Each packet consists of a header and after that RLE-encoded data. The header starts with timing information in the format (27 bytes, no terminating zero): </p> <pre>[HH:MM:ss.mmm-HH:MM:ss.mmm] </pre> <p>Then, encoded as 16 bit little-endian except for the color entries, follow: </p> <pre>width of encoded image height of encoded image x coordinate of top left subtitle corner y coordinate of top left subtitle corner x coordinate of bottom right subtitle corner y coordinate of bottom right subtitle corner length of the RLE data four color entries (red, green, blue, eight bits per component, unsigned) </pre> <p>Width, height and coordinates probably all must be a multiple of 2. It is unclear what the behavior is if the coordinates are not consistent with width and height, the encoder does not produce such files. </p><p>After this follows the RLE-encoded data. </p><p>This is processed 4 bits at a time, big-endian bitstream order (lowest byte address first, within that byte highest bits first). </p><p>Encoding is n bits run-length followed by 2 bits color (index into four color palette in header), where n can be 2, 6, 10, or 14 (yes, it is a very weird and probably suboptimal encoding). </p><p>n can be determined via the number of leading zeros: </p> <pre>leading zeros | n | possible length values 0 - 1 2 1 - 3 2 - 3 6 4 - 15 4 - 5 10 16 - 63 6 - 7 14 64 - 255 > 7 14 must be == 0 and means the remainder of the row has this color </pre> <p>After each row the bitstream is byte-aligned. </p>    </div> <div class="printfooter" data-nosnippet="">Retrieved from "<a dir="ltr" href="https://wiki.multimedia.cx/index.php?title=XSUB&oldid=10542">https://wiki.multimedia.cx/index.php?title=XSUB&oldid=10542</a>"</div></div> <div id="catlinks" class="catlinks" data-mw="interface"><div id="mw-normal-catlinks" class="mw-normal-catlinks"><a href="/index.php/Special:Categories" title="Special:Categories">Category</a>: <ul><li><a href="/index.php/Category:Subtitle_Formats" title="Category:Subtitle Formats">Subtitle Formats</a></li></ul></div></div> </div> </div> <div id="mw-navigation"> <h2>Navigation menu</h2> <div id="mw-head"> <nav id="p-personal" class="vector-menu mw-portlet mw-portlet-personal vector-user-menu-legacy" aria-labelledby="p-personal-label" role="navigation" > <h3 id="p-personal-label" class="vector-menu-heading " > <span class="vector-menu-heading-label">Personal tools</span> </h3> <div class="vector-menu-content"> <ul class="vector-menu-content-list"><li id="pt-login" class="mw-list-item"><a href="/index.php?title=Special:UserLogin&returnto=XSUB&returntoquery=oldid%3D10542" title="You are encouraged to log in; however, it is not mandatory [o]" accesskey="o"><span>Log in</span></a></li></ul> </div> </nav> <div id="left-navigation"> <nav id="p-namespaces" class="vector-menu mw-portlet mw-portlet-namespaces vector-menu-tabs vector-menu-tabs-legacy" aria-labelledby="p-namespaces-label" role="navigation" > <h3 id="p-namespaces-label" class="vector-menu-heading " > <span class="vector-menu-heading-label">Namespaces</span> </h3> <div class="vector-menu-content"> <ul class="vector-menu-content-list"><li id="ca-nstab-main" class="selected mw-list-item"><a href="/index.php/XSUB" title="View the content page [c]" accesskey="c"><span>Page</span></a></li><li id="ca-talk" class="new mw-list-item"><a href="/index.php?title=Talk:XSUB&action=edit&redlink=1" rel="discussion" title="Discussion about the content page (page does not exist) [t]" accesskey="t"><span>Discussion</span></a></li></ul> </div> </nav> <nav id="p-variants" class="vector-menu mw-portlet mw-portlet-variants emptyPortlet vector-menu-dropdown" aria-labelledby="p-variants-label" role="navigation" > <input type="checkbox" id="p-variants-checkbox" role="button" aria-haspopup="true" data-event-name="ui.dropdown-p-variants" class="vector-menu-checkbox" aria-labelledby="p-variants-label" /> <label id="p-variants-label" aria-label="Change language variant" class="vector-menu-heading " > <span class="vector-menu-heading-label">English</span> </label> <div class="vector-menu-content"> <ul class="vector-menu-content-list"></ul> </div> </nav> </div> <div id="right-navigation"> <nav id="p-views" class="vector-menu mw-portlet mw-portlet-views vector-menu-tabs vector-menu-tabs-legacy" aria-labelledby="p-views-label" role="navigation" > <h3 id="p-views-label" class="vector-menu-heading " > <span class="vector-menu-heading-label">Views</span> </h3> <div class="vector-menu-content"> <ul class="vector-menu-content-list"><li id="ca-view" class="selected mw-list-item"><a href="/index.php/XSUB"><span>Read</span></a></li><li id="ca-viewsource" class="mw-list-item"><a href="/index.php?title=XSUB&action=edit" title="This page is protected.
