Introduction
1st, 2nd, 3rd and other parts of GB/T 20090 defines the multiplex structure and encoding of audio and video information expressed, but these
Section has a lot of flexibility, can be applied to different application environments. This flexibility can be encoded bit stream various parameters
Definitions available, such as audio sampling rate, image size, frame rate, bit rate and other parameters.
As part of this first edition GB/T 20090.4, just has been released for the GB/T 20090.2, we define how to test to verify
Encoded bit stream decoder and meets the requirements specified in GB/T 20090.2-2006 test can be used for various purposes, such as.
--- Producers and users of the encoder can be used to verify whether the encoder encodes the encoded bit stream standard.
--- Decoder producers and users can use to verify GB/T 20090.2-2006 other parts required by the decoder meets the
Requirements, whether the claimed properties.
They advanced audio and video coding
Part 4. Conformance testing
1 Scope
This section GB/T 20090 gives the applications meet the test procedures and test requirements GB/T 20090.2-2006 of.

3 Terms and Definitions
GB/T 20090.2-2006 defined and the following terms and definitions apply to this document.
3.1
Compliance testing conformancetesting
For judging the encoder outputs an encoded bit stream and the decoder meets GB/T 20090.2-2006 testing.
3.2
Compliance encoded bit stream conformancecodedbitstream
Used to test whether the decoder conform GB/T 20090.2-2006 encoded bit stream, the encoded bit stream shall fully comply
GB/T 20090.2-2006 grammar rules in this section shall comply with the test bitstream of the encoded bit stream.
3.3
Reference Decoder referencedecoder
Known in line with GB/T 20090.2-2006 decoder, the decoder is used and tested for comparison. You can use the GB/T 20090.5
Reference is given as the reference software decoder.
3.4
Measured decoder measureddecoder
A decoder to pass compliance testing to determine if it meets GB/T 20090.2-2006.
3.5
Legal decoder coincidentdecoder
After the adoption of compliance testing it is determined to meet the decoder GB/T 20090.2-2006 of.
3.6
Compatible decoder compatibledecoder
After divided backward compatible decoder and forward compatible decoder backward compatible decoder means according to the old coding standard designed decoder can
In the new coding standard for all or part of the encoded bit stream is decoded; forward compatible decoder means according to the new coding standard designed solution
