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
