A Direct Conversion Line Coding Based on the Similar Property of Image Pixels

Between the display panel and the video driver, fiber is used to transfer the uncompressed video data. Especially for head-mounted display, the video cable can be replaced by fiber. Choosing an appropriate line coding to simplify the circuit structure and reduce the system power is a challenging problem. Based on the similar property of adjacent pixels, a new Direct Conversion line coding is presented. For the characteristics of similar of adjacent pixels in uncompressed video, the location for binary data of adjacent pixels are changed directly, then the processed video signals are serialized in order to facilitate the fiber transmission . Compared with other line codes, this method can greatly reduce the complexity of the video transmission system and power of system. Also the proposed scheme has the features of high efficiency and no error multiplication. The results of simulation show that: bit stream of video provided by the proposed scheme contains adequate timing information and the low-frequency components are reduced. The bit stream can adapt to requirements of transmission in fiber channel.
