摘要： Methods of operating a digital video recording and playback device, such as a video tape recorder, to arrange trick play data into one or more groups, to generate error correction bits for each group of trick play data, e.g., a group of trick play data blocks, and to correct the data after being read back using the error correction bits is disclosed. The trick play data blocks are made to be smaller than normal play data blocks with multiple trick play data blocks being equal in size to a single normal play data block. By making a group of trick play data blocks equal in size to a single normal play data block, the group of trick play data blocks may be processed as a unit by the same error correction circuitry and in the same manner used to process individual normal play data blocks. In accordance with one embodiment, the error correction bits for a group of trick play data blocks are calculated treating the data in the group of trick play data blocks as a single unit. The error correction bits are appended to the last data block in the group of trick play data blocks. During trick play operation the trick play data blocks are read back and combined according to trick play data groups. Each group of trick play blocks is then processed using the same error correction circuitry used to process a normal play data block.

摘要： A digital video tape recorder ("VTR") that selects data useful for generating images during trick playback operation and records the data in trick play tape segments arranged on a tape to form fast scan tracks and multi-speed playback tracks. Each fast scan track comprises trick play tape segments located on a diagonal, relative to the length of the tape, of the same angle as the angle at which the heads of a VTR are expected to pass over the tape during trick play operation at a specific speed and direction of operation. Each multi-speed playback track comprises a plurality of trick play tape segments arranged parallel to the length of the tape. Data which is used for at least one mode of trick play operation is recorded in each trick play tape segment. Each fast scan track and multi-speed track crosses multiple normal play tracks. During playback at a wide variety of speeds and directions, the heads pass over enough trick play segments of the multi-speed playback track to generate recognizable images during trick play operation. Data is recorded in each trick play segment in a manner that optimizes the amount of data that can be routinely recovered during trick playback operation despite tracking errors.

摘要： Digital video tape recorder apparatus that generates commands to instruct a television receiver to perform special processing, e.g., processing designed to enhance image quality, on video data received from the digital video tape recorder during trick play operation is disclosed. The commands from the video tape recorder inform the television receiver that the video tape recorder is operating in trick play mode and that video processing not performed on normal play video data output by the video tape recorder during normal play operation should be performed on the trick play video data which is output during trick play operation. The video data output during trick play operation is a subset of the normal play video data. The video processing commands output during trick play operation instruct a receiver to perform video processing intended to compensate for normal play data intentionally omitted by the video tape recorder from the trick play video data because of, e.g., data limitations resulting from the limited amount of data that can be accurately read from a tape during trick play operation. Method of generating the video processing commands which are output to a receiver during trick play video tape recorder operation are also disclosed.

摘要： A video recorder compatible receiver for receiving video data from a video recorder such as a video tape recorder ("VTR"). The receiver includes an error concealment circuit, a digital VTR port adapted for coupling to a VTR and/or a tuner module. The receiver receives digital video data from the VTR by either the digital VTR port or the tuner module. VTR commands may also be received from a VTR. Upon receiving a VTR command indicating that the VTR is operating in trick play mode or upon detecting video data that is indicative of VTR trick play operation, the error concealment circuit of the receiver disables normal play error concealment and enables trick play error concealment. The error concealment circuit may perform temporal and spatial filtering on the video data received from the VTR when trick play error concealment is enabled.

摘要： A defect compensation circuit of the type that substitutes a portion of delayed signal information for a real-time signal defect including circuitry for correcting chrominance phase reversal. The delayed signal is sampled at 1/2 the period of the chrominance before and after a 1H delay. The signal samples are summed and proportioned to provide a substitution signal having its chrominance signal in phase with the real time signal, and an average luminance signal exhibiting non-observable distortion.

摘要： Apparatus for controlling various functions of a television receiver such as the picture and audio responses includes a keyboard with numbered keys which are normally used for selecting channels and a program key. When the program key is pressed, an on-screen character generator is caused to display a numbered list or menu of the various functions to be controlled. Thereafter, a particular function can be selected for control by pressing the correspondingly numbered key. This causes the numbered list or menu of the characteristics of the selected function, e.g., the brightness, contrast, sharpness, color level and color tint of the picture, to be displayed. Thereafter a particular characteristic can be selected for control by pressing the correspondingly numbered key.

摘要： Apparatus is disclosed for reducing unwanted jagged diagonal artifacts in a video signal. At an encoder, moving image information is intraframe averaged over a given frequency range, e.g., above 1.5 MHz, while still image information is subjected to a field repeat process over a given frequency range. At a decoder, still image information is subjected to a frame repeat process over the given field repeat frequency range, while moving image information is left unchanged.

摘要： In a widescreen signal encoding system for a television-type signal, side panel chrominance information is conveyed in double sideband form on an auxiliary subcarrier having a field inverting phase relative to the phase of a standard chrominance subcarrier. Side panel high frequency luminance information exclusive of low frequency information also is conveyed on the auxiliary subcarrier, but in single sideband form. Illustratively the auxiliary subcarrier is at the 3.58 MHz frequency of the standard chrominance subcarrier.
