Description

一种移动通信终端电视信息传输系统及其实现方法 A communication system of the mobile terminal television information transmission and implementation method

[技术领域]本发明涉及移动数字电视广播与移动通信技术,特别涉及一种为移动通信终端电视用户传输互动式视频、音频和数据业务等的移动通信终端电视信息传输系统及其实现方法。 [Technical Field] The present invention relates to a mobile digital television broadcasting and mobile communication technologies, and particularly relates to a mobile communication system for transmitting television information terminal to transmit a mobile communication terminal user interactive TV video, audio and data services and implementation.

[背景技术]从目前来看,在移动通信终端(如手机)上播放的电视内容属于广播电视网络,移动通信终端属于移动通信网络,要解决在移动终端上实时播放电视信息的主要难题是传输网络。 [Background] now, TV content to play on the mobile communication terminals (such as mobile phones) belongs to the broadcast television networks, mobile communication terminals belonging to the mobile communications network, to solve the main problem of real-time broadcast television information is transmitted on the mobile terminal The internet. 目前还没有解决上述问题的完整的技术方案。 There is no complete technological solution to the above problems.

广播电视服务属于单向广播方式。 Radio and television broadcasting services are one-way. 基于单向广播方式的又分为基于地面的和基于卫星的两类。 It is divided into two categories based on ground-based and satellite-based one-way broadcast mode. 目前基于卫星的主要有韩国S-DMB(数字媒体广播)、欧洲S-DMB;基于地面的技术主要包括欧洲DVB-T(地面数字视频广播)、DVB-H(手持数字视频广播)、韩国T-DMB、高通MediaFLO(请补充中文名称)、日本ISDB-T(综合业务数字广播)和清华DMB-T、上海交大ADTB-T(高级数字电视广播)。 The current satellite-based mainly Korean S-DMB (Digital Media Broadcasting), the European S-DMB; ground-based technologies include the European DVB-T (Digital Video Broadcasting Terrestrial), DVB-H (Digital Video Broadcast Handheld), South Korea T -DMB, Qualcomm MediaFLO (please add Chinese name), the Japanese ISDB-T (integrated services digital broadcasting) and Tsinghua University DMB-T, Shanghai Jiao Tong University ADTB-T (advanced digital television broadcasting). 基于卫星的方式跨区域性、移动性都很好,但门槛高、代价大、频谱利用率低,不便于选择运营规模;基于地面的方式带宽大、组网规模灵活、代价小。 Cross-way satellite-based regional mobility are good, but the high threshold, high costs, low utilization of spectrum is not easy to select the scale of operations; ground-based way bandwidth, flexible networking scale, small price.

基于地面的方式中,高通MediaFLO在频道区分上采用特有的帧格式和复用技术,这显然使得前端设备不具有通用性;清华DMB-T、上海交大ADTB-T和日本ISDB-T都没有考虑到节电问题,势必影响到移动通信终端的使用,另外,它们的频道区分单一采用MPEG-2 TS,对于手机等移动通信终端来说,内容所占的码率太大会影响下载时间。 Ground-based manner, Qualcomm MediaFLO using the unique frame format and channel multiplexing on the distinction, which obviously makes the front-end device does not have the versatility; Tsinghua DMB-T, Shanghai Jiaotong ADTB-T and ISDB-T Japan did not consider to energy-saving issues, will inevitably affect the use of mobile communication terminals. in addition, they distinguish between a single channel using MPEG-2 TS, for mobile phones and other mobile communication terminal, the content rate too much effect on the share of the download time. 相对来说,欧洲DVB-H和韩国T-DMB比较适合于手机等移动通信终端。 Relatively speaking, the European DVB-H and T-DMB of Korea is more suitable for mobile phones and other mobile communication terminals. 其中,在带宽方面,DVB-H有较好的频率差异性,即平坦部分衰减的概率较小;在内调制方面,在高斯通道,DVB-H QPSK比T-DMB D-QPSK有3dB的好处;在错误编码方面,DVB-H总共有5-6dB的好处;在支持速率方面,DVB-H提供更大的容量和更大的弹性;在灵活性方面,DVB-H提供多种可能性,所以DVB-H能够保障将来业务的增长;在时分复用系统方面,DVB-H使用实际的时间切片,T-DMB使用微时间切片,所以在节电方面,DVB-H更优秀;在协议stack方面,DVB-H有更大的灵活,能够适应将来业务发展的需要。 Wherein, in terms of bandwidth, DVB-H has a better frequency difference, i.e. the smaller the probability of the flat portion of the attenuation; including modulation aspect, in the Gaussian channel, DVB-H has the QPSK benefits than 3dB T-DMB D-QPSK ; in terms of coding errors, DVB-H 5-6dB of total benefits; support in terms of rate, DVB-H provides greater capacity and greater flexibility; in terms of flexibility, DVB-H offers a variety of possibilities, so DVB-H can ensure the future growth of the business; in the time division multiplexing systems, DVB-H uses the actual time slices, T-DMB using micro time slices, so in terms of energy-saving, DVB-H better; the protocol stack respect, DVB-H have more flexible and able to adapt to future business development. 因此,欧洲DVB-H适合于作为移动通信终端等手持式移动数字电视的传输技术标准。 Therefore, the European DVB-H standard transmission technique suitable as a handheld mobile digital TV mobile communication terminal or the like.

