摘要:
Systems, devices and methods are described to obtain a lower-quality replacement when the reception of a direct broadcast satellite (DBS) or other broadcast television signal becomes weak or unavailable due to weather, maintenance or other circumstances. The received broadcast television signal is monitored by a receiver, antenna, outdoor unit or the like. When the received broadcast signal becomes weak or unavailable, the television receiver obtains a lower quality replacement for received broadcast signal from a network service or other alternate source to thereby continue the playback of the television program. Lower quality alternatives may include lower quality video streams, audio streams, text tickers, web pages or the like.
摘要:
A method is presented for notifying a user of a broadcast communication channel problem. At a broadcast distribution facility, a problem involving a first broadcast communication channel from the broadcast distribution facility to a broadcast communication receiver associated with the user is detected. A cause of the problem is ascertained at the facility. The broadcast distribution facility then relays an indication of the cause of the problem to the receiver over a second broadcast communication channel from the facility to the receiver. The receiver informs the user of the cause of the problem.

A display control apparatus includes a reception frequency acquisition unit configured to acquire a reception frequency, a reception quality acquisition unit configured to acquire reception quality, a first data acquisition unit configured to acquire first data at a reception frequency, a second data acquisition unit configured to acquire second data from a signal of a reception frequency, a display control unit configured to control display of first data until acquisition of second data after acquisition of first data, and a display unit configured to display first data and/or second data in accordance with control of a display control unit.
摘要:
A system, apparatus and a method for transmitting continuous audio data configured to mitigate data discontinuities in a receiving device. The method may mitigate data discontinuities by transmitting a continuous stream of audio data that has reduced changes to the audio data characteristics. The method may transmit filler audio data when no application audio data is available. The application audio data and the filler audio data are processed to reduce changes to the audio data characteristics in each stream.
摘要:
A wireless communication system is enhanced to allow for low-latency channel surfing and to enable a user to quickly see the content carried over a selected channel while searching channels for desired content. The techniques for reducing the channel change latency may be implemented in a transmitter, receiver, or in a combination of transmitter and receiver. The wireless communication system is optionally a DVB-H communication system. The transmitter may generate and transmit one or more auxiliary channels, where each auxiliary channel contains reduced resolution content corresponding to one or more channels. The receiver may process the one or more auxiliary channels to present the reduced resolution content while processing the full resolution channel for display. The receiver caches portions of content from one or more non-selected channels and presents the cached content when the channel is selected while concurrently searching and processing the full resolution channel content.
摘要:
A method and apparatus for improving the reception of digitally modulated signals. A main signal and a supplemental signal are provided in the transmitter. The signals may be substantially identical except that the supplemental signal is advanced in time with respect to the main signal. The main and supplemental signals are sent from the transmitter to the receiver modulated on a signal. At the receiver, the supplemental signal is stored in a buffer. If the main signal is undesirably changed during transmission, corresponding portions of the supplement signal are substituted for the undesired portions of the main signal.
摘要:
In some examples, a first 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 first device as an encoded stream of filler audio data. The first 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 a second device.
摘要:
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.
摘要:
An apparatus is provided which has a receiver configured to receive a media stream from a broadcast source and a circuitry. The circuitry is configured to obtain a specific media content included in the received media stream from a second source.
摘要:
A method and an apparatus for transmitting broadcast signals thereof are disclosed. The apparatus for transmitting broadcast signals, the apparatus comprises an encoder to encode service data corresponding to each of a plurality of physical paths, a time interleaver to the encoded service data in each physical path by a TI (Time Interleaving) block, wherein at least one virtual FEC block is ahead of FEC blocks in at least one TI block, wherein each TI block includes a variable number of FEC blocks of the encoded service data, wherein a number of the at least one virtual FEC block is defined based on a maximum number of FEC blocks of a TI block, a frame builder to build at least one signal frame including the time interleaved DP data, a modulator to modulate data in the built at least one signal frame by an OFDM (Orthogonal Frequency Division Multiplex) scheme and a transmitter to transmit the broadcast signals having the modulated data.
