    • A shift register includes a plurality of electrically connected shift units. Each shift unit includes a pull-up circuit, a pull-up driving circuit, a pull-down circuit, and a pull-down driving circuit. The pull-up circuit outputs a first signal to an output node according to the first signal and a voltage of a driving node. The pull-up driving drives the pull-up circuit according to an output voltage of the previous shift unit. The pull-down driving circuit outputs a low level voltage to the driving node and the output node according to the first signal and a second signal. The pull-down circuit resets the pull-up driving circuit according to the voltage of the output node and outputs the low level voltage to the output node and the driving node according to a third signal and a fourth signal.

    • For each of plural blocks (e.g., 8×16 blocks) in a source interlaced video frame, a video encoder measures vertical intensity level fluctuation between neighboring lines and between alternating lines in the block, and determines an interlace effect status value for the block. For example, the encoder calculates a ratio between the fluctuations of neighboring and alternating lines and compares the ratio with one or more thresholds. The encoder also can measure horizontal intensity level fluctuation and compare it with vertical intensity fluctuation. The encoder determines a frame-level interlace coding mode (e.g., frame mode or field mode) for the frame based at least in part on the interlace effect status values. The encoder can represent a frame-level interlace coding mode decision with a bitstream element, and a decoder can perform one or more video decoding functions based at least in part on the value of the bitstream element.
    • 对于源隔行视频帧中的多个块(例如,8×16块)中的每一个,视频编码器测量相邻行之间和块中的交替行之间的垂直强度级别波动,并且确定块的隔行效果状态值。 例如,编码器计算相邻线和交替线的波动之间的比率,并将该比率与一个或多个阈值进行比较。 编码器还可以测量水平强度水平波动,并将其与垂直强度波动进行比较。 编码器至少部分地基于隔行扫描效果状态值来确定帧的帧级交错编码模式(例如,帧模式或场模式)。 编码器可以用比特流元素表示帧级隔行编码模式决定,并且解码器可以至少部分地基于比特流元素的值来执行一个或多个视频解码功能。

    • Techniques and tools for skip modes in encoding and decoding of inter-layer residual video are described. For example, an encoder encodes multiple macroblocks of a picture of inter-layer residual video. For a current macroblock that is skipped, the encoder selects a skip mode from among multiple available skip modes and uses the selected skip mode when encoding the current macroblock. The skip modes can include intra skip mode and predicted-motion skip mode. A corresponding decoder, for the current macroblock, selects and uses the skip mode for the current macroblock during decoding. As another example, an encoder encodes multiple channels of a picture of inter-layer residual video. For each channel, the encoder determines whether to skip the channel. The encoder signals channel skip information to indicate which channels are skipped. A corresponding decoder parses the channel skip information and determines on a channel-by-channel basis whether to skip the respective channels.
    • 描述了层间残差视频编码和解码中跳过模式的技术和工具。 例如,编码器编码层间残留视频的图像的多个宏块。 对于跳过的当前宏块,编码器从多个可用跳过模式中选择跳过模式,并且在对当前宏块进行编码时使用所选择的跳过模式。 跳过模式可以包括帧内跳过模式和预测运动跳过模式。 对于当前宏块,对应的解码器在解码期间选择并使用当前宏块的跳过模式。 作为另一示例,编码器对层间残留视频的图像的多个信道进行编码。 对于每个通道,编码器确定是否跳过通道。 编码器信号通道跳过信息以指示哪些通道被跳过。 相应的解码器解析信道跳过信息,并且逐个信道地确定是否跳过相应的信道。
