According to ABI Research, UltraHD/4K and mobile video are taxing the capabilities of existing codecs, network protocols and analytics. Though standards committees and industry consortia are working through a number of video standards, some pain points remain unaddressed. Areas such as the inability of TCP delivery to keep up with high throughput demands, the lack of perceptual tools in modern codecs, as well as the inefficiency of storage within CDNs all pose significant challenges, ABI says.
