Embodiment Construction

[0024] The VCR system shown in the accompanying drawings consists of two parts:

[0025] The first section 10 is used for audio and video photography and the second section 20 is used for audio and video cassette recording.

[0026] The first part 10 has a very low weight so that it can be carried optimally on the forehead. The first part 10 comprises a conventional image capture device 12 provided with a lens and microphone (not shown). The image is detected by a CCD detector. Video and audio compression means 4 receive audio and TV data and compress them, for example according to the MPEG2 or MPEG4 standard.

[0027] The audio and video compressed data are provided to a buffer memory 16, for example, having a capacity of 1 gigabit, and the data in the buffer memory 16 are provided to a communication interface 18, so that they can be transmitted at a very low data rate through a transmitting antenna 19. data. The transmitting device has a small transmission range to avoid...

Abstract

The present invention relates to a portable video recorder system. The system comprises a video camera part (10) comprising an image capture device (12), video compression means (14), and a buffer memory (16) filled by the output of the video compression means, and Short distance low data rate wireless transmitting equipment (18, 19), and recording part (20), including receiving equipment (22, 24) and cassette tape or magnetic tape, or magnetic disk, or solid state memory recording unit (28). Means for simultaneously wirelessly transmitting data from the memory of the capture device and filling the memory are preferably used.

Description

technical field [0001] The present invention relates to a portable video recorder system. Background technique [0002] Video players currently available on the market are very light in weight. And they also work automatically. Therefore, using a camcorder is quite easy. However, one pair of hands must be used to control the operation of the camcorder. This is inconvenient for some uses of the camcorder, for example if the user wishes to be able to simultaneously record written notes while he is photographing a scene. [0003] This is why it is proposed to separate the image capture part from the processing and recording part. In fact, the mechanical recording part consumes the most power and is the heaviest part of the camcorder. In this case, the first part comprising the image capture device and the buffer memory is very light and can be freely carried, eg on the forehead. After photography, the buffer memory can be used to transfer the recordings to a cassette or m...
