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

These tests can be used for various purposes such as:. Conformance extensions for error resilient simple scalable profile.
The flexibility is obtained by including parameters in the bitstream that define the characteristics of coded bitstreams. Advanced Video Coding conformance Bitstreams An example of a property is the applied arithmetic accuracy.
These tests can be used for various purposes such as: Visual new levels and tools Bitstreams Conformance extensions for error resilient simple scalable profile 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.

Conformance testing 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. AFX reference software extensions Software. Decoder characteristics define the properties and capabilities of the applied decoding process.
Guidelines are given on constructing tests to verify bitstream and decoder conformance. Skip to main content.

This document gives guidelines on how to construct bitstream test suites to check or verify decoder conformance. The characteristics of a bitstream define the subset of the standard that is exploited in the bitstream. Examples are the applied values or range of the picture size and bitrate parameters.
