1.1 Glossary

This document uses the following terms:

.nsc file: A file that serves as an announcement for, and contains information about, a media stream broadcast. This file allows a client to tune in to a broadcast. The .nsc file was originally known as a NetShow Station Configuration file. Because the NetShow protocol suite is now obsolete, the original nomenclature is no longer applicable and is not used. Also known as a Windows Media Station file or an NSC file.

Advanced Systems Format (ASF): An extensible file format that is designed to facilitate streaming digital media data over a network. This file format is used by Windows Media.

HRESULT: An integer value that indicates the result or status of an operation. A particular HRESULT can have different meanings depending on the protocol using it. See [MS-ERREF] section 2.1 and specific protocol documents for further details.

little-endian: Multiple-byte values that are byte-ordered with the least significant byte stored in the memory location with the lowest address.

parity packet: An ASF data packet that contains parity data and is used for reconstructing other lost packets. Unlike other ASF data packets, parity packets always have the Opaque Data Present bit set to 1 in the ASF data packet header.

MAY, SHOULD, MUST, SHOULD NOT, MUST NOT: These terms (in all caps) are used as defined in [RFC2119]. All statements of optional behavior use either MAY, SHOULD, or SHOULD NOT.
