Abstract:
1. A video receiving apparatus including an input terminal to receive pixel-based video data transmitted with pixel clock synchronized with the video data, comprising: a separation unit configured to separate auxiliary data added to the video data from the video data obtained at the input terminal; an information acquisition unit configured to acquire information on the number of horizontal pixels and the number of vertical pixels for the input video data from the auxiliary data separated at the separation unit; and a determination unit configured to directly determine a type of the input video data by using the information on the number of horizontal pixels and the number of vertical pixels that is obtained at the information acquisition unit, wherein the determination unit accesses a database that cross-references numbers of horizontal pixels and numbers of vertical pixels to respective video types, and determines the type of the input video data by determining which of the video types in the database corresponds to the number of horizontal pixels and the number of vertical pixels for the input video data, and in the case that no video type in the database corresponds to the number of horizontal pixels and the number of vertical pixels for the input video data, the determination unit determines the type of the input video data by determining which of the video types in the database corresponds, within an acceptable margin of difference, to the number of horizontal pixels and the number of vertical pixels for the input video data.
