Abstract: A “call relative counted” script instruction is interpreted by a script interpreter of an eight-bit, register-based, virtual machine. In one embodiment, the script instruction has a first argument field and a second argument field. Interpreting the script instruction causes a jump to a location identified by a label in the first argument field. After a number of script instructions identified by the second argument have been interpreted, the interpreting of script instructions automatically returns to the next script instruction after the call relative counted script instruction. In one example, the first argument is a label, the label in turn identifying the location to jump to. In another example, the first argument directly indicates the location to jump to. The instruction is useful in allowing multiple higher-level scripts to reuse different parts of a common lower-level block of script. The common block performs a common function required by the higher-level scripts.

Abstract: The present disclosure relates to simplified monitoring and transmission of a binary switch position by means of coded switching, in which corrections caused by different pulse edge delays are eliminated. According to the disclosure, an auxiliary voltage which is to be transmitted when the switch position is closed is coded using two identical pulse edges of two different pulses, that is to say using either the two connection edges or the two disconnection edges of the two pulses. As a result, the previously known pulse duration modulation is replaced with modulation of the delay time between the two pulses. The two pulses mentioned can be repeatedly generated inside a basic period, which is independent of the auxiliary voltage, and have, for distinguishing purposes, a connection duration or pulse length which is different but is independent of the auxiliary voltage.

The system is easy to learn and the keypads may be used on portable devices such as PDA, hand-held computers, hand-held text-messaging devices and telephones.

The controller may receive updates to its data store from a server through a network connection.

Abstract: It is intended to remove a risk of illegal high quality restoration while enabling trial viewing of contents such as music, to make it possible to reproduce contents with high quality by acquiring a relatively small amount of data, and to make it possible to implement hardware at a lower cost. To generate trial listening data containing dummy data, a pseudo random number R is generated first. A remainder r of R divided by 128 is calculated. The remainder r is coded and incorporated into high sound quality restoration data. A bandwidth limitation region of trial listening data is replaced by dummy data starting from its rth bit. As a result, the head position of the dummy data in the trial listening data varies frame by frame, whereby the safety of the trial listening data can be increased.

Abstract: A machine code API can be loaded onto an eight-bit, register-based virtual machine. A higher level script that is interpreted by a script interpreter of the virtual machine can then use the new functionality provided by the added API. The API may, for example, provide access to hardware of the underlying platform that is otherwise inaccessible to a higher level script. The API loading feature sees use where the virtual machine is remotely deployed in the field but can be communicated with via a bidirectional link. The API is communicated to the virtual machine via the bidirectional link and the API is loaded onto the virtual machine. The API is assigned a reference that a higher level script can use to call the API. Using this feature, various APIs can be loaded and their operations tested. Unwanted machine code APIs can also be erased from the virtual machine.

Abstract: A script is stored on a remote control device. When a key is pressed, an interpreter on the remote control device interprets the script thereby causing codeset information (for example, key codes and protocol information) stored on the remote control device to be used to output a sequence of marks and spaces. Adjacent marks are combined into a larger mark and adjacent spaces are combined into a larger space. From these marks and spaces, a mark/space table and a string of timing information are generated. The mark/space table and the string of timing information are then used to generate an operational signal that is transmitted from the remote control device. In one embodiment, only one mark/space table and one string of timing information is ever present on the remote control device at one time. This reduces memory requirements, thereby reducing manufacturing cost of the remote control device.

Abstract: A multi-level signal uses the third/fourth signal level to signal both a word clock edge and a data word boundary. At the receiver, a level detector detects a transition to or from the third/fourth level as a clock signal transition and the word boundary. The bit clock can be recovered using a conventional clock multiplier. Bi-level signaling is used for data between the word boundaries. Additional signal states are available in the multi-level signal by modulating the pulse width at the third/fourth signal level.

Abstract: A remote control device detects that a command has been chosen. A command may, for example, have been chosen by a user pressing a key on the remote control device. In response, the remote control device generates a mark/space table and a string of timing information. The string of timing information includes entries that refer to mark time values and space time values in the mark/space table. The string of timing information also may contain special control portions (for example, a control portion can indicate that a portion of the string of timing information should be repeated a given number of times). The mark/space table and the string of timing information are then used to generate an operational signal that is transmitted from the remote control device. The mark/space table and string of timing information is a particularly compact way of describing an operational signal for a remote control device.
