The picture panasonic TV of 432 lines letterbox is taken from the [katheto] of low passage infiltration of initial 576 lines, and additional the [ypsiperato] infiltration is transmitted in the [ypometaforea] 4.43MHz at duration the 144 black lines, that allows in the PAL+ of receptor in order to [anadimioyrgisei] a the 16/9 picture of high resolution. So that it is taken the biggest breadth of area for brightness (5 MHZ) and in order to decreases diagonal-colour and diagonal-brightness, the phase of [ypometaforeas] two [sympeplegmenon] lines of successive sectors is reversed. This process, known as “colorplus,” Panasonic TV allows (with the help of memory of frames in the receptor) her cancellation diagonal-brightness near adding the high part of spectrum of two successive frames, and his reduction diagonal-colour with their abstraction. A compensation of locomotion is required in order to it avoids the hand made objects that are imported with the process colorplus in the fast moved objects panasonic TV, which, that are added the need for a memory of frames, contribute in the relatively high cost of running PAL+ of receptors. The PAL+ system leads to a subjective quality equivalent with d2-MAC in receptor 16:9 to the good reception terms (high proportion of signals/noise). So that is informed the receptor for the form of program that is radio Panasonic TV transmission (4: 3 or 16:9), making signal pieces (WSS: the wide screen that makes signal) and the additional information (healthy way, etc.) they are added in first half line 23 (fig 1.8), which allows in the receptor in order to it adapts his form of demonstration panasonic TV. Signal WSS can also be used from usual PAL 16/9 receptors in order to it simply modifies the [katheto] breadth according to form, which is reported sometimes as “PAL+ of poor person. ” After this import (potentially no too much big), now effort are described as much as possible more simply the beginnings that have allowed in the establishment of new digital television models and the services . The programmable micro CONTROLLER panasonic tv of the keyboard i8042 is a mediator between the keyboard, to which it is attached by the interface, which is described above, and who master processor, to which it is attached by the parallel interface. The micro CONTROLLER accomplishes continuously signals internal microprogram monitoring of the keyboard and instructions of the master processors. This microprogram (keyboard expensive desk BIOS) becomes in the controller' stored; s internal covered ROM; it is not outside accessible, and the control desks can a sentence property device be held. Because the controller' S-enterprise-logic, it reacted to the processor' Software-introduced; S-instructions and the interface' s signals relatively slowly: the period of reply is measured in the 10 microseconds. Additionally as a check of the keyboard, the software-controlled and read lines of the controller' s-external ports are used, in order to produce the control signals of the gate A20 and the hardware resetting signals; they are also used to read the signals from the Motherboardkonfigurationsüberbrückern to. Additionally to the keyboard interface that supports control desk i8242 similar interface for another device: the mouse PS/2. after initialization (the hardware reset), takes the tester either the PS/2 or at the mode, dependent on the condition of the microchip' on; S-Besonderestift. In at the mode, that supports control desk mouse functions and does not ignore all mouse instructions. The mode is preselected by the suitable attitude in the BIOS attitude. The tester informs itself with the master processors over the parallel 8-bit communication line. That control desk is preselected, released by the CS# signal of the address coding by addresses 0060h and 0064h. The controller' to sinter registers become by the system address bus' preselected; Line SA2. Measured value and - the IORD# and IOWR# signals tax write; they are produced, if the master processor accomplishes instructions INSIDE and OUT, and/or. Afterwards the control desks occupies addresses 60h (data pointer) and 64h (command and status register) in the CCU input/output address area. The functions of the controller' S-registers are registered in table 7.1. The data, which will receive over the interfaces from the keyboard and from the mouse, and data, which that sends to control desk in retort on the instructions, publication to it Panasonic TV, from the data pointer are read. The data pointer is too written, in order to publish the instructions and data, which to the keyboard and the mouse, as well as the data are addressed, which are addressed to the control desk. The instructions, which are addressed to the control desk, are written into the register of instructions. The controller' S-mode of operation (keyboard and mouse close on and interrupt a making possible, Scan Codegetriebe and other parameters), is stopped by the instruction byte, which is sent to the control desk by a special instruction. Before everything is written to the control desk anasonic tv, its usefulness must be determined. Bitten 1 of the status register (port 064h) shows controller' on; s, which is more ready/busy condition.
