Abstract
Content data is classified into a data block group of high priority and an other data block group of low priority related to a user's operation. When the content data is read from a storage unit to store it in a buffer memory, a preferential data block group is firstly and selectively read to store it in the buffer memory, and then, a non-preferential data block group is read to store it in the buffer memory. In a state where free areas are present in the buffer memory, the read data blocks are stored in the free areas. When the buffer memory runs out of all free areas therein, the read data blocks are overwritten on non-preferential data blocks.
Claims8
A portable electronic device, comprising:
- a storage unit configured to store content data including a first data block group given a first priority in relation to a user's operation and a second data block group given a second priority set lower than the first priority;
- a buffer memory configured to temporarily store content data read from the storage unit;
- a reproduction unit configured to reproduce the content data read from the buffer memory;
- and
- a control unit configured to connect to the storage unit, the buffer memory and the reproduction unit, wherein
- the control unit comprises:
- a first controller configured to read the content data in block units from the storage unit to store the read data blocks in the buffer memory in accordance with their priorities;
- and
- a second controller configured to selectively read the data blocks stored in the buffer memory to make the reproduction unit reproduce the read data blocks.
A portable electronic device, comprising:
- a memory slot configured to load an external storage unit with content data including a first data block group given a first priority and a second data block group given a second priority set lower than the first priority stored therein;
- a buffer memory configured to temporarily store content data read from the buffer memory;
- and
- a reproduction unit configured to reproduce the content data read from the buffer memory;
- and
- a control unit configured to connect to the memory slot, the buffer memory and the reproduction unit, wherein
- the control unit comprises:
- a first controller configured to read the content data in block units through the memory slot from the storage unit to store the read data blocks in the buffer memory in accordance with their priorities;
- and
- a second controller configured to selectively read the data blocks stored in the buffer memory to make the reproduction unit reproduce the read data blocks.
