  1. 1. PML Portable Multimedia Link Preliminary Design Review Class: System Design 1 Instructor: Dr. Ports Date submitted: 10/27/03
  2. 2. Product Technical Description The Portable Multimedia Link (PML) unit is a small and powerful computer that can reside in the owner's vehicle. It consists of three main components - the PML unit itself, a VGA LCD display, and a power supply. At the heart of the PML is a mini-ITX mainboard running a 1 GHz CPU. The user interfaces with the unit through means of a touchscreen on the LCD display. The PML is capable of handling several multimedia applications: - Plays CDs, DVDs, MP3s, and VCDs (including CD-Rs and CD-RWs) - Plays Divx, Mpeg, Avi and Windows Media files - Can run almost any desktop application The audio from the PML will be played through the owner's vehicle speakers. The unit will either connect to the existing car stereo (by means of an RCA-out or FM modulator), or be hard-wired to the vehicle's speaker system. The VGA LCD will be mounted in the dash of the owner’s vehicle. This provides easy access to the screen, uses less space, and prevents glare. The PML will tap into the vehicle's battery for power, and might have a rechargeable battery for backup purposes. The final unit might incorporate a remote power/reset switch so that the user can turn the PML on or off without having to get in the vehicle. The unit will be running Windows XP as the default operating system. Therefore, it supports just about any Windows program. Support for different media types will be accomplished with several player programs and codecs for both audio and video. The PML will also be connected wirelessly to the owner's home PC by means of two 2.4 GHz wireless USB network adapters. This adds to convenience since each adapter can be plugged into either computer’s USB port without having to install an internal network card. The adapters will have a peer-to-peer connection that will allow the user to download media files from the home PC into the PML unit at a very fast rate. The files will then be available for viewing and/or listening in the vehicle. 2
  3. 3. Detailed Product Specification The hard disk we are going to incorporate into our system is a Diamond Max plus 9 60GB Maxtor. This hard disk is equipped with fluid dynamic bearing motors. This helps to minimize the noise of the drive, which is especially important in the personal video recorder applications. This fast performer at 7200 RPM and fast Ultra ATA 133 interface is the most reliable and robust single-head/single platter hard drive on the market. This capacity of storage is being used to allow the user to adequately store data files downloaded from the main system (home PC). (See Table 2.1) The 7” in-dash retractable VGA-LCD touch screen consist of 2 video inputs (2× RCA) and a VGA input (1x 15 pin D-SUB) with on screen control. The screen consists of a High Resolution Display up to 1600 x 1200 and has auto display adjusting with supported resolution of 640 x 480 ~ 1600 x 1200. This retractable VGA-LCD display is being used instead of a TFT-LCD because of its high resolution for an easy to read interface, clear video playback, easy access for the user to select a task for the system and its easy access location (stereo slot). (See Table 2.2) The Via EPIA M10000 motherboard is the world's smallest x86 mainboard platform, and is fully compatible with Microsoft® (Microsoft Windows XP is the likely operating system of choice) and Linux Operating Systems. This board has an integrated AGP-graphics adapter with MPEG2- decoder-chip that enables proper DVD-Playback.. The AGP-graphics-adapter uses between 8 and 64 MB of the main-memory as graphic memory and this is good enough for our system. The board comes with one VGA-Output and one TV-Out(S-Video) which is compatible with not only the 7” in- dash VGA-LCD but other monitors and televisions as well. The Floppy-connector will be connected to the hard disk and the Toshiba slim line DVD ROM. The LAN-Interface on the EPIA M10000 is a RJ-45 (10/100 Mbit). This however will not be used as we are going to use a USB wireless adapter. As for sound, the board’s sound card has 1x Line In, 1x Microphone, 1x Line Out and 1x digital (coaxial). The VIA C3 1000 MHz processor has a fan and is already mounted hard on the board and therefore not changeable. The 40-mm-fan makes noises at about 38.9 dBA, however, this is likely to be dampened by the Sorbothane. The S/PDIF-Output can be switched into Cinch-TV-Output-mode. The third and fourth USB-ports, both FireWire-ports, and the second serial port are available only with an optional adapter-cable. (See Table 2.3) The VIA C3 processor is the first x86 processor on the market with embedded security features that enhance the protection of sensitive corporate and personal data. The processor is based on an advanced new CoolStream™ architecture that delivers all the necessary performance for running even the most demanding digital media applications while maintaining ultra low levels of power consumption and effective heat dissipation - making it the ideal solution for powering a new wave of innovation in secure, quiet running, small form factor PCs and digital entertainment devices. This is a positive aspect in our design because of the present risks involved with a fast processor and data transfer from one PC to another. Such risks include overheating and viruses that are allow others to access PCs via a network respectively. Based on an advanced new CoolStream™ architecture, the VIA C3 processor is available at speeds starting at 1GHz and is packed with new digital media performance features, including support for four new pipeline stages, SSE multimedia instructions, StepAhead™ Advanced Branch Prediction, efficiency- enhanced 64KB Full-Speed Exclusive L2 cache with 16-way associativity, and a full-speed FPU. This processor speed allows for the fast access to the on board communication of components and 3
