This part of ISO/IEC 23002 defines the description of the MPEG video tool library (VTL) based on the decoderdescription specified in ISO/IEC 23001-4. This tool library defines the specification of FUs, which are sufficientto build complete decoding solutions according to the following coding standards:? ISO/IEC 14496-2 (MPEG-4 Simple Profile), and? ISO/IEC 14496-10 (MPEG-4 AVC Constrained Baseline Profile).The objective of ISO/IEC 23001-4 is to define the general framework principles, and this part ofISO/IEC 23002 defines the MPEG VTL that includes relevant tools (or FUs) from the existing MPEG codingstandards. Each FU is defined in the form of a textual description, which can be found in 4.1. The input andoutput behavior follows the conventions described in Clause 5 (general-purpose FUs), Clause 6 (MPEG-4FUs), and Clause 7 (MPEG-4 AVC FUs).This part of ISO/IEC 23002 compliant implementations can be designed using any software or hardwarelanguage and components. The reference software for the textual specification of FUs is written in RVC-CALlanguage of which a formal syntax is provided in ISO/IEC 23001-4, and which will be defined in Amendment 1to ISO/IEC 23002-4.
