Embodiment Construction

[0084] A first embodiment of the invention is shown in Figure 2a middle.

[0085] The main components are shown in Figure 2a The digital video recorder in includes an analog source 112 and a digital source 114 as the first circuit 100 . Analog source 112 is typically an analog tuner that receives an analog video signal from a remote transmitter via an antenna combined with a demodulator, or it may be, for example, the output of a conventional analog VCR. Analog source 112 generates a baseband analog video signal.

[0086] Digital source 114 may be a digital tuner receiving a video signal from an antenna or cable link, for example digitally encoded according to MPEG-II format. This type of digitally encoded signal (or digital stream) is already widely used for video signals received from satellites and in the future should even be used for terrestrial communications (new HDTV standard). Another example of digital source 114 is a hard disk drive (HDD).

Abstract

A video apparatus has a first circuit(for instance an analog recording and reproducing unit)generating a first baseband analog video signal on a first output. A second circuit(for instance a video decoder), at least connectable(for instance through a path switch)to the first output, can digitize the first baseband analog video signal and process and output a corresponding digital stream on a second output. The second output is in turn at least connectable(for instance through a digital switch)to a third circuit(for instance a video encoder)generating on a third output a second baseband analogvideo signal on the basis of the digital stream. Processes to take advantage of this structure are proposed.

Description

technical field [0001] The invention relates to a video device, in particular a video recorder, and to a method for said video device. Background technique [0002] A video device is a device that contains circuitry to process video signals. Among such devices, a video recorder is a device that records a video signal on a medium. [0003] Known solutions to video recorders, such as disclosed in U.S. Patent No. 5 504 632 and European Patent Application No. 0 671 855, have figure 1 The general structure shown. A video signal (eg CVBS) from an analog source 2 is sent to both an analog recording and reproduction unit 4 and a digital recording and reproduction unit 6 . [0004] The analog recording and reproduction unit 4 can record the video signal from the analog source 2 on magnetic tape according to a given analog standard, ie without digitization, for example according to the VHS or S-VHS format. [0005] The digital recording and reproduction unit 6 can record the video...
