标准范围

ISO/IEC 23004-5:20 08规定了MPEG多媒体中间件（M3W）中用于组件下载的支持应用编程接口（API）的接口和实现技术。组件下载是M3W平台的可选框架。该实现技术的目标是实现软件组件到设备的受控下载。在这种情况下，受控意味着在实际转移组件之前，我们能够评估组件是否实际“适合”。ISO/IEC 23004-5:20 08规定了以下实体。存储库-包含可以下载的组件。目标-启用接收组件。定位器-负责定位参与特定下载的所有实体（角色的实现）。决策者-评估特定下载的可行性（这可以包括技术适合性、业务适合性等。).启动器-启动并协调下载过程。这些实体一起通过不同的部署实现了大量的组件下载和上传场景，从点对点传输到组件的广播。

ISO/IEC 23004-5:2008 specifies the interfaces of the support application programming interface (API) and the realization technology used for Component Download in MPEG Multimedia Middleware (M3W). Component Download is an optional framework for M3W Platforms. The goal of this realization technology is to enable controlled download of software components to a device. In this context controlled means that before the actual transfer of the component we are able to assess whether the component actually "fits".

ISO/IEC 23004-5:2008 specifies the following entities.

• Repository - contains components that can be downloaded.


• Target - enables receiving components.


• Locator - responsible for locating all the entities (realization of the roles) that participate in a particular download.


• Decider - assesses the feasibility of a particular download (this can include technical fit, business fit, etc.).


• Initiator - initiates and coordinates the download process.

These entities together enable through different deployments a large number of component download and upload scenarios, varying from point-to-point transfer to broadcast of components.
