Contains information about an MPEG-2 descriptor.

Syntax

typedef struct _SpanningEventDescriptor {
  WORD wDataLen;
  WORD wProgNumber;
  WORD wSID;
  BYTE bDescriptor[1];
} SpanningEventDescriptor;

Members

wDataLen

Total size of the structure in bytes, including the size of the bDescriptor array.

wProgNumber

The program number associated with the descriptor.

wSID

The service ID associted with the descriptor.

bDescriptor

A byte array with the following layout:

• Byte 0 contains the descriptor tag.
• Byte 1 contains the length of the descriptor body.
• The remaining bytes contain the descriptor body.

The array is larger than the size given in the structure declaration. Use the value of wDataLen to determine the size.
