What is a CAVS file?
The CAVS (Chinese Audio Video Standard) file format is a digital video compression standard developed by the Audio Video Coding Standard (AVS) Working Group of China to compete with H.264/AVC and MPEG-4. Officially known as GB/T 20090, this format utilizes 8x8 integer transformation and motion compensation similar to MPEG standards but with lower computational complexity, designed specifically for High-Definition (HD) digital broadcasting and IPTV services within China. It serves as the national standard for source coding, reducing reliance on foreign intellectual property licensing fees associated with international codecs.
How to open a CAVS file
Because CAVS is a regional standard specific to the Chinese broadcast ecosystem, native playback support on Western operating systems (Windows, macOS) is nonexistent. To view these files, users require a media player capable of utilizing the libavcodec library, such as VLC Media Player or FFmpeg-based tools, which include specific decoders for AVS1-P2 and AVS+ video streams.

What is an AIFF file?
The AIFF (Audio Interchange File Format) is a lossless audio container format developed by Apple Inc., functioning as the standard uncompressed audio format for the Macintosh platform. Based on the EA IFF 85 standard, AIFF files store data in Pulse Code Modulation (PCM) format using big-endian byte ordering. It is functionally analogous to the WAV format used on Windows but differs in its header structure and byte sequence. AIFF is widely used in professional audio recording and editing due to its lack of compression artifacts and high-fidelity signal retention.
How to open an AIFF file
AIFF is the native uncompressed audio format for macOS, allowing files to be opened immediately in QuickTime, Apple Music, and Logic Pro. Windows users can open AIFF files using Windows Media Player, though some metadata may not render correctly. For professional manipulation or playback on Linux and Windows systems, VLC Media Player and Adobe Audition are the industry-standard recommendations, ensuring accurate interpretation of the big-endian PCM data streams.