现有的移动通信网络主要是2G,2.5G,3G。 Existing mobile communication networks are mainly 2G, 2.5G, 3G. 2G包括GSM(全球移动通信系统)、TDMA(时分多址)。 Including 2G GSM (Global System for Mobile Communications), TDMA (Time Division Multiple Access). 中国移动、中国联通都是采用GSM,它的码率只有9.6Kbps。 China Mobile, China Unicom and are based on GSM, its rate only 9.6Kbps. 2.5G主要包括GPRS(通用分组无线业务)、CDMA2000 1x(码分多址)。 2.5G include GPRS (General Packet Radio Service), CDMA2000 1x (Code Division Multiple Access). 中国移动采用GPRS,中国联通采用CDMA2000 1x。 China Mobile uses GPRS, China Unicom uses CDMA2000 1x. 它们的码率只有56Kbps,而实际上只能稳定在40Kbps。 Their rate is only 56Kbps, while really only stabilized at 40Kbps. 可以运行于GPRS、CDMA2000 1x之上的2.5G技术还包括WAP(无线应用协议)、EDGE(增强数据速率的GSM演进)、HSCSD(高速电路交换数据服务)和EPOC(Electronic Piece Of Cheese)等。 Can run on GPRS, 2.5G technology CDMA2000 1x above further includes WAP (Wireless Application Protocol), EDGE (Enhanced Data rates for GSM Evolution), HSCSD (High Speed ​​Circuit Switched Data) and EPOC (Electronic Piece Of Cheese) and the like. 据说这些技术理论上可提供高于56Kbps的码率。 It is said that these techniques can theoretically provide a higher rate of 56Kbps. 其中,GPRS是通过GSM升级过来,只需软件升级和添加相关的板卡。 Which, GPRS through GSM upgrade over just a software upgrade and add the relevant board. 3G包括W-CDMA,CDMA2000 3x和TD-SCDMA。 3G includes W-CDMA, CDMA2000 3x, and TD-SCDMA. W-CDMA是从GSM发展而来,是欧洲技术;CDMA2000 3x是从CDMA2000 1x发展而来,是美国高通公司技术;TD-SCDMA是中国大唐技术,拥有自主知识产权。 W-CDMA evolved from GSM, a European technology; CDMA2000 3x evolved from CDMA2000 1x is a Qualcomm technology; TD-SCDMA is China Datang technology with independent intellectual property rights. 3G理论上可以提高码率到64Kbps×3~7;软合并64Kbps×10~17(~1Mbps)/5MHz,但目前的实际试验情况来看,还只能达到100~300Kbps。 3G is theoretically possible to increase the rate 64Kbps × 3 ~ 7; soft combining 64Kbps × 10 ~ 17 (~ 1Mbps) / 5MHz, but the actual test situation, but also only reach 100 ~ 300Kbps.

下面将DVB-H与3G进行简单的比较:从带宽来看,DVB-H是属于地面广播电视标准,支持带宽很大,可以支持大业务量;3G从目前的实际试验情况来看,只能达到100~300Kbps。 The following will be a simple comparison of DVB-H and 3G: From the bandwidth point of view, DVB-H is a terrestrial broadcast television standards belong to, support large bandwidth, can support a large volume of business; 3G from the current actual test situation, only reaches 100 ~ 300Kbps. 移动通信网络主要缺点是带宽窄、业务量小。 The main drawback is the mobile communication network bandwidth is narrow, a small amount of traffic. 从互动性来看,DVB-H是属于单向广播,缺少手机电视用户所需要的个性化、互动性;3G是完全双向,可灵活实现个性化与互动性。 From the interactive point of view, DVB-H is part of a one-way radio, mobile TV users lack the required personalization, interactivity; 3G is fully bidirectional, flexible and personalized interactivity. 从计费方式来看,DVB-H计费方式不灵活,只能采用广播方式的CAS系统,实施前端加密、终端认证的方式,导致计费方式只能是包月,或者内容不加密,免费收看,通过插播广告,收取上游厂家的广告费用;3G计费方式灵活,可以支持按时计费、按流量计费和按片付费、包月等。 From the point of view charging mode, DVB-H is not flexible billing methods, only using the CAS system broadcast, encryption distal embodiment, the terminal authentication way, resulting in only a monthly accounting mode, or the content is not encrypted, free to watch by commercials, upstream manufacturers charge advertising costs; 3G billing flexible and can support time and billing, pay-per-piece by traffic and billing, monthly and so on. 从建设网络成本来看,DVB-H网络建设成本小,一个城市也就在2000万元以内;3G网络建设成本大,不像2G升级到2.5G,只需要升级软件和添加一些板卡,3G,尤其是TD-SCDMA是一张全新的网络,需要重新建设网络,一个城市的建设费用在5个亿左右,国内要完成建设好一张3G网络,也需要1~2年的时间。 The cost of building from the network point of view, DVB-H network construction cost is small, there is a city in less than 20 million yuan; large 3G network construction costs, unlike 2G upgrade to 2.5G, only need to upgrade software and add some cards, 3G especially TD-SCDMA is a new network, we need to re-build the network, the cost of building a city of about 5 million to complete the domestic build a 3G network, it takes 1 to 2 years. 从终端成本来看,DVB-H终端成本不高,只需要在现有中高档手机的基础上,添加一个5美元左右的芯片就可以,价格估计在3000~5000元左右;3G的终端成本相当高,需要使用多个时隙,估计价格在7000~10000元左右。 From the viewpoint of cost terminal, DVB-H terminal cost is not high, only the high-end mobile phones based on the prior addition of about a $ 5 chip can, the price is estimated at around 3,000 to 5,000 yuan; 3G terminal cost is quite high, requires the use of a plurality of slots, the price is estimated in 7000 to 10,000 yuan. 从用户费用来看,DVB-H带宽成本低,只需要向用户收取内容收视费就可以了;3G带宽成本高,不仅要向用户收取内容收视费,还要向用户收取带宽占用费(服务费)。 From the point of view of user fees, DVB-H low bandwidth cost, users only need to charge subscription content on it; 3G bandwidth, high cost, not only content subscription fees charged to a user, but also charge fees bandwidth to the user (service fee ). 根据目前的分析来看,带宽占用费可能远远超过内容收视费。 According to the current analysis, bandwidth usage fees may be far more than content subscription fees. 使得与DVB-H相比,在收看相同内容节目的前提下,3G用户要付出更多的费用,以至于没有多少用户能够消费得起。 So that compared to DVB-H, on the premise of watching the same program content, 3G users to pay more money, so not many users can afford.

