Abstract

A method is provided for saving information which is provided with Audio Data but is not a part of the internal representation of this Audio Data. a. The extra information is called an Audio Descriptor (AD). b. This AD is stored away from the Audio Data, in a part of the data unit (Non-Text Object) called the Non-Text Object Signature Round Trip Area. This extra data is stored in such a way that it can be optionally used by other processes. Thus, processes which do not require this information are not penalized in any way by having to access it unnecessarily. The RFT:DCA document format, created by IBM, uses an architected arrangement of structured fields to represent AUDIO Data. This architecture is called Audio Object Content Architecture (AOCA).

Pass Through Information for AUDIO Objects and Non-Text Objects

A method is provided for saving information which is provided with Audio Data but is not a part of the internal representation of this Audio Data. a. The extra information is called an Audio Descriptor (AD).

b. This AD is stored away from the Audio Data, in a part of the

data unit (Non-Text Object) called the Non-Text

Object

Signature Round Trip Area. This extra data is stored in such a way that it can be optionally used by other processes. Thus, processes

which do not require this information are not penalized

in any way by having to access it unnecessarily. The RFT:DCA document format, created by IBM, uses an architected arrangement of structured fields to represent AUDIO Data. This architecture is called Audio Object Content Architecture (AOCA). It consists of two groups of information: 1. Audio Descriptor

-- Information on how the Audio Data was created.

2. Audio Data

-- The actual digitized Audio Data. Therefore, a conversion from RFT:DCA Audio to L3P Audio format used by the application program interface seems to require the Audio Descriptor information be lost, which is unacceptable. This AD data should be available for return to RFT:DCA, also other AUDIO users may use this AD today and even require it. In accordance with the new method, each Audio and Non-Text Object is managed within a given document as a unique data unit. This allows each Audio Object and Non-Text Object to be accessed uniq...
