These tests can be used for various purposes such as: Visual new levels and tools Bitstreams Examples are the audio sampling frequency, picture size, picture shape, picture rate, bitrate parameters, synchronisation timestamps, the association of bitstreams and synthetic is within objects, the association of objects within scenes, the protection of bitstreams, objects and scenes.

Decoder characteristics define the properties and capabilities of the applied decoding process. Advanced Video Coding conformance Bitstreams ido Conformance extensions for error resilient simple scalable profile Bitstreams This document gives guidelines on how to construct bitstream test suites to check or verify decoder conformance.

The flexibility is obtained by including parameters in isk bitstream that define the characteristics of coded bitstreams. An example of a property is the applied arithmetic accuracy. The capabilities of a decoder specify which coded bitstreams the decoder can decode and reconstruct, by defining the subset of the standard that may be exploited in decodable bitstreams.

The characteristics of a bitstream define the subset of the standard that is exploited in the bitstream. AFX conformance extensions Bitstreams Conformance testing Bitstreams AFX reference software extensions Software.

Examples are the applied values or range of the picture size and bitrate parameters. These tests can be used for various purposes such as:.

Lso are given on constructing tests to verify bitstream and decoder conformance. A bitstream can be decoded by a decoder if the characteristics of the coded bitstream are within the subset of the standard specified by the decoder capabilities. This document is a draft of a conformance test specification for the multi-resolution frame compatible stereoscopic video coding extension of the Advanced Video Coding standard.
