Virtual reality (VR) has gained a lot of attention due to market availability of consumer devices. A challenge for wider use is the ability to stream VR content to the user. This paper looks at aspects of 360° video streaming and the considerations for possible solutions. The primary focus lies on current efforts to develop standards for interoperable 360° video streaming. These standards include the Moving Picture Experts Group's (MPEG) work on omnidirectional media format (OMAF) and the integration in MPEG dynamic adaptive streaming over HTTP, which is considered a cornerstone of 360° video streaming services with OMAF content. This paper also discusses content protection approaches and considerations.
