Problems solved by technology

Even in the case where a digital video signal of a system other than the MPEG2 system is input to the IRD, the input signal cannot be decoded in the IRD, and the reproduced picture cannot be displayed on the TV receiver through the IRD
Therefore, there is a possibility of confusing the user

Embodiment Construction

[0027] According to the first embodiment, in the case of reproducing a cassette which cannot be correctly displayed by the IRD like an analog-recorded program, a warning display is performed, thereby enabling the user to switch video input appropriately.

[0028] According to the second embodiment, in the case of reproducing a tape cassette, by displaying the recording system, recording time, program information, etc. of each program recorded in the tape cassette, it is determined that the program that the user wants to reproduce and monitor has been analog-recorded Also digitally recorded, which television broadcast signal has been recorded, additionally identifies program content, etc., and alerts the user to switch video inputs appropriately for reproduction and monitoring of the desired program.

[0029] First, the structure of that part of the system common to the first and second embodiments will be described in detail below.

[0030] In FIG. 1, reference numeral 1 denot...

Abstract

An apparatus capable of performing both analog recording / reproducing and digital recording / reproducing on / from the same video tape, which issues an alarm if a tape cassette containing a tape on which video is recorded in analog form is loaded to reproduce the video. Further the apparatus issues an alarm if a tape cassette containing a tape on which transport streams of different specifications or digital signals of a recording method other than the MPEG2 method are recorded is loaded to reproduce them. The apparatus reads information about the recording method of the program which the user wants to view referring to the smart file image. If the program to be reproduced is recorded in digital form, the apparatus changes its input to the digital video input; and if the program is recorded in analog form, the apparatus changes its input to the analog video input.

Description

technical field [0001] The present invention relates to a program receiving device, for example, a receiving device for digital broadcasting in a digital broadcasting system, and to a method of recording and displaying program-related information. Background technique [0002] In recent years, IEEE (Institute of Electrical and Electronics Engineers) 1394 has begun to be extended to an interface for high-speed transmission of video data or audio data between digital video devices or between digital audio devices. According to IEEE1394, both the isochronous transfer mode and the asynchronous transfer mode are supported. In the isochronous transfer mode, the delay time of transfer is guaranteed, which is suitable when used for high-speed transfer of a data stream that is continuous with respect to time, such as video data or audio data. In the asynchronous transfer mode, it is ensured that the data can be sent to the participating destination, which is suitable when the user m...
