Application: Channel hiatus correction method and hdmi device (Patent ID: US20240155185A1)
The patent filed by MediaTek Inc. describes a channel hiatus correction method for an HDMI device. The method involves obtaining a recovery code from scrambled data of a stream, determining a linear feedback shift register (LFSR) value of channels of the HDMI port based on the recovery code and the scrambled data, de-scrambling the stream according to the LFSR value, and displaying video data based on the de-scrambled stream. The invention aims to address channel interruptions in HDMI devices by efficiently recovering and processing data streams.
The patent also outlines specific claims related to the method, including obtaining the stream from a source device through the HDMI port, performing XOR operations on the scrambled data and recovery code to determine the LFSR value, enabling the HDMI port to receive the stream while disabling other ports, and obtaining multiple LFSR values based on an LFSR generator polynomial with different seed values. Additionally, the patent describes an HDMI device incorporating this method, featuring a channel hiatus corrector, a de-scrambler, and a display device to implement the channel correction process. The device is designed to handle TMDS streams and ensure seamless video display by addressing interruptions in the HDMI signal flow.
