OpenEPG标准定义了一种字段结构和访问方法，用于获取电子节目指南（EPG）数据，也称为元数据，用于描述音频视频内容及其使用IP相关协议的可用性。OpenEPG标准便于家庭娱乐设备访问地面、有线和卫星节目的预定事件数据；视频点播（VOD）服务和本地存储在家庭网络设备上的内容。OpenEPG允许聚合多个来源提供的元数据，如各种元数据服务提供商（MSP），包括小型和本地MSP（如教堂、学校等），以及用户提供的内容的个人元数据。

The OpenEPG standard defines a field structure and access method for obtaining electronic program guide (EPG) data, also known as metadata, for describing audio-video content and its availability using IP-related protocols. The OpenEPG standard facilitates access by home entertainment devices to scheduled event data for terrestrial, cable and satellite programming; to video on demand (VOD) services and to content stored locally on a home networked device. OpenEPG allows for aggregation of metadata provided by multiple sources such as various metadata service providers (MSPs) including small and local MSPs (such as churches, schools, etc.) and personal metadata for content provided by a user.
