/**
* This top-level ASF object supplies the necessary indexing information for an
* ASF file that contains more than just a plain script-audio-video combination.
* It includes stream-specific indexing information based on an adjustable index
* entry time interval. The index is designed to be broken into blocks to
* facilitate storage that is more space-efficient by using 32-bit offsets
* relative to a 64-bit base. That is, each index block has a full 64-bit offset
* in the block header that is added to the 32-bit offsets found in each index
* entry. If a file is larger than 2^32 bytes, then multiple index blocks can be
* used to fully index the entire large file while still keeping index entry
* offsets at 32 bits.
*
* Indices into the <i>Index Object</i> are in terms of presentation times. The
* corresponding <i>Offset</i> field values of the <i>Index Entry</i> byte
* offsets that, when combined with the <i>Block Position</i> value of the
* <i>Index Block</i>, indicate the starting location in bytes of an ASF Data
* Packet relative to the start of the first ASF Data Packet in the file.
*
* An offset value of 0xFFFFFFFF is used to indicate an invalid offset value.
* Invalid offsets signify that this particular index entry does not identify a
* valid indexible point. Invalid offsets may occur for the initial index
* entries of a digital media stream whose first ASF Data Packet has a non-zero
* send time. Invalid offsets may also occur in the case where a digital media
* stream has a large gap in the presentation time of successive objects.
*
* The <i>Index Object</i> is not recommended for use with files where the
* <i>Send Time</i> of the first <i>Data Packet</i> within the <i>Data
* Object</i> has a <i>Send Time</i> value significantly greater than zero
* (otherwise the index itself will be sparse and inefficient).
*
* Any ASF file containing an <i>Index Object</i> does also contain an <i>Index
* Parameters Object</i> in its {@link ASF_Object_Header ASF Header}.

* This top-level ASF object supplies media object indexing information for the
* streams of an ASF file. It includes stream-specific indexing information
* based on an adjustable index entry media object count interval. This object
* can be used to index all the video frames or key frames in a video stream.
* The index is designed to be broken into blocks to facilitate storage that is
* more space-efficient by using 32-bit offsets relative to a 64-bit base. That
* is, each index block has a full 64-bit offset in the block header that is
* added to the 32-bit offset found in each index entry. If a file is larger
* than 2^32 bytes, then multiple index blocks can be used to fully index the
* entire large file while still keeping index entry offsets at 32 bits.
*
* Indices into the <i>Media Object Index Object</i> are in terms of media
* object numbers, with the first frame for a given stream in the ASF file
* corresponding to entry 0 in the <i>Media Object Index Object</i>. The
* corresponding <i>Offset</i> field values of the <i>Index Entry</i> are byte
* offsets that, when combined with the <i>Block Position</i> value of the
* Index Block, indicate the starting location in bytes of an ASF Data Packet
* relative to the start of the first ASF Data Packet in the file.
*
* Any ASF file containing a <i>Media Object Index Object</i> shall also contain
* a <i>Media Object Index Parameters Object</i> in its

/**
* This top-level ASF object supplies timecode indexing information for the
* streams of an ASF file. It includes stream-specific indexing information
* based on the timecodes found in the file. If the <i>Timecode Index Object</i>
* is used, it is recommended that timecodes be stored as a <i>Payload Extension
* System</i> on the appropriate stream. It is also recommended that every
* timecode appearing in the ASF file have a corresponging index entry.
*
* The index is designed to be broken into blocks to facilitate storage that is
* more space-efficient by using 32-bit offsets relative to a 64-bit base. That
* is, each index block has a full 64-bit offset in the block header that is
* added to the 32-bit offsets found in each index entry. If a file is larger
* than 2^32 bytes, then multiple index blocks can be used to fully index the
* entire large file while still keeping index entry offsets at 32 bits.
*
* To locate an object with a particular timecode in an ASF file, one would
* typically look through the <i>Timecode Index Object</i> in blocks of the
* appropriate range and try to locate the nearest possible timecode. The
* corresponding <i>Offset</i> field values of the <i>Index Entry</i> are byte
* offsets that, when combined with the <i>Block Position</i> value of the Index
* Block, indicate the starting location in bytes of an ASF Data Packet relative
* to the start of the first ASF Data Packet in the file.
*
* Any ASF file containing a <i>Timecode Index Object</i> shall also contain a
* <i>Timecode Index Parameters Object</i> in its
* {@link ASF_Object_Header ASF Header}.
