摘要： In an illustrative embodiment, an audio/video conferencing system comprises two or more audio/video terminals, in which the transmitted and/or received audio is automatically adjusted to provide synchronization between audio and video during periods of monologue (i.e., single talker active for significant duration). During interactive periods in which more than one talker is active, the audio delay is automatically adjusted to be less than the video delay, thus improving audio conference quality.

摘要： An apparatus and method enables a user to control the selection of electronic multimedia services to be provided to the user by one or more servers over a communication medium. The apparatus includes a scanner for reading marks on an object and for communicating a request signal, having an object code representing the read marks, to a user interface. The interface receives the request signal and transmits to the servers a request command including an interface identification code and the object code which is used to select the desired electronic multimedia service. The servers identify the selected electronic multimedia service using the object code. The interface then enables the selected electronic multimedia service transmitted from the servers to be received by the user's receiver.
摘要翻译：一种装置和方法使得用户能够通过通信介质来控制由一个或多个服务器提供给用户的电子多媒体服务的选择。该装置包括用于在对象上读取标记并将具有表示读取标记的目标代码的请求信号传送到用户界面的扫描器。该接口接收请求信号，并向服务器发送包括用于选择所需电子多媒体业务的接口标识码和目标码的请求命令。服务器使用目标代码识别所选择的电子多媒体服务。然后，接口使得从服务器发送的所选择的电子多媒体服务能够被用户的接收者接收。
