Flow synchronization in a receiver
A method for synchronizing a first data stream and a second data stream, at least one stream among the first stream and second stream being received by radiofrequency broadcasting and the other stream being received via an IP network, the first and second streams carrying the same service. The method involves receiving a value of the mean offset between the first stream and the second stream; storing the first stream in a first buffer and storing the second stream in a second buffer; extracting a first extract from the first buffer and a second extract from the second buffer, according to the mean offset value received; comparatively analyzing the first extract and the second extract in order to deduce a value of the actual offset between the first stream and the second stream; synchronizing the first stream and second stream according to the actual offset value obtained.

Determining a part having an anomaly in equipment and initiating an electronic transaction for replacing the part using a three-dimensional (3D) model of the equipment
A system and method for determining a part having an anomaly in equipment and initiating electronic transaction for placing order to replace the part using three-dimensional (3D) model of equipment. The system inspects equipment to identify type of equipment and requests a data storage device storing 3D models of equipment to provide matching 3D models corresponding to equipment identified. The system utilizes various technologies to determine relative location of anomaly indicative of failing/failed part in equipment. The system overlays 3D image map from the 3D model to identify specific part/assembly/subassembly within the 3D model corresponding to the relative location of the anomaly. The system identifies additional parts associated with the failing/failed part as a kit in the 3D image map, and adds the kit to virtual shopping cart for initiating electronic transaction in reference to the kit depicted in the 3D model of equipment for replacement of the failing/failed part.

Compensating for interruptions in a wireless connection
A method of compensating for potential interruptions in a wireless connection (110) over which data is transmitted from a host device (11) to a client device (12) involves determining an expectation of an interruption to the wireless connection (110), setting a second compression level for compressing the data when an interruption is due, the second compression level being set at a higher level than a first compression level normally used for the data, compressing the data at the second compression level, and forwarding the data compressed at the second compression level to a transmitting component (16) for transmittal to the client device (12). The expectation of a potential interruption may be determined by analysing a historical record of previous interruptions to determine a periodicity of the previous interruptions and using the determined periodicity to calculate when a next potential interruption may be expected, or by determining that a buffer used for storing the data prior to transmittal is full, indicative that an interruption has commenced, or by receipt of information from the transmitting component that a potential interruption is expected to occur or has commenced.
System for the reproduction of a multimedia content using an alternative network if poor quality in first network
A method, an apparatus and a system for the reproduction of a specific multimedia content are provided. The method includes the step of acquiring one or more samples of a specific multimedia content reproduced by a mobile multimedia radio/television apparatus, where the specific multimedia content is included in a first signal emitted by a broadcast-type radio/television network, including the further step of determining an identifier of the specific multimedia content and the value of a quality parameter of the first signal. According to the value of the quality parameter of the first signal, further steps include receiving on a multimedia telephone apparatus the specific multimedia content through a second signal emitted by a cellular telephone network, sending the specific multimedia content to one or more multimedia reproduction units included in the mobile multimedia radio/television apparatus.
Encoded output data stream transmission
In some examples, an audio sending device receives a stream of application audio data, encodes the stream of application audio data, and in response to detecting an end of the stream of application audio data, provides pre-encoded filler audio data from a buffer in the audio sending device as an encoded stream of filler audio data. The audio sending device transmits the encoded stream of application audio data and the encoded stream of filler audio data in an encoded output data stream over a transport to an audio receiving device.
