`
`The Implicit Source Code specifies a distributed system consisting of a plurality of
`devices that are nodes of a network (“devices”). These devices execute a method for
`synchronizing rendering of content provided by a source, where each device maintains
`a rendering time corresponding to the device time when the device renders content.
`
`Implicit source code specifies a distributed system consisting of a plurality of devices.
`These devices include a master rendering device that is set up to render an audio and
`video content stream. This audio and video content stream rendered by the master
`rendering device corresponds to a first content stream.
`
`Implicit source code implements a distributed system consisting of a plurality of
`devices. An architecture of one such distributed system comprising a plurality of
`devices is defined in files videomulti.rule, videoclient.rule,
`ipaqvideo.rule, pcmaudioserver.rule, syncaudio.rule, and
`timesync.rule.1,2 Implicit source code also implements beads or services that run

`on devices that are nodes of a network. Among other services, these beads can
`perform tasks including decoding and encoding content streams, receiving and
`transmitting content streams, synchronizing content streams, and rendering content
`streams.3 Each device is configured using one or more rule files and executes the
`services implemented by the beads specified within the rules file.
`
`Among other devices, the distributed system described in the rules files specifies a
`master rendering device that renders an audio and video content stream.4 This audio
`and video content stream rendered by the master rendering device corresponds to the
`first content stream. Specifically, the master rendering device receives a combined
`audio and video content stream at its local network port 8013 from a content source
`device.5,6 As part of the rendering process, this master rendering device uses the
`avidemux bead to split the combined audio and video content stream into separate
`audio and video streams.7,8 Specifically, functions
`AviDemux_EncodeMessageHandler9 and ChunkProcess10 of bead
`avidemux separate the combined audio and video content stream. Once the audio
`and video streams have been separated, the master rendering device runs the
`bmptorgb bead to decode the received video content stream to generate decoded
