Description

一种远程一见频访问系统及方法技术领域本发明涉及移动电视技术,具体指一种通过移动终端实现远程视频访问的系统及方法。 A remote access system and a frequency see TECHNICAL FIELD The present invention relates to mobile TV technology, specifically refers to a system and method for remote video access is achieved by a mobile terminal. 背景技术随着无线通信技术、音频和视频编码技术、以及大规模集成电路技术的快速发展,用户不再满足于局限于固定终端收看电视节目,而是希望能在自由移动的过程中,随时随地收看到自己喜欢的节目移动终端电视业务的使用已经比较普遍,所谓移动终端电视业务是指通过移动终端收看电视节目的服务。 BACKGROUND With the rapid development of wireless communication technology, audio and video coding technology, and large-scale integrated circuit technology, users are no longer limited to a fixed terminal to meet to watch TV, but to be able to move freely in the process, anytime, anywhere to watch their favorite programs using a mobile terminal TV service has become popular, so-called mobile terminal TV service refers to watch TV programs through mobile terminal services. 目前,广播技术的发展已经实现了通过广播电视网络,以广播的方式将电视节目发送到移动终端上,来实现用户无论是在户内户外、本地异地,均可收看到电视节目。 At present, the development of radio technology has been achieved, by broadcasting a television program will be sent to the mobile terminal through radio and television network, to achieve the user both in indoor and outdoor, local off-site, can watch TV programs. 虽然通过广播方式有其上述优点,但同时存在以下缺点:首先,通过广播方式发送电碎见节目,虽然可进行加密,但密钥只能以群发的方式发送,而无法定向发送;因此,即使仅有一个用户选择收看某一套节目,广播电视网络也必须向覆盖区域内所有的用户终端发放密钥,造成不必要的系统资源和网络带宽浪费,也带来了密钥破解几率的增加,不利于保证运营商的业务安全,也不利于对用户资格进行有效认证;其次,通过广播方式发送电视节目时,广播电视网络无从得知终端是否收到该电视节目,为了保证成功接收,只能反复不断的发送,带来了系统的巨大负荷和浪费,另外,通过广播方式发送电视节目是单向发送,用户无法进行反馈,因此只能被动接受,而不能实现主动参与。 Although there are broadcast by its aforementioned advantages, the following drawbacks at the same time: first, the broadcast transmitting electrically broken by the program to see, although may be encrypted, but the keys can only be transmitted in a bulk manner, the orientation can not be transmitted; Thus, even only one user chooses to watch a set of programs, broadcast television networks also have key issued to all user terminals within the coverage area, resulting in unnecessary waste of system resources and network bandwidth, it also brings increased the chances of cracking the key, It is not conducive to guarantee the security of business operators, is not conducive to the effective user eligibility certification; secondly, by sending broadcast television programs, radio and television network is not known whether the terminal receives the television program, in order to ensure successful reception only repeated constantly sending enormous load and waste systems. in addition, transmission of television programs broadcast by way of sending a one-way, users can not feedback, and therefore are forced to accept, but can not achieve active participation. 在广播电视网络之外,目前移动通信网络中也实现了发送电视节目到终端的技术:由SP/CP制作节目源,或者从广播电视网络获取节目源,通过移动网络发送给移动终端。 In addition to television broadcast network, the mobile communication network also transmits television program to realize the technology of the terminal: or acquired from a broadcast television program source network of SP / CP production program source, to the mobile terminal through the mobile network. 这种方式能够实现定向发送节目以及进行用户交互,但同时却也存在以下缺点:第一,移动通信网络所提供的带宽不足,所以用户的收看效果无法得到保证;第二,SP/CP的网络带宽和服务器资源受到用户数量的限制,因此,如果5同时收看的用户较多或者遭到网络拥塞,则用户的收看效果无法得到保证。 This approach can achieve directional transmission program and user interaction, but it also has the following disadvantages: First, the mobile communication network is insufficient bandwidth available, the user's viewing effect can not be guaranteed; second, SP / CP network bandwidth and server resources by limiting the number of users, so if 5 or more users while watching the network was congested, then watch the effect the user can not be guaranteed.

