下面结合附图对技术方案的实施作进一步的详细描述。
本发明实施例提供的一种切换视频源的方法, 如图 1 所示, 包括以下 步骤:
步骤 101、检测到当前可用的至少一个视频源, 将所述视频源以缩略图 的形式进行视频源列表显示。
步骤 102、获取视频源选定事件, 将从所述视频源列表显示中选定的视 频源切换为当前视频源并进行显示播放。
基于上述由步骤 101-102组成的实施例而言, 步骤 101中,检测到当前 可用的至少一个视频源, 具体包括: 检测通过至少一个视频接口对应接入的至少一个视频源; 所述视频源 包括 VGA输入源、 HDMI输入源、 GUI界面视频输入源中的至少一种类型。
基于上述由步骤 101-102组成的实施例而言, 步骤 101中,将所述视频 源以缩略图的形式进行视频源列表显示, 具体包括:
获取检测得到的至少一个视频源、 及视频源对应的视频信息; 根据所述视频源对应的视频信息生成所述缩略图, 以缩略图的形式进 行视频源列表显示。
这里, 所述才艮据所述视频源对应的视频信息生成所述缩略图, 以缩略 图的形式进行视频源列表显示, 具体包括:
若根据所述视频信息包括的视频码流生成所述缩略图, 当前视频源的 视频码流正常输出, 则生成当前视频源对应的缩略图至视频源列表中进行 显示; 当前视频源的视频码流非正常输出, 则将描述当前视频源内容的图 标至视频源列表中进行显示。 也就是说, 当前视频源的视频码流非正常输 出, 无法生成当前视频源对应的缩略图进行显示, 此时, 仅将描述当前视 频源内容的图标至视频源列表中进行显示。
基于上述由步骤 101-102组成的实施例而言, 步骤 102中,获取视频源 选定事件, 将从所述视频源列表显示中选定的视频源切换为当前视频源并 进行显示, 具体包括: 获取视频源点击选定事件, 将选定的视频源切换到 当前与会者视频画面中进行显示; 或者, 获取视频源拖拽选定事件, 将选 定的视频源切换到当前与会者视频画面中进行显示。
本发明实施例的一种切换视频源的装置, 所述装置位于显示电子设备 中, 所述显示电子设备具体包括触控显示屏或非触控显示屏; 所述装置如 图 2所示, 包括:
检测模块 11, 配置为检测当前可用的至少一个视频源; 显示模块 12, 配置为收到所述检测模块上报的视频源, 将所述视频源以缩略图的形式进 行视频源列表显示, 获取视频源选定事件, 将从所述视频源列表显示中选 定的视频源切换为当前视频源并进行显示。
基于上述由检测模块 11和显示模块 12组成的实施例而言, 检测模块 11 配置为检测通过至少一个视频接口对应接入的至少一个视频源; 所述视 频源包括 VGA输入源、 HDMI输入源、 GUI界面视频输入源中的至少一种 类型。
基于上述由检测模块 11和显示模块 12组成的实施例而言, 显示模块 12 包括第一显示子模块; 所述第一显示子模块, 配置为获取检测得到的至 少一个视频源、 及视频源对应的视频信息; 根据所述视频源对应的视频信 息生成所述缩略图, 以缩略图的形式进行视频源列表显示。 所述第一显示 子模块具体可以为图 3中的视频源列表显示输出器 22。
基于上述由检测模块 11和显示模块 12组成的实施例而言, 显示模块 12 包括第二显示子模块; 所述第二显示子模块, 配置为获取视频源点击选 定事件, 将选定的视频源切换到当前与会者视频画面中进行显示; 或者, 获取视频源拖拽选定事件, 将选定的视频源切换到当前与会者视频画面中 进行显示。 所述第二显示子模块具体可以为图 3 中的与会者视频显示输出 器 21。
本发明实施例的一种显示装置, 所述显示装置包括触控显示屏或非触 控显示屏; 所述显示装置包括显示器, 显示器配置为将获得的视频源以缩 略图的形式进行视频源列表显示输出, 获取视频源选定事件, 将从所述视 频源列表显示中选定的视频源切换为当前视频源并进行显示输出。
