A system and method that facilitate efficient use of 3G high-speed data networks while providing for personalized audio content selection and coordinated distribution of selected content are disclosed. The invention categorizes audio content to be delivered over wireless networks such that the categories correspond to a different delivery priority. In an illustrative three-category implementation, category 1 content has the highest delivery priority for delivery as soon as possible, category 2 content has the next highest delivery priority for delivery, and category 3 content, such as music, audio books and so on, has the least urgent delivery priority. The categories are used to coordinate audio content delivery to efficiently use available bandwidth and network resources by delivering content at off-peak times. The invention also allows the downloading process to be interruptible such that it can be resumed at about the point of an interruption to conserve resources.

A coding efficiency increase is achieved by using a common signalization within the bitstream with regard to activation of merging and activation of the skip mode. One possible state of one or more syntax elements within the bitstream may signalize for a current sample set of a picture that the sample set is to be merged and has no prediction residual encoded and inserted into the bitstream. A common flag may signalize whether the coding parameters associated with a current sample set are to be set according to a merge candidate or to be retrieved from the bitstream, and whether the current sample set of the picture is to be reconstructed based on a prediction signal depending on the coding parameters associated with the current sample set, without any residual data, or to be reconstructed by refining the prediction signal depending on the coding parameters associated with the current sample set by means of residual data within the bitstream.

Some embodiments provide an end-to-end federated CDN solution that assimilates a transparent caching server that is operated by a transparent caching server operator into a CDN that independently operates CDN caching servers. Specifically, the logs from the transparent caching server are assimilated into the CDN by aggregating the logs from the transparent caching server and processing the transparent caching server logs to identify network usage for content of a CDN content provider customer that is delivered by the transparent caching server. The network usage is then combined with the network usage that tracked by the CDN caching servers in order to provide comprehensive report metrics for the content provider customer and to bill the content provider customer for all network usage related to delivering the content provider customer's content irrespective of whether the content was delivered by a transparent caching server or a CDN caching server.

A load condition of a cell is determined without having to measure one or more radio parameters pertaining to the cell load, e.g., interference level. Based upon that determined load condition, a traffic condition of the cell may then be regulated, e.g., admission and / or congestion control, transmit power control, etc. The load condition is determined simply and accurately by observing the value (absolute or weighted) of transmit power control commands issued in the cell over a particular time period. To identify potential “false alarms” of increased cell loads, a radio parameter associated with another frequency band in another cellular system that impacts the load condition of the cell in the current cellular system is measured. A traffic condition in that cell is regulated based upon the determined load condition in the cell taking into account the measured radio parameter.

Some embodiments provide a proprietary 64-bit consistent distribution scheme that preserves the efficiencies of CARP while providing a significantly more balanced distribution of requests that is on par with schemes reliant on computationally expensive cryptographic hashes. The scheme performs hashing of requested URLs and identifiers of available servers over a 64-bit space while optimizing the hashing to remove computationally expensive operations. Some embodiments provide a variant of the scheme to provide a differentiated distribution on the basis of one or more differentiating factors. A first variant utilizes load factor values to adjust the resulting hashes and to produce a first distribution of differentiated content that varies from a second distribution of undifferentiated content. A second variant identifies requests for differentiated content from requests for undifferentiated content and utilizes a first scheme to distribute the differentiated content and a second altered scheme to distribute the undifferentiated content.
