    Abstract: The present invention relates to the domain of video equipment. It concerns more specifically a transmission device able to transmit packets, said device comprising the means to extract image ticks from a synchronisation signal, the means to initialise an image counter from said image ticks, the means to initialise a CPT— PCR counter every “m” passage through zero of the image counter, CPT_PCR producing counting ramps CSE_PCR with a range M, the means to sample the counting ramps CSE_PCR every Tech period, where Tech is from a time base synchronised on all the stations of said network, and the means to transmit packets comprising a PCRe sample of the CSE_PCR counting ramp. According to the invention, it also comprises the means to insert in the packet:—an Num index identifying the CSE_PCR counting ramp from which the PCRe sample is realised, and—a time label Datejnit indicating a CSE_PCR counting ramp timestamp passage through a reference value PCR_REF comprised between 0 and M-1.

    Abstract: Disclosed are a system and method for providing digital multimedia broadcasting confinement service. The system includes: a relay center side system, which is adopted to the relay center, according to the relay center side packet identification description (PID) key, for modifying the PID of transport stream and generating the distorted program specific information (PSI); and a terminal side system, which is adopted to the DMB terminal, according to the terminal side PID key, for recovering the distorted PSI of the transport stream received from the relay center and decoding it. The method includes the steps of: identifying whether the actual PID of the TS is consistent when the TS is demultiplexed by audio/video PID acquired through the program map table (PMT) analysis of the TS; generating a preset alarm signal; modifying the PID of the audio/video data in the PMT according to the terminal side PID; and demultiplexing the TS according to the modified PID value.

    Abstract: There is provided a digital broadcast receiver that can readily cope with a change in a time lag between simultaneous broadcasts and opening of a new broadcast station and that enables smooth switching between the simultaneous broadcasts without addition of devices entailing performance of enormous amounts of processing. A characteristic showing that a coding rate increases when a large difference arises between a current frame and a preceding frame of a video signal is utilized for MPEG2 and MPEG4-AVC standards employed as schemes for coding a video signal in a ground digital broadcast. A per-frame coding rate of first broadcast coded video data and a per-frame coding rate of second broadcast coded video data are ascertained. A lag between an output time of the first broadcast and an output time of the second broadcast is detected from time shifts in the thus-ascertained coding rates and a lag between internal clock signals. The output time of the first broadcast video frame and the output time of the first broadcast audio frame are delayed by an amount corresponding to the output time lag. Either the first broadcast or the second broadcast is selected according to predetermined conditions, and the thus-selected broadcast is displayed on a display.

    Abstract: A transport stream (TS) demultiplexer has a TS input switch unit and an output switch unit, whereby inputs and outputs can be selected as desired, external output can be easily changed by changing selected information of the TS input switch unit and the output switch unit, without changing inputs. Therefore, the TS demultiplexer receives a plurality of TSs such as MPEG-2 TSs and DSS TSs, and can selectively demultiplex the TSs, and particularly, the TS demultiplexer can store the TSs in a storage medium such as a hard disc drive, or it can easily transmit the TS data over an IEEE1394 bus or a PCI bus.