通过上术对DVB-H和3G的比较,可以得出:虽然移动通信终端电视市场巨大,但目前这两种最优秀的传输网络,由于各自存在的一系列问题,都严重地制约了移动通信终端电视的正常发展。 By comparing the operation of DVB-H and 3G can be drawn: Although huge mobile communication terminal TV market, but the two most outstanding transmission network, due to the presence of the respective series of problems have seriously restricted the mobile communications the normal development of the terminal TV.

DVB-H地面广播网络2以单频网络4k模式为组网优选方案。 DVB-H terrestrial broadcast network 2 to 4k mode is a single frequency network networking preferred embodiment. 当然,也可以采用多频网,或者单频/多频混合网络实现。 Of course, multi-frequency network may be used, or a single-band / multi-frequency hybrid networks. 但是多频网络频谱利用率很低,而单频网特别适合于现代城市高楼林立、参差不齐,以至于需要建立较多基站的情况。 But the multi-frequency network spectral efficiency is very low, while the single-frequency network is particularly suitable for the modern city of skyscrapers, uneven, so that the situation needs to establish more base stations.

在DVB-H系统中,可以采用8k、4k、2k模式。 In the DVB-H system may be employed 8k, 4k, 2k mode. 上述模式本身并不影响码率,模式只影响移动特性和发射塔间距。 Said mode itself does not affect rate, and mobility characteristics affect only mode towers spacing. 如8k模式在8MHz(实际为7.61MHz)的频带上分布着6817个载波,每个载波间的间距为1.116KHz,而2k模式只分布1705个载波,每个载波间的间距为4.464KHz,所以2k模式的移动特性比8k模式的好(运动产生多普勒频率效应,速度越快,多普勒频率效应越厉害)。 As 8k mode 8MHz distribution (actually 7.61 MHz) frequency band 6817 with carrier spacing between each carrier is 1.116KHz, 2k mode and distributed only 1705 carriers, the pitch between each carrier is 4.464KHz, so the 2k mode mobility characteristics better than the 8k mode (motion Doppler frequency effects, faster, more powerful Doppler frequency effect). 而2k模式相对应于8k模式的保护间隔小,所以基站就要布得密。 The 2k mode and the 8k mode corresponds to the protection interval is small, the base station must fabric more densely. 所以选择4k模式可以兼顾移动特性和基站半径大小。 4k mode can be selected so that both the base station and the radius of mobility characteristics. 在实际使用中,可以根据情况选择2K或8K模式。 In actual use, 2K or 8K mode can be selected according to the situation.

DVB-H所需基站较少,一个城市一般不超过10个,而2G/2.5G所需基站较多。 The base station is less desired DVB-H, a city is generally not more than 10, the 2G / 2.5G more desired base station. DVB-H可以共用2G/2.5G基站的一些资源,如发射塔、配电216、监控217等,只需通过传输分配网路22把数据送到2G/2.5G基站,在该基站安装发射机、拉馈线和合路器等就可以了。 DVB-H can share 2G / 2.5G some resources of the base station, such as towers, power distribution 216, monitor 217, etc., by simply transmitting data to the distribution network 22 2G / 2.5G base station, which is mounted in the transmitter , pull the feeder and combiners, etc. on it.
