Conformance testing — an element of conformity assessment, and also known as compliance testing, or type testing — is testing or other activities that determine whether a process, product, or service complies with the requirements of a specification, technical standard, contract, or regulation. Testing is often either logical testing or physical testing. The test procedures may involve other criteria from mathematical testing or chemical testing. Beyond simple conformance, other requirements for efficiency, interoperability or compliance may apply. Conformance testing is performed by an accredited independent organization, which can sometimes be the author of the standard (UL, FM for example). When testing is accompanied by Certification, the products or services may then be advertised as being certified in compliance with the referred technical standard. Manufacturers and suppliers of products and services rely on such certification including listing on the certification body's website, to assure quality to the end user and that competing suppliers are on the same level.

A signal generation board, a conformance test system and method
The application discloses a signal generation board, a consistency test system and a method. The signal generation board comprises a communication connection interface, a control processor, a signal generation device, a signal processing device and a differential signal output interface. The control processor responds to a test signal output instruction output by a digital oscilloscope through the communication connection interface, and outputs a signal generation instruction and a gain control instruction. The signal generation device generates and outputs an LFPS original signal based on the signal generation instruction. The signal processing device amplifies or reduces the amplitude of the LFPS original signal based on the gain control instruction to obtain an LFPS signal used for USB interface consistency test. The differential signal output interface is used for outputting the LFPS signal in a differential signal transmission mode. Since the signal generation board is used to replace an AFG signal generator or a bit error rate instrument in the consistency test system to generate the LFPS signal with controllable parameters, the cost of the consistency test system can be reduced, and the operation complexity of the consistency test can be reduced.

HRD parameters for layer-based conformity testing
To provide a video coding mechanism.SOLUTION: A video coding system includes encoding multiple sub-layer representations into a bitstream. Hypothetical reference decoder (HRD) parameters and a sub-layer coding picture buffer parameter present flag (sublayer_cpb_params_present_flag) are also encoded into the bitstream. When the sublayer_cpb_params_present_flag is set to 0, the HRD parameters of all sub-layer representations with a temporal identifier (TemporalId) less than the maximum TemporalId are inferred to be equal to the HRD parameters of the largest sub-layer representation with the maximum TemporalId, and a set of bitstream conformance tests is performed on the bitstream based on the HRD parameters. The bitstream is stored for communication toward a decoder.SELECTED DRAWING: Figure 8
