AFX reference software extensions Software. In addition, some test bitstreams implemented according ido 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. These tests can be used for various purposes such as:.

The characteristics of a bitstream define the subset of the standard that is exploited in the bitstream.

An example of a property is kso 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.

This document gives guidelines on how to construct bitstream test suites to check or verify decoder conformance.

Skip to main content. Conformance extensions for error resilient simple scalable profile Bitstreams Conformance testing Bitstreams Guidelines are given on constructing tests to verify bitstream and decoder conformance. These tests can be used for various purposes such as: The flexibility is obtained by including parameters in the bitstream that define the characteristics of coded bitstreams.

Advanced Video Coding conformance Bitstreams The capabilities of a decoder specify which coded bitstreams the decoder can decode and reconstruct, by defining the subset of the standard that 144964 be exploited in decodable bitstreams.

Conformance extensions for error resilient simple scalable profile. Examples are the applied values or range of the picture size and bitrate parameters. 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 objects within objects, the association of objects within scenes, the protection of bitstreams, objects and scenes.
