细叙本发明图 1的工作原理:
图 1中, 计算机的显卡 13输出的 VGA信号在计算机接口模块 31的 PC 视频信号转换电路 311被转转换成 S-Video后, 再由 PC视频信号发送驱动电 路 312发送到通信线 32上。 计算机接口模块 31中的 PC端 USB驱动收发电 路 313负责接收来自计算机 USB接口 12的 USB第一信号加驱动后转发到通 信线 32上, 并接收通信线上的 USB第二信号并进行解调后转发给计算机。 ' 在图 1中, 计算机接口模块 31 内置了 VGA信号复用电路 314, 用于将 来自 PC机主机的 VGA信号转发到 VGA输出接口 318。当计算机工作在单工 作站方式时,计算机接口模块的这个 VGA输出接口 318可以用来接计算机的 显示器 18。
如图 1, TV视频信号接收电路 412接收来自通信线 32的计算机 10的视 频信号并还原成 S-Video信号, 然后被 TV视频信号转换电路 411转换成复 合视频信号后发送到电视机 20, 我们可以看到计算机 10输出的视频信号最 终显示在电视机 20屏幕上。
如图 1, 电视机接口模块 41内置了 USB声卡 415。 计算机 10输出的双 声道声音信号通过计算机的 USB接口 12、 计算机接口模块 31、 通信线 32、 电视机接口模块 41内部的 TV端 USB驱动收发电路 413、USB Hub电路 414、 USB声卡 415最终被输出到电视机 20上。 外部 USB设备 60接收到的无线 遥控器信号和来自麦克风 50的声音信号, 通过相反的方向, 最终被传输到计 算机 10。
请参阅图 2, 为本发明的单工作站模式,计算机用户和电视机用户通过各 自的键盘、 鼠标或其他设备共同控制同一组运行在计算机操作系统下的应用 软件, 计算机 10的内置声卡 17连接扬声器.17-1和麦克风 17-2, 显示器 18 连接在计算机接口模块 31上。 电视机用户的无线键盘 63、 无线鼠标 62或遥 控设备 61通过无线接收设备连接至 TV端 USB接口 4191并进行相关操作, 数字电视机顶盒 47通过 USB音视频采集压缩设备 45或红外发射器 46与电 视机接口模块 41连接, 电视机接口模块 41通过 TV端音频接口 418、 TV端 视频接口 417与电视机 20连接。
电视机接口模块 41 增加连接来自数字电视机顶盒的电视音视频信号输 入, 这样计算机用户可以在计算机上收看和录制有线数字电视节目, 电视机 用户 5 可以享受电视节目时光平移、 电视节目互动等功能, 也可以观看以往 录制在计算机 10硬盘上的电视节目。
请参阅图 3, 计算机 10、 电视机 20之间通过计算机接口模块 31、通信线 32和电视机接口模块 41连接在一起, 遥控设备 61、 无线鼠标 62和无线键盘 63通过电视机接口模块 41远程控制计算机 10, 计算机 10通过宽带接口接入 互联网。
来自互联网的所有多媒体内容首先由计算机 10进行处理, 计算机 10处 理后的结果以视频和音频的方式发送到电视机 20。 电视机用户 5通过接到电 视机接口模块 41 的 USB设备对多媒体内容进行交互控制。 在电视机接口模 块 41上的数字电视机顶盒的电视音视频信号输入, 使电脑用户可以在电脑上 收看和录制有线数字电视节目, 电视机用户 5 可以享受电视节目时光平移、 电视节目互动等功能, 也可以观看以往录制在计算机 10硬盘上的电视节目。
例如: 湖南卫视正在播放 "大长今" 的电视节目, 电视观众由于走开了 23分钟, 通过时光平移功能, 他可以观看 23分钟前播出的视频。
电视节目时光平移实现方式和操作方法如下。
( 1 ) "大长今"节目通过有线数字电视网传输到用户家中的数字电视机顶 盒, 再接入到电视机接口模块 41 ; 然后通过通信线 32和计算机接口模块 31, 发送到计算机 10。
(2 )电视机用户 5在需要暂时离开电视机前,按计算机遥控器 61上的"电 视暂停"键。
(3 ) 电视机接口模块 41上连接的 USB红外接收器将收到的 "电视暂停" 信号转发给计算机 10。
(4 )计算机 10收到暂停指令后, 对电视节目进行缓存; 电视画面被暂定。
( 5 ) 23分钟后, 电视机用户 5返回后, 按计算机遥控器 61上的 "电视播 放键"。
( 6 ) 计算机 10收到电视播放指令后, 开始播放缓存的 23分钟前的电视 节目, 同时继续缓存当前有线数字电视台仍在继续播放的电视节目。
请参阅图 4, 为电视节目互动的一个例子。 例如, "湖南卫视"正在通过有 线数字电视系统播出 "超女"选拔实况, "湖南卫视" 同时在互联网上设置了 "互动服务器"。 计算机 10已预先下载安装了一个 "湖南卫视"的互动软件。
电视机用户 5在观看"超女"选拔实况时,通过按无线遥控器 61上的"电 视互动键",电视机屏幕上即出现 "超女"选拔 "互动窗口", "超女"选拔实 况和互动投票画面同时显示在电视屏幕上。 · 电视观众可以通过遥控器实施投票, 并通过互动窗口看到投票过程和实 时的投票结果。 这个例子中, 我们设想的投票过程如下需要互动软件配合: 1、 观众想要给 "2#"投票。 通过 "超女"互动窗口的提示, 需要按数字 键 "2 "。
2、 观众按了 "2 " 数字键, 互动窗口中的红颜色变成绿颜色。
3、 观众按确认键, "互动窗口" 出现几秒钟的提示信息, 提示观众投票 完成。
4、 "互动窗口"继续显示各选手的最新得票数。
同时, 电视机 20上的 USB摄像头通过电视机接口模块 41最终连到的计 算机 10。 "湖南卫视"可以在互动服务器通过互联网随时视频采访参与节目的 电视观众, 并将观众的摄像显示在电视频道上, 让遍布全国的电视观众更进 一步地参与到实况电视节目中来。
请参阅图 5, 如图 5所示的双工作站模式, 计算机用户和电视机用户通过 各自的键盘、 鼠标或其他设备各自独立控制一组运行在计算机操作系统下的 应用软件, 各自具有独立的显示内容和声音输出。 计算机 10 的内置声卡 17 连接扬声器 17-1和麦克风 17-2, 显示器 18连接在计算机 10内的显卡 13上, 计算机 10内另加了一块显卡 13-2。 该显卡 13-2与计算机接口模块 31进行连 接。 与单工作站方式相同, 在电视机侧, 电视机用户的无线键盘 63、 无线鼠 标 62或遥控设备通 61通过无线接收设备连接至 TV端 USB接口 4191并进行 相关操作, 数字电视机顶盒 47通过 USB音视频采集压缩设备 45与电视机接 口模块 41连接, 电视机接口模块 41通过音频输出接口 418、 视频输出接口 07 002397
B417与电视机 20连接。
计算机 10安装了显卡及第二显卡, 计算机用户和电视机用户可以同时独 立使用计算机, 各自有独立的显示和声音输入输出, 相互不干扰。为实现双工 作站方式工作, 计算机 10上还需要安装 Windows多工作站共享软件。 与图 2 不同的是, 显示器没有连接在计算机接口模块 31中的视频输出接口。
