    • A video processing apparatus, including: power-up circuitry; an input for receiving encoded video signals; a memory having stored therein processing instructions for processing the encoded video signals to provide an output signal; a decoder, coupled to the input, for processing the received encoded video signals in accordance with the processing instructions; a first controller, coupled to the memory and decoder, for controlling operation of the decoder to process the encoded video signals in accordance with the processing instructions; and a second controller, coupled to the first controller, memory and power up circuitry, wherein, the second controller in response to a start up procedure restricts operation of the first controller and validates the processing instructions, and upon validation of the processing instructions un-restricts operation of the first controller thereby allowing the controller to read the processing instructions from the memory.

    • An apparatus for providing reserved connections between end stations, in a network, such as the Internet, capable of providing prioritized communications, comprises a switch in packet communications with end stations. The switch detects and forwards packets that contain prioritized data for priority processing, and packets that include requests for reserved connections according to a given reservation protocol. Output queues associated with egress ports of the switch correspond to different priorities associated with received priority packets. An additional output queue is associated with reserved connection data packets. In response to a reserved connection request, the switch determines if sufficient bandwidth exists in the switch to establish a reserved path within the network, and if so, allocates the and width for the reserved connection. In response to each received packet, the switch determines whether the packet is associated with the reserved connection and forwards those packets to the additional output queue on the egress port associated with the reserved connection path for transport to the intended destination.
    • 在能够提供优先通信的网络(例如因特网)中的终端站之间提供预留连接的装置包括与端站的分组通信交换机。 交换机检测并转发包含优先级数据的数据包以进行优先处理,以及根据给定的预留协议包括保留连接请求的数据包。 与交换机的出口端口相关联的输出队列对应于与接收到的优先级分组相关联的不同优先级。 另外的输出队列与保留的连接数据包相关联。 响应于保留的连接请求,交换机确定交换机中是否存在足够的带宽以在网络内建立保留路径,如果是,则分配保留连接的宽度和宽度。 响应于每个接收到的分组,交换机确定分组是否与保留的连接相关联,并将这些分组转发到与预留连接路径相关联的出口端口上的附加输出队列,以便传输到预期目的地。
