Embodiment Construction

[0017] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] refer to Figure 5 , the video recording system according to the present invention includes at least two cameras CA1 and CA2 at different angles. The first camera CA1 includes four microphones M1-M4 and the second camera includes four microphones M5-M8. It can be understood that the number of cameras can be freely changed according to the user's arrangement.

[0019] refer to Figure 6 , The video recording apparatus according to the present invention includes first and second video encoders 30 and 32, first and second audio encoders 34 and 36, multiplexer 38, and digital recorder 40.

[0020] refer to Figure 7 , The video playback apparatus according to the present invention includes digital playback means 42 for reading first and second video stream data and first and second audio stream data, which have been compressed and recor...

Abstract

A digital video playback apparatus selectively reproduces video signals which are recorded by using a plurality of cameras at different angles. A digital playback apparatus reads out video stream data and audio stream data, which are compressed and recorded on a recording medium. A demultiplexer separates a signal output of the digital playback apparatus into system information. First and second video decoders expand the first and second compressed video stream data outputs. First and second audio decoders decode the first and second audio stream data outputs from the demultiplexer and expand the first and second audio stream data decoded into original 4-channel audio signals, respectively. A key input section generates first and second angle selection signals. A controller analyzes the system information and generates a switching control signal. First and second switches selects the first and second video and audio stream data according to the switching control signal.

Description

technical field [0001] The present invention relates to a digital video reproducing device in a digital video device, and more particularly to a digital video reproducing device for reproducing video and audio signals recorded by a plurality of cameras at different angles. Background technique [0002] Such as figure 1 As shown, in the case of tracking a moving image or music video, a camera is placed in front of the target, and four microphones SL (surround left), SR (surround right), FL (front left) , and FR (front right) are set around this target to keep the sound coming. Audio and video signals from microphones and cameras pass through figure 2 The known video signal recorder shown is recorded on a recording medium such as a disc. [0003] refer to figure 2 , the multiplexer (MUX) 14 receives system information including the number of video blocks, the number of audio blocks, the start address of the video block, and the start address of the audio block. The vide...
