Authoring includes 114 the creation of the media bitstream plus the creation of 115 annotations (i.e. textual data descriptions), indexes 116 (i.e. anchor points) and hyperlinks (i.e. <xref 117 target="URI">URIs</xref>) for clips of the media 118 data. Annotations, indexes and hyperlinks are created in 119 "head" and "clip" tags conformant to the CMML specification, and 120 interleaved into the media document to create 121 Annodex format bitstreams in a time-synchronous 122 fashion. This procedure can be performed both on files and live 123 streams. The collection of Annodex format bitstreams on the 124 Internet is called the Continuous Media Web as it builds a Web 125 of time-continuous resources. 126 </t> 127 128 <t>To access the Continuous Media Web, a client such as a 129 conformant Web browser is required. A client can link to an 130 Annodex bitstream via a URI. A URI can point to a temporal 131 offset in the Annodex bitstream using <xref 132 target="timedURI">URI time interval specifierss</xref> or to 133 a named offset by using the id tag of a clip element as a URI 134 fragment identifier. In this way, direct access to points of 135 interest in the media document is enabled. While playing back 136 Annodex format bitstreams, a user is being offered 137 hyperlinks (URIs) to other Web resources which 138 are related to the currently displayed media content. 139 </t> 140 141 <t>A client may be a special player or a browser plugin. This 142 application must split an Annodex format bitstream into its 143 constituent time-continuous data streams and the annotation 144 bitstream consisting of "head" and "clip" tags. A 145 decoder is required to display the encapsulated media document 146 after decoding it with the appropriate media decoder. While 147 playing back the media document, the application displays the 148 hyperlinks and the annotations for the active clips. 149 </t> 150 151 <t>Search engines can include published Annodex format files 152 into their search repertoire by finding annotations in the 153 clip tags in a standard way independent of the encoding and 154 packetising format of the annodexed time-continuous data 155 streams. This allows any media 156 format to be spidered. In addition, the protocol should allow the 157 downloading of only the CMML mark-up from a published Annodex 158 format file in order to discourage spiders from creating extensive 159 network loads, as they do not need to download the media 160 bitstream to gain the necessary information. It also reduces the 161 size of search archives, even for large amounts of published 162 Annodex format files, because a CMML file contains all 163 searchable annotations for the clips of its 164 Annodex format file. 165 </t> 166 167 </section> 168 169 170 <!--**************--> 171 <!-- INTRODUCTION --> 103 <!-- Introduction --> 172 104 <!--**************--> 173 105 <section title="Introduction"> 174 175 <t>Please note that this document assumes that the reader has a176 fluent working knowledge of <xref target="XML">Extensible Markup177 Language (XML)</xref>, <xref target="HTML">Hypertext Markup178 Language (HTML)</xref>, <xref target="XHTML">XHTML</xref> and179 the World Wide Web.

Authoring includes116 the creation of the media bitstream plus the creation of117 annotations (i.e. textual data descriptions), indexes118 (i.e. anchor points) and hyperlinks (i.e. <xref119 target="URI">URIs</xref>) for clips of the media120 data. Annotations, indexes and hyperlinks are created in121 "head" and "clip" tags conformant to the CMML specification, and122 interleaved into the media document to create123 Annodex format bitstreams in a time-synchronous124 fashion. This procedure can be performed both on files and live125 streams. The collection of Annodex format bitstreams on the126 Internet is called the Continuous Media Web as it builds a Web127 of time-continuous resources.128 </t>129 130 <t>To access the Continuous Media Web, a client such as a131 conformant Web browser is required. A client can link to an132 Annodex bitstream via a URI. A URI can point to a temporal133 offset in the Annodex bitstream using <xref134 target="timedURI">URI time interval specifierss</xref> or to135 a named offset by using the id tag of a clip element as a URI136 fragment identifier. In this way, direct access to points of137 interest in the media document is enabled. While playing back138 Annodex format bitstreams, a user is being offered139 hyperlinks (URIs) to other Web resources which140 are related to the currently displayed media content.141 </t>142 143 <t>A client may be a special player or a browser plugin. This144 application must split an Annodex format bitstream into its145 constituent time-continuous data streams and the annotation146 bitstream consisting of "head" and "clip" tags. A147 decoder is required to display the encapsulated media document148 after decoding it with the appropriate media decoder. While149 playing back the media document, the application displays the150 hyperlinks and the annotations for the active clips.151 </t>152 153 <t>Search engines can include published Annodex format files154 into their search repertoire by finding annotations in the155 clip tags in a standard way independent of the encoding and156 packetising format of the annodexed time-continuous data157 streams. This allows any media158 format to be spidered. In addition, the protocol should allow the159 downloading of only the CMML mark-up from a published Annodex160 format file in order to discourage spiders from creating extensive161 network loads, as they do not need to download the media162 bitstream to gain the necessary information. It also reduces the163 size of search archives, even for large amounts of published164 Annodex format files, because a CMML file contains all165 searchable annotations for the clips of its166 Annodex format file.167 </t>168 169 </section>170 171 172 <!--**************-->173 103 <!-- INTRODUCTION --> 174 104 <!--**************--> 175 105 <section title="Introduction"> 176 177 <t>Please note that this document assumes that the reader has a178 fluent working knowledge of <xref target="XML">Extensible Markup179 Language (XML)</xref>, <xref target="HTML">Hypertext Markup180 Language (HTML)</xref>, <xref target="XHTML">XHTML</xref>,181 <xref target="CSS">Cascading Style Sheets (CSS)</xref> and182 the World Wide Web.
