  • the broadcast video stream can be transmitted over a surface or satellite-based RF transmission system, or broadcast over a cable television line that is widely distributed between the transmitter and the client.
  • packet switching is a method of communication.
  • the packet exchange is to cut the data into a segment of the packet before sending, and then the sender signs the address of the receiver in each packet and transmits it to the network. After receiving the packet, the receiver combines the packets. When the packet is in transit, it will be slightly stopped at the passing node. After the node receives the complete packet, it will transmit to the next node. Packet exchange can provide information transmission from multiple sources at the same time. Each packet can find the best path according to the situation, and then reorganize the original information after reaching the destination.
  • the advantage of the packet exchange method is that the throughput rate is high, the time delay is small, and no data is retransmitted when an error occurs.
  • IPTV Internet Protocol Television

  • One-hour IPTV requires 5 gigabytes of capacity, which is equivalent to 1,000 hours of voice, which is greater than the total capacity of a network user to send and receive mail throughout the year.
  • IPTV customers With the rapid increase of the end, the required bandwidth will also increase rapidly, and this trend will bring huge challenges to the transmission load of the network.
  • Program content can be spread by unicast technology. Whenever a new connected user is added to the IPTV system, the server must provide the bandwidth required to transmit the content requested by the new user. Therefore, the IPTV system using unicast technology needs to be compared when serving more users. The large bandwidth makes it costly for a single service person. Although IPTV systems using unicast technology are limited by the maximum number of simultaneous services and their service costs, in the era of personalized services, VOD (Video-On-Demand) services that provide personalized needs are The most important advantage.

Description

互动式服务系统、 互动式系统及其互动方法 技术领域
本发明关于网络互动式技术, 且特别关于一种互动式服务系统、 互动式系统及其互动 方法。 背景技术
广播电视系统已存在许久。在广播电视系统中,电视台提供广播视频流给众多的用户。 广播视频流可利用在地表上或以卫星为主的射频传输系统传送, 或者利用广布在发送端 (transmitter)与客户端间的有线电视线路进行广播。
在计算机网络和通讯中, 封包交换 (packet switching)是一种通讯方法。 封包交换是在 发送前将数据切割成一段段的封包, 然后发送端在每个封包内标注接收端的地址后, 将其 传送到网络上, 最后接收端接收完封包后, 将封包组合起来。 封包在传输途中, 会稍微停 留在经过的节点, 等节点收到完整封包 (packet)后, 再会往下一个节点传送。 封包交换可 同时提供多个来源的信息传输, 每个封包可视情况各自寻找最佳的路径, 到达目的地的 后再重组原始的信息。 封包交换方法的优点是吞吐率高, 时间延迟较少, 发生错误时也不 需重送全部的数据。
