A mobile payment platform and service provides a fast, easy way to make payments by users of mobile devices. The platform also interfaces with nonmobile channels and devices such as e-mail, instant messenger, and Web. In an implementation, funds are accessed from an account holder's mobile device such as a mobile phone or a personal digital assistant to make or receive payments. Financial transactions can be conducted on a person-to-person (P2P) or person-to-merchant (P2M) basis where each party is identified by a unique indicator such as a telephone number or bar code. Transactions can be requested through any number of means including SMS messaging, Web, e-mail, instant messenger, a mobile client application, an instant messaging plug-in application or “widget.” The mobile client application, resident on the mobile device, simplifies access and performing financial transactions in a fast, secure manner.

A system and process for controlling the coding bit rate of streaming media data is presented where a server streams data that exhibits one of a number of coding bit rates supported by the server. Initially, the server chooses the coding bit rate. However, after this startup period, the client provides coding bit rate requests. The server transmits the streaming media data at the most appropriate supported coding bit rate closest to the rate requested. The coding bit rates requested are those estimated to provide a high quality playback of the streaming data while still keeping a decoder buffer of the client filled to a desired level. A leaky bucket model is incorporated so that the changes in buffer duration due to natural variation in the instantaneous coding bit rate are not mistaken for changes in buffer duration due to network congestion.

Decoder retrieval timing information, ROI information and tile identification information are conveyed within a video data stream at a level which allows for an easy access by network entities such as MANEs or decoder. In order to reach such a level, information of such types are conveyed within a video data stream by way of packets interspersed into packets of access units of a video data stream. In accordance with an embodiment, the interspersed packets are of a removable packet type, i.e. the removal of these interspersed packets maintains the decoder's ability to completely recover the video content conveyed via the video data stream.

The present invention relates to an architecture for stack robust fine granularity scalability (SRFGS), more particularly, SRFGS providing simultaneously temporal scalability and SNR scalability. SRFGS first simplifies the RFGS temporal prediction architecture and then generalizes the prediction concept as the following: the quantization error of the previous layer can be inter-predicted by the reconstructed image in the previous time instance of the same layer. With this concept, the RFGS architecture can be extended to multiple layers that forming a stack to improve the temporal prediction efficiency. SRFGS can be optimized at several operating points to fit the requirements of various applications while the fine granularity and error robustness of RFGS are still remained. The experiment results show that SRFGS can improve the performance of RFGS by 0.4 to 3.0 dB in PSNR.

The efficiency of transmitting lower priority data traffic along with higher priority traffic is improved by segmenting a data packet in such a way so as to reduce transmission delay of the higher priority traffic. The data packet is segmented so that all its segments, including the last segment, are approximately the same size. The segment size is set smaller than a maximum permitted segment size. Indeed, it is desirable (though not necessary) to set the segment size as small as design parameters, (e.g., minimize segment header overhead), allow in order to reduce transmission delay of the higher priority traffic. Because the last segment is set at the same size or a larger size than the other segments, delay in transmitting the data packet is also reduced. The last segment may be sized as large as practical to minimize the transmission delay of the data packet. Once segmented, the data packet segments are transmitted along with the higher priority traffic.

If one or two bits of data error occurs, the data error is corrected and correct data is outputted; if two bits or testable more than three bits of data error occurs, the information that non-correctable error occurs is prompted. The method has strong error correction ability, simple operation, and one-bit or two-bit error of memory caused by single event effect is effectively corrected.
