[0063] FIG. 1 is a diagram showing the structure of a broadcast program recording / reproducing system having a broadcast program recording / reproducing apparatus according to a first embodiment of the present invention. In FIG. 1 , a broadcast program recording / reproducing system has a terminal device 10 and a server 20 . The terminal device 10 and the server 20 communicate with each other through the Internet 40 .

[0064] Typically, the terminal device 10 is a mobile information processing terminal, such as a mobile phone, a PDA, a portable PC, and a car navigation system with a broadcast receiving function. The terminal device 10 receives a broadcast program (hereinafter, referred to as a program) transmitted from the broadcast transmission antenna 30 , records the received program, and reproduces the recorded program. When the reception level of a broadcast program decreases, the terminal device 10 instructs the server 20 to record the broadcast program instead of itself. ...

[0150] In the first embodiment, the terminal device determines whether to request the server to record the program instead based on two reception levels. Here, the terminal device may determine whether to request the server to record the program instead based on a reception level. The present embodiment is characterized in that the terminal device determines whether to request the server to substitute record the program based on a reception level.

[0151] Since the configuration of the broadcast program recording / reproducing system with the broadcast program recording / reproducing apparatus according to the second embodiment of the present invention is similar to that of the first embodiment, FIG. 1 is also used. Hereinafter, differences from the first embodiment will be mainly described.

[0152] FIG. 13 is a diagram showing a relationship between reception levels used by the reception level detection unit 105 as a judgment criterion for control. One difference from the fir...

Abstract

There is provided a broadcast program accumulation / reproduction device capable of continuously reproducing a program which is distributed / recorded in a plurality of devices. A reception level detection unit (105) detects the reception level of the received broadcast electric wave. When the reception level becomes a predetermined reception level or below, an accumulation request transmission unit (106) generates an accumulation start request packet and transmits it to a server (20). A management information write unit (107) writes management information in a terminal storage unit (104). A continuous reproduction control unit (108) judges whether a program is distributed / accumulated in storage means and an external device according to the management information. When the program is distributed / accumulated, the continuous reproduction control unit (108) acquires parts of the program from the terminal storage unit (104) and the server (20) so as to continuously reproduce them. When the program is not distributed / accumulated, the continuous reproduction control unit (108) acquires the program from the terminal storage unit (104) and reproduces it.

Description

technical field [0001] The present invention relates to a broadcast program recording / reproducing device and a broadcast program recording / reproducing method for reproducing recorded broadcast programs, and more particularly, to a broadcast program recording / reproducing device and a broadcast program recording / reproducing method, Used to reproduce broadcast programs recorded for distribution among multiple devices. Background technique [0002] In recent years, improved performance and enhanced functions of semiconductors have allowed mobile devices represented by mobile phones to capture and reproduce images. Furthermore, it is foreseeable that recording of digital broadcasts and reproduction of recorded broadcast images on mobile devices and viewing of broadcast programs on mobile devices will be realized in the future when digital terrestrial broadcasting for mobile devices starts. [0003] However, when a broadcast wave is received by a mobile device, the mobile device ...
