What are the best ways to compress and transmit 4K and 8K videos over IP networks?

1 Codec selection

A codec is a software or hardware tool that encodes and decodes video data, using various algorithms and parameters. Choosing the right codec for your 4K or 8K video can make a big difference in the compression ratio, quality, and compatibility of your video. Some of the most popular codecs for 4K and 8K videos are HEVC (High Efficiency Video Coding), AV1 (AOMedia Video 1), and VVC (Versatile Video Coding). These codecs use advanced techniques such as adaptive block partitioning, motion compensation, intra prediction, and entropy coding to achieve high compression efficiency and quality. However, they also require more processing power and may not be supported by all devices and platforms.

2 Format selection

A format is a container that holds the video data and metadata, such as audio, subtitles, and chapters. Choosing the right format for your 4K or 8K video can affect the compatibility, functionality, and performance of your video. Some of the most common formats for 4K and 8K videos are MP4 (MPEG-4 Part 14), MKV (Matroska), and WebM. These formats support various codecs, such as HEVC, AV1, and VVC, and offer features such as streaming, subtitles, and chapters. However, they also have different advantages and disadvantages, such as file size, compatibility, and licensing.

3 Protocol selection

A protocol is a set of rules and procedures that govern the communication and transmission of data over a network. Choosing the right protocol for your 4K or 8K video can influence the speed, reliability, and security of your video. Some of the most widely used protocols for 4K and 8K videos are HTTP (Hypertext Transfer Protocol), RTMP (Real-Time Messaging Protocol), and SRT (Secure Reliable Transport). These protocols enable different modes of transmission, such as progressive download, adaptive streaming, and live streaming. However, they also have different trade-offs, such as latency, bandwidth, and encryption.

4 Technique selection

A technique is a method or strategy that enhances or optimizes the compression and transmission of video data over a network. Choosing the right technique for your 4K or 8K video can improve the quality, efficiency, and experience of your video. Some of the most effective techniques for 4K and 8K videos are transcoding, transrating, transsizing, and transcrypting. These techniques involve changing or adapting the video data to different formats, resolutions, bitrates, or encryption levels, depending on the network conditions, device capabilities, or user preferences. However, they also have different costs, benefits, and challenges, such as processing time, quality loss, and complexity.
