    摘要: A method of managing a sound source in a digital AV device and an apparatus thereof are provided. The method of managing a sound source in a digital AV device includes: extracting at least one sound source from sound being reproduced through the digital AV device; mapping an image to the extracted sound source; and managing the sound sources by using the mapped image. In addition, preferably, the extracted sound source is registered, changed, deleted, selectively reproduced, or selectively deleted by using the image. Accordingly, sound being output can be visually managed by handling the sound sources separately, a desired sound source can be selectively reproduced or removed such that utilization of the digital AV device can be enhanced.

    摘要: The disclosed embodiments relate to a system and method for maintaining synchronization between a video signal and an audio signal that are processed using clocks that are locked. The system may comprise a component that determines at least one initial level of a buffer, a component that determines at least one current level of the buffer, and a component that determines an amount of drift by comparing the at least one initial level of the buffer to the at least one current level of the buffer and adjusts the clocks to maintain the initial midpoint level of the buffer if the amount of drift reaches a threshold level.

    摘要: In an audio signal delay apparatus and methods, an audio signal modulated by biphase mark modulation is received and a header part of the audio signal is identified. Thereafter, a data part of the audio signal is demodulated to store the identification data and the demodulated data part in a memory, the identification data from the memory is read out to reconstruct the header part after a specified time. Subsequently, the data part is read out from the memory to modulate the data part by the biphase mark modulation and the reconstructed header part is combined with the modulated data part to output the combined data. Preferably, the identification data is represented by two bits.

    摘要: A system and methods are provided for presenting processed audio data and processed video data to corresponding outputs in a synchronized manner. Video and audio data from a multimedia stream are received by a processing system. The video data is processed through a video processor. The audio data is processed through an audio processor. Processed audio data is stored in memory through a VIP data port. A bus-master engine is used to delay a transfer of the audio data from memory to an output port. The delay is determined so as to allow video data enough time to be processed and output in synchronous with the audio data transferred from memory. Once the delay has been overcome, the bus-master asserts a trigger in the data bus to initiate the transfer from memory to the output port.

    摘要: Video picture signals are received via at least three channels. At least three control instructing operators are provided in correspondence with the channels. Each control instructing operator is operable to give a signal control instruction for the corresponding channel in accordance with an operated amount of the operator. Controller performs signal control on the video picture signals of the channels on the basis of the respective signal control instructions given via the control instructing operators. Synthesizer synthesizes the video picture signals of the channels having been subjected to the signal control by the controller. Video picture signals of two desired channels are designated, and a contact-type operator gives signal control instructions, corresponding to a predetermined position of the operator contacted by a human operator, with respect to the video picture signals of the designated two channels. By the signal control instructions, signal control is performed on the video picture signals of the designated two channels to thereby synthesize the video picture signals.
