As more Pay TV content is delivered as streaming video to the television, so the requirements for improved audio become more obvious. If operators want consumers to move seamlessly between their broadcast and IP services within their UI environment, like when they are watching VOD on hybrid STBs, they need to avoid a sudden loss of quality from, for example, 5.1 Surround Sound to simple stereo.
Raising the streaming Quality of Experience (QoE) to match that of broadcast delivery encompasses many challenges. We need subtitling and audio description to become the norm, and trick-play functions to match a local PVR for content delivered from the cloud. There are high hopes that improved compression and CDN technologies will deliver broadcast-standard picture quality and reliability at some point.
