Abstract
The invention discloses a remote audio and video data transmission method. The method includes the steps that an interviewing device obtains two channels of video data and one channel of audio data; the two channels of video data and the one channel of audio data are coded and compressed and packed into an uplink audio and video data package; the interviewing device sends the uplink audio and video data package to a remote device through a remote communication network so that the remote device can play the corresponding audio and video data; the interviewing device receives a downlink audio and video data package sent by the remote device, wherein the downlink audio and video data package comprises one channel of video data and one channel of audio data, and the one channel of video data and the one channel of audio data are acquired by the remote device; the interviewing device unpacks and decodes the downlink audio and video data package, and the one channel of video data acquired by the remote device and the one channel of audio data acquired by the remote device are obtained and played. According to the remote audio and video data transmission method, simultaneous transmission of multiple channels of video of field scenes, scene personnel and remote control center scenes can be achieved, and meanwhile complicated programs and manpower cost are reduced; a video interactive mode is added, and therefore the requirements of all the scenes can be met.
Description
Technical field
The present invention relates to audio video transmission technical field, relate in particular to a kind of remote audio-video data transmission method.
Background technology
Along with mobile communication technology bandwidth improves, 3G/4G network has possessed the ability of bearing multimedia video data.Meanwhile, along with popularizing of internet video, increasing user has got used to watching ageing higher video content by the Internet.In addition, unidirectional video transmission mode can not meet the demand of types of applications scene, and user need to realize video two-way interactive in net cast process.
Existing net cast is used special picture pick-up device to gather video conventionally, receives and send audio frequency by microphone and earphone, and signal, by micro-letter or microwave line transmission, is realized the real-time Transmission of video.And the also two-way interactive of video He Yi road, a road audio frequency just of existing video two-way interactive, under some sight to realize effect unsatisfactory.For example the law enfrocement official such as municipal administration of public security organs, while exercising a public function at the scene, had both needed the video evidence obtaining of carrying out enforcing law to keep on file; While encountering specific question, wish again to obtain at the scene the guidance assistance of rear end Police Command Center.The and for example on-the-spot broadcasting of competitive sports, in the time of video two-way interactive, can only be the video interactive of field condition and remote equipment, or host's video and the video interactive of remote equipment, then adopts the forms such as multiwindow to splice on same display screen.
Existing audio video transmission mode is that a road video is to command centre, Field Force need configure a camera, when transfer of data owing to video flowing not being done to optimization process, use the mode of software codec simultaneously, so cannot accomplish the multiple video streaming in finite bandwidth, therefore cannot scene, Field Force and remote control center scene multi-channel video be propagated simultaneously simultaneously.In addition, because Voice & Video is separately propagated, likely cause scene and sound asynchronous, interactive mode is single, and leading portion personnel and rear end personnel can only pass through voice communication mutually.
Summary of the invention
The embodiment of the present invention proposes a kind of remote audio-video data transmission method, the multi-channel video that adopts the technical program can realize field scene, scene personnel and remote control center scene is propagated simultaneously, reduce numerous and diverse program and human cost simultaneously, increase video interactive mode, meet the needs of each scene.
The embodiment of the present invention provides a kind of remote audio-video data transmission method, comprising:
