下文中将结合附图对本发明的实施例进行详细说明。 需要说明的是， 在 不冲突的情况下， 本申请中的实施例及实施例中的特征可以相互任意组合。
参照图 1 , 提出本发明使用网络唤醒会议电视终端召开视频会议的方法 一实施例， 包括：
步骤 S 10、会议电视系统的 MCU发送网络唤醒包到至少一在指定 GK未 注册的会议电视终端；
图 2所示为本实施例的典型应用场景， 包括 MCU101、 GK102、 路由器 103和多个会议电视终端 109, MCU101、 GK102、 路由器 103均接入到以太 网中， 会议电视终端 109分别通过各自的路由器 103接入以太网中。 其中， MCU101具有网络唤醒功能以及相应的页面配置。 按照用户在页面上的配置 信息， 发送网络唤醒包到需要参会的会议电视终端 109所在的子网， 借助会 议电视终端 109所属路由器 103进行广播， 最终唤醒会议电视终端 109。 所 述 GK102分别接受 MCU101和会议电视终端 109的注册，对在其上注册的资 源进行管理。 所述会议电视终端 109, 根据布局需求分布在各个会场之中， 在接收到路由器 103所广播的网络唤醒包之后， 对网络唤醒包进行解析， 如 果其中携带了与自身网卡相同的 MAC地址时，在相应 pin脚上产生使能会议 电视终端 109的电源模块的信号， 触发会议电视终端 109上电启动。 上述路 由器 103除了通常的路由功能之外， 其必须配置为转发定向子网广播包的功 能， 可以在子网中广播网络唤醒包， 以唤醒该子网中的会议电视终端 109。 当要召开视频会议时， MCU101查询参会的所有会议电视终端 109是否 已经在 GK102中注册， 如果是则开始视频会议， 如果否， 则启动网络唤醒功 能： 向所有需要参会， 但尚未在 GK102上注册的会议电视终端 109发送网络 唤醒包， 对于每一个参会的会议电视终端 109, 需要知道其 MAC地址、 IP 地址、 子网掩码等信息， 通过所属 IP地址和所属子网掩码， 可计算出需要发 送的网络唤醒包的目的子网广播地址， 通过所属 MAC地址构造出需要唤醒 的会议电视终端 109的网络唤醒包， 然后通过 raw socket编程把所构造的网 络唤醒包发送到需唤醒的会议电视终端 109所在子网。
步骤 Sl l、 所述至少一会议电视终端 109收到网络唤醒包后， 启动系统 并在 GK102上进行注册；
会议电视终端 109包括接收模块、 网络处理模块和主板电源管理模块， 接收模块即网络唤醒包进出会议电视终端 109的数据通道， 完成网络唤醒包 的接收，其通过 RJ45与外部网络连接，通过 ΜΠ或 PCI接口与会议电视终端 109的其它模块连接。网络处理模块包括一块具有 WAKE— ON— LAN功能的网 卡芯片 （例如 Realtek 8139C等）、 辅助电源及一些外围电路， 所述辅助电源 不依赖于主机电源， 可单独给所述网卡芯片供电。 所述网卡芯片可以在没有 CPU支持的前提下， 对经过网口的数据包进行解析， 根据数据包的 MAC地 址判断是否为唤醒本会议电视终端 109的网络唤醒包， 并在确认收到唤醒本 网卡的网络唤醒包的时候在一特定 pin 引脚上产生某特定的电平 （高电平、 低电平、 正向脉冲、 反向脉冲等） ， 以使能主板电源管理模块。 主板电源管 理模块， 是会议电视终端 109主板的电源供给管理模块， 其根据外部的一个 使能信号， 连上或切断主板的电源， 给会议电视终端 109上电或者断电。 以 Realtek 8139C 为例， 如果某会议电视终端 109 的网卡的 MAC 地址为 00:11:22:33:44:55 , 网 卡 在 网 口 上 检 测 到 了 FFFFFFFFFFFFOOl 122334455001122334455(重复 36 次本网卡 MAC 地址 001122334455),则说明这是属于唤醒本网卡的网络唤醒包，此时将在 LWAKE ( in83 )上产生一个高电平 （系统设计时根据系统需要配置） ， 从而使能主 板电源管理模块， 对会议电视终端 109上电。 会议电视终端 109启动系统， 并运行平稳后， 到 GK102上进行注册。
