Abstract

Various embodiments are generally directed an apparatus and method for determining a size of a subtitle area in a subtitle image comprising subtitle information, creating a new subtitle image comprising the subtitle information, the new subtitle image having a same size as the size of the subtitle area and is smaller than the subtitle image and combining the new subtitle image with a video image for presenting the subtitle information.

First claim

1 .- 22 . (canceled)

23 . An apparatus, comprising:
processing circuitry; a subtitle size determination component for execution on the processing circuitry to determine a size of a subtitle area in a subtitle image comprising subtitle information; a subtitle creation component for execution on the processing circuitry to create a new subtitle image comprising the subtitle information, the new subtitle image having a same size as the size of the subtitle area and is smaller than the subtitle image; and a subtitle composition component for execution on the processing circuitry to combine the new subtitle image with a video image for presenting the subtitle information.

24 . The apparatus of claim 23 , the subtitle image comprising a plurality of lines of pixels, and the subtitle size determination component to:
process the plurality of lines in a top-to-bottom order or a bottom-to-top order; determine a minimum line value and a maximum line value in the subtitle image having subtitle information; and determine a number of lines between the minimum line value and the maximum line value to determine the size of the subtitle area.

25 . The apparatus of claim 24 , the subtitle size determination component to set the minimum line value to a lowest numbered line having subtitle information when processing the plurality of lines and to set the maximum line value to a highest numbered line having subtitle information when processing the plurality of lines.

26 . The apparatus of claim 24 , the subtitle size determination component to set the minimum line value and the maximum line value to a default value prior to processing the plurality of lines.

27 . The apparatus of claim 24 , the subtitle size determination component to determine whether a particular line of the plurality lines has subtitle information based on a summation of pixel values for the pixels in the particular line.

28 . The apparatus of claim 24 , the subtitle size determination component to determine whether the subtitle information is in a top portion or a bottom portion of the subtitle image, and process the plurality of lines in the top-to-bottom order when the subtitle information is in the top portion of the subtitle image and in the bottom-to-top order when the subtitle information is in the bottom portion of the subtitle image.

29 . The apparatus of claim 28 , the subtitle composition component to combine the new subtitle image comprising combining the new-subtitle image in a top portion or bottom portion of the video image based on whether the subtitle information is in the top portion of the subtitle image or the bottom portion of the subtitle image.

30 . The apparatus of claim 23 , comprising:
a memory coupled with the processing circuitry; a transceiver coupled with the processing circuitry; and a display device coupled with the processing circuitry.

31 . A computer-implemented method, comprising:
determining a size of a subtitle area in a subtitle image comprising subtitle information; creating a new subtitle image comprising the subtitle information, the new subtitle image having a same size as the size of the subtitle area and is smaller than the subtitle image; and combining the new subtitle image with a video image for presenting the subtitle information.

32 . The computer-implemented method of claim 31 , the subtitle image comprising a plurality of lines of pixels, and the method comprising:
processing the plurality of lines in a top-to-bottom order or a bottom-to-top order; determining a minimum line value and a maximum line value in the subtitle image having subtitle information; and determining a number of lines between the minimum line value and the maximum line value to determine the size of the subtitle area.

33 . The computer-implemented method of claim 32 , comprising:
setting the minimum line value and the maximum line value to a default value; setting the minimum line value to a lowest numbered line having subtitle information when processing the plurality of lines; and setting the maximum line value to a highest numbered line having subtitle information when processing the plurality of lines.

34 . The computer-implemented method of claim 33 , comprising:
setting the default value for the minimum line value and the maximum line value to zero when processing the plurality lines in the top-to-bottom order; and setting the default value for the minimum line value and the maximum line value to a max value when the processing the plurality lines in the bottom-to-top order.

35 . The computer-implemented method of claim 32 , comprising:
determining whether a particular line of the plurality lines has subtitle information based on a summation of pixel of values for the pixels in the particular line.

36 . The computer-implemented method of claim 32 , comprising:
determining whether the subtitle information is in a top portion or a bottom portion of the subtitle image; and processing the plurality of lines in the top-to-bottom order when the subtitle information is in the top portion of the subtitle image and in the bottom-to-top order when the subtitle information is in the bottom portion of the subtitle image.

37 . The computer-implemented method of claim 35 , combining the new subtitle image comprising:
combining the new-subtitle image in a top portion or bottom portion of the video image based on whether the subtitle information is in the top portion of the subtitle image or the bottom portion of the subtitle image.

38 . At least one computer-readable storage medium comprising a plurality of instructions that when executed enable processing circuitry to:
determine a size of a subtitle area in a subtitle image comprising subtitle information; create a new subtitle image comprising the subtitle information, the new subtitle image having a same size as the size of the subtitle area and is smaller than the subtitle image; and combine the new subtitle image with a video image for presenting the subtitle information.

39 . The medium of claim 38 , comprising instructions that when executed enable the processing circuitry to:
process the plurality of lines in a top-to-bottom order or a bottom-to-top order; determine a minimum line value and a maximum line value in the subtitle image having subtitle information; and determine a number of lines between the minimum line value and the maximum line value to determine the size of the subtitle area.

40 . The medium of claim 39 , comprising instructions that when executed enable the processing circuitry to:
set the minimum line value and the maximum line value to a default value; set the minimum line value to a lowest numbered line having subtitle information when processing the plurality of lines; and set the maximum line value to a highest numbered line having subtitle information when processing the plurality of lines.

41 . The medium of claim 40 , comprising instructions that when executed enable the processing circuitry to:
set the default value for the minimum line value and the maximum line value to zero when processing the plurality lines in the top-to-bottom order; and set the default value for the minimum line value and the maximum line value to a max value when the processing the plurality lines in the bottom-to-top order.

42 . The medium of claim 39 , comprising instructions that when executed enable the processing circuitry to:
determining whether a particular line of the plurality lines ha
