20080260086 | CARRIER SYNCHRONIZING CIRCUIT AND CARRIER SYNCHRONIZING METHOD - Disclosed herein is a carrier synchronizing circuit including at least frequency synchronizing means and phase synchronizing means. The phase synchronizing means includes residual frequency error detecting means for detecting a residual frequency error after a frequency synchronizing process by the frequency synchronizing means and supplying the residual frequency error to the frequency synchronizing means, and the frequency synchronizing means performs frequency pull-in for the residual frequency error supplied from the residual frequency error detecting means after first timing. | 10-23-2008 |
20080270876 | Decoding Apparatus, Decoding Method, and Decoding Program - A decoding apparatus includes a memory and a receiving unit and is adapted to decode data in units of codewords each including a parity part. The memory has a storage capacity capable of storing at least data with a length equal to the length of one codeword. The receiving unit receives, as received values, elements of a codeword in a bit-interleaved form, performs bit deinterleaving and parity permutating on the received values, and stores the resultant received values in the memory. | 10-30-2008 |
20130308655 | TRANSMITTING APPARATUS, TRANSMITTING METHOD, RECEIVING APPARATUS, RECEIVING METHOD, PROGRAM, AND ELECTRONIC APPARATUS - Disclosed herein is a transmitting apparatus, including: a stream inputting portion inputting plural transport streams; an information adding portion adding additional information containing therein a stream identifier used to identify at least corresponding transport stream to respective transport stream packets of the plural transport streams thus inputted; a stream synthesizing portion synthesizing the plural transport streams in which the additional information is added to each of the transport stream packets, thereby obtaining one stream; and a stream transmitting portion transmitting the resulting one stream to an external apparatus. The information adding portion adds the additional information forward, backward or midway with respect to each of the transport stream packets. | 11-21-2013 |
20140254610 | ELECTRONIC APPARATUS, STREAM TRANSMISSION AND RECEPTION METHOD OF ELECTRONIC APPARATUS, PROGRAM, HOST DEVICE, AND STREAM TRANSMISSION AND RECEPTION METHOD OF HOST DEVICE - Provided is an electronic apparatus including a synthesized stream creation unit, a stream transmission unit, a process information retaining unit, a count information addition unit, a stream reception unit, and a processing unit. | 09-11-2014 |
20140267929 | CHANNEL SCAN DEVICE AND METHOD, AND PROGRAM - The present technique relates to a channel scan device and method, and a program configured so that high-speed channel scan is enabled. | 09-18-2014 |
20150022263 | DEMODULATION DEVICE, DEMODULATION METHOD AND PROGRAM - The present technique relates to a demodulation device, a demodulation method and a program capable of realizing a demodulation process at a rate equivalent to a case where I and Q channel signals are not inverted, even when the I and Q channel signals are inverted. A frequency correction unit establishes synchronization of a frequency and clock based on a signal from a frequency synchronization unit. A channel inversion detection unit of a frame synchronization unit detects presence or absence of inversion of I and Q channel signals, and supplies, as a detection result, a channel inversion detection result to the channel inversion control unit. The channel inversion control unit switches the I and Q channel signals if the inversion has occurred, based on the channel inversion detection result. This technique can be applied to a demodulation device. | 01-22-2015 |
20150131746 | SIGNAL PROCESSING DEVICE AND SIGNAL PROCESSING METHOD - Provided is a signal processing device, including a clock width calculation unit configured to calculate a clock width corresponding to a data rate of a valid section in which a transport stream (TS) packet exists, and a generation unit configured to generate a clock signal whose period is the clock width calculated in the clock width calculation unit and to output the clock signal as a shaped TS clock signal, the shaped TS clock signal being a TS clock signal of the TS packet to which shaping has been performed. | 05-14-2015 |
20150139220 | SIGNAL PROCESSING DEVICE AND SIGNAL PROCESSING METHOD - There is provided a signal processing device including a selection unit that selects and outputs one clock serving as a transport stream (TS) clock, which represents timing of data of a TS, among a plurality of clocks with frequencies not less than a serial rate which is a data rate at which the TS included in a radio frequency (RF) signal is output in a serial manner. | 05-21-2015 |
