随着互联网应用的深入和宽带网络的普及,互联网上涵盖社会方方面面的各 种多媒体内容正日益丰富,通过互联网的各种多媒体通信和交流工具也逐渐转向 主流。互联网正在从最初的通信和信息获取的工具演变为人们工作、学习、沟通、 娱乐等的全方位平台,人们在工作和生活上对互联网的依赖感日渐增大,全球的 上网人数特别是宽带上网人数仍在快速增长中。家庭住宅是人们办公室之外接入 互联网的最主要地点, 因而近年来家庭宽带接入用户数增长最为迅速。
目前, 人们在家中书房通过电脑来近距离欣赏 Internet网上的多媒体内容、 从网上下载电影等各种多媒体文件、存储和观看数码相机的照片、数码摄像机上 的录像等已比较普遍。 问题是, 在书房电脑屏幕上欣赏这些多媒体内容, 尤其是 长时间欣赏, 人们无法获得比较轻松休闲的体验。
而通过电视机在客厅或卧室从较远距离以比较轻松休闲的方式来欣赏网上 或家庭电脑上的多媒体内容, 目前还缺少比较好的手段。 目前最普遍的做法是, 增添一台娱乐电脑,专门用于电视机网上娱乐。这台娱乐电脑其实与用户已有的 家庭电脑功能并无不同,很多家庭难以承受这种重复投资。而且这两台电脑之间 要共享信息和共享上网, 安装和操作方法也颇为复杂。 另外, 由于各种应用软件 频繁升级和病毒在网上的广泛传播, 电脑的维护工作量不小, 增加一台电脑, 即 增加了一台电脑的维护工作量。
另一种方法是, 向 IPTV (网络电视) 运营商申请 IPTV菔务, 通过专门的 IP (网络)机顶盒来实现电视机网上娱乐。 这种方法也有不少问题。 首先, IPTV 服务目前还没有广泛开展, 而且短时间内也无法普及; 同时, IPTV服务所能提 供的内容, 完全受 IPTV运营商的限制。 而且 IP机顶盒一般不能共享家庭电脑 上的内容, 即使要共享电脑上的内容, 操作也很复杂。 当然, IPTV服务费也是 一个问题, 在宽带上网费之外增加一笔 IPTV服务费, 对于很多家庭而言是一个 额外的经济负担,
如何通过电视机以比较轻松休闲的方式来欣赏网上或家庭电脑上的多媒体 内容而不会大幅度增加成本、不过多增加操作复杂度和维护工作量, 一直是没有 解决的问题。

细叙本发明图 1的工作原理: 图 Γ中,计算机 10的显卡接口 AI 出的视频信号和声卡输出的音频信号, 在计算机 PC盒 31的 PC音视频采集压缩通信电路 312中 ¾行压缩编码,成为适 合网络传送的数据, 发给 PC端 IP网络通信模块 316。 计算机 PC盒 31中的 PC 端 USB接口模块电路 313负责接收来自计算机通信接口 12的 USB第一信号, 经编码成为控制第一信号后发给 PC端 IP网络通信模块 316;并从 PC端 IP网络 通信模块 316送来的控制第二信号中解出 USB第二信号并转发给计算机 10。 PC 端 IP网络通信模块 316负责将收到的视音频信号和第一控制信号进行网络编码、 打包、 编帧, 然后发送到 IP网络 32上; 并从 IP网络 32上接收分离第二控制信 号。
如图 1, TV端 IP网络通信模块 416接收来自 IP网络 32的信息, 并分离音 视频信号和第一控制信号。 音视频信号送给 TV数字音视频通信解码电路 412, TV数字音视频通信解码电路 412将其解压还原成标准的视频、 音频信号, 发送 到电视机 20, 我们就可以看到计算机 10输出的视频信号最终显示在电视机 20 屏幕上。 控制信号送给 TV端 USB接口模块 411, 电视机 TV盒 41中的 TV端 USB接口模块电路 411 负责从接收到的第一控制信号中还原出来自计算机通信 接口 12的 USB第一控制信号, 通过 USB接口 4191发给 USB设备 60; 并从接 收来自 USB设备 60的 USB第二信号, 经编码成第二控制信号后发给 TV端 IP 网络通信模块 416, 后通过 IP网络 32送给计算机 PC盒 31。
参照图 16、 图 2, 计算机 PC盒 31还可以内置 VGA信号复用模块 314, 用 于将来自计算机 10的 VGA信号转发到 VGA输出接口 318。当计算机 10工作在 单工作站方式时,计算机 PC盒 31的这个 VGA输出接口 318可以用来接计算机 的显示器 18。
参照图 17和图 18, PC端 IP网络通信模块 316是由以太网 HUB电路、 PLC 网桥模块和电力线模拟接口电路, 或者射频接口电路组成的。 以太网 HUB模块 将 PC音视频采集压缩通信电路 312的音视频数据和 PC端 USB接口电路 313的 控制信息, 按照不同的地址进行转发。 PLC网桥模块和通信接口按照 IP网络联 网方式的不同, 可以是 RF无线通信、 电力线通信或其他方式。
