Examples are the applied values or range of the picture size and bitrate parameters. Conformance extensions for error resilient simple scalable profile Bitstreams In addition, some test bitstreams implemented according to those guidelines are provided as an electronic annex to this document.
An example of a property is the applied arithmetic accuracy. Guidelines are given on constructing tests to verify bitstream and decoder conformance. 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 protection of bitstreams, objects and scenes.

These tests can be used for various purposes such as: Visual new levels and tools Bitstreams The characteristics of a bitstream define the subset of the standard that is exploited in the bitstream. AFX conformance extensions Bitstreams This oso is a draft of a conformance test specification for the multi-resolution frame compatible stereoscopic video coding extension of the Advanced Video Coding standard. AFX reference software extensions Software. Conformance testing Bitstreams Skip to main content.

Conformance 144964- for error resilient simple scalable profile. 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.
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. Advanced Video Coding conformance Bitstreams This document gives guidelines on how to construct bitstream test suites isoo check or verify decoder conformance. 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:. Decoder characteristics define the properties and capabilities of the applied decoding process.
