Definitions
- Sung has means for breaking up a compound AV stream and then applying an appropriate temporal offset to each stream to achieve synchronisation of the outputs during playback.
- the differential buffering by FIFO units follows the system decoder but precedes the decoding of the audio or of the video.
- handling the component delays with the components still encoded generally involves less processing, handling of synchronisation (particularly if done at source) can create its own problems when it comes to determining just how much delay is to be applied to each component stream.
- Figure 1 represents an arrangement of three interconnected devices forming an audio/video cluster
- a first arrangement of interconnected devices is shown in Figure 1 , with three devices 10, 12, 14 forming a cluster 16 based around a respective bus 18 supporting communication in accordance with IEEE Standard 1394 connect and communications protocols.
- IEEE 1394 IEEE 1394
- the devices in the cluster 16 comprise a source device 10 coupled via bus 18 to a pair of presentation devices, in this example a television 12 for showing the image component of a combined AV stream from the source, and an audio processor and playback system 14 for reproducing the audio component of the AV stream.
- one possible configuration for the source device 10 comprises an audio stream buffer 20 and a video stream buffer 22 for receiving separate input components from a remote signal source 24.
- a controlling processor 30 which reads the processing latencies from the tables (not shown) for destination devices 12, 14, the buffers are used to apply a respective delay to at least one of the two data streams to combat the differing processing latencies in the video 12 and audio 14 destination devices.
- a multiplexer stage 32 combines the temporally offset audio and video from the respective buffers into a single data stream for transmission via the 1394 bus 18.
- the source device optionally further comprises data processing means interposed in the signal path between the buffers 20, 22 and the multiplexer 32.
- this further data processing means may take the form of an audio signal processor ASP 34 on the output to the audio signal buffer and a video signal processor VSP 36 on the output to the video signal buffer.
- the source 58 may comprise an optical or magnetic disk reader and, instead of a digital data bus, the data channel from source 60 to destination devices 62, 64, 66 may be a wireless communications link 68 for which each of the destination devices is provided with at least a receiver and the source device is provided with at least a transmitter.
- a data processing system that comprises a cluster of devices interconnected for the communication of data in streams, particularly digital audio and/or video data.
- One of the devices is a source device for at least two data streams to be sent to one or more other devices as destination devices of the cluster.
- some or all of the devices carry respective tables identifying, for that device, an identifier for each type of data stream that the device can process together with the processing delay for that stream.
- the or each such table is accessible via the cluster connection to whichever of the devices, at source, destination or in between for the signal, is handling application of the necessary offsets.
