Problems solved by technology

However, if one of these frames is changed by inserting or overlaying a different video image, the synchronization between the decoder and the original encoder is broken
Therefore, if a region of an image is coded using a motion vector that straddles the boundary between a modified region of the image and an unmodified region, the motion prediction process will fail

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.

Description

[0001] This application claims the benefit of US Provisional Application No. 60 / 845,707, filed September 18, 2006, which is incorporated herein by reference and forms a part hereof. technical field [0002] The invention relates to the field of video processing. More specifically, the present invention provides methods, devices and systems for inserting overlay content into a video signal. Additionally, certain example embodiments of the invention are directed to inserting overlay content into a video signal during transrating of the video signal. Background technique [0003] Today's television images are often overlaid with additional content (referred to herein as "overlay content"), such as text messages, logos, animations, or sub-windows representing full-motion video. Such edited signals may be used to convey urgent information, targeted advertisements, or to customize messages associated with full-screen programming or advertisements. There may be more than one cand...
