Controlling modes of sub-title presentation
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.
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;
determining whether at least one end-of-block condition, of a set of two or more end-of-conditions, related to a mode of presentation of sub-titles is satisfied by the inserted sub-titles element; 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 each mode of presentation of sub-titles that is satisfied by the inserted sub-titles element.
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 at least one sub-titles block from the sub-titles stream or file, wherein the sub-titles stream or file comprises a plurality of datums that are collectively representative of an end of a block for two or more modes of presentation in the sub-titles stream or file; and
presenting on the terminal the at least one sub-titles block according to the selected mode of presentation.
8. The one or more non-transitory computer-readable storage mediums of claim 7 , wherein reading the at least one sub-titles block comprises:
reading of the sub-titles 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 sub-titles 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;
determining whether at least one end-of-block condition, of a set of two or more end-of-conditions, related to a mode of presentation of sub-titles is satisfied by the inserted sub-titles element; 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 each mode of presentation of sub-titles that is satisfied by the inserted sub-titles element.
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 at least one sub-titles block from the sub-titles stream or file, wherein the sub-titles stream or file comprises a plurality of datums that are collectively representative of an end of a block for two or more modes of presentation in the sub-titles stream or file; and
presenting on the terminal the at least one sub-titles block according to the selected mode of presentation.
19. The apparatus of claim 18 , wherein reading the at least one sub-titles block comprises:
reading of the sub-titles 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 sub-titles 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.
