or more parameterized service descriptor (PSD) instances, which are associated with a predetermined Service Type and included in the VCT.

6. A non-transitory computer-readable storage medium having embedded therein instructions, which when executed by a computer, causes the computer to perform a method for accessing content, the method comprising:
-
receiving a transport stream from a content provider; extracting 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 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).

7. A reception apparatus, comprising:
circuitry configured to receive a transport stream from a content provider; extract 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), determine whether a component list descriptor (CLD) is included for the virtual channel in the VCT, and determine 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). - View Dependent Claims (8, 9, 10, 11)

12. An information providing apparatus, comprising:
circuitry configured to store or receive content; encode the content; generate a transport stream including the encoded content and a virtual channel table (VCT), the VCT including a parameterized service descriptor (PSD) for a virtual channel associated with a predetermined Service Type of an extended parameterized service; and when a component list descriptor (CLD) is included for the virtual channel in the VCT, the PSD has a bit-stream syntax that is different from a bit-stream syntax of the component list descriptor (CLD).
