摘要： A system and a method are disclosed for authenticating a user request to determine whether to optimize content requested by the user based on a user profile, a network provider profile, network conditions and the user's service level with an application requesting the content. A user profile provides, for example a data rate plan subscribed to by the user, the user's device type, etc. Network provider profile provides whether the network provider has subscribed to optimization services. Similarly, user's service level provides whether the application is subscribed to receive optimized data. If the user, the network and the application provide for optimization or if the network is congested or busy, the user is provided with a destination address wherein the user may retrieve optimized content.

摘要： A network-based video encoding and decoding system encodes and decodes remotely displayed user application data on a centralized desktop computer. Remotely displayed user application data are screen captures of a browsing application run by the centralized desktop computer on user's behalf. The encoding system optimizes its encoding performance using back channel information which includes real time network capacity information and decoder feedback. The encoding system consults a back channel information manager to dynamically adjust encoding parameters. Based on the real time network capacity information received, the encoding system adjusts its capturing sampling rate. Based on encoding errors identified by the decoding system, the encoding system selectively re-send previously encoded frames/blocks, or send intra frames on demand to allow the decoding system to correct encoding errors. In response to encoding customization requests from the decoding system, the encoding system adjusts its encoding parameters to meet such requests.

摘要： A memory array comprises N+1 memory elements. N memory elements store data and one or more error check bits respectively derived from the stored data. A separate N+1 memory element stores parity bits generated from the data stored in the N memory elements. These parity bits are stored in. To recover from data errors, data in each N memory element are first checked using their respective error check bits. If faulty data are detected in one of the N memory elements, an exclusive-or operation is performed involving data in the remaining N−1 memory elements and parity bits in the N+1 memory element. This recovers the faulty data in the one memory element.

摘要： Methods and systems for caching packets to improve utilization of packet memory are disclosed. In one method, packets to be written to a packet memory are accumulated in write caches on an egress queue basis. That is, each write cache stores packets corresponding to an egress queue in the system. When one of the queues has a size that corresponds to a burst length of the packet memory, the packets are written from the queue to the packet memory. Packets are read from the packet memory to read caches. Subsequent accesses to packets stored in the read caches avoid the need to access the packet memory.

摘要： A system and a method for communicating video data associated with content across a network are disclosed. A server partitions the content into a plurality of tiles where each tile includes a subset of the content and index data describing a relationship between a tile and one or more adjacent tiles. Each tile is then encoded as a video frame, for example each tile is encoded according to the H.264 standard. The plurality of tiles are then transmitted to a client which combines the plurality of tiles using the index data to locally recreate the content. The client associates a predetermined viewport tile with a client viewport representing the area of the content that is visible in a client display device to allow viewing of the content while tiles not associated with the client viewport are cached to expedite subsequent retrieval.
