Abstract

A method of reproducing data from a recording medium, wherein each of the data includes reference time information indicating a reference time and packet information, includes the steps of rearranging the data on a time axis such that a time interval between adjacent data is equal to a difference between respective reference times indicated by the reference time information of the adjacent data, and outputting the rearranged data at an output rate equal to or greater than a data rate of the data. The packet information includes at least video packet information into which a compressed video signal data stream is divided, and audio packet information into which a compressed audio signal data stream is divided.

Claims (32)

1. A method of reproducing data from a recording medium, each of the data including reference time information indicating a reference time and including packet data, the method comprising:

reproducing the data from the recording medium;

obtaining a difference between respective reference times indicated by the reference time information of the reproduced adjacent data;

rearranging the data on a time axis such that a time interval between adjacent data is equal to the obtained reference time difference; and

outputting the rearranged data.

2. A method according to claim 1 , wherein the packet data includes at least video packet data into which a compressed video signal data stream is divided, and audio packet data into which a compressed audio signal data stream is divided.

3. An apparatus for reproducing data from a recording medium, the data including reference time information indicating a reference time and including packet data, the apparatus comprising:

a reproducing circuit which reproduces the data from the recording medium;

a memory which stores the data reproduced by the reproducing circuit; and

an outputting circuit which reads the data from the memory, obtains a difference between respective reference times indicated by the reference time information of the read adjacent data, rearranges the data on a time axis such that a time interval between adjacent data is equal to the obtained reference time difference, and outputs the rearranged data.

4. An apparatus according to claim 3 , wherein the packet data includes at least video packet data into which a compressed video signal data stream is divided, and audio packet data into which a compressed audio signal data stream is divided.

5. A method of outputting received data, each of the data including reference time information indicating a reference time and including packet data, the method comprising:

obtaining a difference between respective reference times indicated by the reference time information of the received adjacent data;

rearranging the data on a time axis such that a time interval between adjacent data is equal to the obtained reference time difference; and

outputting the rearranged data from an output apparatus.

6. A method according to claim 5 , wherein the packet data includes at least video packet data into which a compressed video signal data stream is divided, and audio packet data into which a compressed audio signal data stream is divided.

7. An outputting apparatus adapted to output received data reproduced from a recording medium, the data including reference time information indicating a reference time and including packet data, wherein the outputting apparatus obtains a difference between respective reference times indicated by the reference time information of the received adjacent data, rearranges the data on a time axis such that a time interval between adjacent data is equal to the obtained reference time difference and outputs the rearranged data.

8. An apparatus according to claim 7 , wherein the packet data includes at least video packet data into which a compressed video signal data stream is divided, and audio packet data into which a compressed audio signal data stream is divided.

9. A method of reproducing data from a recording medium, the data including reference time information indicating a reference time and including packet data, comprising:

reproducing the data from the recording medium;

when a difference between respective reference times indicated by the reference time information of the reproduced adjacent data is T 1 , rearranging the data on a time axis such that a time interval between adjacent data is equal to T 1 and outputting the rearranged data; and

when a difference between respective reference times indicated by the reference time information of the reproduced adjacent data is T 2 (not equal to T 1 ), rearranging the data on a time axis such that a time interval between adjacent data is equal to T 2 and outputting the rearranged data.

10. An apparatus for reproducing data from a recording medium, the data including reference time information indicating a reference time and including packet data, comprising:

a reproducing circuit which reproduces the data from the recording medium;

a memory which stores the data reproduced by the reproducing circuit; and

an outputting circuit which reads the data from the memory, when a difference between respective reference times indicated by the reference time information of the read adjacent data is T 1 , rearranges the data on a time axis such that a time interval between adjacent data is equal to T 1 , and when a difference between respective reference times indicated by the reference time information of the read adjacent data is T 2 (not equal to T 1 ), rearranges the data on a time axis such that a time interval between adjacent data is equal to T 2 and outputs the rearranged data.

11. A method of outputting received data, each of the data including reference time information indicating a reference time and including packet data, the method comprising:

when a difference between respective reference times indicated by the reference time information of the received adjacent data is T 1 , rearranging the data on a time axis such that a time interval between adjacent data is equal to T 1 and outputting the rearranged data from an output apparatus; and

when a difference between respective reference times indicated by the reference time information of the received adjacent data is T 2 (not equal to T 1 ), rearranging the data on a time axis such that a time interval between adjacent data is equal to T 2 and outputting the rearranged data from an output apparatus.

12. An outputting apparatus adapted to output received data reproduced from a recording medium, the data including reference time information indicating a reference time and including packet data, wherein:

when a difference between respective reference times indicated by the reference time information of the received adjacent data is T 1 , the outputting apparatus rearranges the data on a time axis such that a time interval between adjacent data is equal to T 1 and outputs the rearranged data; and

when a difference between respective reference times indicated by the reference time information of the received adjacent data is T 2 (not equal to T 1 ), the outputting apparatus rearranges the data on a time axis such that a time interval between adjacent data is equal to T 2 and outputs the rearranged data.
