Abstract
As stated in the previous chapter, the concept of CRID is an element of prime importance in the TV-Anytime universe we are describing. In order to implement services with a high added value such as those presented in Chap. 1, it is vital to be able to reference contents unambiguously, regardless of their location, that is, without knowing specific broadcast information (time, date and channel) or how to obtain them through a network, for instance, by means of a streaming service or by downloading a file from an Internet server.
