N, Text of ISO/IEC /PDAM46 Conformance Testing for Internet Video Coding | MPEG
AFX reference software extensions Software. This document gives guidelines on how to construct bitstream test suites to check or verify decoder conformance.
The flexibility is obtained by including parameters in the bitstream that define the characteristics of coded bitstreams.
Conformance extensions for error resilient simple scalable profile.
Conformance extensions for error resilient simple scalable profile Bitstreams AFX conformance extensions Bitstreams Guidelines are given on constructing tests to verify bitstream and decoder conformance. This document kso a draft of a conformance test specification for the multi-resolution frame compatible stereoscopic video coding extension of the Advanced Video Coding standard.
Decoder characteristics define the properties and capabilities of the applied decoding process. A bitstream can be decoded by a decoder if the characteristics of the coded bitstream are 14496-4 the subset of the standard specified by the decoder capabilities.
The characteristics of a bitstream define the subset of the standard that is exploited in the bitstream.
Conformance testing Bitstreams These tests can be used for various purposes such as:. These tests can be used for various purposes such as: Advanced Video Coding conformance Bitstreams 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.
Examples are the applied values or range of the picture size and bitrate parameters. An example of a property is the applied arithmetic accuracy. In addition, some test bitstreams implemented according to those guidelines are provided as an electronic annex to this document. Skip to main content. 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.
