Abstract
The disclosure discloses a method for transmitting compressed rights. The method includes that: a terminal negotiates a compress algorithm with a server; the terminal requests the server through an “Extensions” field in a rights object request message to transmit the rights in compression format; the server generates a rights object response message according to a standard approach, compresses the rights in the rights object response message according to the negotiated compress algorithm, and generates a compressed rights object response message and sends the compressed rights object response message to the terminal; the terminal receives the compressed rights object response message, decompresses the rights in the received rights object response message according to the negotiated compress algorithm, and generates a decompressed rights object response message. The disclosure also discloses a system for transmitting compressed rights through which the volume of data in the Rights Object Acquisition Protocol (ROAP) communication can be reduced and the reliability of digital rights object transmission and user experience are improved.
