Abstract: To eliminate unnaturalness in the display of video signals that are intermittently updated. Video signals recorded in a disk 1 in a compressed manner are reproduced through a pickup 2. The reproduced signals are fed to a reproduction processing unit 3 from where a bit stream is fetched which is then fed to a decoder circuit 4. The decoder circuit 4 produces video signals reconstructed from the compression. The signals from the decoder circuit 4 are fed to an adder 12 which is an adder means through an amplifier 11 which is a weighting circuit having a coefficient of, for example, 0.5. The added signal from the adder 12 is fetched to an output terminal 13, and is fed to a frame memory 14 which is a storage means of, for example, one frame. The signal stored in the frame memory 14 is fed to an adder 12 through an amplifier 15 which is a second weighting circuit having a coefficient of, for example, 0.5.

Abstract: Improved methods and arrangements are provided for use in selecting candidate television and multimedia programs for recording, recording the candidate programs, viewing the recorded programs, and archiving the recorded programs. At the center of this capability is a time-dependent content buffering arrangement that allows candidate programs to be selected by an intelligent content agent, with the assistance of a bubbling agent, an electronic program guide, a select library listing, and/or a personal profile associated with a particular user. The buffering arrangement selectively records candidate programs in a non-circular manner. Candidate programs may be dropped during recording based on certain information associated with the program. For example, examination of closed captioning information may reveal that the candidate program does not match the initial criteria for making it a candidate program.

Abstract: An image, which is captured by a camera that a worker, etc., carries, is once stored in a ring buffer memory for storing image signals. The image is extracted from the ring buffer memory, and a quasi-moving image is generated. In a normal state, the quasi-moving image is displayed on a monitor of a center such as a control room, etc. via codecs on transmitting and receiving sides. When a user viewing the monitor makes a request to view a sharp image of a particular frame, or the high-quality motion of a subject while viewing the frames preceding or succeeding a particular frame, the image frame or frames are read from the buffer memory for storing image signals, and displayed on the monitor.

Abstract: A digital video recorder can be used to allow users to fast forward through segments of a recorded video signal, such as commercial breaks, while still allowing the advertiser a limited opportunity to present an advertising message. Frames from the commercial recorded with the video signal are electronically tagged. When the processor of the digital video recorder finds a tagged frame or frames during a fast forward operation, the processor may display the tagged frame as a static image during the fast forward operation or may play the series of tagged frames at normal speed as a condensed video clip during the fast forward operation. Thus, through a static image or a condensed video clip, an advertiser can present an advertising message, while the user may still skip the full-length commercials as quickly as before.
