       <h2>Byte Stream Formats</h2>
       <p>The bytes provided through <a def-id="appendArrayBuffer"></a> and <a def-id="appendStream"></a> for a <a>SourceBuffer</a> form a logical byte stream. The format of this byte stream depends on the media container format in use and is defined in a byte stream format specification. Byte stream format specifications based on WebM , the ISO Base Media File Format, and MPEG-2 Transport Streams are provided below. These format specifications are intended to be the authoritative source for how data from these containers is formatted and passed to a <a>SourceBuffer</a>. If a <a>MediaSource</a> implementation claims to support any of these container formats, then it must implement the corresponding byte stream format specification described below.</p>
