1, The full form of AVS is Address Verification Service

The Address Verification Service (AVS) is a tool provided by credit card processors and issuing banks to merchants in order to detect suspicious credit card transactions and prevent credit card fraud. The AVS checks the billing address submitted by the card user with the cardholder’s billing address on record at the issuing bank. This is done as part of the merchant’s request for authorization of the credit card transaction. The credit card processor sends a response code back to the merchant indicating the degree of address matching, thereby authenticating ownership of a credit or debit card in a non-face-to-face transaction. This process helps the merchant in determining whether a card transaction should be accepted or rejected.

AVS is one of the most common tools used by merchants to prevent credit card fraud. However, it is not a foolproof system, since the billing address provided by a bona fide customer may not always match the address on record at the card issuer. Reasons for such a mismatch would be a recent move by the cardholder or an address of record that was incorrect to begin with. In such cases, the merchant runs the risk of rejecting a perfectly legitimate transaction. AVS is an important part of the credit card authentication process and applies to cardholder addresses from the United States, Canada, and the United Kingdom.

2, The full form of AVS is Audio Video Coding Standard

Audio Video Coding Standard (AVS) refers to the digital audio and digital video series compression standard formulated by Audio and Video coding standard workgroup of China according to the open international rules. Formulation of 3-generation AVS standards has been completed. 

The first generation AVS standard includes “Information Technology, Advanced Audio Video Coding, Part 2: Video” (AVS1 for short) and “Information Technology, Advanced Audio Video Coding Part 16: Radio Television Video” (AVS+ for short).

For the second generation AVS standard, referred to as AVS2, the primary application target is Ultra HD (high definition) video, supporting the efficient compression of ultra-high-resolution (4K above), HDR (high dynamic range) videos, and it has been submitted to the IEEE international standard (Standard No.: IEEE1857.4) for application.

The “AVS patent pool” provides authorization for the AVS standard, which charges only a small amount of royalties for terminal products (like TVs), excluding content providers and operators. The royalty for the first generation AVS standard is one yuan per terminal.

In order to propel the development and promotion of the AVS standard, Huawei, TCL, Skyworth and other companies established Zhongguancun audiovisual industry technology innovation alliance (abbreviation: AVS industry alliance), which is devoted to the development and promotion of the AVS standard