another example is when a program C and D as the number of times of the main window are displayed as 6, length up to 2 hours preview program propan the length up to 6 hours to preview the program D, the next to the selected program propionate, and then the selected program butoxy when, due to the preview program butoxy main window accumulated grow up to the program C, then automatically the program butoxy displayed in the main window; may be set to occur previewed reached or a certain cumulative duration (e.g., program pentyl small window widget cumulative preview time length up to 10 hours) or display a certain number of frequencies (e.g., pent-preview program to the accumulated number of widget 30 times 后下一次预览时自动将其在主窗口显示。 Automatically displayed in the main preview window after the next time. 所述移动终端13A/v移动网络的一个基站进入到另一个基站时,例如,移动终端13从本区基站A进入到外区基站B时,如果视频处理装置12与移动终端13 继续保持连接并传输音视频数据,则将产生漫游费用,此时移动终端13将向流媒体服务器12 3发送基站更换信息,流媒体服务器12 3接收到基站更换信息后向移动终端13发送提示信息,提示是否中断移动终端13与视频处理装置12间的无线连接。 When the mobile terminal 13A / v of a base station enters the mobile network to another base station, e.g., the mobile terminal 13 enters the area from the base station A to an outer region of the base station B, if the video processing apparatus 12 and the mobile terminal 13 and remain connected transmission of audio and video data, roaming charges will be generated, where the mobile terminal 123 the media server 13 will replace the base station transmits traffic, streaming media server 123 receives the information transmitted to the base station replacement prompt information to the mobile terminal 13, whether to interrupt the prompt the mobile terminal 13 is connected to the wireless video processing device 12. 所述反馈验证装置12 6 ,当视频发送装置124向移动终端13持续发送压缩编码后的语音、图像数据包信息时,进行阶段性反馈信息验证,将发送信息的过程自动划分为多个时间片段tl、 t2、 t3……,在每个时间片段(例如在tl时段) 结束时,自动生成一个发送数据统计包,该统计包中包括当前时间片段(例如在tl时段)已发送的数据包字节数S,并向移动终端13发送一个接受数据反馈指令,接受移动终端发来的数据反馈,该数据反馈包反馈移动终端13在tl时段接受的数据包字节数C,反馈验证装置对S减去C的差值Q进行分析,如果Q小于或等于设置的阈值范围,验证通过,继续下一片段(例如继续发送t2片段)数据的发送,如果Q大于设置的范围,进行一次数据发送异常记录,如果未收到字节数C,则暂停下一片段数据的发送,直到收到字节数C时恢复数据发送,如 The feedback verification means 126, the process when video transmitting apparatus 124 to the mobile terminal 13 continuously transmits the compressed speech encoded, the image data packet information, the feedback information is periodically verified, the information is automatically transmitted into a plurality of time segments tl, t2, t3 ......, at each time segment (e.g., in a period tl) at the end, to automatically generate a packet transmission statistics, statistical package which includes the current time slice (e.g. in the period tl) the transmitted data packet word number of sections S, and the mobile terminal 13 sends a command to accept feedback data, the mobile terminal receiving the data sent from the feedback, the feedback data packet returns the mobile terminal 13 received in the period tl number of bytes of packet C, verification means for feedback S subtracting the Q C difference analysis, if the range is less than or equal to the threshold value set Q, verified, proceed to next segment (e.g., segment continues to transmit t2) of the transmission data, if Q is greater than the set range, once the abnormal data transmission recording, if the received byte is not C, transmits the next segment of data is suspended until the number of bytes upon receipt of C recover the transmitted data, such as

果超过一定时间未收到字节数c,则终止本数据发送过程,本实施例中,例如假设tl时段的统计包S为200字节、反馈包C为100字节、差值Q为100字节,阈值范围为IOO,由于Q等于,则验证通过,继续发送t2时段的数据。 If the time has not received over a certain number of bytes C, the present data transmission process is terminated, in the present embodiment, for example, assumed that the statistical package period tl S is 200 bytes, 100 bytes feedback packet C, Q is the difference between 100 byte, the IOO threshold range, since Q is equal, the authentication is passed, continue sending data period t2.

对上述统计包的进一步改进,统计包还包括当前时间片段已发送的数据包数量S1及每个数据包编号,移动终端的反馈包中也包括移动终端接受到的当前时间片段已发送的数据包数量C 1及每个数据包编号,发送数据反馈验证装置将Sl减去Cl的差值Ql,及未收到的数据包编号序列表记录到异常发送数据记录中,所述的移动终端13的反馈包中还包括无法正常解压播放的数据包编号序列表,数据反馈验证装置将数据包编号序列表记录到异常发送数据记录中。 Further improvement of the above statistical package, the package further comprising a current statistical feedback packet number of packets sent in time segments S1 and each packet number, the mobile terminal also includes a current time segment data packets of the mobile terminal receives the transmitted C 1 and the number of each data packet number, authentication apparatus transmits feedback data is subtracted Cl Sl Ql, difference, and the received packet data is not recorded in the sequence Listing ID transmission abnormality data record, the mobile terminal 13 feedback can not extract the package further comprising a normal play data packet numbering sequence table, the data recording device verification feedback data packet transmission number sequence table abnormal data record.
