Abstract

Creating a sub-titles stream or file composed of sub-titles elements. For each sub-titles element in said sub-titles elements, a sub-titles element is inserted into the sub-titles stream or file, at least one end-of-block condition related to a mode of presentation of sub-titles is verified, and a datum representative of an end of a block according to the mode of presentation of sub-titles is inserted into the sub-titles stream or file upon satisfying said at least one end-of-block condition. A sub-titles stream or file may be presented on a terminal of a user by selecting on the terminal a mode of presentation of sub-titles, reading a sub-titles block associated with the mode of presentation in the stream or file, and presenting on the terminal the at least one sub-titles block according to the mode of presentation.

First claim

What is claimed is:

1 . One or more non-transitory computer-readable storage mediums storing one or more sequences of instructions for creating a sub-titles stream or file composed of sub-titles elements, wherein execution of the one or more sequences of instructions by one or more processors causes:
for each sub-titles element in said sub-titles elements, performing:
inserting a sub-titles element into the sub-titles stream or file;
verifying at least one end-of-block condition related to a mode of presentation of sub-titles; and
upon satisfying said at least one end-of-block condition, inserting into the sub-titles stream or file a datum representative of an end of a block according to the mode of presentation of sub-titles.

2 . The one or more non-transitory computer-readable storage mediums of claim 1 , wherein said at least one end-of-block condition comprises a detection of at least one predefined character marking an end of the block.

3 . The one or more non-transitory computer-readable storage mediums of claim 2 , wherein said at least one predefined character corresponds to or comprises a full stop, a comma, a semi-colon, or a punctuation character.

4 . The one or more non-transitory computer-readable storage mediums of claim 1 , wherein the sub-titles stream complies with the MPEG-TS standard.

5 . The one or more non-transitory computer-readable storage mediums of claim 1 , wherein the file complies with at least one standard based on W3C TTML.

6 . The one or more non-transitory computer-readable storage mediums of claim 5 , wherein a datum representative of the end of a block is written in a specific tag.

7 . One or more non-transitory computer-readable storage mediums storing one or more sequences of instructions for presenting a sub-titles stream or file on the terminal of a user, wherein execution of the one or more sequences of instructions by one or more processors causes:
selecting on the terminal a mode of presentation of sub-titles; reading a sub-titles block associated with the mode of presentation in the stream or file; and presenting on the terminal the at least one sub-titles block according to the mode of presentation.

8 . The one or more non-transitory computer-readable storage mediums of claim 7 , wherein reading the sub-titles block comprises:
reading of the stream or file up to a datum representative of the end of a sub-titles block according to the selected mode of presentation of sub-titles.

9 . The one or more non-transitory computer-readable storage mediums of claim 7 , wherein the stream complies with the MPEG-TS standard.

10 . The one or more non-transitory computer-readable storage mediums of claim 7 , wherein the file complies with at least one standard based on W3C TTML.

11 . The one or more non-transitory computer-readable storage mediums of claim 10 , wherein a datum representative of the end of a block is written in a specific tag.

12 . An apparatus for creating a sub-titles stream or file composed of sub-titles elements, comprising:
one or more processors; and one or more non-transitory computer-readable storage mediums storing one or more sequences of instructions, which when executed, cause:
for each sub-titles element in said sub-titles elements, performing:
inserting a sub-titles element into the sub-titles stream or file;
verifying at least one end-of-block condition related to a mode of presentation of sub-titles; and
upon satisfying said at least one end-of-block condition, inserting into the sub-titles stream or file a datum representative of an end of a block according to the mode of presentation of sub-titles.

13 . The apparatus of claim 12 , wherein said at least one end-of-block condition comprises a detection of at least one predefined character marking an end of the block.

14 . The apparatus of claim 13 , wherein said at least one predefined character corresponds to or comprises a full stop, a comma, a semi-colon, or a punctuation character.

15 . The apparatus of claim 12 , wherein the sub-titles stream complies with the MPEG-TS standard.

16 . The apparatus of claim 12 , wherein the file complies with at least one standard based on W3C TTML.

17 . The apparatus of claim 16 , wherein a datum representative of the end of a block is written in a specific tag.

18 . An apparatus for presenting a sub-titles stream or file on the terminal of a user, comprising:
one or more processors; and one or more non-transitory computer-readable storage mediums storing one or more sequences of instructions, which when executed, cause:
selecting on the terminal a mode of presentation of sub-titles;
reading a sub-titles block associated with the mode of presentation in the stream or file; and
presenting on the terminal the at least one sub-titles block according to the mode of presentation.

19 . The apparatus of claim 18 , wherein reading the sub-titles block comprises:
reading of the stream or file up to a datum representative of the end of a sub-titles block according to the selected mode of presentation of sub-titles.

20 . The apparatus of claim 18 , wherein the stream complies with the MPEG-TS standard.

21 . The apparatus of claim 18 , wherein the file complies with at least one standard based on W3C TTML.

22 . The apparatus of claim 21 , wherein a datum representative of the end of a block is written in a specific tag.
