Abstract
A video recording medium, video signal processor, and method are provided. The video signal processor includes a transcoder for receiving a video input signal comprising a plurality of input signal frames, each of the input signal frames including at least one of intraframe data and interframe data, and for constructing a corresponding plurality of system frames from the input signal frames, each of the system frames having a fixed length and including a first portion, having a first fixed length, including intraframe data and excluding interframe data, and a second portion, having a second fixed length, including interframe data and excluding intraframe data. By using a fixed system frame length, by using fixed lengths for the intraframe and interframe data segments, and by appropriately positioning these segments on respective recording tracks, the recording heads record only intraframe data from the sequential recording tracks as the heads diagonally traverse the tracks along their trick mode head trajectory during trick mode operation. The intraframe data thus read can be used directly to produce a display of a TV image which, although imperfect, is acceptable to the viewer.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
