Specifies a unified speech and audio codec which is capable of coding signals having an arbitrary mix of speech and audio content. The codec has a performance comparable to, or better than, the best known coding technology that might be tailored specifically to coding of either speech or general audio content. The codec supports single and multi-channel coding at high bitrates and provides perceptually transparent quality. At the same time, it enables very efficient coding at very low bitrates while retaining the full audio bandwidth.

Defines how uncompressed audio is carried in files in the family of standards based on the ISO base media file format. This includes mono, stereo and multi-channel audio in Linear Pulse Code Modulation (LPCM) format with various word lengths and sampling rates, and also floating point format. Such representations also occur in other container formats, such as RIFF WAV or AIFF.

Specifies the architecture of the MPEG Multimedia Middleware technology. Multimedia Middleware (M3W) allows application software to execute multimedia functions with a minimum knowledge of the inner workings of the multimedia middleware as well as to support a structured way of updating, upgrading and/or extending the multimedia middleware.

Specifies the multimedia application programming interface (API) of the MPEG Multimedia Middleware (M3W) technology. This Multimedia API provides a flexible interoperable set of media functions suitable for use in multiple products with different capabilities and in multiple application domains. ISO/IEC 23004-2:2007 specifies the following: interfaces for audio broadcast decoding, processing and rendering; interfaces for video broadcast decoding, processing and rendering; IPMP interfaces; governance interfaces. These interfaces provide a uniform view to the multimedia functionality offered by M3W platforms, but are flexible enough to allow different M3W platform vendors to distinguish themselves.

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". 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.

Specifies the interfaces of the support application programming interface (API) and the realization technology used for Fault Management in MPEG Multimedia Middleware (M3W). Fault Management is an optional framework for M3W Platforms. The goal is to have a dependable/reliable system in the context of faults. These faults can be introduced due to upgrades and extensions out of control of the device vendor. The faults can also exist because it is impossible to test all traces and configurations in the complex software systems we are building nowadays. Specifies an approach of adding fault tolerance mechanism through the use of a Middleman (wrapper), an approach for transparent instantiation of these Middlemans (wrappers), interfaces for coordination of fault handling between Middlemans (wrappers).

Specifies the interfaces of the support application programming interface (API) and the realization technology used for Integrity Management in MPEG Multimedia Middleware (M3W). Integrity Management is an optional framework for M3W Platforms. The goal is to have controlled upgrading and extension. Basically this means reducing the chance of breaking the system during an upgrade/extension and giving the ability to restore a consistent configuration when things have gone wrong. Specifies entities and interfaces for the following: Monitoring: This is basically extraction of the model that describes the software and hardware configuration of the terminal (self model), Diagnosis: Based on the self model framework, this will need to determine whether there is a fault in the configuration, Repair: The faults that have been identified during diagnosis will need to be removed when this is possible using the facilities for upgrading and extension offered by M3W.
