    • An image depth information refreshing method applied to an image depth information refreshing device is disclosed. The image depth information refreshing device includes a storage unit and an arithmetic logic unit. The storage unit stores a previous depth diagram corresponding to a previous image. The image depth information refreshing method includes the following steps. The arithmetic logic unit divides a current image captured by an image capturing unit into multiple image blocks. The arithmetic logic unit calculates a depth reference value of each image block according to the previous depth diagram, and determines a weight of each image block according to the depth reference values. The arithmetic logic unit determines a refreshing frequency of each image block according to the weights. The arithmetic logic unit respectively refreshes the image block according to the refreshing frequencies of the image blocks, and generates a current depth diagram corresponding to the current image.

    • STM traffic, e.g. voice and video telephony (VT), as well as packet mode (e.g. ATM) traffic, e.g. broadcast digital video, interactive television, and data, are transmitted via a multiple access broadband fiber/coaxial cable network. Customer premises equipment (CPE) at stations, and a bandwidth controller, which may be at a head end or central office, with which all stations communicate, work together to adapt to the changing demands of the traffic mix, and efficiently allocate bandwidth to a variety of bursty and isochronous traffic sources. The bandwidth allocation defines two types of time slots, STM and ATM, and divides each frame into two corresponding STM and ATM regions. The boundary between the regions can be changed dynamically. A contention access signaling channel is provided in the STM region, for call control and set-up requests. Within the STM region, the time slots can be of variable length and be allocated on a per call basis; the length of the time slots is proportional to the bandwidth requirement of STM calls. Within the ATM region, the time slots are of fixed length, each capable of accommodating one ATM cell. Further, the fixed length ATM time slots may be reserved for a particular user for the duration of a call, or may be shared through a contention process. At least one contention ATM time slot is always made available for signaling messages related to ATM call control and set-up requests. The downstream time frame is structured in a similar manner, but includes an additional MAP field to transmit to the stations ATM time slot allocation and status information for time slots in the upstream channel.
    • STM业务,例如 语音和视频电话(VT),以及分组模式(例如ATM)业务,例如。 广播数字视频,交互式电视和数据通过多址宽带光纤/同轴电缆网络传输。 站点的客户端设备(CPE)以及可能位于所有站点通信的前端或中心局的带宽控制器,一起工作以适应流量混合的不断变化的需求,并且有效地将带宽分配给 各种突发和同步流量来源。 带宽分配定义了两种类型的时隙STM和ATM,并将每个帧划分为两个对应的STM和ATM区域。 区域之间的边界可以动态变化。 在STM区域中提供争用接入信令信道,用于呼叫控制和建立请求。 在STM区域内,时隙可以是可变长度,并且按每个呼叫分配; 时隙的长度与STM呼叫的带宽要求成比例。 在ATM区域内,时隙是固定长度的,每个时隙可容纳一个ATM信元。 此外,固定长度的ATM时隙可以在呼叫期间为特定用户保留,或者可以通过争用过程共享。 总是使至少一个争用ATM时隙可用于与ATM呼叫控制和建立请求有关的信令消息。 下游时间帧以类似的方式构成,但是包括附加的MAP字段,用于向站中的ATM时隙分配和上行信道中的时隙的状态信息进行发送。
