Open Media Marketplace basics
1
Introduction
Purpose of this document is to collect the basic elements of the Open Media Marketplace (OMM)
project. The document is based on previous versions of the OMM documents and has benefitted
from the advances made by the MPEG Ad hoc group on Advanced IPTV Terminal in Milan on 9-10
September.

Basic OMM requirements
At a rather abstract level the OMM is an environment where Users perform actions (described by
Verbs) on Entities using Services provided by Service Providers. The OMM is enabled by the OMM
specification satisfying the following requirements.
1. OMM shall enable the provisioning of interoperable Services between OMM Users
2. OMM shall support the following Basic Services listed in chapter 5
3. OMM shall enable a Service Provider to combine several Basic Services into one Aggregated
Service
4. OMM shall enable different Providers to offer the same Basic Services and the same or partially
overlapping Aggregated Services
5. OMM shall provide the means to realise a Service Provider either as a standing entity operating
on the OMM or as an application running on a local machine, potentially with different levels of
user experience for the user
6. OMM shall facilitate the separation of technological from governance and legal concerns to
enable OMMs underpinned by different forms of governance and legal systems
7. OMM shall support commercial exploitation of content such as:
1. Advertising: based on context, user usage;
2. Payment/donation for content;
8. OMM shall enable OMMs where access to Services requires the establishment of a business
relationship between User and Service Provider
9. OMM shall enable OMMs that only require access to the Service Provider a User is subscribed
to in order to access a given type of Service in the value chain (e.g. like in OpenID where I
subscribed to one OpenID Service Provider and I am recognised by all other OpenID Service
Providers)
10. OMM shall enable secure and confidential transmission of information
11. OMM shall enable Services of different features and levels such as interactivity, local storage,
and time, space and device shifting
12. OMM shall enable Services that are independent of the delivery system such as broadcast, fixed
network, mobile network and packaged media, as well as hardware platform such as PC, mobile
phone and set top boxes, bearing in mind that
1. Some features of the standard may not be implementable on some delivery systems
and/or hardware platforms
2. Some parameters may need to be set to specific values to suit the specifics of some
delivery systems and hardware platforms for optimum performance
