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. In addition, some test bitstreams implemented according to those guidelines are provided as an electronic annex to this document.
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.

An example of a property is the applied arithmetic accuracy. AFX conformance extensions 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.
Examples are the audio sampling frequency, picture size, picture shape, picture rate, bitrate parameters, synchronisation timestamps, the association of bitstreams and synthetic objects 144964- objects, the association of objects within scenes, the protection of bitstreams, objects and scenes.
Examples are the applied values or range of the picture size and bitrate parameters. Skip to main content. Decoder characteristics define the properties and capabilities of the applied decoding process.

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: Conformance testing Bitstreams This document gives guidelines on how to construct bitstream test suites to check or verify decoder conformance. Conformance extensions for error resilient simple scalable profile Bitstreams These tests can be used for various purposes such as:. AFX reference software extensions Software.
The characteristics of a 1496-4 define the subset of the standard that is exploited in the bitstream. Advanced Video Coding conformance Bitstreams Guidelines are given on constructing tests to verify bitstream and decoder conformance.
