Reproduction apparatus, data processing system, reproduction method, program, and storage medium

A data processing system comprising:

• a data processing apparatus for outputting a plurality of picture data forming reproduced data to a reproduction apparatus;
• and
• a reproduction apparatus for successively and reproducing the plurality of picture data input from said data processing apparatus,
• said reproduction apparatus including,
• a reproduction memory, and
• a decoder for successively decoding said plurality of picture data in order by an order according to a designated reproduction direction, writing the decoding results in said reproduction memory, and reproducing and outputting said decoding results read from said reproduction memory, wherein
• said decoder holds the storage of said decoding results in said reproduction memory even after said decoding results stored in said reproduction memory are no longer used when continuing reproduction in said designated reproduction direction and, when receiving as input a reversal command of said reproduction direction, performs said reproduction and output using said decoding results stored in said reproduction memory before the input of said reversal command.

A reproduction method successively decoding a plurality of picture data with a reproduction apparatus, the reproduction method comprising:

• successively decoding, at the reproduction apparatus, said plurality of picture data in an order in accordance with a designated reproduction direction and writing the decoding results in a reproduction memory;
• reading, reproducing, and outputting said decoding results written in said reproduction memory;
• causing said reproduction memory to hold the storage of said decoding results even after said decoding results stored in said reproduction memory are no longer used when continuing reproduction in said designated reproduction direction;
• and
• performing reproduction and output using said decoding results already stored in said reproduction memory before input of said reversal command when receiving as input said reversal command of said reproduction direction.

A computer readable storage medium encoded with instructions, which when executed by a reproduction apparatus causes the reproduction apparatus to implement a method of successively decoding a plurality of picture data, said method comprising:

• successively decoding, at the reproduction apparatus, said plurality of picture data in an order in accordance with a designated reproduction direction and writing the decoding results in a reproduction memory;
• reading, reproducing, and outputting said decoding results written in said reproduction memory;
• causing said reproduction memory to hold the storage of said decoding results even after said decoding results stored in said reproduction memory are no longer used when continuing reproduction in said designated reproduction direction;
• and
• performing reproduction an output using said decoding results already stored in said reproduction memory before input of a reversal command for reproduction and output when receiving as input said reversal command of said reproduction direction.

A data processing apparatus comprising:

• a data processing means for outputting a plurality of picture data forming reproduced data to a reproduction apparatus;
• and
• a reproducing means for successively decoding and reproducing said plurality of picture data input from said data processing means,
• said reproducing means including,
• a reproduction memory, and
• a decoder for successively decoding said plurality of picture data in order by an order according to a designated reproduction direction, writing the decoding results in said reproduction memory, and reproducing and outputting said decoding results read from said reproduction memory, wherein
• said decoder holds the storage of said decoding results in said reproduction memory even after said decoding results stored in said reproduction memory are no longer used when continuing reproduction in said designated reproduction direction and, when receiving as input a reversal command of said reproduction direction, performs said reproduction and output using said decoding results stored in said reproduction memory before the input of said reversal command.
