摘要:
A method and system for maintaining the quality of video transported over wireless channels uses a transcoder to modify and maintain the optical resilience of an encoded bitstream. The transcoder increases the spatial resilience by reducing the number of blocks per slice, and increases the temporal resilience by increasing the proportion of I-blocks that are transmitted in each frame. Also, the transcoder maintains the same input bit rate by dropping less significant coefficients as it increases resilience. The transcoder of the present invention maintains the resilience at an optimal level to accommodate the prevailing channel conditions as measured by the BER of the wireless channel. Rate distortion theory is applied to determine the optimal allocation of bit rate among spatial resilience, temporal resilience and source rate, where it is has been found that the optimal allocation of the present invention (which occurs in near-real time) provides nearly the same result as doing an exhaustive search.

A system that incorporates teachings of the present disclosure may include, for example, a computer-readable storage medium in a communication device having computer instructions to establish communications with a cellular base station, generate a message request, and transmit to an authentication device by way of the cellular base station the message request. The computer-readable storage medium can also have computer instructions to receive from the authentication device by way of the cellular base station a message response, authenticate the message response, and determine from the authenticated message response whether the cellular base station is an approved network element of a cellular communication system. Other embodiments are disclosed.
摘要:
Devices, systems, and methods are disclosed which relate to devices utilizing time-sensitive memory storage. The time-sensitive memory storage acts as normal device memory, allowing the user of the device to store files or other data to it; however the information stored on the time-sensitive memory storage is automatically erased, based on some storage time period. A limited amount of persistent storage is used for names and message headers.

摘要:
System(s) and method(s) are provided to route data within a network of content with specific service constraints to mobile devices. A mobile network management component receives an identifier (ID) of a base station that serves a mobile device that originates a request for data, and relays the ID to a network platform that administers content. A mapping that associates one or more base stations with a deployed content node and the received ID are utilized to identify a content node to serve the request for data via the base station. The received request for data is directed to the identified content node. A service constraint configuration can be allocated for exchange of payload data between the mobile device and the network platform. For a request to consume data and a request to supply data, identified content node delivers data and receives data, respectively, in accordance with the service constraint allocation.