如图 20, TV端 USB接口模块 411内置 TV端 USB通信电路 413、 USB hub 电路 414、 USB声卡 415、 USB红外接收器电路 421。所述的 USB声卡 415集成 有 TV端音频输出接口418和 TV端麦克风接口 4192
USB声卡 415、USB红外接收器电路 421以及 USB接口 4191连接在 USB hub 电路 414上, 并通过 TV端 USB通信电路 413、 TV端 IP网络通信模块 416、 IP 网络 32、 PC端 IP网络通信接口、 PC端 IP网络通信模块 316、 PC端通信控制 接口电路 313、 PC端通信接口连接到计算机的 USB Host。 这种方式下, 电视机 TV盒可以提供计算机的 USB功能。

计算机 10输出的声音信号可以通过计算机的 USB接口 12、 计算机 PC盒 31、 IP网络 32、 电视机 TV盒 41内部的 TV端 USB接口模块 411、 USB Hub电 路 414、 USB声卡 415最终被输出到电视机 20上; 或者通过 PC端音视频采集 压缩通信电路 312、 PC端 IP网络通信模块 316、 IP网络 32、 TV端 IP网络通 信模块 416、 TV数字音视频通信解码电路 412最终被输出到电视机 20上。
图 2所示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 PC盒 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 TV盒 41连接, 电视 机 TV盒 41通过 TV端音频输出接口 418、 TV端视频输出接口 417与电视机 20 连接。
电视机 TV盒 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。
如图 3所示, 计算机 10、 电视机 20之间通过计算机 PC盒 31、 IP网络 32 和电视机 TV盒 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 TV盒 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 ΤΎ 盒 41的 USB设备对多媒体内容进行互动控制。 在电视机 TV盒 41上的数字电 视机顶盒的电视音视频信号输入, 使电脑用户可以在计算机 10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 TV盒 41 ; 然后通过通信线 32和计算机 PC盒 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 TV盒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己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 TV盒 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, 图 5是双工作站模式, 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。两者各自欣赏一组独立的显示和声音, 两者 欣赏的独立显示分别来自显卡接口 All 和第二显卡接口中之一, 两者欣赏的独 立声音分别来自音频输出接口 A13和 USB声卡 415或外部 USB声卡之一。
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内的显卡接口 Al l上, 计算机 10内另加了一块显卡。 该显卡有第二 显卡接口并与计算机 PC盒 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 TV盒 41连接, 电视机 TV盒 41通过音频输出接 口 418、 视频输出接口 B417与电视机 20连接。
由于计算机 10安装了显卡及第二显卡, 第二显卡有第二显卡接口。 计算机 用户和电视机用户可以同时独立使用计算机 10, 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 18没有连接在计算机 PC盒 31中 的视频输出接口。
