System and method for large data transmission in digital radio broadcasting
Large data transmission in digital radio broadcasting system and method are disclosed. A first channel information of tuned frequency indicates the availability of the data distribution table. Second channel information contains the data distribution info table (list of frequencies mapped to data chunk identifiers). Data chunks have a unique id. Digital broadcast radio receiver receives data distribution tables and parses through the currently tuned frequencies data distribution table. The receiver has information on how to collect the distributed data. Receiver uses its primary tuner to receive the data chunks in the current tuned frequency. Rest of the data chunks are collected by the background tuners in a parallel fashion by tuning to required frequencies. Once all chunks are collected, data file is reconstructed and available for presentation to the user.
Multi-portion radio transmissions
Techniques are disclosed relating to generating and receiving radio frames with multiple portions that have different target geographic areas. A data frame may include a first partition that includes a physical layer encoding of first data to be transmitted in a first geographic area, where the first geographic area is defined by a first threshold distance from the one or more transmitters. The data frame may include a second that includes a physical layer encoding of second data to be transmitted in a second geographic area, where the second geographic area is defined by a second, greater threshold distance from the one or more transmitters.

System and method for improving the graphics performance of hosted applications
One or more hardware components identify a bottleneck stage within a processor pipeline that processes frames of a video stream. The bottleneck stage has a first clock. An upstream stage receives a feedback signal from the bottleneck stage. The upstream stage has a second clock and the feedback signal includes information as to time required by the bottleneck stage to operate on data and information as to time the data spent queued. The upstream stage adjusts the speed at which the upstream stage operates and queues data to approximate the speed at which the bottleneck stage is operating and queuing data.

Channel bonding in an adaptive coding and modulation mode
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for channel bonding in an adaptive coding and modulation mode. In some implementations, a system receives packets of a data stream for transmission in a satellite communications system. The system determines a modulation and coding arrangement for the received packets. The system generates code blocks that include data from the packets of the data stream. The system assigns the generated code blocks for transmission on different carriers. One or more of the different carriers is operated in an adaptive coding and modulation mode to support multiple modulation and coding arrangements within a single carrier. The system transmits the code blocks on the different carriers using the determined one or more modulation and coding arrangements.
Methods, systems and devices of approximately synchronous broadcast of aircrafts
This invention is related to automatic monitoring and collaboration among aircrafts. Specifically, an aircraft receives the current and future state of adjacent aircrafts by broadcast, then analyzes the start time of collaborative tasks. Base on the start time and prior knowledge, it adjusts automatically the prediction accuracy requirements of its future states, the check interval of predicted state errors and the minimum check interval. And it makes a new prediction and broadcasts new future states based on the check results of prediction errors. In the invention, an aircraft does not periodically broadcast its states, but broadcasts irregularly its future states according to its current tasks, its states and surrounding environment. The invention guarantees that collaborative tasks can be can be correctly carried out among aircrafts while it reduces the bandwidth requirement of wireless communication. It provides guarantee of high density flight and collaboration among many aircrafts.
Broadcast Signal Detecting Method and Broadcast Signal Detecting Device
If reception quality of a broadcast signal of a first frequency received by a tuner satisfies setting conditions, the frequency received by the tuner is changed from the first frequency to a second frequency. It is evaluated whether or not the amount of offset between a reference frequency and the frequency of the signal, which is generated by converting the broadcast signal of the second frequency received by the tuner into an intermediate frequency is within a predetermined range. If the offset between the reference frequency and the frequency of the intermediate frequency signal is within the predetermined range, the data included in the broadcast signal of the first frequency is acquired by a demodulating the broadcast signal of the first frequency. It is evaluated whether or not the broadcast signal of the first frequency is a broadcast signal of a broadcasting station based on the acquired data.