  4. 4. software. When coupled with the VIA Apollo CLE266 chipset, the new VIA C3 delivers exceptional performance for all the most critical productivity, Internet, and digital media applications, including multimedia slideshows, web browsing, digital video, and MP3 and DVD playback which links directly to our product description of playing multimedia. With a typical maximum design power of just over 10 watts at 1GHz, the new generation VIA C3 runs extremely cool and delivers very low levels of energy consumption. This not only makes it the ideal solution for powering a wide variety of low profile, small form factor PCs, but also enables very low noise system design implementations. The explosive growth of PC networking and the Internet has significantly increased the demand for effective computer and network security solutions that enhance the protection of sensitive personal and corporate data. To address this need, the new generation VIA C3 is the first native x86 processor in the world to integrate a high performance, hardware-based Random Number Generator. The Padlock Data Encryption Engine not only helps ensure greater confidentiality, integrity, and authenticity of electronic data stored in your computer or transmitted over a network or the Internet, but also enables a host of powerful new security applications, including heavy-duty data encryption and safer online transactions. The Toshiba SD-C2302 6× IDE slimline DVD-ROM drive delivers 6X performance to mobile road warriors. With data transfer rates up to 8,112KB/sec for DVD media, and 3,600KB/sec for CD media, the drive provides outstanding multimedia performance for the mobile market. Random access times of 130ms for DVD and 95ms for CD-ROM also contribute to the drives’ superior capabilities. This drive is also compatible with the VIA EPIA motherboard and also fits the front panel specification which keeps with the design of a relatively small system. (See Table 2.4) The memory chip that we are going to use is a low profile Kingston 266MHz DDR PC2100. The low profile feature goes well with our design as we are aiming for a compact system. It has 184- pin DIMMs and is designed for desktop computers. The 184-pin DIMM provides a 64-bit data path, so they are installed singly in 64-bit systems. To use DDR memory, the system’s motherboard must have 184-pin DIMM slots and a DDR-enabled chipset. A DDR SDRAM DIMM will not fit into a standard SDRAM DIMM socket. Lastly it has an error checking feature with SDRAM Timings: CL=2.5. (See Table 2.5) We are going to use an 11Mbps wireless, plug-and-play USB adapter. Gig Fast’s versatile USB Adapter can connect to any access point or router that runs on the IEEE802.11b wireless standard and has an operating distance of up to 300ft. outdoors and 100ft. indoors. With up to 128-bit WEP for security, the WF741-UIC ensures secure data transmission without sacrificing performance. This adapter is also compatible with most operating systems (98SE, ME, 2000, XP) which is a plus as we are not restricted to using a particular operating system with the Via EPIA M10000 motherboard. (See Table 2.6) Sorbothane is a proprietary, visco-elastic polymer. Visco-elastic means that a material exhibits properties of both liquids (viscous solutions) and solids (elastic materials). Sorbothane combines shock absorption, vibration isolation and vibration damping characteristics. In addition, Sorbothane is a very effective acoustic absorber and damper. While many materials exhibit one of these characteristics, Sorbothane combines all of them in a stable material with a long fatigue life. • Sorbothane has a low creep rate compared to other polymers (rubber, neoprene, silicone, etc.) 4
  5. 5. • Sorbothane has a superior damping coefficient, over a very wide temperature range, compared to any other polymer. • Sorbothane eliminates the need for metal springs to return the system to its equilibrium position after absorbing a shock. Analysis of Design Options Design Approach 1 - Pocket PC design PDA w/ wireless kit and compact flash PIC PML UNIT Power Supply Kit Hard drive and dampening system Custom Software This design was the initial design. The main goal of the design is to create a network between a house PC and the system in the car which would store the data on a hard drive. The user could then access the files and use a media player to play them. The pocket PC of choice is the HP ipaq because of its expandable specifications. It includes a fast 2.4 GHz, 11Mbps LAN card and 128MB of flash. The flash on the pocket PC is to be used as a buffer and would act as an anti- skip feature. The transferred media will be stored on a removable 40GB shock resistant hard- drive. Since a hard drive is not shock resistant a mechanical dampening system has to be built.

PDA/Pocket PC 1 $500 PIC 1 $80 256MB RAM 1 $50 40GB Hard drive 1 $40 Mechanical Dampening System 1 $40 Pros • The pocket PC can be dismounted and used as a regular pocket pc • Expandable storage • Compact design, not so obvious in the car Cons • The pocket PC is very expensive. • The dampening system might not be effective enough to reduce skipping of the hard disk • Many OOB criteria • Software development too complex Design Approach 2 - Tablet PC design 6
  7. 7. Touch screen LCD (mounted on top or on dashboard) Mechanical dampening system PML UNIT Mini ITX Motherboard w/ components Power Supply Kit Wireless LAN kit The second design is basically a small tablet PC directed for multimedia use in the car. The 5 inch touch screen LCD will either be mounted to a swivel on top of the case or mounted on the front console (dashboard). If mounted to the front console the system would be designed such that the user could detach it from the console and clip it to the top of the case. This will make the system completely portable. The custom case will house the motherboard and its components as well as the dampening system and the hard disk. As for the power supply kit, it will consist of a dc converter and a rechargeable 12V battery. As with the previous design approach a 802.11b 2.4GHz, 11Mbs wireless card will be used to link the home PC to the system in the car.

  9. 9. • This design eliminates the construction of a mechanical dampening system. • By replacing it with the shock absorbing material we can reduce build time and save space. • A bigger display increases visibility and makes it easier to use as an interface. Cons • Sorbothane might be more expensive than mechanical dampening system. • A 7 inch LCD is too bulky for an internal retractable design • TFT LCD does not have a high enough resolution Design Approach 4 – External retractable touch screen LCD External retractable touch screen LCD Shock absorbing material PML UNIT Motherboard w/ components Power Supply Kit Wireless LAN kit This design uses a 7” external retractable touch screen LCD that is mounted in the vehicle’s front console. All other features are the same as in design approach 3.

