摘要： According to various aspects, methods for multicasting in wireless networks may include one or more client devices sending requests for delivery of application data packets to a network access station. The requests may include a multicast address and QoS attributes. The network access station may create a multicast schedule which coordinates the multicast deliver with power saving protocols of the client device so that the client devices will be awake when the multicast occurs. The client devices may also instigate removal of a multicast schedule when the application data packets are received or no longer needed by sending schedule deletion requests to the access station. When a deletion requests is received from the last client device associate with a multicast schedule, the schedule may be removed. Additional embodiments and implementations are also disclosed.

摘要： A base station may organize poll groups into groups having similar predicted durations of subsequent responses. In one embodiment predicted durations may be provided by the devices that are to be polled. In another embodiment the predicted durations may be based on past responses from the devices that are to be polled.

摘要： A source application executed within a source device may packetize and send source data over a link to a destination application executed within a destination device. In various embodiments, clock recovery processes are performed in conjunction with the destination application in order to synchronize the rates of source data production and consumption (e.g., playback). To facilitate the clock recovery process, a transport delay is calculated based on the difference between a source MAC-layer timestamp and a destination MAC-layer timestamp that envelop portions of the link that include variable delay elements. The transport delay is used by the clock recovery process to adjust a source application-layer timestamp, in one embodiment. In another embodiment, the transport delay is used by the destination device to impart a fixed cumulative transport delay on the source data before it is delivered to the destination application.

摘要： Videogame systems and methods are provided to enhance the capability of the videogame system controller and data storage to provide graphic character element storage and processing. A display list technology utilizes an intentionally generated, location-specific vertical interrupt to implement a routine to modify or to alter existing graphical character elements. A second technique involves the definition of a small portion of the graphics map which is displayed differently than the balance of the graphics map because the stored priority bit is expressed in the defined area, but suppressed and replaced in all other areas. The third technique employs a virtual character element library to map the character elements appearing on the display, and recognizes available space within the video random access memory character element storage to provide a dynamic memory space.
