<p class="short-description">For each video stream in an ASF file, there should be one instance of the <em>Simple Index Object</em>. Additionally, the instances of the <em>Simple
Index Object</em> shall be ordered by stream number.</p>
<p class="description"><p>Index entries in the <em>Simple Index Object</em> are in terms of <em>Presentation Times</em>. The corresponding <em>Packet Number</em> field values (of the <em>Index Entry</em>, see below) indicate the packet number of the ASF <em>Data Packet</em> with the closest past key frame. Note that for video streams that contain both key frames and non-key frames, the <em>Packet
Number</em> field will always point to the closest past key frame.</p></p>
