摘要： From a bit stream, at least the following are decoded: a stereoscopic image of first and second views; a maximum positive disparity between the first and second views; and a minimum negative disparity between the first and second views. In response to the maximum positive disparity violating a limit on positive disparity, a convergence plane of the stereoscopic image is adjusted to comply with the limit on positive disparity. In response to the minimum negative disparity violating a limit on negative disparity, the convergence plane is adjusted to comply with the limit on negative disparity.

摘要： In one embodiment, a communication device samples a particular frequency hopping sequence during only a particular specified sub-timeslot of a timeslot. If a transmission energy is not detected during the specified sub-timeslot, the device turns off its receiver for a remainder of the timeslot. Otherwise, it continues to sample the particular frequency hopping sequence for at least one or more additional sub-timeslots of the remainder of the timeslot. In another embodiment, a communication device determines whether a neighboring communication device is operating in a first mode or a second mode. If in the second mode, it transmits a transmission to the neighboring communication device starting at any sub-timeslot of the plurality of sub-timeslots. If in the first mode, it transmits the transmission to the neighboring communication device while ensuring that the transmission is actively energized during a particular specified sub-timeslot.
摘要翻译：在一个实施例中，通信设备仅在时隙的特定指定子时隙中采样特定的跳频序列。如果在指定的子时隙期间未检测到传输能量，则该设备在时隙的剩余时间内关闭其接收机。否则，它继续针对时隙的其余部分的至少一个或多个附加子时隙对特定跳频序列进行采样。在另一个实施例中，通信设备确定相邻通信设备是否在第一模式或第二模式中操作。如果在第二模式中，则从多个子时隙的任何子时隙开始向相邻通信设备发送传输。如果在第一模式中，则将传输发送到相邻通信设备，同时确保在特定指定子时隙期间传输被激活。
