摘要： Apparatus for providing a user friendly interface to a subscription television terminal comprises a key pad arranged into a plurality of key groupings and an on-screen display controller for generating a plurality of screens for display on an associated television receiver. Five such key groupings are segregated from one another and comprise function keys, initialization keys, channel keys, audio keys and digit keys. The digit keys may be most conveniently arranged in a two dimensional matrix corresponding to a key pad of a conventional tone dialing telephone. Each of the other key groupings may be arranged linearly and differentiated by the use of color or boxes. A method of initializing the cable television terminal comprises the steps of generating a display of a menu structure, actuating the movement of a cursor in one direction through choices presented by a menu by use of a cursor key, and actuating a selection of a menu choice via actuation of a select key. For example, a sleep timer may be implemented in a subscription television terminal for turning off power to an associated television set after a predetermined period of time. Parental control of received channels can be established such that only those having knowledge of a particular code may view the parentally controlled channel. Other features of a terminal in accorance with the invention include messaging, establishing a favorite channel list, pay-per-view, program timing, and terminal control.
摘要翻译：用于向订阅电视终端提供用户友好界面的设备包括布置成多个密钥分组的键盘和用于生成用于在相关联的电视接收机上显示的多个屏幕的屏幕显示控制器。五个这样的密钥分组彼此隔离，包括功能键，初始化键，通道键，音频键和数字键。数字键可以最方便地布置在与常规音调拨号电话的键盘相对应的二维矩阵中。每个其他键组可以线性排列，并通过使用颜色或框来区分。一种初始化有线电视终端的方法包括以下步骤：产生菜单结构的显示，通过使用光标键，通过菜单所呈现的选择来促使光标在一个方向上的移动，以及启动菜单选择的选择通过选择键的启动。例如，睡眠定时器可以在订阅电视终端中实现，用于在预定时间段之后关闭相关电视机的电力。可以建立所接收的信道的家长控制，使得仅具有特定代码的知识的人可以查看父母控制的信道。根据本发明的终端的其他特征包括消息传递，建立喜好频道列表，按次付费，节目定时和终端控制。
