用于数字电视的基于虚拟通道的统一接口实现方法
摘要：
本发明涉及一种用于数字电视的基于虚拟通道的统一接口实现方法，包括以下步骤：实际通道向一虚拟通道接口注册通道快照，该通道快照是指向或者标志该实际通道的唯一标识；在虚拟通道接口中保存经注册的实际通道的通道快照；以及当虚拟通道接口收到数据或文件访问请求时，利用通道快照激活包含待访问数据或文件的实际通道，使得可以通过该虚拟通道接口调用该实际通道而访问数据或文件。由此，应用程序不要了解存储文件或获取数据的通道具体细节，只需要调用由本接口系统提供的接口方法即可完成应用的开发。
摘要（英）：

The invention relates to a realization method of a unified interface based on a virtual channel for a digital TV, which comprises the following steps: an actual channel registers a channel snapshot to a virtual channel interface, and the channel snapshot is the only mark pointing to or marking the actual channel; the registered channel snapshot of the actual channel is stored in the virtual channel interface; and when the virtual channel interface receives a data or file visit request, the actual channel containing data or a file to be visited is activated by utilizing the channel snapshot, thereby calling the actual channel through the virtual channel interface so as to visit the data or the file. Therefore, an application program does not need to know concrete details of a channel of storing the file or obtaining the data, and development of an application can be finished only needing to call the interface method provided by the interface system.
