Encoded video recorder/player timer preprogramming information listed in a television calendar allows a timer preprogramming feature on a video cassette recorder VCR to be programmed using a compressed coded indication of as few as 1 to 8 digits, which are decoded by a decoder built into either the video cassette recorder or a remote controller to convert the compressed coded indication into channel, date, time and length information. The channel, date, time and length information is communicated to a VCR and used to automatically activate the VCR to record a given television program with the corresponding channel, date, time and length. Alternatively, the channel, date, time and length information is decoded directly in a remote controller and only start record, stop record and channel selection commands are sent to the VCR at the appropriate times. An encoder, which may be implemented on a computer, is used to generate the compressed coded indications. The compressed coded indications associated with each television program can be printed in a television program calendar in advance and used with a VCR or remote controller with the decoding means. Algorithms for decoding the compressed codes can be a function of time to ensure security of the decoding method.

A system, method, and computer-readable medium which reduce the occurrence of incomplete recordings of television programs by video cassette recorders (VCR) (130), or other types of video recorders, by adding margins (6, 7) to the programmed start and end times (1, 2) of the recording. The margins (6, 7) cause the recording to start earlier than the programmed start time (1) by a specified amount of time (DELTATB), and to stop later than the programmed stop time by another specified amount of time (DELTATE). Therefore, when a television program starts a few minutes earlier, or ends a few minutes later than scheduled, the present invention helps ensure that the entire television program will be recorded by the video recorder, despite the fact that the video recorder was programmed in accordance with to the scheduled times (1, 2).

An apparatus and method for applying anti-copy protection to a raster-scanned video signal are described. A square waveform 52 is added to the vertical synchronisation pulses 50 of the video signal. The effect of the waveform is not apparent until it has been recorded by a video cassette recorder. The anti-copy protected video signal can therefore be viewed normally on a display device at or near to the picture quality intended by the originator of the video signal, but once recorded, exhibits a reduction in picture quality which makes the video signal quite unattractive to view.

The video and graphics system includes a video decoder for decoding MPEG-2 video data. The video images may not be downscaled in the horizontal direction when no bi-directionally predicted pictures are used. The video and graphics system may output an HDTV video while converting the HDTV video and providing as another output having an SDTV format or another HDTV format. The output having an SDTV format may be recorded using a video cassette recorder (VCR) while the HDTV video is being displayed.

A method and apparatus is disclosed for encoding secondary signals, such as audio signals, within a television signal in a manner such that the signal may be either recorded on a video cassette or broadcast. The audio samples are encoded only on selected lines of each video frame which do not interfere with dedicated broadcast and cable lines and are not affected by head switching of a video cassette recorder. The audio samples are encoded only within an overscan portion of the selected lines such that the encoded samples do not interfere with other portions of the video signal. However, by encoding the samples within the overscan portion, the samples do not affect the displayed image. The secondary audio signal is sampled during equally spaced intervals throughout the video frame, then compressed and encoded only within selected horizontal lines. During decoding, the audio samples are decompressed and played back at the original sampling rate to provide audio playback
