    摘要： A number of domestic audio/video apparatuses (10,12,14) are interconnected by a Domestic Digital Bus (16) for the exchange of control information. A User I/O subdevice (41) in one apparatus is addressable by a control subdevice (22) of another apparatus to allow the display of menu items defined by the control subdevice. The User I/O subdevice returns user control signals by reference to the defined menu items. The right of menu control can be transferred via the User I/O subdevice to and from other control subdevices (20 etc.) to allow integration of the menu control functions of the different apparatuses.

    摘要： A system of domestic video apparatuses (10,12,14 etc.) are interconnected by video cables (64,66,68) and also by a serial data bus (D2B,16) having distributed control intelligence (20,22). Within each apparatus, signal generator and/or detector functions are defined, which can be activated and controlled via the bus (16). The video cable connections (64,66,68) between various plugs (26-1,2,3, 52-1,2,3, etc.) of the apparatuses (10,12,14) are identified automatically by interrupting signal transmission from all apparatuses involved then allowing a single transmission from an input to the connections and detecting the where the signal is output. By repeating the process with other all connections may be traced. The automatic identification of cable connections occurs without requiring additional conductors for cable detection signals.

    摘要： A domestic video system includes a number of interconnected video apparatuses (10,12,14), at least one of the apparatuses including a facility for conversion of the aspect ratio of video signals. The system further includes control signalling (20) operating via a standard serial bus (16) for systematically interrogating each apparatus in a signal path to determine whether aspect ratio conversion is necessary in the signal path and for selectively enabling or disabling any conversion facility in the signal path to effect such necessary conversion. The control means implements a strategy for eliminating unnecessary conversion of aspect ratio in the signal path, and also chooses to effect conversion as late as possible in the signal path when faced with more than one available conversion facility.

    摘要： Apparatuses (1,2,3) of an audio/video system convey user commands to one another via a serial control bus (4). The user commands convey key activations on a remote handset (18a), whose keys include both "normal" keys such as "mute/unmute", and "repeat" keys such as "volume up" and "volume down". To convey a repeat key activation, a first control means (12) within one apparatus addresses a key activation message to a second control means (32) within another apparatus. The second control means (32) synthesises locally a repetitive series of user commands, until a key release message is received. The need for repetitive user command messages to be sent via the control bus is thereby eliminated, and the frequency of repetition can be defined locally to give consistent response to user commands. The second control means (32) can also implement a de-bouncing function, disregarding duplicate user command messages sent by a third apparatus (2) which also responds to the handset (18a).

    摘要： A local communication system has a number of stations connected for the communication of messages by one or more data channels. One of the stations comprises a display device operable to display messages sent by other stations in one or more of a plurality of fields. Each message to be displayed is given a display lifetime (80-84), which is determined by a mode value (74-78) set by the originating subdevice or commonly assigned by the display device. The display determines whether there are sufficient display fields available (68) to display a received message and handles the timing (88) and subsequent removal from display (90) of a message on expiry of its display lifetime, independently of the originating station.

    摘要： The test apparatus (PC,KB,DIS,PR,IF) communicates via a standard serial bus (12) with a device under test (DUT) to verify conformity with a standard application protocol defining the format, meaning and applicability of messages passed via the bus (12). The apparatus generates a test sequence of commands and requests and analyses the replies of the DUT for conformity. The test sequence and the analysis are adapted automatically in response to previous replies of the device, to provide a thorough but efficient test of the device and any subdevices identified within it. Where the standard application protocol defines extended autonomous cooperation between devices, the test apparatus emulates one or more further devices to be controlled and interrogated by the device under test.

    摘要： The system comprises a number of stations interconnected for the communication of control messages which are multiplexed with digital audio signals. The control channel is divided into eight parallel channels, and each station is allocated one channel to transmit on, while it receives from other stations on the other seven channels. Messages on each channel are segmented into finite message units. When a longer message is to be transmitted, the receiving station implement a locking mechanism such that message units will not be accepted on other channels until all message units of the message have been received. To allow the number of stations to exceed the number of data channels, some of the stations are designated "slave only", and share a single channel for the transmission of control messages. To avoid conflicts, these stations are permitted to transmit only in response to request messages from a station having its own exclusive transmit channel.

    摘要： In a single channel communication bus system, e.g. D.sub.2 B, sometimes two devices of the same type must be initialized at the same time. These devices start out with the same address installed by the manufacturer. The installed address includes follower bits which can be changed to account for the presence of other devices. During initialization, all devices are set to a dummy address and the installed address is stored. Each station then looks for devices having its own installed address. If, after 3 tries, none is found then the stored address is used. If other devices having the installed address are found, the follower bits can be changed. The station iterates until all possible follower bits are exhausted. In this way the stations of the same type have an improved likelihood of being initialized with distinct addresses.
