    摘要： A digital broadcast system includes: a provider, such as a host station, that broadcasts a digital program and provides a service related to a digital broadcast; a receiving device that receives the digital program; and at least one operating device that can be carried with by a viewer and functions as a remote control of the receiving device and as a portable phone. To provide a service for a program offering prizes to viewers, for instance, the host station broadcasts predetermined control information with the program. While receiving and presenting this program, the receiving device automatically sends the ID information specifying the program via an IR signal to each operating device in the periphery. The operating device attaches its phone number to the ID information and sends it via a telephone line to the provider. The provider registers a combination of the ID information and the phone number without registering the same combination more than once. At a certain time, the provider selects one combination out of registered combinations and phones the phone number in the selected combination to notify the operating device that a prize has been won. The provider can provide other services such as enabling a viewer to join in a quiz show, or sending information to allow viewing of scrambled programs without viewers needing to perform complex operations.

    摘要翻译： 数字广播系统包括：广播数字节目并提供与数字广播有关的服务的诸如主机站的提供者; 接收数字节目的接收装置; 以及可由观看者携带并用作接收设备的遥控器和便携式电话的至少一个操作设备。 为了向为观众提供奖品的节目提供服务，例如，主机台用节目广播预定的控制信息。 在接收和呈现该程序的同时，接收装置通过IR信号自动发送指定程序的ID信息给周边的各操作装置。 操作设备将其电话号码附加到ID信息，并通过电话线将其发送给提供商。 提供者注册ID信息和电话号码的组合，而不注册相同的组合多次。 在特定时间，提供者从注册的组合中选择一个组合，并且以所选择的组合来电话号码以通知操作设备已经赢得了奖品。 提供商可以提供其他服务，例如使观众能够加入测验节目，或发送信息以允许查看加扰节目，而不需要执行复杂操作的观众。
