    • A TMDS receiver includes a plurality of data channels, a clock channel, and an off-line mode detector. Each data channel receives a video signal and the clock channel receives a clock signal. Each data channel comprises a channel decoder for decoding the signals received by the corresponding receiving channel. The off-line mode detector detects an off-line mode detector, and then turns on a plurality of first data channels for a first predetermined period to determine an operation mode of video signal transmitted on said first data channels if the activity of the clock signal is valid. The off-line mode detector also activates a plurality of second data channels among the plurality of data channels according to the operation mode if the operation mode is determined as valid.
    • TMDS接收机包括多个数据信道,时钟信道和离线模式检测器。 每个数据通道接收视频信号,时钟信道接收时钟信号。 每个数据信道包括用于对由相应接收信道接收的信号进行解码的信道解码器。 离线模式检测器检测离线模式检测器,然后在第一预定周期内接通多个第一数据信道,以确定在所述第一数据信道上发送的视频信号的操作模式,如果时钟信号的活动 已验证。 如果操作模式被确定为有效,则离线模式检测器还根据操作模式激活多个数据通道中的多个第二数据通道。