基于本发明实施例的上述显示器而言, 所述显示器包括第一显示单元; 所述第一显示单元, 配置为获取检测得到的至少一个视频源、 及视频源对 应的视频信息; 根据所述视频源对应的视频信息生成所述缩略图, 以缩略 图的形式进行视频源列表显示。 所述第一显示单元如图 3 所示, 具体为视 频源列表显示输出器 22。
基于本发明实施例的上述显示器而言, 所述第一显示单元, 配置为若 根据所述视频信息包括的视频码流生成所述缩略图, 当前视频源的视频码 流正常输出, 则生成当前视频源对应的缩略图至视频源列表中进行显示; 当前视频源的视频码流非正常输出, 则将描述当前视频源内容的图标至视 频源列表中进行显示。
基于本发明实施例的上述显示器而言, 所述显示器包括第二显示单元; 所述第二显示单元, 配置为获取视频源点击选定事件, 将选定的视频源切 换到当前与会者视频画面中进行显示; 或者, 获取视频源拖拽选定事件, 将选定的视频源切换到当前与会者视频画面中进行显示。 所述第二显示单 元如图 3所示, 具体为与会者视频显示输出器 21。
基于本发明实施例的上述显示器而言, 所述视频源列表显示输出在所 述显示屏中的任一个屏幕位置, 与显示输出的所述当前视频源相邻。
这里, 显示输出的当前视频源可以为与会者视频画面。 视频源列表显 示输出位于显示屏中右侧, 与所述与会者视频画面相邻。 需要重申的是, 视频源列表可在整个屏幕的任何位置显示(图 4举的例子为整个屏幕的右 侧), 如果视频源正常将以视频的缩略图作为该视频源的图标, 否者只显示 一个能表达视频源信息的图标。
以下对本发明实施例进行进一步举例阐述:
本发明实施例的方案可以应用在会议电视领域中, 会议多画面的显示 模式选择过程中, 能自动检索到当前可用的视频源, 并以缩略图的形式(区 别于现有图标形式的显示, 相对而言是一种动态显示)显示在画面的旁边, 实现动态切换视频源。 此时可通过但不限于点击或拖拽的方式改变当前显 示画面的视频源。
在实现动态切换视频源的过程中主要由几个模块完成, 如图 2 所示, 包括检测模块 11、 显示模块 12。 检测模块 11具体是: 获取当前到当前终 端的视频源, 比如视频 VGA输入源, HDMI输入源, GUI界面视频输入源 等, 能够获取到其对应的视频内容。 一旦有新的视频源接入时, 及时的更 新当前视频源列表, 并上报给显示模块 12。 显示模块 12是: 收到显示上报 的当前视频源列表以及各个视频源的视频信息, 这些信息包括但不限于: 视频格式、 分辨率、 视频码流等。
其中, 显示模块 12由两部分显示功能组成: 一部分显示视频源列表, 如果某一路视频源码流正常, 将会显示以缩略图的形式显示在视频源列表 中, 否则仅显示一个可以说明该视频源内容的图标。 另一部分显示会议视 频中的与会者视频。
釆用本发明实施例的好处是: 当终端接入的视频源比较多时, 比如: 移动摄像头、 VGA1、 HDMI1、 VGA2、 HDMI2 等等, 如果那么多 是视频源仅仅只以现有图标的形式显示在视频源列表, 会给用户造成一种 视频源混淆的现象, 容易切换错误导致切换异常。 釆用本发明实施例, 视 频源以缩略图的形式表现时, 是一种能够动态切换视频源的方案, 用户便 能直接体会到 "所见即所得", 大大的增加操作的方便性。 也就是说, 一方 面, 将终端检测到的视频源以缩略图形式的视频源列表罗列到画面的旁边 进行显示, 便于实时的视频源切换; 另一方面、 罗列的视频源列表中, 如 果该视频源有码流, 便会以该视频的缩略图的形式显示出来, 当终端可用 的视频源较多的时候, 以缩略图的形式会使用户对可用的视频源一目了, 实现 "所见即所得"。
以下对本发明实施例的适用场景进行举例阐述:
应用实例: 在会议电视领域中, 会议多画面的显示模式选择过程的场 景。
