副载波广播系统及方法 Subcarrier broadcasting system and method

技术领域 FIELD

[0001] 本发明涉及一种广播系统及方法,特别是涉及一种副载波广播系统及方法。 [0001] The present invention relates to a broadcast system and method, particularly to a system and method for subcarrier broadcasts.

背景技术 Background technique

[0002] 车辆可说是目前最广为人们使用的交通工具,为了提高驾驶人员的方便性,目前的导航装置不仅可以指引方向,同时也可以显示发生于全国各地的路况信息。 [0002] vehicle can say is currently the most widely used transport people, in order to improve the convenience of the driver, the current navigation device not only can guide the direction, but can also occur in the display of traffic information around the country.

[0003] 以中国台湾而言,高速公路局现已提供全国高速公路各路段即时车速的免费服务,而交通部运输研究所同样亦有提供全国即时路况的服务。 [0003] In terms of China Taiwan, the Highways Agency is now available in each section of the national highway speed real-time free service, while the Ministry of Transportation same Institute also provides nationwide real-time traffic service. 上述路况均是通过各地调频广播频道(例如警察广播电台)的副载波(subcarrier)提供给终端使用者。 Above all road conditions is available to end users through local FM radio channel (eg police radio station) the subcarrier (subcarrier). 而根据国际标准组织(ISO)的定义,RDS(Radio Data System)的传输速率理论值为每秒I. lKbits,由于所传输的数据中包含有抗扰频或抗杂讯等的信息,再加上信号在空气中传播的自然衰减,实际上可用来传输数据的频宽会更小。 According to the definition of the International Standards Organization (ISO) is, RDS (Radio Data System) is the theoretical value of the transmission rate per I. lKbits, since the transmitted data contains information about the anti-noise or anti-scrambling and the like, plus natural attenuation to the signal propagating in the air, in fact, used to transmit the data bandwidth will be smaller.

[0004]目前路况广播方法由分布于各地的广播电台直接将来自高速公路局和交通部运输研究所的数据全数对外发送,而未做筛选。 [0004] The method of the current data traffic broadcast by the radio stations distributed throughout the Institute directly from the Highways Agency and the Ministry of Transportation sends out full, but not to do the screening. 如前所述,RDS传输速率非常低,即便是理论值亦仅有每秒I. lKbits,因此当遇到尖峰时刻时,往往导致广播电台的数据发射负担过高,使驾驶人员无法及时接收到对他而言较重要的路况。 As mentioned earlier, RDS transmission rate is very low, even the theoretical value is also just a sec I. lKbits, therefore when faced with rush hour, often resulting in data transmission radio station burden is too high, so that the driver can not be received in time for him, the more important traffic. 此外,RDS的频宽完全被未经筛选的路况所占据也导致业者无法进一步通过RDS传输对驾驶人员更有用的附加信息。 In addition, RDS bandwidth fully occupied unfiltered road also leads the industry can not be further transmitted by RDS additional information on the drivers more useful.

[0005] 因此,现有习知的技术具有导致广播电台的数据发射负担过高,以及导致业者无法进一步通过RDS传输对驾驶人员更加实用的附加信息等问题。 [0005] Therefore, the existing conventional techniques have led to the burden of data transmission radio station is too high, resulting in the industry and can not be further transmitted to the driver through the RDS is more useful additional information and other issues.

[0006] 由此可见,上述现有的副载波广播系统在结构与使用上,显然仍存在有不便与缺陷,而亟待加以进一步改进。 [0006] Thus, the conventional broadcasting system subcarriers in structure and use, there is clearly still problems and disadvantages, and the urgent need to be further improved. 为了解决上述存在的问题,相关厂商莫不费尽心思来谋求解决之道,但长久以来一直未见适用的设计被发展完成,而一般产品又没有适切结构能够解决上述问题,此显然是相关业者急欲解决的问题。 In order to solve the above problems, the firms did not dare to think hard and to seek a solution, but has long been seen to be applicable to the design of the development is complete, and general product and no relevance structure can solve the above problems, this is obviously related businesses anxious to solve the problem. 因此如何能创设一种新型的副载波广播系统及方法,实属当前重要研发课题的一,亦成为当前业界极需改进的目标。 So how can we create a new sub-carrier broadcast system and method, it is currently the subject of a significant research and development, it has become the current industry in dire need of improvement goals.
