摘要： In a multilocation video conference system, contention for the video to be transmitted to the locations is resolved by employing so-called talker and graphics contention resolution processes. Both the talker and graphics contention processes may be overridden by manual selection of the video to be viewed at each location. In the talker contention process, the video to be transmitted is not switched until one and only one talker location is detected during a predetermined talker timing interval. In the graphics contention process, all requests for graphics transmission are rejected until one and only one graphics transmission request is detected during a predetermined graphics request timing interval. Once transmission of graphics has been assigned to a location, all other locations in the conference are transmitted the graphics video information until the location displaying graphics releases from the graphics transmission mode or there is a manual override. The location transmitting graphics information is transmitted the video from the last of the other locations selected for talker video transmission.

摘要： In a multilocation video conference system, conference locations are dynamically added to or deleted from an ongoing conference without disrupting it. This is realized by controllably enabling or disabling communications ports assigned to the conference locations in a Multilocation Conference Terminal (MLCT). Both audio information and control channel information transmitted from a conference location assigned to a port are monitored to determine if the audio information is satisfactory and if the control channel communication is "good". If the audio information is unsatisfactory, it is muted and selection of the video from that location as a one-and-only-one talker is inhibited. If the control channel communication is not good the video signal from the conference location is excluded from the conference.
摘要翻译：在多位置视频会议系统中，会议位置被动态添加到正在进行的会议中或从正在进行的会议中删除，而不会中断会议。这通过可控地启用或禁用分配给多位置会议终端（MLCT）中的会议位置的通信端口来实现。监视从分配给端口的会议位置发送的音频信息和控制信道信息，以确定音频信息是否令人满意，并且控制信道通信是否“良好”。如果音频信息不令人满意，则它被静音，并且从该位置的视频作为一对一的讲话者被禁止。如果控制信道通信不好，会议位置的视频信号被排除在会议之外。

摘要： A smooth pulse sequence (SSM) which is a rational fraction (M/N) of an available uniform sequence (SIN) is generated by employing an address generator (10) and a read only memory (ROM 15). Signal representations are stored in the ROM (15) which define the smooth sequence pulse transitions. The address generator (10) is driven by the reference signal and, in turn, generates a sequence of address signals which, when applied to the ROM (15) cause the smooth pulse sequence (SSM) to be read out. The smooth pulse sequence (SSM) is filtered (16) and shaped (17) to obtain a desired uniform pulse sequence (SOUT) which is in synchronism with the reference signal (SIN).
