A network device may receive a signal from a headend, wherein a bandwidth of the received signal spans from a low frequency to a high frequency and encompasses a plurality of sub-bands. The network device may determine, based on communication with the headend, whether one of more of the sub-bands residing above a threshold frequency are available for carrying downstream data from the headend to the circuitry. The network device may digitize the signal using an ADC operating at a sampling frequency. The sampling frequency may be configured based on a result of the determining. When the sub-band(s) are available for carrying downstream data from the headend to the network device, the sampling frequency may be set to a relatively high frequency. When the sub-band(s) are not available for carrying downstream data from the headend to the network device, the sampling frequency may be set to a relatively low frequency.

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.

A system includes a satellite receiver and a set top box. The set top box is configured to receive signals from the satellite receiver and output a signal to a display device. The set top box detects whether at least one mobile device is near the set top box and enables a standby mode when no mobile devices are detected.

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.

Provided is a reception device including a first acquisition unit configured to acquire station information regarding a station transmitting a broadcasting wave of broadcasting on an arbitrary segment, a storage unit configured to store the station information, a selection unit configured to select a station transmitting a broadcasting wave that is receivable at a predetermined position as a tunable station to be tuned to using the station information, a specifying unit configured to specify a transmission frequency used at a transmission point of a broadcasting wave of the broadcasting performed by the tunable station using the station information, and a tuning control unit configured to perform tuning control such that a service of the broadcasting performed by the tunable station is tuned to according to the transmission frequency.

Described herein are systems, methods and apparatus for decoding in-band on-channel signals and extracting audio and data signals. Memory requirements are reduced by selectively filtering a bit stream of data in the signal so that services of interest which are encoded therein are processed. A single pool of memory may be shared between physical layer and data link layer processing. Memory in this pool may be allocated dynamically between processing of data at the physical and data link layers. When the available memory is not sufficient to support the required services, the dynamic allocation allows for graceful degradation.
