Abstract:
A video signal recording apparatus for recording a digital video signal on a plurality of tracks on a magnetic medium, each of the tracks representing a trace of a single recording head across the magnetic medium and having a video data region and an auxiliary data region,wherein the digital video signal includes first data representing pixels in a first region of a display device and second data representing pixels in a region of the display device, other than the first region, the first data of the digital video signal is recorded on the video data region, and the second data of the digital video signal is recorded on at least a part of the auxiliary data region;the video signal recording apparatus comprising:a first encoder for receiving and high-efficiency encoding the first data representing pixels in the first region, thereby generating compressed first data;a recorder for recording the compressed first data and the second data on the magnetic medium, anda replacing circuit coupled to the recorder, the replacing circuit receiving the second data and an auxiliary signal, the auxiliary signal including third data which contains information related to the first data and the second data in the digital video signal,wherein, upon receiving the second data, the replacing circuit replaces at least a first part of the third data corresponding to the auxiliary signal with the second data and provides the second data and a second part of the third data which is not replaced with the second data to the recorder for recording on the recording medium, andthe recorder further records the second part of the third data which is not replaced with the second data by the replacing circuit.
