Providing Television Broadcasts over a Managed Network and Interactive Content over an Unmanaged Network to a Client Device

A client device receives a broadcast content signal containing an interactive identifier over a managed network at a client device. The interactive identifier may be a trigger that is included in a header or embedded within the digital video data. The trigger may have a temporal component, wherein the trigger can expire after a certain period of time. In response to identification of the trigger, the client device sends a user request for interactive content over an unmanaged network. For example, the managed network may be a one-way satellite television network, IP-television network or cable television network and the unmanaged network may be the Internet. The client device switches between receiving data from the managed network to receiving data from the unmanaged network.

Adaptive code rate video transmission method and system based on reinforced learning

The invention discloses an adaptive code rate video transmission method and an adaptive code rate video transmission system based on reinforced learning. The method comprises the steps of inputting astate space corresponding to a video block needing to be downloaded into a code rate prediction neural network, and outputting a code rate strategy by the code rate prediction neural network; downloading the video block needing to be downloaded according to the code rate strategy output by the code rate prediction neural network; after each video block is completely downloaded, computing a video playing quality index corresponding to each video block and returning the video playing quality index back to the code rate prediction neural network; and performing training by the code rate prediction neural network according to the returned video playing quality index and the state space corresponding to the completely downloaded video block. According to the method and the system provided by the invention, the algorithm well adapts to multiple different network conditions while the quality of service is improved, the labor time cost of rule setting and parameter optimization is greatly reduced, the efficiency problem caused by artificial feature selection and rule setting is avoided, and the video quality experience is also greatly improved while the configuration and debug time is saved.

Managing multiple dynamic media streams

A coordinated adaptive streaming system provides a level of intelligence between adaptive streaming heuristics applied to multiple multi-bitrate streams playing on a client computer at the same time. The system receives a media event that includes multiple multi-bitrate streams and plays two or more of the streams. Each stream registers with the coordinated adaptive streaming system so that the system is aware of each of the streams. The system receives a priority indication from each stream that indicates the priority of the stream relative to other streams associated with the media event. The system uses the received priority indications to make adaptive streaming decisions. Thus, the coordinated adaptive streaming system provides playback that more closely aligns with a user's priorities and provides a higher quality experience to a user viewing multiple concurrent media streams.

Intelligent wifi-offloading for next-generation mobile networks

A system for traffic management between a WiFi network and an LTE network that includes a network interface assignment module for determining from an operator side of the WiFi network and the LTE network a set of WiFi Access Points (APs) and LTE base stations for each user that provides a least a highest quality of experience for each of the users using input strength for all users to potential WiFi access points and LTE base stations. The system may further include an interface switching service (ISS) module that includes a control logic and a network HTTP proxy for delivering network switching instructions to devices of users. The control logic receiving instructions from the NIA module and sending signal to the devices of the users to switch from WIFI and LTE networks through the LTE network based upon signal strength of the users.

A method and tool for detecting and correcting chromaticity and brightness consistency of an intelligent lamp

The invention discloses a method and tool for detecting and correcting chromaticity and brightness consistency of an intelligent lamp, relates to the field of intelligent lamps. all the intelligent lamps in the same batch are detected and corrected in batches, and identification information on the intelligent lamps and on a test tool is read by using a preprocessing code reading unit. The lamp driving unit drives the LED lamp bead group in the intelligent lamp to be detected to emit light, and the chromaticity and brightness of the intelligent lamp are acquired and measured by the chromaticityand brightness acquisition unit; And the correction unit calculates correction parameters and writes the correction parameters into the intelligent lamp. The chromaticity and the brightness of the intelligent lamp are corrected, so that the performance of the same type of lamp is consistent; Through a data wireless transmission mode, the problem that the intelligent lamp cannot be effectively tested or is not easy to effectively test before finished products are solved; The test tool is equally divided into a plurality of areas, so that light pollution between lamps can be prevented to the maximum extent.

Improvements in controlling internal combustion engine emissions

Disclosed is an engine control method for a vehicle having an electronically controlled drive line such as an electronic multi-speed transmission with an automatic gear box. The method of operation comprises the steps of turning on the engine and then keeping the engine revs high whilst an engine is idling and not connected to a transmission system, for instance whilst the neutral position is selected. The high idle speed is maintained on sensing that the gear select is moved from neutral to drive and the controller delays dropping the engine idle speed and engaging the drive line until the wheel brake is removed. Sensors may be provided to detect release of the wheel brakes and gear position. The method is used to provide a high engine operating speed on engine start up and / or warm up to ensure that the engine heats up rapidly so that the hot exhaust fumes can be used to heat a catalytic convertor to bring it to its active operating temperature.

Method for transmitting data in a discontinuous coverage radio network

To mash coverage discontinuities, e.g. of high and low bit rate zones, when transmitting especially multimedia data to a terminal (209), it is proposed to store the data of a multimedia data stream's basic flow to a basic cache memory (315) with higher priority than storing the data of at least one enhancement flow of a multimedia data stream to at least one enhancement cache memory (317, 319), at least when said terminal (209) is likely to leave a high bit rate zone. The invention addresses as well a multimedia module (205), a terminal (209) and a computer program product adapted to this handling of multimedia streams.
