Detailed Description

Please refer to fig. 1 and fig. 2, which are schematic views of an appearance of the present invention and a block of the present invention, respectively. As shown in the figure: the utility model relates to a multimedia transmission device without a channel switcher, which comprises an image acquisition unit 1, a plurality of video and audio providing units 2 and a playing unit 3.

The image acquisition unit 1 includes an audio/video processor 11, a plurality of channel input ports 12 and at least one channel output port 13 for receiving the audio/video signal 4, performing audio/video integration processing to obtain an audio/video playing signal, and outputting the audio/video playing signal 5 after the integration processing.

Each video providing unit 2 is connected to each channel input port 12, and each video providing unit 2 can provide video/audio signals 4 to the image capturing unit 1 through each channel input port 12, so that the image capturing unit 1 integrates and processes each video/audio signal 4 into the video/audio playing signal 5.

The playing unit 3 is connected to the channel output port 13, and can receive the video playing signal 5 outputted from the channel output port 13 and play the video playing signal 5.

When the device is used, the video and audio signals 4 can be provided to the image acquisition unit 1 through the video and audio providing units 2 respectively through the channel input ports 12, so that the video and audio signals 4 are received by the image acquisition unit 1 and then are integrated and processed into the video and audio playing signal 5 through the image acquisition unit 1, the video and audio playing signal 5 is output to the playing unit 3 through the channel output port 13, and the video and audio playing signal 5 is played by the playing unit 3. Therefore, the integration of a plurality of audio/video signals 4 can be directly performed, and the integrated signals can be played without additionally establishing channel switching equipment, thereby achieving the effects of easy use, quick integration and cost reduction.

In an embodiment of the present invention, the audio/video processor 11 can receive the audio/video signals 4 provided by the audio/video providing units 2, integrate and process the audio/video signals 4 into the audio/video playing signal 5, output the audio/video playing signal 5 to the playing unit 3 through the channel output port 13, and play the audio/video playing signal 5 by the playing unit 3.