步骤 S12、 MCU在 GK上查询所述会议电视终端的注册信息；
MCU101在发送网络唤醒包后一指定时间如 10s , 向 GK102查询会议电 视终端 109是否已成功在 GK102上注册，延时一预设时间的目的是给会议电 视终端 109启动以及在 GK102上注册预留一定的时间。如查询到某一会议电 视终端 109的注册信息， 则表明该会议电视终端 109唤醒成功， 可将该会议 电视终端 109的状态信息标记为激活状态。
步骤 S13、 MCU根据所述注册信息决定是否召开视频会议。
MCU101根据查询的结果决定是否召开视频会议， 如所述需要参会的会 议电视终端 109都已经在 GK102上注册， 则召开会议。 或者当某一预设范围 内的会议电视终端 109已在 GK102上注册， 如某些重要的成员已经到齐， 而 部分非重要的成员缺席时， 也可召开会议。 决定是否召开会议可预先设置， 或者将会议电视终端 109的注册结果反馈给用户后， 由用户决定。
本实施例中， 可以在无须手动给会议电视终端 109上电开机的情况下召 开多点视频会议， 做到无须配置管理员会场支持便可预约会议召开。 相比于 目前在各地都需要配置一个会议电视管理员的做法， 可以大大地降低人员成 本， 提高了视频会议的效率。
在一实施例中， 步骤 S13包括：
当存在未在所述 GK102上注册的会议电视终端 109时， 返回步骤 S10。 当存在需要参会，但未在 GK102上注册的会议电视终端 109时， MCU101 重新发送网络唤醒包到上述未注册的会议电视终端 109, 然后经过所述预设 时间再查询 GK102是否存在之前未注册的会议电视终端 109的注册信息。 当 重发网络唤醒包的次数或查询注册信息的次数达一预设值时， 则放弃唤醒， 将无法唤醒的会议电视终端 109的状态信息标记为超时退出状态。 可以设置 一延时计数器， 对重发网络唤醒包的次数或查询注册信息的次数进行计数。 也可以设置一延时计时器， 当达到预设时间后， 则放弃唤醒。 上述方法可多 次唤醒会议电视终端 109, 又可防止陷入死循环。
参照图 3 , 提出本发明使用网络唤醒会议电视终端召开视频会议的方法 一实施例， 在上述实施例中， 还包括：
步骤 S14、 所述 MCU101根据用户的配置选择会议电视终端 109。
MCU101接收用户的配置页面关于召开会议的配置信息， 用户可以通过 配置页面选择需参会的会议电视终端 109, 选择立即开会或者预约会议。 本 实施例给用户提供根据实际需要进行选择的机会，使用户使用更加灵活方便。
参照图 4, 提出本发明会议电视系统的 MCU100—实施例， 包括： 发送模块 10 , 用于发送网络唤醒包到至少一在指定 GK未注册的会议电 视终端； 供所述至少一会议电视终端收到网络唤醒包后， 启动系统并在所述 GK上进行注册；
查询模块 20, 用于在所述 GK上查询所述会议电视终端的注册信息； 决定模块 30, 用于根据所述注册信息决定是否召开视频会议。
