Video tool library
Technologies de I’m formation — Technologies vidóo MPEG — Partie 4: Bibliotheque d’outils video.
This part of ISO1IEC 23002 defines the description of the MPEG video tool library (VTL) based on the decoder description specified in ISO/IEC 23001-4. This tool library defines the specification of FUs, which are sufficient to build complete decoding solutions according to the following coding standards:
— ISOIIEC 14496-2 (MPEG-4 Simple Profile), and
— ISOIIEC 14496-10 (MPEG-4 AVC Constrained Baseline Profile).
The objective of ISO/IEC 230014 is to define the general framework principles, and this part of ISO/IEC 23002 defines the MPEG VTL that includes relevant tools (or FUs) from the existing MPEG coding standards. Each FU is defined in the form of a textual description, which can be found in 4.1. The input and output behavior follows the conventions described in Clause 5 (general-purpose FU5), Clause 6 (MPEG-4 FUs), and Clause 7 (MPEG-4 AVC FUs).
This part of ISO/IEC 23002 compliant implementations can be designed using any software or hardware language and components. The reference software for the textual specification of FUs Is written in RVC-CAL language of which a formal syntax is provided in ISO/IEC 23001-4, and which will be defined in Amendment 1 to ISO/IEC 230024.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISOIIEC 23001-4 apply.
4 FU description convention
4.1 FU interfaces
As shown in Table 1, each FU is described with the following elements:
• FU Name: Name to represent the functional unit in this specification. The name of the FU is normative and follows the naming convention described in Annex A.
• Description: Textual explanation to describe the functionality of the FU. The description must be concise. The precise normative behaviour of the algorithm (input/output, timing etc.) is specified by the the RVC-CAL reference code in Amendment 1.
• Profiles@Ievels supported: The profiles@level supported for this functional unit. It may append that a given range of values makes the FU behave for a given profile@level and another range of values makes the FU behave for another profile@level.
• Input: A token that is entering the FU through the designated input port. The token type refers to the token pool described in 4.3. The name field indicates the input port.
• Output: A token that Is coming out of the FU through the designated output port. The name’ field indicates the output pail.
• Parameter (optional): Parameters are optionally described to adjust the behavior of the FU. All the parameters must be specified with name, description and range.ISO 23002-4-2010 pdf free download.
