Abstract

A reproducing apparatus includes a reproducing section picking up any signals compressed in a plurality of different compression methods from a recording medium. The recording medium records the signals compressed in a plurality of different compression methods and record management information denoting association of the signals compressed in a plurality of different compression methods with each other, respectively. A decoding section decodes the signal picked up from said recording medium, and a recording section records reproduction management information including reproduction-interruption information in the reproducing section associated with the record management information onto the recording medium.

Claims

1. A reproducing apparatus comprising:

a receiving unit that receives a broadcast program;

a first acquiring unit that acquires first video data according to the received broadcast program;

a second acquiring unit that acquires second video data, which correspond to the first video data but is reduced as compared with the first video data;

a recording unit that records the first and second video data so that the first and second video data recorded are mutually associated with each other; and

a reproducing unit that reproduces the first video data recorded,

wherein the recording unit records reproduction management information for defining a point of interruption where the reproducing unit interrupts a reproduction of the first video data recorded, and

wherein the external reproducing device uses the reproduction management information recorded to reproduce the second video data recorded from the point of interruption.

2. A mobile device comprising:

an interface for receiving second video data and reproduction management information from a reproducing apparatus, the reproduction management information defining a point of interruption where the reproducing apparatus interrupts a reproduction of first video corresponding to the second video data, the second video data reduced as compared with the first video data;

a controller; and

a memory storing a program for configuring the controller to reproduce the second video data from the point of interruption.

3. A system for reproducing video, the system comprising a reproducing apparatus and a mobile device, wherein

the reproducing apparatus includes:

a receiving unit that receives the video;

a first acquiring unit that acquires first video data according to the received video;

a second acquiring unit that acquires second video data, which correspond to the first video data but is reduced as compared with the first video data;

a recording unit that records the first and second video data so that the first and second video data recorded are mutually associated with each other; and

a reproducing unit that reproduces the first video data recorded,

wherein the recording unit records reproduction management information for defining a point of interruption where the reproducing unit interrupts a reproduction of the first video data recorded, and the mobile device includes;

an interface for receiving the second video data and the reproduction management information from the reproducing apparatus;

a controller; and

a memory storing a program for configuring the controller to reproduce the second video data from the point of interruption.
