Internet Protocol television (IPTV) is the delivery of television content over internet protocol networks. BS IEC 62766 series discusses consumer terminal function for access to IPTV and open internet multimedia services. The OPEN IPTV FORUM specifies the user-to-network interface (UNI) for consumer terminals to access IPTV and open internet multimedia services over managed or non-managed networks.
BS IEC 62766-5-1 specifies the Declarative Application Environment (DAE) component of the Open IPTV Forum terminal function. The DAE is a declarative language based environment (browser) based on the Open IPTV Forum web standards TV profile specified in BS IEC 62766-5-2 for the presentation of user interfaces and including scripting support for interaction with network server-side applications and access to the APIs of the other OITF functions.
BS IEC 62766-5-1 specifies the initiation of HTTP adaptive streaming from the DAE. BS IEC 62766-5-1 provides an overview of the Open IPTV Forum terminal function architecture of DAE.
BS IEC 62766-5-1 on IPTV DAE is useful for:
An IPTV system is used to provide video content over a private network in an enterprise. The DAE provides to service providers and content providers the capabilities of the terminal device to allow access to IPTV services.
BS IEC 62766-5-1 covers the concept of a DAE application, in which files and assets are considered to be part of a DAE application, and how this relates to DAE application security and lifecycle. BS IEC 62766-5-1 describes how DAE applications discover the information of the gateway and subsequently interact with the gateway.
BS IEC 62766-5-1 describes how resources (including non-granular resources such as memory and display area) are shared between multiple applications that may be running simultaneously. Applications should be able to tolerate the loss of scarce resources if they are needed by another application and should follow current industry best practices in order to minimize the resources they consume.
BS IEC 62766-5-1 helps you to provide a high-quality entertainment experience to your customers.
