Abstract

A program data processing device includes a reading unit which reads a data part contained in program data from a file stored with program data, a feature extracting unit which extracts feature information for distinguishing between reproduction information to be reproduced from the data part and reproduction information to be reproduced from another data part, a weight acquiring unit which acquires a weight set on the extracted feature information from a weight table storage unit in which to set the weight per feature information contained in the program data and a weighting unit which allocates the acquired weight to the data part from which the feature portion is extracted.

Claims

1. A program data processing device comprising:

a reading unit to read a data part contained in program data from a file stored with program data;

a feature extracting unit to extract feature information for distinguishing between reproduction information to be reproduced from the data part and reproduction information to be reproduced from another data part;

a weight acquiring unit to acquire a weight set on the extracted feature information from a weight table storage unit in which to set the weight per feature information contained in the program data; and

a weighting unit to allocate the acquired weight to the data part from which the feature portion is extracted.

2. The program data processing device according to claim 1, further comprising a weighting reproduction unit to reproduce the program data by adjusting a reproduction speed according to the weight allocated per data part.

3. The program data processing device according to claim 1, further comprising a reproducing data weight storage unit stored with the weight in the way of being associated with the data part.

4. The program data processing device according to claim 1, wherein the data part is a data part segmented by delimitation based on a difference in viewing effect, delimitation based on a time designation, delimitation based on a frame designation or delimitation based on information specifying a program composition, and

the difference in viewing effect is detected from at least one of a change in picture, a change in sound, a sound level, existence or non-existence of character information and a change in character information.

5. The program data processing device according to claim 1, further comprising:

an operation detecting unit to detect a user'"'"'s operation when reproducing the data part, and

a weight generating unit to increment a weight on the feature information extracted from the data part when a user decreases the reproduction speed during the reproduction of the data part, decrement the weight on the feature information extracted from the data part when increasing the reproduction speed, and set the weight together with the feature information in the weight table storage unit.

6. The program data processing device according to claim 5, wherein the weight generating unit, when the reproduction of at least a portion of the data part is omitted, decrements the weight on the feature information extracted from the data part.

7. The program data processing device according to claim 1, further comprising:

a static image display unit to extract a static image from the picture contained in each reproduction unit and display the extracted static image, and

an operation unit to accept the setting of the weight on the displayed static image,

wherein the weighting unit sets the accepted weight on the data part containing the static image undergoing the acceptance of the weight setting.

8. A program data processing method by which a computer executes:
