Introduction

Z Series

A wireless Transmitter HDMI comes with the separate tuner/media unit, which sends digital wireless audio and video to the Display Unit. The TV itself has no ports, and instead connects wirelessly to a separate box that handles all wired connections. The flagship VIERA plasma in 2009 is the Z1 series, with a revolutionary one inch thin panel design and Wireless HD connectivity. to deliver the ultimate sleek, uncluttered HDTV viewing experience. VIERA CAST web menu with the new streaming HD movie rental capability via Amazon Video-onDemand. The Neo PDP design of the VIERA Z1 produces a brighter picture, deeper blacks, improved native contrast ratio (40,000:1) and Full-Time 1080 TV lines of motion resolution. 1080p resolution, a THX Certified Display; an Infinite Black panel; 600Hz Sub-field Drive; and VIERA Link, and VIERA Image Viewer for playing back digital still images and AVCHD videos recorded on SD Memory Cards.

Wireless HD technology can transmit full HD video signals, and audio and control signals wirelessly. This wireless transmission system was developed by Panasonic in collaboration with SiBEAM Inc. It can transmit uncompressed 1080p full HD content wirelessly with no deterioration in quality by using 60GHz millimeter wave radio. The picture on the screen goes undisturbed even when people interrupt the wireless communication path, and overcomes the highly directional nature of millimeter wave radio. This is achieved by incorporating beam steering technology.

Slide #8

Tuner Box

The TV itself has no ports, it connects wirelessly to a separate box that handles all wired connections.

FRONT

The front side of the box has a plastic panel, under which are its ports. The front side has an SD card slot, HDMI port, S-Video port, composite cable ports, and a PC input.

REAR

The back of the box has many ports. From left to right, you'll find two component cable input ports, a composite input port, three A-V HDMI inputs, an HDMI output, a digital audio output, a RS232C port, VIERA Cast LAN input, and an antenna cable in port.

Slide #9

(RF) Radio Frequency Remote Control

The signals that propagate all around the room can be used to operate equipment without having to worry about the direction that the remote control is pointed. This allows easy operation of a Tuner that is placed inside an AV rack.

The TV comes with a RF Remote Control.

The Tuner Box has RF Remote Control receivers. (The Box does not have an IR Receiver).

The Display unit does not have RF receiver but it has an IR Remote Control receiver.

An IR Remote control can also be used but it has to be pointed towards the TV

This remote control uses 2.4GHz frequency. Please do not place this control near any other device which may receive interference from the frequency.

Slide #10

Connection

This Unit is designed to be connected wirelessly with the Tuner Box, but it can also be connected to the Tuner Box via the HDMI cable.

Slide #12

Wired Connection

The Display Unit can be connected directly to the Tuner Box using HDMI cable

If the TV is not operating because the Wireless Unit is defective, connect the Display Unit to the Tuner Box directly using the HDMI cable. The TV can be operated while the Wireless unit is been replaced.

Slide #13

Display Unit Only (Tuner Box Disconnected)

When the Display Unit is connected only to the WiHD Receiver, the power can be turned ON and Off only with the IR remote control when it’s pointed at the Display Unit.

“No signal from tuner unit. Please check the connection between tuner unit and monitor” is

displayed 20 seconds after the power button is pressed. There’s no OSD shown when any of the R/C buttons or the VOL+, VOL-, CH+, or CH- buttons on the

TV are pressed. OSD (Service Mode Menu) can be obtained when the IR remote control, combined with the VOL-

button on the TV is used to enter the Display Unit Service Mode.

Digital Signal Processing (Tuner Box)

Circuit Explanation

The main function of the A board is to select and process one of the incoming video signals. Video inputs 1 and 2, Component Video Inputs 1 and 2, PC input, and the composite video output of the tuner are all connected to IC3001 for selection. The video output signal of the switch can be in any of the three formats: Video, Y/C, or Y, Pb, Pr. The selected output enters IC4510 (HDMI I/F Receiver/ Sound Processor). A comb filter inside IC4510 converts the composite video signal of the main picture to Y and C (luminance and chrominance) signals. S-Video, which is already Y/C separated, simply passes through the comb filter.

At the completion of this process, the format of the composite or S-Video signal is now the same as a digital 480i component signal. If the incoming video is in the 480p, 720P, or 1080i format, the Y, Pb, and Pr signals undergo A/D (analog to digital) conversion only. The 10 bit YUV data is provided to a video switch inside IC4510.

The HDMI signal from the HDMI ports is connected to IC4510 for selection. The HDMI receiver section of IC4510 converts the incoming HDMI signals to a YUV video signal. The 36 bit RGB digital video signal is provided to the PEAKS AVC IC, IC5100.

Digital television reception of the tuner is output in the form of an IF (Intermediate Frequency) signal. The transport stream from the tuner enters the VSB I/F (Interface) section of IC8001 where the video signal is extracted and converted to YUV data. The JPEG data of the SD card enters the JPEG I/F section of IC8001 for conversion into YUV data. The PCI bus I/F signal is also connected to IC8001 for processing.

The selected picture data is then converted to LVDS signal and is then outputted to IC5100 (Global Core 6). OSD from IC8001 is mixed with the video signal inside IC5100. The LVDS output from IC 5100 is provided to the DH board (HDMI Out). Here the audio signal from IC4510 is introduced to the LVDS transmitter circuit. TMDS Data Clock, DDC IIC, and HDMI CEC from the LVDS transmitter circuit are provided to the Display unit through the HDMI cable.