  10. 10. Custom Chassis 1 $30 Dampening Material 3 $50 Pros • Easier access to the screen • Improves commercial appeal • Overall powerful system • Expandable system Cons • LCD more expensive • Not one complete unit Design Selection and Rationale The selected design option was based upon several factors: 1. Cost and Cost Effectiveness 2. Dampening Efficiency 3. Portability and Convenience 4. Compatibility 5. Commercial Appeal In cost consideration, a hard drive was found to be much less for much more memory indicating an increase in cost effectiveness. The average cost of a 1 Gigabyte (GB) compact flash memory was $250 while a 60GB hard drive was found for $60. This is 1/5 of the price of the flash memory and 60 times more, there would however have to be a compensation made in the inclusion of a SRS (Shock Resist System) to prevent hard drive skipping. There were two options to be considered, those being a dampening system and a shock absorbing material. The dampening system had an estimated cost of $40 while the shock absorbing material was sold at $16 for a 12” X 12” X 1/8” sheet. Taking the higher cost of the dampening system plus the cost of the hard drive, the total cost is still a little over a third of the price of the 1 GB flash memory. The economic choice was clearly that of the hard drive and SRS. The decision in the choice of the shock absorbing material over the dampening system was ultimately made by its efficiency rather than cost. The dampening system was to be comprised of a bed supported by a carefully constructed network of shock absorbing springs. The system would be a prototype so the specifications of how effective it would be would have to be tested and measured after it is made, then subsequently repaired if demand specifications were not met. This might have resulted in delays and the meeting of the needed shock resist capabilities could never really be ensured. The shock absorbing material, Sorbothane, was a readily available material and had predetermined specifications that were more than adequate for the PML system. When subjected to an impulse of 23 G’s (Gravitational Force), Sorbothane absorbs the force and returns to equilibrium in a time of 10mS. In terms of portability and convenience, a rechargeable battery was integrated into the power supply system. This would allow the PML system to have its own power supply that is charged 10
  11. 11. by the cars battery and then be used in or out of the car. The convenience also includes that the PML will always be on enabling file transmission at any time. When the car is on, power will be directly supplied to the system while charging the battery. While the car is off, the battery will power the system. The initial PML design which attempted to incorporate a PDA as an interface and input device was found to have serious compatibilities issues. Software and hardware would have to be integrated with a number of complex programs and interconnecting devices proving that method to be an extremely inefficient one. In creating the final product, the appearance of the PML was taken into consideration. The size of the unit as well as how it is presented scrutinized for simply the reason of commercial appeal. The State of the Art factor is already high in the system but is pushed even further with the inclusion of a retractable LCD screen. The other options of a mounted screen as well as an attached one were all nice, but the sleek and discrete nature of the retractable touch screen LCD will elevate its commercial value even higher.

This material was used because it is readily available and it is easier to work with in terms of shaping and also because of its high resistance to the environment (rust, heat etc.). The basic components that we found to make up the PML system was a VIA EPIA-ME6000 Motherboard, 40 GB hard drive, USB wireless LAN card, 7” touch LCD screen and a dampening system (Sorbothane material) to reduce the shock of movement and skipping of the hard disk. These components has to be carefully placed into the casing to allow room for air circulation 11
  12. 12. when components are running in the enclosed environment and also to reduce the movement of parts which will cause damage to the system. The system also contains air vents at the rear of the system to allow excess heat to freely vent to and from the system which would allow the system to relatively stay cool when mounted or mobile. The design also allows the prevention of the touch screen from being damaged when not in use and to prevent theft when installed into your car. The system can also be mobile, when we refer it to be mobile we mean that it can readily be connected to any Monitor and we have a readily external power supply jack. The system will also contain easy access buttons to switch the unit on/off. A LED meter on the front of the casing to allow the user to tell the amount of power is left when the unit is running off the battery source. If time and space permits we are also going to try to incorporate a FM/AM tuner to the system design. 2x DDR266 memory-slot LAN Card Parallel Port 2x UltraDMA-133 for drives Motherboard Monitor 1x Floppy- Port connector VIA C3 Processor 12

