There are varieties of data formats available for image, audio and full motion video objects. Since the varieties are so large, controlling them becomes difficult. So we should standardize on a single format. Instead, we should select a set for which reliable conversion application tools are available.
- Another key design issue is to standardize on one or two compression formula for each type of data object. For example for facsimile machines, CCITT group 3 and 4 should be included in the selected standard. Similarly for full motion video, the selected standard should include MPEG and its derivatives such as MPEG 2.
- Standardizing protocols in WAN's is essential to ensure that multimedia objects can be transformed from one LAN via a WAN to another LAN without loss of information. All hubs, routers, switches, etc.must be standardized.
- Storing and retrieving of very large objects is an important consideration. Storing should be done quickly and retrieving should be done efficiently.
- While doing storage, it is useful to have some information about the object itself available outside the object to allow a user to decide if they need to access the object data.