本实例中的显示装置得到的输出显示界面为如图 4所示的画面, 在会 议多画面的显示模式选择过程中, 能自动检索到当前可用的视频源, 如视 频源 1、 2...N构成的视频源列表, 且视频源是以缩略图的形式显示在与会 者视频图像画面的右侧, 在其他场景中, 视频源列表可以显示在与会者视 频图像画面的上、 下、 左侧等显示装置显示界面的任一个屏幕中位置。 视 频源是以缩略图的形式显示是一种动态显示的效果, 区别于现有技术是以 图标的形式这种静态的显示。 所述缩略图显示是指: 可以看到视频播放到 哪一段码流, 如视频码流的 10%时所定格显示的一段视频图像画面, 釆用 本实例缩略图显示的好处是: 在视频源很多的情况下, 有直观的视频图像 画面, 使用者不仅能知道是哪个视频, 而且知道当前视频播放到哪个阶段, 方便查询, 以便使用者根据视频源查询结果来决策当前是否需要切换到其 他视频源, 还是接续播放当前视频源, 不会出现视频源切换异常的情况。 而现有技术图标的形式的列表显示, 只能知道有几个视频源, 不好区分和 查询, 不利于使用者做出切换决策, 常常出现切换异常, 把不该切换的视 频切换了, 或者切换到的视频并不是当前需要播放的, 在多人参与的会议 电视场景下, 这种错误会带来很不好的观感, 甚至会导致会议中断。
视频源以缩略图的形式显示在与会者视频图像画面的右侧, 符合使用 者日常操作的使用习惯, 因为通常人们都是右手操作, 显示在右侧, 方便 用户通过拖拽的方式将选定的视频源拖放到与会者视频图像画面中进行显 示, 来改变画面的视频源。 但是, 再次指出, 并不限定于显示在右侧, 因 为有很多左撇子, 通常釆用左手操作, 显示在左侧, 方便左撇子的用户通 过拖拽的方式将选定的视频源拖放到与会者视频图像画面中进行显示。
根据与会者的数量和输出显示画面的需求的不同, 显示装置控制输出 的显示界面可以有多种布局组合, 如图 5-图 7的布局组合, 在实际操作中 并不限制于这些组合方式, 可以根据上述需求进行预设置, 由显示装置或 者切换视频源的装置的显示模块来根据预设值控制输出对应的显示界面。 图 5为本发明实施例的动态切换视频源的 2个与会者的显示示意图, 显示界面包括: 视频源 1、 2...N构成的视频源列表, 且视频源是以缩略图 的形式显示在与会者视频图像画面的右侧, 显示界面还包括 2个与会者视 频图像画面。
图 6为本发明实施例的动态切换视频源的 3个与会者的显示示意图, 显示界面包括: 视频源 1、 2...N构成的视频源列表, 且视频源是以缩略图 的形式显示在与会者视频图像画面的右侧, 显示界面还包括 3 个与会者视 频图像画面。
图 7为本发明实施例的动态切换视频源的 4个与会者的显示示意图, 显示界面包括: 视频源 1、 2...N构成的视频源列表, 且视频源是以缩略图 的形式显示在与会者视频图像画面的右侧, 显示界面还包括 4个与会者视 频图像画面。
对于图 5-图 7这几种不同与会者数目参会时, 整个屏幕的显示情况下, 都可以通过在右侧的显示的视频源列表去改变视频源, 以实现视频源的切 换。 改变视频源的方式包括但不限于: 点击、 拖拽。 可以在右侧的显示的 视频源列表中用双击的方式, 将双击的视频切换到与会者视频图像画面; 或者, 用拖拽的方式将拖拽的视频切换到与会者视频图像画面。
如果视频源正常显示时, 将以视频的缩略图作为该视频源列表的图标 进行, 如果视频源非正常显示, 比如目前视频处于緩冲阶段, 切换了也没 法播放, 则只显示一个能表达视频源信息的图标, 而不是缩略图形式显示。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围。 工业实用性
本发明实施例检测到当前可用的至少一个视频源; 将所述视频源以缩 略图的形式进行视频源列表显示, 获取视频源选定事件, 将从所述视频源 列表显示中选定的视频源切换为当前视频源并进行显示。 釆用本发明实施 例, 由于所述视频源以缩略图的形式进行视频源列表显示, 是一种动态显 示方式, 方便用户选取, 进而从所述视频源列表显示中选定的视频源切换 为当前视频源并进行显示, 从而提高切换效率及避免切换异常。
