Display apparatus, communication apparatus, displaying method and program recording medium

1. A displaying method comprising:

decoding a predetermined reference frame continuously after receiving the reference frame, wherein the reference frame is a frame which is received through a communication network from outside at first after channel selection; and

adjusting a timing, in which a video based on the decoded reference frame is displayed, toward shifting earlier than a time originally displaying the video based on a time information attached to the reference frame.

2. The displaying method according to claim 1 , further comprising:

adjusting a time, in which a video based on a video frame following to the reference frame in a predetermined period is displayed, earlier than a normal displaying time based on the time information attached to the video frame, and adjusting the timing so as to shorten a time difference between the time in which the video frame is displayed actually and the normal displaying time as time passes.

3. The displaying method according to claim 1 , wherein the predetermined period is a time period between the timing when the video based on the reference frame starts to display and a timing when a predetermined time passed since starting to display the video.

4. The displaying method according to claim 1 , further comprising:

adjusting a time to output a sound based on a sound frame corresponding to the reference frame so as to match the timing displaying the video based on the reference frame.

5. The displaying method according to claim 4 , further comprising:

adjusting a timing, in which a sound is output based on a sound frame following to the sound frame corresponding to the reference frame in a predetermined period, earlier than a normal outputting time based on a time information attached to the sound frame, and adjusting the timing so as to shorten a time difference between the timing in which the sound frame is output actually and the normal outputting time as time passes.

6. The displaying method according to claim 1 , further comprising:

adjusting a timing, in which a subtitle data received at first after receiving a management data managing a subtitle first after channel selection is displayed, earlier than a normal time when the subtitle data is displayed based on the management data.

7. The displaying method according to claim 6 , further comprising:

adjusting a timing, in which the subtitle data received in a predetermined period following to the subtitle data displayed at first after channel selection is displayed, earlier than a normal displaying time based on the management data, and adjusting the timing so as to shorten a time difference between a timing in which the subtitle data is displayed actually and the normal displaying time as time passes.

8. The displaying method according to claim 1 , further comprising:

decoding a predetermined non-reference frame referring to a predetermined hypothetical reference frame in a case of receiving the non-reference frame prior to the reference frame after channel selection; and

adjusting a timing, in which a video based on the decoded non-reference frame is displayed, toward shifting earlier than a normal time displaying the video based on a time information attached to the non-reference frame.

9. A non-transitory program recording medium storing a program to make a display apparatus have a function, the function achieved by performing the program comprising:

decoding a predetermined reference frame continuously after receiving the reference frame, wherein the reference frame is a frame which is received through a communication network from outside at first after channel selection; and

adjusting a time, in which a video based on the decoded reference frame is displayed, toward shifting earlier than a a time originally displaying the video based on a time information attached to the reference frame.

10. The non-transitory program recording medium according to claim 9 , the function achieved by performing the program further comprising:

adjusting a time, in which a video based on a video frame following to the reference frame in a predetermined period is displayed, earlier than a normal displaying time based on the time information attached to the video frame, and adjusting the timing so as to shorten a time difference between the timing in which the video frame is displayed actually and the normal displaying time as time passes.

11. The non-transitory program recording medium according to claim 9 , the function achieved by performing the program further comprising:

adjusting a timing to output a sound based on a sound frame corresponding to the reference frame so as to match the timing displaying the video based on the reference frame.

12. The non-transitory program recording medium according to claim 9 , the function achieved by performing the program further comprising:

adjusting a timing, in which a sound is output based on a sound frame following to the sound frame corresponding to the reference frame in a predetermined period, earlier than a normal outputting time based on a time information attached to the sound frame, and adjusting the timing so as to shorten a time difference between the timing in which the sound frame is output actually and the normal outputting time as time passes.

13. The non-transitory program recording medium according to claim 9 , the function achieved by performing the program further comprising:

adjusting a timing, in which subtitle data, received at first after receiving a management data managing a subtitle first after channel selection is displayed, earlier than a normal time when the subtitle data is displayed based on the management data.

14. The non-transitory program recording medium according to claim 13 , the function achieved by performing the program further comprising:

adjusting a timing, in which the subtitle data received in a predetermined period following to the subtitle data displayed at first after channel selection is displayed, earlier than a normal displaying time based on the management data, and adjusting the timing so as to shorten a time difference between a timing in which the subtitle data is displayed actually and the normal displaying time as time passes.

15. The non-transitory program recording medium according to claim 9 , the function achieved by performing the program further comprising:

decoding a predetermined non-reference frame referring to a predetermined hypothetical reference frame in a case of receiving the non-reference frame prior to the reference frame after channel selection; and

adjusting a timing, in which a video based on the decoded non-reference frame is displayed, toward shifting earlier than a normal time displaying the video based on a time information attached to the non-reference frame.
