[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]

Gets a conditional access unit identifier from a specified component group record in an Integrated Services Digital Broadcasting (ISDB) component group descriptor. This identifier specifies the type of conditional access unit group to which the component belongs.

HRESULT GetRecordCAUnitCAUnitId(
  [in]  BYTE bRecordIndex,
  [in]  BYTE bCAUnitIndex,
  [out] BYTE *pbVal
