Method of providing image data based on cloud streaming, and apparatus therefor
The present invention relates to a method of providing image data based on cloud streaming. In particular, the method uses memory space of a terminal, prestores image data in the terminal, captures an execution screen regarding execution of a specific application, extracts video content from the prestored image data based on the captured execution screen and information regarding the execution screen, simultaneously encodes individual items of the extracted video content, and provides the encoded video content to a screen. Thus, according to the present invention, usage of the cloud streaming server and the network may be reduced by an amount commensurate with the resources utilization of the terminal. Network load may also be reduced when a live video or a VOD video is not being watched, and the rich GUI experience may be guaranteed in a standby state.
BROADCAST SIGNAL FRAME GENERATION DEVICE AND BROADCAST SIGNAL FRAME GENERATION METHOD USING BOOTSTRAP INCLUDING SYMBOL FOR SIGNALING BICM MODE OF PREAMBLE AND OFDM PARAMETER TOGETHER
An apparatus and method for broadcast signal frame using a bootstrap including a symbol for signaling a BICM mode and OFDM parameters of a preamble, together are disclosed. An apparatus for generating broadcast signal frame according to an embodiment of the present invention includes a time interleaver configured to generate a time-interleaved signal by performing interleaving on a BICM output signal; and a frame builder configured to generate a broadcast signal frame including a bootstrap and a preamble using the time-interleaved signal. In this case, the bootstrap includes a symbol for signaling a BICM mode and OFDM parameters of L1-Basic of the preamble, together.
RECEPTION APPARATUS AND DATA PROCESSING METHOD
This technology relates to a reception apparatus and a data processing method for easily implementing circuits on the receiving side.
There is provided a reception apparatus including: a demodulation section configured to demodulate packets obtained with respect to each of multiple PLPs included in a broadcast signal; and a processing section configured to process the packets demodulated by the demodulation section. The demodulation section and the processing section are connected with each other via a single interface or interfaces fewer than the number of the PLPs. The demodulation section adds identification information to a specific packet among the packets obtained with respect to each of the PLP, the identification information identifying the PLP to which each of the packets belongs. The processing section identifies the PLP to which belongs each of the packets input from the demodulation section via the single interface or the interfaces fewer than the number of the PLPs, on the basis of the identification information obtained from the specific packet. This technology may be applied to television receivers, for example.

Low power mode in a satellite-based broadcast data service
A satellite system controller for a satellite system can comprise a receiving module, an interval selector, an epoch selector, and a scheduler. The receiving module can receive, from a transmission originator device, a set interval request message requesting the satellite system controller set a transmission interval and an epoch time for a satellite receiver, the transmission interval being an amount of time the satellite receiver is to remain in a sleep mode between expected transmissions and the epoch time being an instant at which the satellite receiver is to expect a satellite transmission. The interval selector can determine, based on the transmission interval, a sleep mode cycle for the satellite receiver. The epoch selector can select the epoch time according to the sleep mode cycle and the scheduler can schedule the satellite transmission with the satellite system at approximately the epoch time and according to the sleep mode cycle.
Receiver
A receiver node for use in a digital broadcast system, comprising a receiver configured to receive a signal containing a service encoded with an error correcting code for decoding and wherein said receiver is further configured to ignore the signal during an ignore period, the node configured to use said error correcting code and the encoded service received outside the ignore period to reconstruct the part of the service ignored by the receiver.