请参阅图 6, 为双工作站改进模式, 计算机 10的 PCI显卡、 USB接口电路 和计算机 PC盒集成为一块 PCI综合卡 19。如图所示,计算机 10有显卡接口 Al l 和一块 PCI综合卡 19, 显示器 18接在显卡接口 All上, 电脑用户通过显示器 18和计算机侧的键盘和鼠标来使用计算机 10, 从计算机 10到电视机 20的视频 通过 PCi综合卡 19输出, 电视机用户通过接在电视机 TV盒 41侧的无线PC键 盘或遥控器远程操作计算机 10, 电脑用户和电视机用户相互不干扰。

如图 8所示, 计算机 PC盒 31由视频转换芯片 Ul、 视频压缩处理芯片 U4、 AD采样芯片 U3构成 PC视频采集压缩通信电路 312, Q1〜Q3构成 VGA信号 复用电路 314, 输出 VGA信号到 VGA输出接口 318, 视频输出接口 318连接计 算机显示器 18。
视频转换芯片 U1将 VGA信号转换为复合视频,再经 AD采样芯片 U3采样 为数字信号, 然后由视频压缩处理芯片 U4进行视频压缩, 最后成为适合 IP网 络传输的视频码流。
如图 9-1所示, 计算机 PC盒 31中, PC端 USB接口部分由 USB处理主芯 片 U11构成。 USB处理主芯片 U11的第 33脚和第 28脚通过 R14、 R16连接计 算机 10的 USB模块接口 12。处理后的通信数据经以太网 PHY芯片 U12变成 IP 网络数据流 (USB 处理主芯片 U11 为 Xilinx 公司 Spartan系列 FPGA 芯片 XCS40XL型号的芯片)。

如图 10所示, IP网络通信模块由电力线通信处理主芯片 U21、 控制信息存 贮芯片 U22、 以太网 PHY芯片 U23、 以太网 HUB芯片 U24构成。 发送数据时, 视音频信号和控制信号分别接入以太网 HUB芯片 U24, 经转换、 编码、 组帧后 合成一路 IP数据。 再由以太网 PHY芯片 U23送到电力线通信处理主芯片 U21, 经处理后由电力线通信处理主芯片 U21通过变压线圈 Tl经过电力线接口接入电 力线网络。 接收数据时, 电力线通信处理主芯片 U21通过变压线圈 T1经过电力 线接口从电力线网络取出 IP数据流, 经以太网 PHY芯片 U23送到以太网 HUB 芯片 U24, 再由以太网 HUB芯片 U24解帧并根据不同的地址发送给视音频单元 和控制信息处理单元 (电力线通信处理主芯片可以采用 INTELION 公司的 INT5200) o
请参阅图 11,'该图是本发明中电视机 TV盒中 TV端 USB接口模块的一种 实施例的电原理图。 从 TV端 IP网络通信模块经过 PHY芯片 U35连接到 USB 数据处理芯片 U34, USB数据处理芯片 U34负责 USB数据到 IP数据的编解码 处理,并连接 USB Hub电路 414, USB Hub电路 414由 USB Hub芯片 U31构成, USB Hub芯片 U31连接 TV端红外接收电路 421,音频处理芯片 U32和电容 C7、 C8、 C5、 C4、 C3, 晶体振荡器 Y3, 电阻 R8、 R9、 Rll一起构成 USB声卡 415, 连接电视机的双声道音频输入端和麦克风输入。
图 12-1、 图 12-2图 13、 图 14为本发明在实施过程中, 针对不同的应用, 系统的各个部分可以采用不同的组合方式,以降低实施成本或改进用户使用的方 便性。图 12-1为 IP网络是有线局域的结构; 图 12-2为 IP网络是通过电力线搭 建的局域网结构; 图 13为 IP网络是通过无线通信搭建的局域网结构; 图 14为 IP网络是通过无线 /电力线搭建的局域网结构。
请参阅图 15,为通过电视机 TV盒将有线数字电视信号发送到计算机的一种 实施例。 如图所示, 来自数字电视机顶盒 47的有线数字电视音视频信号, 经过 USB音视频采集压缩盒 45, 通过电视机 TV盒 41 , 最终被送到计算机 10。 图 15中, 电视机 TV盒 41外接了一个 USB红外发射器 46, 这个发射器的朝向必 须对准有线数字电视机顶盒 47的红外接收器, 这样, 电脑用户在收看电视节目 时可以远程调台。
图 15中, 电视机 TV盒 41还外接了一个 USB5.1声道的声卡 415, 这个声 卡通过光纤 43连接到家庭音响系统 44, 这样, 电视机用户 5可以欣赏到来自计 算机 10的高质量音频信号。图中,电视机 TV盒 41的 USB设备 601连接 USB-Hub 电路, 具有多个 USB接口 4191-1、 4191-2、 4191-3连接多个 USB设备。
