Abstract
A program recording device 10 compresses data of program recorded in a hard disk, at a user's desirable timing in a user's desirable compression level. A recording unit 11 records data of a program, and a re-compression scheduler 14 includes a compression setting table having a re-compression condition and an encoding method used in a compressing process. The re-compression condition and the encoding method are, in advance, established for each compressing timing. Then the scheduler 14 is activated in a predetermined interval and selects a program satisfying the re-compression condition among programs recorded by the recording unit 11. The re-compressing unit 15 compresses data of the selected program.
Claims26
A program recording device which receives a broadcast program and accumulates data of the program, comprising:
- a recording unit which records the data of the program;
- a compression setting storing unit which stores, for each compressing timing, a re-compression condition which is a condition of starting a compression of a program and an encoding method used in the compression of the program;
- a re-compression scheduler which is repeatedly activated, selects programs satisfying the re-compression condition among the recorded data of programs in the recording unit, and designates the encoding method used in the compression of the selected programs by referring to the compression setting storing unit;
- and
- a re-compressing unit which compress data of the selected programs in the encoding method designated by the re-compression scheduler.
A program recording method which receives a broadcast program and accumulates data of the program by using a computer, comprising the steps of:
- recording the data of the program;
- referring, at intervals of a predetermined period, to a re-compression condition which is a condition of starting a compression of a program and an encoding method used in the compression of the program, the re-compression condition and the encoding method being established for each compressing timing;
- selecting programs satisfying the re-compression condition among the recorded data of programs;
- designating the encoding method used in the compression of the selected programs;
- and
- compressing data of the selected programs in the encoding method designated.
A computer readable medium embodying a program of instructions executable by the computer to perform a program recording method which receives a broadcast program and accumulates data of the program, the method comprising the steps of:
- recording the data of the program;
- referring, at intervals of a predetermined period, to a re-compression condition which is a condition of starting a compression of a program and an encoding method used in the compression of the program, the re-compression condition and the encoding method being established for each compressing timing;
- selecting programs satisfying the re-compression condition among the recorded data of programs;
- designating the encoding method used in the compression of the selected programs;
- and
- compressing data of the selected programs in the encoding method designated.
A program product comprising, computer readable instructions and a computer readable medium bearing the computer readable instructions, the instructions being adaptable to enable a computer to perform a program recording method which receives a broadcast program and accumulates data of the program, the method comprising the steps of:
- recording the data of the program;
- referring, at intervals of a predetermined period, to a re-compression condition which is a condition of starting a compression of a program and an encoding method used in the compression of the program, the re-compression condition and the encoding method being established for each compressing timing;
- selecting programs satisfying the re-compression condition among the recorded data of programs;
- designating the encoding method used in the compression of the selected programs;
- and compressing data of the selected programs in the encoding method designated.
