Abstract: A method and system for decoding and storing encoded control data delivered via the horizontal overscan area of a video signal. An interactive device performs behavior defined by control data encoded into a video signal that can be broadcast or played-back from video tape. The interactive device is equipped with a non-volatile memory that permits the control data to be stored for performance subsequent to, or during, the transmission session.

Closed caption signals are created by remote closed caption generating systems that are connected to an input device, such as a stenography keyboard or voice recognition system. The closed caption signals are generated at multiple remote closed caption generating systems and in different languages, and are then independently transmitted to a multiplexing system where they are properly identified and blended into a single output data stream. The single output data stream is then delivered to a closed caption encoding device via a connection such as an Ethernet or serial connection.

Abstract: Disclosed is a system and method of combining traditional programming caption data with advertising caption data in a single closed caption data stream. Advertising caption data is received from a data warehouse. When such advertising caption data is encoded into the closed caption data stream, it must temporally displace the traditional programming caption data that would otherwise be displayed. Thus, such programming caption data is buffered during display of the advertising caption data, and then is played out in an intelligent yet accelerated manner to maintain readability and recover the time lost during the sponsorship event.

Abstract: A system, method, and computer readable medium for avoiding underflow of a caption buffer in a digital video encoding device. The method receives a sequence of digital video frames, and captions that correspond to the digital video frames in the sequence. The method receives first captions in a first caption carriage, and encodes the first captions, and the corresponding digital video frames, in a compressed video format. The method detects a switch from the first caption carriage to a second caption carriage, and stores second captions in the capture buffer, where each second caption is received in the second caption carriage and corresponds to one of the digital video frames in the sequence. The method examines the capture buffer and the second captions to determine whether underflow of the capture buffer is present or absent. When underflow is absent, the method encodes the second captions, and the corresponding digital video frames, in the compressed video format.
