Abstract

The invention relates to a portable video recorder system. This system comprises a video shooting part including an image capturing device, video compression means, a buffer memory filled by the output of the video compression means and low data rate wireless transmission equipment having a short range, and a recording part including a reception equipment and a cassette, or tape, or disk, or solid state memory recording unit. Means are provided for the simultaneous wireless transmission of data from the memory of the capturing device and the filling of this memory.

Claims (6)

1. A portable video recorder system comprising:

a video shooting part including an image capturing device for shooting scenes, video compression means connected to said capturing device, said video compression means compressing audio and TV data according to the required standard, a buffer memory filled by the output of the video compression means and low data rate wireless transmission equipment having a short range for transmitting the data of the buffer memory with a low data rate, and

a recording part including a reception equipment comprising a reception antenna which provides through a communication interface the received data to a buffer memory and a cassette, or tape, or disk, or solid state memory recording unit which receives data from the buffer memory at a higher rate than the wireless transmission.

2. A portable video recorder system according to claim 1 , wherein the low data rate transmission equipment of the video shooting part has a transmission rate which is about 10 times less than the data rate of filling of the buffer memory of this video shooting part.

3. A portable video recorder system according to claim 1 , wherein the data rate of the wireless transmission equipment is about 2 Megabits per second.

4. A portable video recorder system according to claim 1 , comprising means for audio detection and storing into the buffer memory of the shooting part and for transmission together with video data.
