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 (220), a digital VTR port (206) adapted for coupling to a VTR and/or a tuner module (204). The receiver receives digital video data from the VTR by either the digital VTR port (206) or the tuner module (204). 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 (224) and spatial (222) filtering on the video data received from the VTR when trick play error concealment is enabled.

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. During specific speeds of playback operation supported by the use of fast scan tracks, data read from the fast scan tracks provide images of better quality than data that can be read from the multi-speed track. 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： Methods and apparatus for reducing the complexity of decoder circuitry and video decoder memory requirements are disclosed. The discribed video decoders are capable of decoding HDTV and/or SDTV pictures. The described video decoder may be used as part of a picture-in-picture decoder circuit for providing picture-in-picture capability without providing multiple full resolution video decoders. The reduction in decoder circuit complexity is achieved through the use of a plurality of data reduction techniques including the use of a preparser, downsampling, and truncating pixel values.

Normal play and trick play tape segments may be arranged to form normal play tracks on the tape, each fast scan track crossing multiple normal play tracks. The playback circuit includes a packet filter, a trick play servo control circuit and a VTR command generator circuit. The packet filter reads packet headers of data packets read from the tape and outputs only data packets intended for use during a user selected mode of VTR operation. The trick play servo control circuit controls tracking so that the heads pass over the fast scan tracks at the correct location and angle. The VTR command generator generates commands to a receiver indicating when the VTR is in trick playback mode.
