    • A video control user interface is provided for use in an interactive television system. The video control user interface includes a remote control handset with a multi-purpose, multi-direction actuation pad and a set-top box configured to operate in different modes, including a movie-on-demand mode. In this mode, the set-top box receives digitally transmitted video data streams of a selected movie from a centralized head end server. During display of a video movie, the set-top box can cause, at the viewer's request, the television to display an icon representing a physical layout of the actuation pad on the remote control handset and one or more symbols arranged at locations relative to the icon. The symbols relate to shuttle controls for controlling viewing of the video movie. This user interface presents an intuitive visual mapping of the shuttle controls about the depicted icon onto physical actuation positions of the multi-direction pad on the remote control handset. When the viewer wishes to change the viewing mode (such as from "play" to "pause"), the viewer simply depresses the pad at an actuation position that corresponds to a desired shuttle control symbol arranged at approximately the same location relative to the pad-resembling icon that is displayed on the screen. This user interface provides intuitive video control using a multi-purpose actuator, thereby eliminating the need for dedicated shuttle control buttons on the remote control handset.
    • 视频控制用户界面被提供用于交互式电视系统。 视频控制用户界面包括具有多用途多向操作板和机顶盒的遥控手持机,该机顶盒被配置成以包括电影点播模式的不同模式操作。 在这种模式中,机顶盒从集中式头端服务器接收所选影片的数字传输视频数据流。 在显示视频电影期间,机顶盒可以根据观众的要求导致电视机显示表示遥控手机上的操作板的物理布局的图标,以及布置在相对于该遥控器手柄的位置处的一个或多个符号 图标。 这些符号涉及用于控制视频电影观看的班车控制。 该用户界面呈现了关于所描绘的图标的梭子控制的直观视觉映射到遥控手柄上的多方向垫的物理致动位置。 当观众希望改变观看模式(例如从“播放”到“暂停”)时,观众简单地按下与对应于相对于衬垫大致相同位置布置的所需穿梭控制符号的致动位置的按键 - 屏幕上显示的 - 组合图标。 该用户界面使用多用途致动器提供直观的视频控制,从而不需要遥控手持机上的专用梭子控制按钮。

    • An interactive entertainment network system supplies previews in an analog format while operating in a video-on-demand (VOD) mode. The previews are displayed instantaneously when a viewer switches to a designated VOD channel. The previews are played in a continuous loop to attract viewers that are switching through channels. The VOD channel therefore appears like traditional broadcast channels, as opposed to a still screen. In this manner, the viewer will be less inclined to skip past the VOD channel. If the viewer does nothing, the previews of the new releases cycle through, one after another. No digital resources are utilized to this point; rather, the analog video stream is continually transmitted in a "broadcast" fashion. However, if the viewer actively requests information or a new set of previews while in the VOD application, the system ceases the analog presentation and transitions to a fully interactive digital system. Any requested programs or other information is supplied from the headend in a digital format. After a period of inactivity, the system reverts to playing the analog video stream of previews to further conserve digital resources.
    • 交互式娱乐网络系统以视频点播(VOD)模式运行时,以模拟格式提供预览。 当观众切换到指定的VOD频道时,预览将立即显示。 预览会以连续的循环播放,以吸引正在切换频道的观众。 因此,视频点播通道看起来像传统的广播频道,而不是静态屏幕。 以这种方式,观众将不太倾向于跳过VOD频道。 如果观众没有做任何事情,新版本的预览会相继循环。 至此没有使用数字资源; 相反,模拟视频流以“广播”方式不断地传送。 然而,如果观众在VOD应用中主动地请求信息或新的预览集,则系统停止模拟演示并转换到完全交互的数字系统。 任何所请求的程序或其他信息都是从头端以数字格式提供的。 经过一段时间的不活动,系统恢复播放模拟视频流的预览,以进一步节省数字资源。