最近, 随着高速封包交换网络的技术的进步, 网络电视 (Internet Protocol Television; IPTV)因此孕育而生。在 IPTV系统中, 视频、音频和数据信号是使用互联网络分配给客户 端。 IPTV通常通过 DSL或光纤到户 (FTTH)网络来提供, 并由拥有网络的厂商业者 (通常 是当地的电话公司)提供服务。 以一个最小型的 IPTV系统为例来说明, IPTV系统只需要 三个网络单元: 将广播电视转换成 IP数据封包的编码器、 将客户端连接到服务供应商的 网络, 以及一个位于客户端所在且将 IP数据封包转换成视频的视频转换盒。 典型的网络 还包括几个辅助系统: VOD 服务器、 广告插播系统、 计费平台和数字版权管理 (DRM)系 统。
IPTV系统利用连接到客户端的网络提供所有的信息通道, 包括广播信息通道和 VOD 信息通道。 IPTV 系统的所以可行是因为利用先进的视频编解码, 大幅提高压缩比所致, 其所利用的视频编解码为 MPEG-4 (H.264)编解码技术, 压缩比可大于 100:1。 即便如此, IPTV还是迄今为止网络中占用频宽最高的服务。 一小时的 IPTV就需要 5G字节的容量, 与 1,000小时的语音相当, 大于一个网络使用者全年收发邮件的总容量。 随着 IPTV客户 端的快速增加, 所需的频宽也随之迅速增加, 而此趋势将为网络的传输负荷带来巨大的挑 战。
节目内容可以单点传播 (unicast)技术传播。每当 IPTV系统新增一位连线使用者,服务 器必须提供传送新增使用者要求的内容所需的频宽,因此使用单点传播技术的 IPTV系统, 当服务较多使用者时, 需较大的频宽, 从而使其单一服务人数的成本高。 虽使用单点传播 技术的 IPTV系统受限于最大同时服务的人数及其服务成本; 但在强调个人化服务的时代 里, 能够提供个人化需求的 VOD(Video-On-Demand)服务, 是其最重要的优点。
为能同时服务多位客户端, IPTV系统业者多会采用多点传输技术 (multicast), 来传送 节目内容。 多点传输是通过网络通讯协议中 Class D 的 IP所负责, 即 IP地址由 224.0.0.0 到 239.255.255.255的间的所有 IP。经由 Class D传送串流数据的媒体服务器, 会将单一串 流处理传给多个客户端, 而这些客户端无需与此媒体服务器做连线。 既然是以广播的方式 传送内容, 就难以同时提供 VOD服务, 因客户端与服务器可能无连线, 两者间无互动性。
在 IPTV系统中, 游戏节目是一种常见的节目型态。 在游戏节目 (game show)中, 远端 参赛者会争先恐后地回答问题, 以赢得奖金。 游戏节目是以互动 (interactive)方式进行, 参 赛者将答案输入视频转换盒。 之后, 电视上显示答案传送至游戏服务器储存的确认提示。 游戏服务器储存每一参赛者回答问题的答案, 并据此判断最后的胜出者。倘若参赛者输入 正确的答案, 却因为游戏服务器与视频转换盒间网络传输问题或传输延迟, 导致答案无法 储存或延迟储存在游戏服务器中, 造成参赛者丧失取得优胜的资格。 前述的状况, 特别容 易发生在当过多的用户使用 IPTV系统时。若前述的状况真的发生,恐将产生抗议或申诉, 造成游戏节目业者的信誉或金钱的损失。 发明内容

在叠加引擎 137内, 图形元件被叠加至来自视频串流解码器 135的影像数据。合成影 像数据接着被处理器 132提供, 经由显示界面 133而显示在显示荧幕 14上, 以供使用者 观看。
终端装置 13可利用遥控器 25操作。 遥控界面 134接收使用者按遥控器 25所产生的 选择结果。 选择结果传送至处理器 132, 处理器 132将该选择结果转换成网络传输的标准 编码格式、 封装 (encapsulate)成适合的数据格式 (如封包)、 赋予一优先等级, 以及经由网络 界面 131传送至数据机 12。
图 7显示本发明一实施例的影像与响应数据的叠加方法。参照图 7所示, 视频串流被 解码后, 在荧幕上显示影像 71。 影像 71中可包含节目主持人 72。 互动式系统 1提供选择 选项, 选择选项叠加在影像 71上。 在本实施例中, 问题 73(例如: 秘鲁首都在哪?)放置在 主持人 72上方。在影像 71的右下角可显示回答问题的所剩时间 74。在本实施例中, 框内 显示 12秒。在影像 71下方提供一表格 75, 表格 75为 2乘 2格式。表格 75中记载选择选 项, 其分别是" Lima"、 "Lama"、 "Laos"和" Liechtenstein"。
影像 76系图形元件 24的一范例。 参加人的个人相关数据显示在影像 76上, 例如: 参加人的姓名 ("王小明")和平均分数 ("6")。 再者, 参加人因已经选择表格 75 左上角 的" Lima", 因此粗框 77被提供, 以向参加人确认其所作的选择。
终端装置 13将影像 71与影像 76叠加, 以获得一显示画面 78。在显示画面 78上, 粗 框 77叠放在 "Lima"上, 以显示参加人的选择。 再者, 参加人的个人相关数据也可见于显 示画面 78上。
本实施例中虽以粗框 77 向参加人确认其所作的选择, 但本发明不以此为限。 其他能 区别选择与非选择的方法, 也可运用在本发明的实施例中。 特而言的, 使用者能在视频串流的影像上看到自己的相关数据和自己的选择答案, 其 他不同的使用者在相同的视频串流的影像上看到不同的数据和答案。未登录的使用者则仅 能看见视频串流的影像。
