    Abstract: A video display apparatus for composing video signals for a raster scanned display on a line-by-line basis. Objects are stored in a video RAM and are packed in the RAM without regard to their location on the display. A separate dispatch table contains information on each object and commands. A dispatcher operates on this information, allowing lines of data and commands to be extracted from the RAM as each video line is composed in a buffer.

    Abstract: A system and machine-implemented method are described for communicating with a plurality of distributed-input-distributed-output (DIDO) clients. For example, a method according to one embodiment comprises: determining channel state information (CSI) defining a channel state between each of a first plurality of DIDO antennas and each of the DIDO clients; using the CSI to determine distributed-input-distributed-output (DIDO) precoding weights for each of the channels between each of the first plurality of DIDO antennas and the antennas of each of the DIDO clients; using the CSI and DIDO precoding weights to determine link quality metrics defining link quality between each of the first plurality of DIDO antennas and the antennas of each of the DIDO clients; using the link-quality metrics, to determine modulation coding schemes (MCSs) for different DIDO clients; and transmitting precoded data streams from each of the first plurality of DIDO antennas to each of the individual DIDO clients using the determined MCSs for those clients.

    Abstract: Systems and methods are described for wireless backhaul in a multiple antenna system (MAS) with multi-user (MU) transmissions (“MU-MAS”). For example, a multiuser (MU) multiple antenna system (MAS) of one embodiment comprises: one or more centralized units communicatively coupled to multiple distributed transceiver stations via a network; the network consisting of wireline or wireless links or a combination of both, employed as a backhaul communication channel; the centralized unit transforming the N streams of information into M streams of bits, each stream of bits being a combination of some or all N streams of information; the M streams of bits being sent over the network to the distributed transceiver stations; the distributed transceiver stations simultaneously sending the streams of bits over wireless links to at least one client device such that at least one client device receives at least one of the original N streams of information.

    Abstract: A server center for hosting low-latency streaming interactive audio/video (NV) includes a plurality of servers that run one or more applications an inbound routing network that receives packet streams from users via a first network interface and routes the packets to one or more of the servers. The packet streams include user control input. One or more of the servers are operable to compute A/V data responsive to the user control input. A compression unit is coupled to receive the A/V data from the one or more of the servers and output compressed A/V data therefrom. An output routing network that routes the compressed A/V data to each of the users over a corresponding communication channel via a second interface, the compression unit is operable to modify a compression rate responsive to current characteristics of the corresponding communication channel for each user so as to optimize performance of the one or more applications.
