摘要： A relay device employs a control system which notifies control data indicating its own specification to transmitting equipment to receive data in a form matching to its own specification and acquires control data D13 from receiving equipment employing the control system and connected to a latter stage. The relay device determines whether its own specification is in a higher order or not in comparison a specification indicated by the control data D13 with its own specification, and if it is determined that its own specification is in the higher order, rewrites the control data D13 from the receiving equipment by its own control data D12 to notify it to the transmitting equipment. Thereby, the relay device can reproduce the data from the transmitting equipment in accordance with its own specification. At this time, since the relay device converts the received data from the transmitting equipment to transmit it, even the receiving equipment can reproduce it in accordance with an appropriate specification.

摘要： Systems and methods for resolving a partial topology are disclosed. In one embodiment a media engine includes a topology loader module that receives a partial topology from another module associated with the media engine. The topology loader implements logic operations that convert a partial topology into a full topology, which may be returned to the media engine for presentation of the media stream(s) to a user.

摘要： The present invention provides a method for matching the rate of presentation of digital video data at a receiver/client with the rate the server is serving the data without the need of a voltage control oscillator or other hardware. An embodiment of the invention compares the presentation time at the receiver with the server elapsed time estimated from timestamp values on the served data. When the presentation time and the server elapsed time differ by an unacceptably large amount, an adjustment is made to the audio data stream to re-synchronize the presentation time with the elapsed time, which effectively also synchronizes the overall presentation rate with the overall server rate. The video data stream is then synchronized to the adjusted audio stream. The video data stream and audio data stream are converted to analog signals for presentation.

摘要： A system processes an audio signal and a video signal by using different devices, thereby preventing a so-called lip sync error. The processing time (represented by processing-time information) from the start of reception of a supplied video signal in a video processor apparatus to the start of displaying a video corresponding to the video signal on a display screen of a display device is acquired in an amplifier device from the video processor apparatus through a control signal line. In accordance with the acquired processing time, a delay processor delays processing of an audio signal supplied from the delay processor.

摘要： A video signal and an audio signal are transmitted from a source device (400) to a sink device (410) in conformity with respective predetermined interfaces through respective transmission channels. The respective interfaces include bidirectional interface such as an HDMI and an IEEE1394. A controller (420) acquires delay information (TLv) representing the total delay time of the devices connected to the transmission channels conforming to the bidirectional interface and corrects the difference in reproduction time between the video and audio signals by using the acquired delay information (TLv).

摘要： A method by which a DTV receiver that receives a terrestrial broadcast DTV signal may automatically determine the local time for the local terrestrial broadcast region, as well as DTV receivers that implements such a method, is described. The method includes obtaining a unique identifier of a terrestrial broadcast signal, wherein the unique identifier is transmitted as part of the terrestrial broadcast signal, accessing a memory to obtain a local time offset and a Daylight Savings Time (DST) observance indicator associated with the unique identifier, and calculating the local time based on the local time offset and the DST observance indicator. Additional methods for providing channel availability information to a user based on the unique identifier are described.

摘要： In a signal transmitter and a signal receiver, a multiplexing part multiplexes a video signal and a time-base-compressed audio signal on the basis of a multiplexing control signal to transmit the multiplexed signal through a data line in the signal transmitter, and a demultiplexing part demultiplexes a video/audio multiplexed signal received through the data line into the original video signal and audio signal by a demultiplexing control signal in the signal receiver. According to the so-configured signal transmitter and signal receiver, it is possible to realize a signal transmission system compliant with the DVI standard, in which the audio signal as well as the video signal can be transmitted.

摘要： A video apparatus for processing an input video signal in synchronization with an external reference signal is provided. The video apparatus includes a phase compensation FIFO memory and a measuring device. The phase compensation FIFO memory is configured such that the input video signal is written in synchronization with a clock demodulated from the input video signal and the video signal is read in synchronization with an internal reference clock of the apparatus generated from the external reference signal. The measuring device is configured to measure an amount of jitter/wander of the input video signal based on a calculation of a difference between data volume of the video signal obtained in the FIFO memory and a predetermined reference volume.
