摘要:
A method is described for streaming video data within a network, wherein the video data includes a sequence of frames. The method includes encoding the sequence of frames and generating a plurality of substreams from the encoded frames in this embodiment. Each of the plurality of substreams is assigned an identifier, and each substream includes a common encoded frame and a non-overlapping portion of the encoded sequence. The non-overlapping portion of the encoded sequence of each substream is selected from the encoded frames based on the identifier of the respective substream. The method also includes transmitting the plurality of substreams to a receiver in an embodiment.

A method for streaming audio data in a network, the audio data having a sequence of samples, includes encoding the sequence of samples into a plurality of coded base bitstreams, generating a plurality of enhancement streams, and transmitting the coded base bitstreams and the enhancement bitstreams to a receiver for decoding. Each of the enhancement bitstreams is generated from one of a plurality of non-overlapping portions of the sequence of samples.

A system for enabling streaming video to a mobile client includes a plurality of fixed node peers linked to the mobile client via one or more networks as well as a video source linked to fixed node peers and configured to provide streaming video data representing a video presentation to each of the fixed node peers. A decoder assembly associated with each of the fixed node peers is configured to decode the streaming video data and to transcode a portion of the decoded streaming video data for transmission to the mobile client. A video substream manager and interleaver on the mobile client is provided for receiving the transcoded output of the decoder assemblies of the fixed node peers and reconstructing the video presentation on a screen of the mobile client.

A method of tracking an inventory of objects via a mobile communications device includes acquiring an image of one or more of the objects via the mobile communications device, which also collects a location of the mobile communications device while acquiring the image of the one or more of the objects. The location and image are transferred from the mobile communications device to a remote server via a wireless network, such that the one or more of the objects are identified at the server based on the image, and the location and identity of the one or more objects are stored on a database associated with the server.

A method for managing TCP flows in a mobile device adapted to connect to two or more wireless network types includes enabling connection to a number of networks of different types at the mobile device and executing a plurality of Internet-enabled applications on the mobile device. Each such application forms an existing TCP connection over a first one of the wireless networks. The routing table is modified such that any additional TCP connection will be created on a second one of the wireless networks. The device determines that a termination condition has occurred and in response to determining that the termination condition has occurred, renders an interface on the mobile device to the first one of the wireless networks inoperative.

A method for navigation based on a cellid-aided positioning system includes: determining, at a cellid-aided positioning system-compatible device, that a user has moved through a sequence of cellids, wherein moving through a sequence of cellids comprises moving from a first region corresponding to a first cellid to a second region corresponding to a second cellid; accessing previously stored route information corresponding to the sequence of cellids, wherein the previously stored route information includes previously recorded sequences of cellids and global positioning system (GPS) information; estimating a current position of the user based on the previously stored route information; and displaying the current position of the user.

An error correction code includes a separate error code portion for each of two or more separate burst erasure durations (or burst error durations). For each burst erasure duration, the code can be employed to recover from the burst erasure with a different delay time. Each error code portion has a particular parameter for burst duration (B) and delay (T), meaning that the code can be used to recover from a burst erasure of duration B with delay T. Each error code portion is based on separating the source symbols into sub-symbols and diagonally interleaving the sub-symbols based on the (B,T) parameters for the error code portion. Accordingly, different burst erasures are recovered from with different delays.
