    • A method for transferring multimedia information in a system including a primary site 101 and at least one satellite site 102 coupled to the primary site 101 by a transmission medium 103. Information defining each of a selected plurality of objects composing a multimedia presentation is compressed at primary site 101 using a compression/decompression protocol corresponding to a type of each of the objects. The compressed information is transferred to satellite site 102 from primary site 101 via medium 103. Scene information describing the multimedia presentation to be made from the objects is also transferred from primary site 101. The compressed information defining each of the objects is decompressed at satellite 102 using the corresponding compression/decompression protocol. The multimedia presentation composed of the selected objects is generated at satellite site 102 from the decompressed information as directed by the received scene information.
    • 一种用于在包括主站点101和至少一个卫星站点102的系统中传送多媒体信息的方法,所述至少一个卫星站点102通过传输介质103耦合到主站点101。定义组成多媒体呈现的所选择的多个对象中的每一个的信息被压缩在主要站点 站点101使用对应于每个对象的类型的压缩/解压缩协议。 压缩信息经由介质103从主站点101传送到卫星站点102.描述从对象进行的多媒体呈现的场景信息也从主站点101传送。定义每个对象的压缩信息在卫星102处被解压缩 使用相应的压缩/解压协议。 由所选择的对象组成的多媒体呈现是根据接收到的场景信息的指示从解压缩信息在卫星站点102生成的。
