Technical Problem

[0006]有鉴于此，本发明公开一种直播画面生成方法及相关装置，以解决隐私泄露风险和有效信息遮挡问题

Benefits of technology

[0036]从上述的技术方案可知，本发明公开了一种直播画面生成方法及相关装置，当接收到直播画面绘制指令时，根据数字白板的当前画面缩放状态，在主线程中对白板画面中的所有可呈现元素进行全量绘制，生成在用户操作界面显示的白板画面，基于所有可呈现元素预先添加的元素类型标识，从所有可呈现元素中筛选出元素类型标识为核心有效内容标识的核心有效内容元素，在独立子线程中，仅对筛选出的所有核心有效内容元素进行绘制操作，生成直播画面并输出至直播客户端进行显示。本发明预先将白板画面中的所有可呈现元素划分为核心有效内容元素与非核心冗余元素。在白板画面绘制阶段，对所有元素进行全量绘制以保证本地显示完整，并筛选出核心有效内容元素，通过异步处理绘制直播画面，确保最终同步至直播间的画面仅包含核心有效内容。因此，有效阻断了系统用户界面、内部文档等冗余信息的直播传输，从根源上消除隐私泄露风险，同时避免有效信息被遮挡，从而提升了观众获取核心内容的效率，保障了直播交互的有效性。

Abstract

The application discloses a live picture generation method and related device, and relates to the live broadcast field.When a live picture drawing instruction is received, all presentable elements in the whiteboard picture are drawn in the main thread according to the current picture zoom state of the digital whiteboard to generate the whiteboard picture, and based on the element type identifiers added in advance for all presentable elements, core effective content elements are screened out, and only the screened core effective content elements are drawn in the independent sub-thread to generate the live picture and output to the live client for display.The application divides all presentable elements into core effective content elements and non-core redundant elements.In the whiteboard picture drawing stage, all elements are drawn in full, and through an asynchronous processing mechanism, the core effective content elements screened out are drawn in the live picture, so that it is ensured that the final synchronization to the live room picture only contains core effective content, and the problems of privacy leakage risk and effective information shielding are solved.
