Abstract: Methods, apparatuses, and systems for updating a User Interface (UI) in a Remote UI (RUI) client are described. Upon detecting a change in its capability, the RUI client stores a UI state of a UI page and requests a RUI server to update the UI page according to the changed capability. The RUI client receives a UI page updated according to the changed capability from the RUI server, where the stored UI state is reflected in the updated UI page, and the RUI client renders the UI state-reflected updated UI page.

Abstract: A method for providing a broadcast service is provided. The method includes transmitting a user datagram protocol (UDP)/internet protocol (IP) packet including a first message, the first message containing information about a message to be signed and transmitted, and transmitting a moving picture experts group (MPEG) media transport protocol (MMTP) packet including a second message, the second message containing information about the broadcast service and information indicating whether the information about the broadcast service is signed. The first message includes an identifier of a key used to verify a signature of the message to be transmitted and signed and an identifier of a hash algorithm used to calculate a hash value of the message to be transmitted and signed.
