<p class="short-description">The <em>Independent and Disposable Samples Box</em> optional table answers</p>
<p class="description"><p>three questions about sample dependency: 1) does this sample depend on others (is it an I-picture)? 2) do no other samples depend on this one? 3) does this sample contain multiple (redundant) encodings of the data at this time-instant (possibly with different dependencies)?</p><p>In the absence of this table: 1) the sync sample table answers the first question; in most video codecs, I-pictures are also sync points, 2) the dependency of other samples on this one is unknown. 3) the existence of redundant coding is unknown.</p><p>When performing trick modes, such as fast-forward, it is possible to use the first piece of information to locate independently decodable samples. Similarly, when performing random access, it may be necessary to locate the previous sync point or random access recovery point, and roll-forward from the sync point or the pre-roll starting point of the random access recovery point to the desired point. While rolling forward, samples on which no others depend need not be retrieved or decoded.</p><p>The value of sampleIsDependedOn is independent of the existence of redundant codings. However, a redundant coding may have different dependencies from the primary coding; if redundant codings are available, the value of sampleDependsOn documents only the primary coding.</p><p>A sample dependency Box may also occur in the <a href="../../php-reader/ISO/ISO14496_Box_TRAF.html">Track Fragment Box</a>.</p></p>
