点评：一种交互式多视点视频系统的图像信号处理方法，通过在服务端编码存储不同预测方式下得到的多视点视频信号码流以及关联视点间完整的视差场码流，利用反馈的用户端视点选择信息和显示设备类型信息，从视点可分解的结构式码流中选择合适的1个视点(用于单目显示)或2个视点(用于立体显示)或者最多4个视点(用于2个虚拟视点的立体显示)数据，从而实现多视点视频信号的部分传输，降低系统对传输带宽的要求以及用户端系统复杂度的要求，使得在给定网络带宽的条件下能传输更多的节目，服务更多的用户，使得数字交互式多视点电视接收机的成本更低。

Comment: The invention discloses an image signal processing method for interactive multi-viewpoint video system, coding and storing multi-viewpoint video signal code streams and complete disparity field code streams between related viewpoints, obtained in different forecasting modes, and using fedback user end viewpoint selection information and display unit type information to properly select a viewpoint (used for single eye display) or two viewpoints (used for 3D display) or at most four viewpoints (used for 3D display of two virtual viewpoints) from the viewpoint-resolvable structural code streams, so as to implement partial transmission of multi-viewpoint video signals and reducing system's requirements for transmission bandwidth and requirements for user end system complexity, making it able to transmit more programs and service more users in the given network bandwidth and making the cost of a digital interactive multi-viewpoint TV receiver be lower.
