Conformance testing Bitstreams AFX reference software extensions Software.

The capabilities of a decoder specify which coded bitstreams the decoder can decode and reconstruct, by defining the subset 144964- 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. Guidelines are given on constructing tests to verify bitstream and decoder conformance.

The characteristics of a bitstream define the subset of the standard that is exploited in the bitstream. In addition, some test bitstreams implemented according to those guidelines are provided as an electronic annex to this document. Visual new levels and tools Bitstreams This document gives guidelines on how to construct bitstream test suites to check or verify decoder conformance.

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

Skip to main content. 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. Conformance extensions for error resilient simple scalable profile Bitstreams Examples are the applied values or range of the picture size and bitrate parameters. The flexibility is obtained by including parameters in the bitstream that define the characteristics of coded bitstreams.

An example of a property is the applied arithmetic accuracy.

Conformance testing | MPEG

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 lso purposes such as: AFX conformance extensions Bitstreams These tests can be used for various purposes such as:.
