Description
Technical field
The present invention is relevant a kind of personal pocket broadcast relay system, be meant especially a kind of have auto-control software can be according to the communication frequency that detected compact model and transmission rate with decision institute transmitting audio-video data, can not need heavy transmitting and receiving device, just audiovisual materials can be seen through 3G (thirdgeneration) or world-wide web, do audio-visual transmission and broadcast, fully satisfy the mobility and the telepresenc requirement of relaying, reach and reduce the relay devices volume, and save the purpose of relaying cost.
Background technology
What relay job requirement is instantaneity, mobility and telepresenc, traditional relay is to utilize the band mode of running, send audiovisual materials and bring to retransmission site, yet this kind relay mode is as if shooting with video-corder place and retransmission site at a distance of too far away, in delivery process, often lost the gold period that message is propagated, the value of relay and interests are reduced.
Run for improving the disappearance that band is sent audiovisual materials, relay work has to change with " microwave " and transmits audiovisual materials, and microwave is a kind ofly to have high frequency and (be generally that 300MHz～300GHz), wavelength is very short, is generally the electromagnetic wave of 1m～1mm.At microwave frequency band, because frequency is very high, a little less than the diffracting power of electric wave, so the transmission of signal mainly is to utilize the straightline propagation of microwave in line-of-sight distance; This circulation way is propagated fast though have, can strive for the advantage of timeliness; But in the communication process of electric wave, but be subjected to landform unavoidably, the influence of atural object and climate condition and cause reflection, refraction, scattering and absorbing phenomenon produce and propagate decline and propagation distortion, use still to belong to difficulty, inconvenient.Along with the renewal of propagating science and technology, develop " SNG " (the Satelite News Gathering) that utilizes satellite transmission on the practice and transmit audiovisual materials, can not be subjected to the influence of landform, audiovisual materials are passed to retransmission site immediately clearly, reach the instantaneity requirement of relay.
Though yet this kind relay mode is very convenient, still has following disappearance:
1. " SNG " required relay devices is very expensive; Single the often several hundred million easily units of " SNG car " (satellite transmission car) that confession transmits cause the very big burden of relaying cost.
2. " SNG " line employed " SNG car " volume is very heavy, only is adapted at the place broadness and the SNG car is checked and approved the place of sailing into, just can do on-the-spot instant wiring; If shoot with video-corder occasion is in some narrow space or the dangerously steep place of physical features, " SNG car " can't enter, and often still needs audiovisual materials to be delivered to the SNG car of closest approach in traditional race band mode, could see through satellite audiovisual materials are passed to retransmission site, make the use of " SNG " produce limitation.
3. on the fortune mirror, " SNG " because unit often, the fortune mirror also just can't be lively, and can walk about everywhere when interview is photographed on ordinary days differs widely.Therefore one " SNG " relays, and what spectators may see is the content of poorness and stiff camera lens, loses telepresenc.
Because above-mentioned all existing relay modes all have tangible disappearance, the present invention is to use 3G (thirdgeneration) action network, and (its core technology is a kind of package IP (world-wide web agreement) technology, can allow the user continue to reach the standard grade, at any time link) or use world-wide web to transmit, improve the disappearance of existing broadcast relay system when actual using.
3G (third generation) is the abbreviation of third generation Mobile Communications.It is a kind of emerging wireless communication technique, can retrieve the Internet services immediately at a high speed, will break divide in the past communication, information, medium and amusement between old boundary, with all service assemblies; Along with the development of the wireless new technology of 3G, just do not allow application program be able to high speed transmission data, more can take into account convenience and the retrieval rate that improves data.
This case is invented into having and is supervised in the disappearance of above-mentioned existing broadcast relay system during in actual using, and accumulation individual is engaged on the related industry exploitation practice experience for many years, study intensively, kind advantage innovation and application with existing world-wide web and 3G action network, a kind of personal pocket broadcast relay system of developing finally.
The sender can transfer to the audiovisual materials that audio-visual shooting main machine is shot with video-corder the audiovisual materials platform, the recipient can only be seen through by a received signal media, the receiving system that one decompression scheme and a repeater are formed, no matter be in any place, any time, can both be linked to the purpose terminal retrieval digit audio-visual data of network, again this digit audio-visual data is changeed shelves via this decompression scheme, and utilize repeater to play back, and this received signal media can be wireless or wired, this repeater can be running gear (Mobile Devices), 3G mobile phone (3GWreless), interactive device (Interactive Devices), the high image quality DVB-T, TV and computer etc. are no longer limited to the reception form of audiovisual materials.
Summary of the invention
Main purpose of the present invention, aim to provide a kind of personal pocket broadcast relay system, be to utilize the auto-control software can be according to the communication frequency of the purpose terminal of the audiovisual materials platform that detects to determine the compact model and the transmission rate of institute's transmitting audio-video data, do the transmission of audiovisual materials, do not need heavy transmitting and receiving device, reach and reduce the relay devices volume, and save and relay cost, and fully satisfy the requirement of instantaneity, mobility and the telepresenc of relaying.
For reaching above-mentioned purpose, the present invention comprises: a transmitting device is to be an IEEE1394 interface, the digital type audiovisual materials that transmission is shot with video-corder; One auto-control software is compact model and the transmission rate of the communication frequency of testing goal terminal with decision institute transmitting audio-video data; One audio-visual search mechanism converts the audiovisual materials that voltage supply is contracted to but the audiovisual materials that this IEEE1394 interface can be transferred out see through this audio-visual search mechanism; One audio-visual condensing routine is that above-mentioned audiovisual materials are compressed into formative digit audio-visual Datagram; One numerical digit is shifted to new management mechanisms, be to judge voluntarily that present communication modes is wireless network or cable network, and the decision output form, above-mentioned formative digit audio-visual Datagram is converted into the digit audio-visual Datagram that meets the 3G system specification, maybe this formative digit audio-visual Datagram is converted into the digit audio-visual Datagram that meets the MPEG specification; One wireless output device is the purpose terminal that the digit audio-visual Datagram of the above-mentioned 3G of the meeting system specification is exported to the audiovisual materials platform; One wired output device is the purpose terminal that the digit audio-visual Datagram of the above-mentioned MPEG of meeting specification is exported to the audiovisual materials platform.
As above-mentioned system, the sender just can be with the first communication frequency that detects via auto-control software of audiovisual materials to determine the compact model and the transmission rate of institute's transmitting audio-video data by transmitting device, again via compression and numerical digit conversion process, be sent to purpose terminal rapidly to the audiovisual materials platform, make the recipient only need set a receiving system, just can do instant reception, broadcast.
