Abstract
Methods, apparatus, and systems for inserting overlay content into a video signal are provided. An overlay content signal containing overlay content is received. In addition, a compressed video signal is received from a video source and decoded. An insertion window portion of the decoded video signal is identified. The overlay content signal and the insertion window portion of the decoded video signal are processed to produce a modified insertion window portion of the video signal. The video signal and the modified insertion window portion are then processed to produce a modified video signal. The data rate of the video signal may be modified during the overlay content insertion process.
