As the demand for multimedia services grows, media content must be processed before being transmitted via a content delivery network (CDN). Artificial intelligence (AI) is a core technology for improving the efficiency and intelligence of media processing services (MPS), including adaptive transcoding, etc. This Recommendation specifies the technical requirements and architecture for AI-based MPS (AI-MPS), clarifying that MPS relies on cloud computing technology to process audio and video in a cost-effective, user-friendly, elastic, flexible and highly scalable manner, providing standard support for AI-powered multimedia services.
