    • A system and method for enabling television watchers to “channel surf” faster and reduce the amount of bandwidth used over a network to communicate television channels to end-users. Electronic programming guide information and images associated therewith may be communicated to an end-user. An image associated with a video program may be displayed on an electronic display (e.g., television) in response to an end-user selecting a channel prior to video programming being displayed. By displaying an image prior to the video programming, the end-user may determine whether he or she wants to watch the video program prior to the video programming being displayed, which improves the speed of “channel surfing.” Because end-users can view the image when selecting a channel, a network can be configured to distribute the channels that are currently being watched rather than distributing many on a continuous basis, thereby preserving bandwidth.
    • 一种用于使电视观看者能够更快地“频繁冲浪”并减少通过网络使用的带宽量以向最终用户传送电视频道的系统和方法。 与其相关联的电子节目指南信息和图像可以被传送给终端用户。 响应于最终用户在显示视频节目之前选择频道,可以在电子显示器(例如,电视机)上显示与视频节目相关联的图像。 通过在视频编程之前显示图像,最终用户可以在显示视频节目之前确定他或她是否想要观看视频节目,这提高了“频道冲浪”的速度。 因为最终用户可以在选择频道时查看图像,因此可以将网络配置为分发当前正在观看的频道,而不是连续分发多个频道,从而保留带宽。