图 2所示为本实施例的典型应用场景， 包括 MCU100、 GK、 路由器和多 个会议电视终端， MCU100、 GK、 路由器均接入到以太网中， 会议电视终端 分别通过各自的路由器接入以太网中。 其中， MCU100具有网络唤醒功能以 及相应的页面配置。 按照用户在页面上的配置信息， 发送网络唤醒包到需要 参会的会议电视终端所在的子网， 借助会议电视终端所属路由器进行广播， 最终唤醒会议电视终端。所述 GK分别接受 MCU100和会议电视终端的注册， 对在其上注册的资源进行管理。 所述会议电视终端， 根据布局需求分布在各 个会场之中， 在接收到路由器所广播的网络唤醒包之后， 对网络唤醒包进行 解析， 如果其中携带了与自身网卡相同的 MAC地址时， 在相应 pin脚上产生 使能会议电视终端的电源模块的信号， 触发会议电视终端上电启动。 上述路 由器除了通常的路由功能之外， 其必须配置为转发定向子网广播包的功能， 可以在子网中广播网络唤醒包， 以唤醒该子网中的会议电视终端。
当要召开视频会议时， MCU100查询参会的所有会议电视终端是否已经 在 GK中注册， 如果是则开始视频会议， 否则启动网络唤醒功能： 发送模块 10向所有需要参会， 但尚未在 GK上注册的会议电视终端发送网络唤醒包， 对于每一个参会的会议电视终端， 需要知道其 MAC地址、 IP地址、 子网掩 码等信息， 通过所属 IP地址和所属子网掩码， 可计算出需要发送的网络唤醒 包的目的子网广播地址， 通过所属 MAC地址构造出需要唤醒的会议电视终 端的网络唤醒包， 然后通过 raw socket编程把所构造的网络唤醒包发送到需 唤醒的会议电视终端所在子网。
会议电视终端接收到网络唤醒包后， 自动上电并启动系统， 当会议电视 终端系统运行平稳后， 到 GK上进行注册。
查询模块 20在发送网络唤醒包后一指定时间如 10s , 向 GK查询会议电 视终端是否已成功在 GK上注册， 延时一指定时间的目的是给会议电视终端 启动以及在 GK上注册预留一定的时间。 如查询到某一会议电视终端的注册 信息， 则表明该会议电视终端唤醒成功， 可将该会议电视终端的状态信息标 记为激活状态。
决定模块 30根据查询的结果决定是否召开视频会议，如所述需要参会的 会议电视终端都已经在 GK上注册， 则召开会议。 或者当某一预设范围内的 会议电视终端已在 GK上注册， 如某些重要的成员已经到齐， 而部分非重要 的成员缺席时， 也可召开会议。 决定是否召开会议可预先设置， 或者将会议 电视终端的注册结果反馈给用户后， 由用户决定。
本实施例中， 可以在无须手动给会议电视终端上电开机的情况下召开多 点视频会议， 做到无须配置管理员会场支持便可预约会议召开。 相比于目前 在各地都需要配置一个会议电视管理员的做法， 可以大大地降低人员成本， 提高了视频会议的效率。
在一实施例中， 决定模块 30具体用于：
当存在未在所述 GK上注册的会议电视终端时，通过发送模块 10发送网 络唤醒包到至少一在所述 GK未注册的会议电视终端。
当存在需要参会， 但未在 GK上注册的会议电视终端时， 决定模块 30启 动发送模块 10重新发送网络唤醒包到上述未注册的会议电视终端，然后经过 所述预设时间再查询 GK是否存在之前未注册的会议电视终端的注册信息。 当重发网络唤醒包的次数或查询注册信息的次数达一预设值时 ,则放弃唤醒， 将无法唤醒的会议电视终端的状态信息标记为超时退出状态。 可以设置一延 时计数器， 对重发网络唤醒包的次数或查询注册信息的次数进行计数。 也可 以设置一延时计时器， 当达到预设时间后， 则放弃唤醒。 上述方法可多次唤 醒会议电视终端， 又可防止陷入死循环。
参照图 5, 提出本发明会议电视系统的 MCU100又一实施例， 在上述实 施例中， 还包括：
选择模块 40, 设置为根据用户的配置选择会议电视终端。
MCU100接收用户的配置页面关于召开会议的配置信息， 用户可以通过 配置页面选择需参会的会议电视终端， 选择立即开会或者预约会议。 本实施 例给用户提供根据实际需要进行选择的机会， 使用户使用更加灵活方便。
