Substituting Embedded Text for Video Text Images
During encoding, blank frames may be substituted for text images in video content, encoding the blank frames instead of the text images. The text images may be any kind of text images such as opening credits, ending credits, and so on. The selection of text images to substitute may be performed by optical character recognition, user selection and so on. The text associated with the text images may be embedded in the encoded video. If the text is already embedded, an indicator of the location may be added. If not, the text may be derived from the text image using optical character recognition and then embedded. When decoded, the encoded video may be analyzed to determine whether blank frames were substituted for text images. Embedded text associated with the text images may then be located, obtained, and added to the decoded video. Thus, the original text images are essentially reconstructed.

decoding encoded video content utilizing at least one processing unit;
determining, utilizing the at least one processing unit, that at least one frame of the video content is a blank frame encoded instead of at least one portion of video content that includes at least one text image; and
adding text to the decoded video content utilizing the at least one processing unit, wherein the text is obtained from embedded text in the encoded video content and the text corresponds to the at least one text image.
9 . The method of claim 8 , wherein said operation of adding text to the decoded video content utilizing the at least one processing unit further comprises obtaining the text from the encoded video content utilizing at least one indicator associated with the at least one blank frame that indicates at least one location of the text embedded in the encoded video content.

12 . The system of claim 10 , further comprising at least one input component wherein the at least one processing unit selects the at least one portion that includes the at least one text image based on at least one user input received via the at least one input component.
13 . The system of claim 10 , wherein the at least one processing unit determines that text corresponding to the at least one text image is already embedded in the video content and incorporates at least one indicator into the encoded video content that specifies at least one location of the text embedded in the encoded video content.
14 . The system of claim 10 , wherein the at least one processing unit incorporates at least one indicator that specifies that the at least one blank frame is encoded rather than the at least one portion.
15 . The system of claim 10 , wherein the at least one processing unit determines that text corresponding to the at least one text image is not already embedded in the video content and embeds the text in the encoded video content.
16 . The system of claim 15 , wherein the at least one processing unit derives the text to embed in the encoded video content by performing optical character recognition on the at least one text image.
17 . The system of claim 10 , further comprising a content receiver, comprising:
at least one communication component that receives the encoded video content from the at least one output component; and
at least one processing unit that decodes the encoded video content;
wherein the at least one processing unit detects the at least one blank frame, obtains the embedded text, and adds the obtained text to the decoded video content.
18 . The system of claim 17 , wherein the at least one processing unit obtains the embedded text from the encoded video content utilizing at least one indicator associated with the at least one blank frame that indicates at least one location of the embedded text in the encoded video content.
