Abstract
Data reproduction is performed in a mode decided on the basis of disc type information which is record data of a disc. A reading rate compatible with a physical format of a disc is compared with a reading rate compatible with a disc type, and in a case where the reading rates do not coincide with each other, data read from the disc at the physical format compatible rate is stored in the buffer, and the reproduction process is performed using the data output from the buffer at the disc type compatible rate. In a case where the physical format is BD-R or BD-RE, and the logical format is a logical format compatible with BDMV-UHD, the emulation mode reproduction accompanied with the rate conversion using the buffer is performed.
Claims12
An information processing device, comprising:
- a data processing unit that executes a reproduction process for disc record data,
- wherein the data processing unit acquires a specified physical format compatible reading rate based on a physical format of a disc and a disc type compatible reading rate associated with disc type information recorded in the disc,
- the data processing unit stores data read from the disc at a rate according to the physical format compatible reading rate in a buffer and outputs the data from the buffer at a rate according to the disc type compatible reading rate in a case where the physical format compatible reading rate does not coincide with the disc type compatible reading rate,
- the data processing unit executes a reproduction process using the data output from the buffer,
- the data processing unit executes a process of identifying a physical format and a logical format of the disc,
- the data processing unit determines whether the physical format and the logical format of the disc are a combination which is specified in advance,
- the data processing unit executes a normal reproduction process or the reproduction process in an emulation mode which is not the normal reproduction process, based on a result of the determination, and
- the data processing unit is implemented via at least one processor.
An information processing method executed in an information processing device including a data processing unit that executes a reproduction process for disc record data, comprising:
- acquiring, by the data processing unit, a specified physical format compatible reading rate based on a physical format of a disc and a disc type compatible reading rate associated with disc type information recorded in the disc;
- storing, by the data processing unit, data read from the disc at a rate according to the physical format compatible reading rate in a buffer and outputting the data from the buffer at a rate according to the disc type compatible reading rate in a case where the physical format compatible reading rate does not coincide with the disc type compatible reading rate;
- executing, by the data processing unit, a reproduction process using the data output from the buffer;
- executing, by the data processing unit, a process of identifying a physical format and a logical format of the disc;
- determining, by the data processing unit, whether the physical format and the logical format of the disc are a combination which is specified in advance;
- and
- executing, by the data processing unit, a normal reproduction process or the reproduction process in an emulation mode which is not the normal reproduction process, based on a result of the determination.
A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer causes the computer to execute a method, the method comprising:
- acquiring a specified physical format compatible reading rate based on a physical format of a disc and a disc type compatible reading rate associated with disc type information recorded in the disc;
- storing data read from the disc at a rate according to the physical format compatible reading rate in a buffer and outputting the data from the buffer at a rate according to the disc type compatible reading rate in a case where the physical format compatible reading rate does not coincide with the disc type compatible reading rate;
- executing a reproduction process using the data output from the buffer;
- executing a process of identifying a physical format and a logical format of the disc;
- determining whether the physical format and the logical format of the disc are a combination which is specified in advance;
- and
- executing a normal reproduction process or the reproduction process in an emulation mode which is not the normal reproduction process, based on a result of the determination.
