i.LINK is a serial digital interface that supports the bidir ectional transmission of audio and video signals, commands, and even component status information. All that is needed to hook up i.LINK components are i.LINK connecting cables. Audio and video components connected within an i.LINK configuration can be used to perform a wide range of operations and data exchanges that is sure to expand as the number and variety of i.LINK components gr ows. Since i.LINK allows data to be transmitted from one component to other components to which it is not directly connected, there is no need to pay attention to connection or der . However , due to differences in characteristics or specifications, operation of or data exchange with certain i.LINK components may not be possible, even when they ar e connected. Branch connections · Any i.LINK component with thr ee or mor e i.LINK connectors can serve as a branch point. · Up to 63 i.LINK components can be connected in a single configuration. However , the maximum number of components that can be daisy-chained in a single route is 17 (i.e., a maximum of 16 i.LINK connecting cables in a row). Each i.LINK cable used in a single route is called a "hop." For example, there ar e 6 hops in the route between A and C in the illustration below , and 3 hops in the route between A and D.

i.LINK is a trademark pr oposed by Sony Corporation and accepted by companies throughout the world as an easy-toremember name for the IEEE 1394 world standard of the Institute of Electrical and Electronics Engineers.
Each route between A and B; A and C; A and D; B and C; B and D; and C and D in the illustration above can have 16 hops (i.e., 17 components). Loop-connection A signal output from one component is transmitted to all other components. A loop connection should thus be avoided to pr event the return of a signal to its source.
Correct Incorrect (looped)
Before an audio signal can be transmitted between i.LINK components, a "LINC" must first be established between the receiving component (of the audio signal) and the sending component. Establishing a "LINC" means establishing a logical path for the transmission of digital audio signals between the two components. Each logical path has an ID number . Since the component that sends an audio signal must output the signal to a path, and the component that r eceives the signal must input it from the same path, the path must be mutually known by both components. During the establishment of a LINC, the following communication occurs between the two i.LINK components. Example A component establishing a LINC with a CD player in order to receive an audio signal from the CD player 1 The component that will receive an audio signal from the CD player sends a request and path information to the CD player to establish a transmission path for the audio signal. 1

Invalid format
When an empty packet has been received after establishing a link. (This problem occurs when the opposing playing is not in operation, when an MD is used to select input for a CD which is not being replayed, and when a CD is not being replayed when recording from a CD to an MD.) This problem occurs when a signal in a separate format (i.e., a signal which cannot be replayed) is detected (i.e., when recording to an MD when the channel is being used for DV signals).

· An attempt has been made to transmit a signal over a broadcast channel. Sony DVs are designed to allow the use of 63 channels. MDs also have the same design, and it is impossible to use the same channel after it has already been used (i.e., the same channel cannot be used again without the ability to obtain channel authorization). · Unable to perform clock synchronization The remote device has been poorly designed and communications have reached the limit of stable PLL (where the PLL is a chip used to stabilize the clock). Home device okay; fault lies with remote device. · No input signal (Used for units able to perform i.LINK switching without linking.) ·No input signal because remote device not powered on (Used for units requiring linking for i.LINK input switching.) · Bus full Number of signals being transmitted over the bus exceeds the maximum amount of signals which may be transmitted. · i.LINK failure Displayed on all units connected. · Bus reset Not displayed in C code because too complicated. · Bus reset Displayed only for recording unit. (C code displayed only on MD when recording from a CD to an MD.)

NO SIGNAL No input signals detected in i.LINK mode. (This problem occurs when the power of the opposing unit is turned off after linking.) Unable to interrupt output because bus is being used to ca- BUS FULL pacity. (This error occurs when multiple DV signals are being output and the bus is too busy to generate an interrupt.)

Note 1 : i.LINK messages displayed only in upper-case characters. Note 2 : Distinctions between "No signal" and "Cannot link" messages made by C code. Note 3 : Note that No. 9 may not always be properly detected. Comment 1 : As before, a "Can't copy" message is displayed when it is impossible to record because of SCMS restrictions. Comment 2 : C code C78 represents an improper connection (i.LINK connection).
