Abstract
A reproduction apparatus that requests a distribution apparatus to distribute digital data selected by the user, comprises a prediction unit that predicts a reproducible time using remaining power of a battery and a determination unit that determines whether the digital data can be reproduced to the end or not based on the reproducible time. When it is determined that the digital data cannot be reproduced to the end, an alarm is issued indicating that the digital data cannot be reproduced to the end.
Claims15
A reproduction apparatus that requests a distribution apparatus to distribute digital data selected by a user, comprising:
- a prediction unit that predicts a reproducible time using remaining power of a battery;
- and
- a determination unit that determines whether said digital data can be reproduced to the end or not based on said reproducible time,
- wherein when it is determined that said digital data cannot be reproduced to the end, an alarm is issued indicating that said digital data cannot be reproduced to the end.
A control method for a reproduction apparatus that requests a distribution apparatus to distribute digital data selected by a user, comprising:
- predicting a reproducible time using remaining power of a battery;
- determining whether said digital data can be reproduced to the end or not based on said reproducible time;
- and
- issuing an alarm indicating that said digital data cannot be reproduced to the end when it is determined that said digital data cannot be reproduced to the end.
A distribution apparatus that distributes digital data selected by a user to a reproduction apparatus, comprising:
- a prediction unit that predicts a transmittable data size using remaining power of a battery;
- and
- a determination unit that determines whether said digital data can be distributed to the end or not based on said transmittable data size,
- wherein when it is determined that said digital data cannot be distributed to the end, an alarm is issued indicating that said digital data cannot be distributed to the end.
A control method for a distribution apparatus that distributes digital data selected by a user to a reproduction apparatus, comprising:
- predicting a transmittable data size using remaining power of a battery;
- determining whether said digital data can be distributed to the end or not based on said transmittable data size;
- and
- issuing an alarm indicating that said digital data cannot be distributed to the end when it is determined that said digital data cannot be distributed to the end.
A reception apparatus that requests a distribution apparatus to distribute digital data selected by a user, comprising:
- a prediction unit that predicts a receivable data size using remaining power of a battery;
- and
- a determination unit that determines whether said digital data can be received to the end or not based on said receivable data size,
- wherein when it is determined that said digital data cannot be received to the end, an alarm is issued indicating that said digital data cannot be received to the end.
A control method for a reception apparatus that requests a distribution apparatus to distribute digital data selected by a user, comprising:
- predicting a receivable data size using remaining power of a battery;
- deciding whether said digital data can be received to the end or not based on said receivable data size;
- and
- issuing an alarm indicating that said digital data cannot be received to the end when it is determined that said digital data cannot be received to the end.
