Brief Patent Description - Full Patent Description - Patent Application Claims
[0001] This application is a division of U.S. patent application Ser. No. 09/913,360 filed on Oct. 9, 2001. TECHNICAL FIELD [0002] The present invention relates to a transmitter and a receiver and, more particularly, to a transmitter which transmits a program and attribute information of the program and a receiver which receives the program and accumulates part or whole of the program. BACKGROUND ART [0003] Transmission and reception systems are known which comprise a transmitter for transmitting program and attribute information of the program and a receiver for receiving the program and attribute information transmitted by the transmitter and for accumulating part of or whole of the program. [0004] In the transmission and reception system, the attribute information of a program transmitted by the transmitter is information indicating the type of information provided by the transmitter to users. [0005] A high level of secrecy is required for attribute information indicating the type of information provided by the transmitter to users because a broadcast can be received by anybody. [0006] For this reason, when attribute information for which secrecy is a must is to be transmitted to each receiver, the transmitter transmits attribute information which has been coded according to a predetermined coding system to the receiver. [0007] Only receivers having a key to decode the codes can decode the coded attribute information transmitted by the transmitter. [0008] However, there is no guarantee that a coding system will be permanently safe after it is once decided because of recent advances of decoding techniques. A reduction of the safety of a coding system necessitates replacement of IC cards of all receivers. [0009] When a plurality of receivers employ different coding systems, the size of a decoding program in the receivers increases; processes in the program become complicated; and the hardware configuration of the receiver also becomes complicated. [0010] It is an object of the invention to provide a transmitter and a receiver capable of transmitting and receiving attribute information of a program while maintaining a high level of secrecy in a simple hardware configuration without using a coding system. DISCLOSURE OF THE INVENTION [0011] A transmitter according to the invention is a transmitter in a transmission and reception system comprising a transmitter for transmitting a program and attribute information of the program and a receiver for receiving the program and accumulating part or whole of the program, the transmitter transmitting meaning information indicating the meaning and contents of the attribute information in addition to the program and the attribute information to achieve the above-described object. [0012] A program for executing the function of accumulating part or whole of the program may be further transmitted. [0013] Further, the time of distribution of the program may be transmitted. [0014] A receiver according to the invention has a receiving section for receiving a program, attribute information, and meaning information, a user attribute storing section for storing user attributes that are the attributes of a viewer, and accumulation control section for accumulating part or whole of the program according to the attribute information that is interpreted based on the meaning information and the user attributes, whereby the above-described object is achieved. [0015] A separating section for separating the program received by the receiving section, the attribute information, and meaning information may be further provided. [0016] An accumulation control function receiving section for receiving a program for executing the function of accumulating part or whole of the program may be further provided, and the accumulation control section may operate based on the program received by the accumulation control function receiving section. [0017] The means of the accumulation control function receiving section for receiving the program may be means for receiving a broadcast, and there may be further provided a determining section for determining whether the accumulation control function receiving section has failed to receive the program from said broadcast or not and an accumulation control function acquiring section for acquiring the program through a network when the determining section determines that the reception has failed. [0018] A distribution time receiving section for receiving the time of distribution of the program may be further provided, and the receiving operation of the accumulation control function receiving section may be performed at a point in time associated with the time of distribution. [0019] A method of transmission according to the invention is a method of transmission in a transmission and reception system comprising a transmitter for transmitting a program and attribute information of the program and a receiver for receiving the program and accumulating part or whole of the program, the method including a step of transmitting the program, a step of transmitting the attribute information, and a step of transmitting meaning information indicating the meaning and contents of the attribute information to achieve the above-described object. [0020] It may further include a step of transmitting a program for executing the function of accumulating part or whole of the program. [0021] It may further include a step of transmitting the time of distribution of the program. Continue reading about Transmitter and receiver...
