Abstract
This invention relates to a transferring method for video images including: collecting video signals to a computer from a digital camera, compressing and converting the video signals in the computer to MPEG form to get the converted file to be delivered in E-mail via Internet, the E-mail is received and the video file is downloaded to the local place.
Description
Technical field
The present invention relates to a kind of transfer approach of video image, particularly a kind ofly pass through the Internet method for transmitting TV news image between foreign lands at what TV station broadcast to need.
Background technology
The transmission of television image can realize by transmission means such as microwave, optical cable, marine satellites between the strange land, and be widely used in CCTV, in the image transmission work of numerous provincial TV stations.Unidirectional, transmission step by step that microwave transmission is generally passes the platform toward subordinate by higher level's platform; The expense costliness that marine satellite transmits is used complexity, and every cover maritime satellite system price is about 500,000 yuan, also has expensive communication expense in addition; Optical fiber transmits and generally is used for subordinate's platform at present to higher level's platform transmission news image, realize between any two places that it is big that particularly local and overseas mutual biography news images transmit difficulty, the expense height.These transfer approachs are for the relative more weak prefecture-level TV station of technical equipment strength, often can't be, the city is overseas even in time pass news scene overseas back from province, and the same day, news can't return broadcast the same day, caused the TV news timeliness not strong.
Summary of the invention
The purpose of this invention is to provide a kind of low input, flexible and efficient, easy to operate, the ageing strong the Internet method for transmitting TV news image between foreign lands that passes through.
The object of the present invention is achieved like this: a kind of by the Internet method for transmitting TV news image between foreign lands, it may further comprise the steps: a, vision signal is collected computer from digital camera; B, the video signal compression in the computer is converted to mpeg format, the file after obtaining changing; C, the file after will changing by the Internet transmit; The video file that d, reception transmit downloads in the local computer.When being collected computer from digital camera, vision signal gathers by 1394 interfaces.When being changed, the video signal compression in the computer adopts the MPEG2 form.The invention still further relates to by the application of the Internet method for transmitting TV news image between foreign lands in TV station's news is broadcasted.
Provided by the present invention by the Internet method for transmitting TV news image between foreign lands, because the method that has adopted collection, compression and transmitted by the Internet, do not need to transmit the news image in real time by transmission means such as microwave, optical cable, marine satellites, drop into low, flexible and efficient, easy to operate, improved the ageing of TV station's dissemination of news.
Embodiment
Embodiment: take by digital camera, as PD150 of Sony etc., video camera is connected with the computer that has 1394 interfaces, by 1394 mouthfuls of images of gathering the AVI form, because the image per minute vision signal of AVI form will take 200,000,000 space at least, under existence conditions, have any problem by the Internet transmission, so being edited the back, the AVI formatted file is converted into MPEG1 or MPEG2 form by compressing and converting software, the MPEG1 form is the form that VCD adopts, it is bad to broadcast effect in TV station, and MPEG2 format video signal picture pixel is 720 * 576 pixels, meets current TV fully and broadcasts requirement.The form of file after the compression with e-mail attachment sent by networking, download to local computer after the mail reception and again this file is called in the non-line editing system of TV station, can edit, broadcast.
Gather, can adopt popular " in graphic detail " software for editing when editing, after similar video editing software compressions such as " in graphic detail " " product Buddhist nun height ", 1 minute AVI video signal compression is that size is about 40,000,000 behind the MPEG2 form, and size is about 10,000,000 behind the boil down to MPEG1 form.The E-mail address should be selected the big capacity mailbox of the annex transmitting function that can be provided at for use, needs to possess the big capacity mailbox of 30M attachment function at least.Because the size of single annex can not surpass the annex size that mailbox can provide, be noted that in editor that therefore if the mailbox of 30M annex, each MPEG2 video file duration of compression generation should not be above 40 seconds.By the said equipment and operating procedure, editor has generated one section MPEG2 video file of 40 seconds, and size is 29M, if be generated as the MPEG1 form, size is about 7M, but because picture quality obviously is worse than the MPEG2 form, does not recommend to use.By the E-mail address annex, file is sent, under the situation of using the broadcasting and TV broadband networks, the mail of 29M size sends and has used 6 minutes, and the mail annex is downloaded and has been used 4 minutes.
If enough memory spaces are arranged on the internet, we can not send by Email yet, and the file after will compressing directly is stored on the net, is not subjected to the restriction of e-mail attachment size, sends bigger video file.
