[0080] Hereinafter, an apparatus and method according to a first embodiment of the present invention will be described with reference to the accompanying drawings. The present invention aims at recording and reproducing content transmitted and received in an arbitrary medium; however, in this embodiment, a cable TV broadcasting system is described as an example. In this cable TV broadcasting system, a broadcast recording and reproducing device (recording and reproducing device) is generally called a terminal device.

[0081] 1 is a block diagram showing the relationship of devices constituting a broadcasting system; the broadcasting system is composed of a broadcasting station end system 101 (head end) and three terminal devices, terminal device A111, terminal device B112 and terminal device C113. The coupling 121 between the broadcast station end system and each terminal device in the cable system is a wired coupling such as a coaxial cable, an optical fiber cable, or the lik...

[0226] Hereinafter, an apparatus and method according to a second embodiment of the present invention will be described with reference to the accompanying drawings.

[0227] Since the hardware structure and the like used in the second embodiment are the same as those in the first embodiment of the present invention, FIGS. 1 to 16 are used here again. Since the functions of the constituent elements in these illustrations are the same as those of the first embodiment with the same names and the same reference numbers, the description thereof will not be repeated.

[0228] The software structure of the second embodiment is the same as that shown in FIG. 17 . Since the functions of the constituent units other than the AM 1704b and the trick-play manager 1704g are the same as those of the same name and the same reference number in the software structure of the first embodiment, description will not be repeated. Since various data formats used in the second embodiment are the same ...

[0254] Hereinafter, an apparatus and method according to a third embodiment of the present invention will be described with reference to the accompanying drawings.

[0255] Since the hardware configuration and the like used in the third embodiment are the same as those in the first embodiment of the present invention, FIGS. 1 to 16 are used here again. Since the functions of the constituent elements in these illustrations are the same as those of the first embodiment with the same names and the same reference numbers, the description thereof will not be repeated.

[0256] The software structure of the third embodiment is the same as that shown in FIG. 17 . Since the functions of constituent units other than AM 1704b, trick play manager 1704g, and graphics 1704i are the same as those of the same name and same reference number in the software structure of the first embodiment, description will not be repeated. Since the various data formats used in the third embodiment are the ...

Abstract

A recording and reproduction apparatus shifts a program which is currently being executed to a paused state, or temporarily shifts a mode of graphics drawing by an application program to an invisible mode, in order to reproduce a recorded video with trick play functionality at a reproduction speed different from a normal reproduction speed, thereby making it possible to prevent an unexpected behavior of the program even when an application program is executing a time-consuming process.

Description

technical field [0001] The present invention relates to a recording and reproducing apparatus that accumulates content and reproduces the accumulated content. In particular, the present invention relates to: an arrangement for receiving broadcast waves including content composed of video, audio and data such as programs, and for accumulating video, audio and data synchronized with each other with data is multiplexed into a broadcast wave and transmitted; and a method for performing trick play such as fast forward and rewind on content while maintaining synchronization between video, audio and data such as programs setting. Background technique [0002] Various contents are included in broadcast waves transmitted from broadcast stations. In addition to video and audio used in general television programs, there are cases where data is included in the content. There are several methods of transmitting data, which can be roughly classified into a method of transmitting data c...
