Abstract: Conventionally, in a broadcast recording and reproduction apparatus that executes an application program in synchronization with service reproduction, only a single service is recorded even if the application program can be synchronized with a new service and continuously executed after a service switch. Therefore, when the service is switched during reproduction of an already-recorded service, the application program cannot perform its original operation. The present invention maintains normal operation of the application program by referring to synchronization information of the application program when the service that includes the application program is recorded, and simultaneously recording a service to which it is possible to switch.

Abstract: In the case where plural applications are executed at the same time, if each application instructs for different trick play to the same content, a difference is caused between an ideal reproduction state expected by each application and an actual reproduction state. The present invention makes it possible to keep the reproduction state unchanged as long as normal reproduction or trick play is not accepted, by including a moving picture trick play reproduction management unit which determines, in response to an instruction for one of normal reproduction and trick play, whether or not to accept, according to a rule, the instruction, and retains details specified by the instruction in the case of accepting the instruction, and a moving picture reproduction processing unit which reproduces a moving picture based on the details retained by the moving picture trick play management unit.

Abstract: Unlike the technology for a program downloaded through conventional broadcast waves, in the case of downloading a program via a network, there is a possibility that such program will be activated without noticing that the program is tampered with. For this reason, when a program is downloaded via a network, a file hierarchy for the program located on a server is constructed in a local area of a terminal. Subsequently, the authentication of the program is performed with respect to the file hierarchy constructed in the local area, and the credibility of the program is guaranteed.

Abstract: Achieved is a motion picture reproducing apparatus at low price (being little increased in price even though the number of specifications are increased) capable of receiving motion picture streams complying with various specifications such as those containing programs that operate on different pieces of middleware, and reproducing motion pictures. A middleware storage unit 43 stores a plurality of different pieces of middleware. Based on program identification information contained in a motion picture stream received by the motion picture reproducing apparatus, an applicable middleware selecting unit 40 selects middleware applicable to a program contained in the motion picture stream. A middleware reading unit 41 reads the selected applicable middleware from the middleware storage unit 43. A middleware executing unit 42 executes the read middleware.

Abstract: A method of and apparatus for checking a wrapping state of a wrapped roll having end face covers by detecting the force required to press-fit a bushing into a cylindrical core tube and comparing the detected force with a threshold value which is based on the correlation between the force required to press-fit the bushing into the cylindrical core tube and the state of tucking of the end face covers.

Abstract: An original roll positioning device sets a position of an end face of a new roll at a predetermined reference position. An end pull-out device sucks and pulls out the leading end of the new web from the positioned new roll at a predetermined length. A pair of roll-up chucks of an end roll-up device holds both sides of the leading end of the pulled-out web, and the roll-up chucks are rotated to roll up the leading end of the web at a predetermined length. A suction box sucks the web at a part between the roll up chucks and the roll, and then a cutter cuts the web along the width of the web to form a splicing part. The splicing part is sucked by the suction box, and the spliced part is made to wait in this state until the start of the splicing operation.