图 8显示本发明一实施例的数据机的硬件结构示意图。 参照图 8所示, 数据机 12包 含一处理器 121、一总线 122 易失性存储器 123、一非易失性存储器 124和一网络接口 36。 处理器 121、 易失性存储器 123、 非易失性存储器 124和网络接口 36耦接总线 122 数据机 12另包含其运作所需的应用程序和操作系统。 应用程序和操作系统储存于非易失 性存储器 124内。 当数据机 12启动后, 应用程序和操作系统装载到易失性存储器 123。 网 络接口 36可连接局域网 18或广域网 16
图 9显示本发明一实施例的数据机的功能方块图。本发明揭示的互动式系统 1可确保 使用者所选择的答案可快速地储存在媒体串流服务器 111上, 并显示在荧幕上, 让使用者 确认其所选择的答案已被接受, 避免造成不必要的困扰。 为此, 在互动式系统 1中, 网络 流量被分级控管。 使用者所选择的答案会被优先传送至媒体串流服务器 111, 如此使用者 可很快地知道他选择的答案被接收, 而避免选择答案传送延迟, 甚至未被媒体串流服务器 111所接收到。互动式系统 1的网络流量控管可采用许多的方法 (协议),例如: ToS(Type of Service)协议、 QoS(Quality of Service) 802.1Q和 802.1p或其他类似者。
在一实施例中, 终端装置 13将使用者选择的答案封装成帧 (frame), 并标示以最高优 先等级的标签, 使所述多个帧可被优先传送。
在一实施例中, 互动式系统 1的网络流量控管也可根据帧的 IP precedence值, 来决定 帧传送的优先性。
参照图 9所示, 数据机 12包含一缓冲器 125、 分类单元 126、 第一队列〜第三队列和 读取控制单元 127。 缓冲器 125耦接终端装置 13, 以暂时储存来自终端装置 13的封包或 帧。 分类单元 126耦接缓冲器 125与第一队列〜第三队列, 以按封包或帧的优先等级放入 相应的队列 1 3。 在数据机 12 中, 提供低优先等级的第一队列、 中优先等级的第二队列 和高优先等级的第三队列, 然此仅为例示, 本发明不限于此。 第一队列〜第三队列耦接一 读取控制单元, 其依序将为于第一队列〜第三队列内的封包或帧取出, 并传送至互联网络 在本实施例中, 数据机 12的上行传输分成 3种优先等级, 而下行传输则未区分优先 等级, 但本发明不以此实施例为限。
以下枚举数例, 还详细说明本发明互动式系统 1的网络流量控管的方法。 在一实施例中,在上行传输方向上,优先权代码为 5(802. lp=5)的帧会被分类在高优先 等级的第三队列中。优先权代码为 3(802.1p=5)的帧会被分类在优先等级为中等的第二队列 中。 优先权代码为 0、 1、 2、 4、 6、 7(802.1ρ=0 1、 2、 4、 6、 7)的帧会被分类在优先等级 为最低的第一队列中。 未被标签的帧 (Untagged frames)中, IP precedence值为 5者会被分 类在高优先等级的第三队列中; IP precedence值为 3者会被分类在优先等级为中等的第二 队列中; 而 IP precedence值为 0、 1、 2、 4、 6、 7则被分类在优先等级为最低的第一队列中。
在另一实施例中,帧被转换成 (convert)具虚拟网络辨识码 (VLAN Identifier; VID)的帧。 帧中的 IP precedence值会被写入 802.1p栏内。 IP precedence值为 5的帧会被分类在优先等 级高的第三队列中; IP precedence值为 3的帧会被分类在优先等级为中等的第二队列中; 而 IP precedence值为 0、 1、 2、 4、 6、 7的帧则被分类在优先等级为最低的第一队列中。
在上行方向上, 优先权代码为 5(802.1p=5)的帧会被分类在高优先等级的第三队列中。 优先权代码为 3(802.1p=5)的帧会被分类在优先等级为中等的第二队列中。优先权代码为 0、 1、 2、 4、 6、 7(802.1p=0 1、 2、 4、 6、 7)的帧会被分类在优先等级为最低的第一队列中。
图 10显示本发明另一实施例的互动式系统 2的示意图。参照图 10所示,终端装置 13a 经由数据机 12连接互联网络,而服务系统 11通过互联网络提供一服务内容于终端装置 13a 和无线终端装置 13b, 而终端装置 13a和无线终端装置 13b的显示器显示服务内容于使用 者。服务内容以视频串流传送,其可为民意调查或拍卖服务等。服务内容包含选择选项 140。 终端装置 13a可包含一触控荧幕 138, 使用者可利用触控荧幕 138, 选择所欲的选择选项 140。 终端装置 13a将选择结果设定为最高优先等级来传送。 数据机 12可根据不同的优先 等级传送数据。 服务系统 11接收选择结果后, 储存选择结果, 并根据该选择结果, 产生 响应数据。 在一实施例中, 服务系统 11可以赋予响应数据一最高优先等级, 而使响应数 据尽快被传送至终端装置 13a。在另一实施例中,服务系统 11可以单播方式将响应数据传 送至终端装置 13a。 终端装置 13a接到响应数据后, 在被选择的选择项目上做标记, 让使 用者可确认其选择被服务系统 11所接受。 选择结果以最高优先等级来传送和响应数据快 速地传回终端装置 13a, 使得服务系统 11与使用者的间的互动可近似即时的方式进行。
本发明的技术内容及技术特点已揭示如上,然而本发明所属技术领域中具有通常知识 者应了解, 在不背离后附申请专利范围所界定的本发明精神和范围内, 本发明的教示及揭 示可作种种的替换及修饰。例如,上文揭示的许多不同的方法实施或以其它系统予以取代, 或者采用上述二种方式的组合。因此,以下的申请专利范围涵盖此类等同的系统及方法步骤。
