    • In a digital broadcasting network, a mobile terminal receives hierarchical ESG data relating to available broadcast programs adjacent network areas. The terminal is operable whilst receiving a first program from a transmitter in a first network area for detecting a need for handover to a second network area, and for then determining from the ESG data if the same program is available in the second network area. If it is, the terminal then receives the program from a transmitter in the second network area. Otherwise, it determines one or more programs which are similar to the first program, and presents them on a display for selection by a user. This involves determining which programs have an identifier in common with the first program. The identifier can be any one or more of a program identifier, a service identifier, a channel identifier, a category identifier and a genre identifier, for example.
    • 在数字广播网络中,移动终端接收与相邻网络区域相关的可用广播节目相关的分层ESG数据。 终端可操作,同时从第一网络区域中的发射机接收第一节目,用于检测是否需要切换到第二网络区域,然后从ESG数据确定相同的节目在第二网络区域中是否可用。 如果是,则终端然后从第二网络区域中的发射机接收节目。 否则,它确定与第一程序相似的一个或多个程序,并将其呈现在显示器上以供用户选择。 这涉及确定哪些程序具有与第一程序相同的标识符。 标识符可以是例如程序标识符,服务标识符,信道标识符,类别标识符和类型标识符中的任何一个或多个。
