摘要:
Procedimiento de emisión y recepción de contenidos audiovisuales en entornos "push" sin canal de retorno en el que un emisor, compuesto por al menos un transpondedor, emite hacia un conjunto de receptores, compuesto cada uno por una pluralidad de sintonizadores, una señal de transporte que comprende al menos un canal de contenidos audiovisuales adaptado para su recepción y reproducción directa en cada receptor mediante la sintonización del transpondedor que emite dicho canal de contenidos audiovisuales por parte de cada receptor, y un canal de datos, asociado a cada canal de contenidos audiovisuales, que comprende al menos un contenido audiovisual, para su posterior grabación en un dispositivo de almacenamiento de cada receptor.
摘要:
A method and system of transmitting video data and multimedia data to a plurality of client radio receivers over an air interface, the method comprising transmitting video data to a plurality of client radio receivers simultaneously using an adaptive encoding / transcoding scheme; and updating the adaptive encoding / transcoding scheme in dependence upon received feedback data. A system and method is also described that includes estimating channel states and distortion levels for a plurality of transmission modes, and then selecting that transmission mode for subsequent data transmission that has the lowest distortion level. Control data items can also be extracted from the first data stream to produce a multimedia data stream and a control data stream and the multimedia data stream is transmitted over a first channel; and the control data stream is transmitted over a second channel. The received data stream may be put into a plurality of multimedia slices having a predetermined slice size; and encoded into first data packets of a first predetermined size; which in turn are divided into respective integral second data packets of a second predetermined size and which are aggregated into a stream of third data packets of a third predetermined size.

Ein Verfahren und eine Sendevorrichtung zur Übertragung von Programm- bzw. Service-Daten und von Codierungs-Daten zur Codierung der Programm- bzw. Service-Daten in periodisch wiederholten, zum jeweiligen Programm bzw. Service (A, B) gehörigen Burstintervallen in einem digitalen Fernseh-Übertragungssystem weist ein einstellbares Verhältnis der Anzahl der zum jeweiligen Programm bzw. Service (A, B) gehörigen Programm- bzw. Service-Daten zur Anzahl der zugehörigen Codierungs-Daten, zu den einzelnen Programmen bzw. Services (A, B) jeweils gehörigen Programm- bzw. Service-Daten, die jeweils in mehrere Untermengen von Programm- bzw. Service-Daten einteilbar sind, und für jede Untermenge jeweils ein unterschiedlich einstellbares Verhältnis der Anzahl von Programm- bzw. Service-Daten zur Anzahl der zugehörigen Codierungs-Daten bei konstanter Länge ( Δt A ; Δt A ', Δt A "; Δt A1 , Δt A2 , Δt A3 , Δt A4 ) des zum jeweiligen Programm bzw. Service (A, B) gehörigen Burstintervalls auf.

Systems and methods for using broadcast bandwidth for updating firmware of digital televisions may include identifying a portion of unused bandwidth corresponding to a television station; selecting at least one update module, the update module comprising an update to firmware of a digital television; transmitting, via the unused bandwidth of the television station, the at least one update module; and receiving by a digital television, the at least one update module.
摘要:
A system and a method for providing personalized data contents for a digital broadcasting and a computer-readable medium having thereon a program performing a function embodying the same are disclosed. In accordance with the present invention, a data content is configured to include multiple scenarios, a personalized data content is provided to a viewer based on the scenario suitable for the viewer of the multiple scenarios when received by a receiver, and a communication load due to a transmission of the data contents is minimized while providing the personalized data content to the viewer.
摘要:
The present invention is suitable for use in a communications system that transmits a transport stream, such as an MPEG stream. The present invention addresses the need of generating a valid value for a duplicated packet in the transport stream. A first embodiment of the present invention interpolates between a PCR value in the duplicated packet and the PCR value in the next PCR packet. A second embodiment of the present invention copies an original packet along with its PCR value into a duplicate packet and a PCR-bearing packet. Subsequently, the present invention interpolates a new value for the original packet based on the original value in the duplicated PCR-bearing packet and the previous value in a PCR-bearing packet.
