scope:

NEN-IEC 62766-5-2 specifies a profile of HTML5, CSS and other related web technologies for connected TVs. Its goal is to describe a common profile that can be relied on by content and service providers and implemented by manufacturers. It does not describe extensions or modification to any of the referenced technologies but only tries to define a subset of web standards that are suitable and useful for TV deployments and at the same time stable enough to provide a good degree of confidence that real interoperability can be achieved. It may add clarifications and/or additional constraints where these are needed due to the nature of the target deployment environment. This part of IEC 62766 only describes a minimum subset of web technology that a terminal compliant with this profile is required to support. This does not preclude terminals to support more technologies than the ones described in this profile.
