Visual new levels and tools Bitstreams In addition, some test bitstreams implemented according to those guidelines are provided as an electronic annex to this document. The characteristics of a bitstream define the subset of the standard that is exploited in the bitstream.

This document gives guidelines on how to construct bitstream test suites to check or verify decoder conformance. These tests can be used for various purposes such as:.

Guidelines are given on constructing tests to verify bitstream and decoder conformance. Advanced Video Coding conformance Bitstreams AFX conformance extensions Bitstreams Examples are the audio sampling frequency, picture size, picture shape, picture rate, bitrate parameters, synchronisation timestamps, the association of bitstreams and synthetic objects within objects, the association of objects within scenes, the iao of bitstreams, objects and scenes.

An example of a property is the applied arithmetic accuracy. The flexibility is obtained by including parameters in the bitstream that define the characteristics of coded bitstreams.

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

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. Conformance extensions for error resilient simple scalable profile.

Conformance extensions for error resilient simple scalable profile Bitstreams Conformance testing Bitstreams The capabilities of a decoder specify which coded bitstreams uso decoder can decode and reconstruct, by defining the subset of the standard that may be exploited in decodable bitstreams. AFX reference software extensions Software.

Decoder characteristics define the properties and capabilities of the applied decoding process. 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.
