METHOD AND APPARATUS FOR NOTIFICATION AND INTERACTION OF MULTI-SCREEN SERVICE IN COMMUNICATION SYSTEM

A uniform multi-screen service request command template is defined by using an OMA interactive media document so that a notification of a network device about a multi-screen service and a request command of a user for multi-screen service content are compatible with the OMA standard. With the multi-screen service request command template defined in the OMA interactive media document in the invention, the user can create a request command in the uniform format simply and rapidly to thereby greatly reduce the probability of an input error of the user. Furthermore , it is not necessary to set up a connection in advance, thus greatly shortening a delay and reducing the probability of an error and hence greatly improving a quality of experience of the user.