  18. 18. BUSINESS PLAN Top Level Description Introduction and Description of the Opportunity Entertainment in the car has now become less than luxury but rather a standard addition. The level of technology of how that entertainment is delivered has been increasing rapidly over the last few years. The PAL project last year focused on providing an easier and more efficient way of storing and playing songs. This year’s follow up project, PML, will seek to take it one step further. PML, Portable Multi-media link, will seek to, in addition to playing songs, play movies, but do these in such a manner as to reduce costs, create a friendlier interface, and make an overall improvement on the system. The market on such appliances is not a closed one, but it is still extremely small. PML plans to provide the cheaper and better alternative from the get go making a device that will suit the client perfectly, and with the specific purpose of entertainment, we can create an interface that controls a sophisticated piece of equipment that is easy to use. Product Features In last year’s project, PAL, MP3s were downloaded from the user’s home computer with the use of a wireless network. PML will continue to this but also enable movies to be downloaded and played. Additional memory will also be added by replacing the previously used flash memory with a hard drive. This will include a dampening system for stability. One of the main features that will be added is the use of a touch screen; this will provide the user with ease of navigation through their entertainment experience. Playing quality of the video and audio components will also be improved by adjusting the transmitting devices. With all of this in mind, the biggest selling point that the PML system will have is that, while including all of these luxurious features, it will be extremely easy to use and the price of the system will be kept down to be the same as competitors or even lower. Customer Base Almost every one that owns a car owns a car radio. This product, while not being as simple as the car radio, with the rate of technology and the user friendliness might become, in the not so far future, a competitor. As it is now, every single car owner with a pc could use this device. They 18
  19. 19. are a couple groups of people who would be greatly interested in this type of device and therefore would be the target market. They include technology enthusiasts, movies/music enthusiasts and chauffeur industries, for example limo and taxi services, to provide entertainment for customers as well as people with families, to provide entertainment for the kids. The PML does not even have to be relegated to car use, an alternate power source that can be attached to the system will allow it to be used anywhere on the planet. Preliminary Specifications All the necessary components for the PML system have not yet been determined. However, the overall design and the major components have been selected (see list below). Specifications Hardware Software 7” LCD touch-screen display (VGA) Custom software 2.4 GHz wireless LAN kit (USB) Operating System (Windows or Linux) Shock resistant 60 GB hard-drive VIA mini-ITX Motherboard Drivers, audio/video codecs 256 MB RAM Power Sources (main and battery) Custom casing The PML system will be easy to use. It automatically downloads the media using a fast 2.4 GHz LAN card. This will download the media at approximately 11 Mbps within close range of the home PC. The software that comes with the network card will be preinstalled on the PML system and has to be installed on the home PC by the user. The transferred media will be stored on a 60 GB shock resistant hard-drive to give seemingly endless capacity for music. If we choose to use windows XP as our operating system then windows media player will be used for media playback. This program is very useful as it is able to play WMAs, MP3s and MPGs. The LCD will display the files on the hard-drive and the user will be able to cycle through and choose what to play using the interface. The LCD is located on the top of the PML unit but can be detached and mounted elsewhere. 19
  20. 20. Product Value Proposition The PML system is a versatile device providing the latest technology in entertainment, delivering it in high digital quality. Operation of such a complex device might seem difficult, but with its user friendly interface even a baby could manipulate it. One of the main selling points, however, is that although the “state of the art” factor is high, the price is not. The average car owner will be able to fit this into his or her budget.

The aim/objectives of our project were outlined in the Feasibility Report. The team is focused on and committed to the achievement of this objective. While a tentative completion date of April 2004 has been proposed, we are aiming to have a near complete project by November 2003, so 21
  22. 22. that remaining time can be dedicated to testing and thus fixing any glitches that arise as well as fine-tuning the final product. We have already begun the task of locating and acquiring parts and equipment, and are currently seeking reliable products for the best price to enable use to meet budget requirements. Our team consists of members whose chosen field of study, which are electrical and computer engineering, is directly linked to this project. While the scope of this project is primarily within our fields, we may need to seek assistance from Mechanical Engineering, in the area of designing a dampening system for the hard drive to protect it against bumps while driving. Since this project is of great interest to us, we are very enthusiastic about the design, and thus dedicated to its success. As a result of this, our team members are in regular contact via email, phone and team meetings to discuss ideas, and new developments that could assist or hinder the development of our project. Furthermore, we have the advantage of additional encouragement and support from last years team (PAL-Portable Audio Link).This team produced a similar project, and are willing to assist us in our design and also give us ideas on what direction we should take or avoid in our assembly stages. Drawing on their experience should further assist us in ensuring that our project is completed on schedule and within budget. We also have the added advantage of drawing on the expertise of Dr. Deshmukh and Dr. Grossman, from the ECE department, who are familiar with signals and systems. Two of the nine team members have some experience in coding that is necessary to start creating the software for the system.

Electronics products Risk Analysis Certain risks must be avoided for the project to be completed on time and according to specification. These risks can be divided into four categories: schedule, technical, financial, and marketing. Firstly, in the schedule category, falling behind schedule is a high probability risk. Since none of the members in this group have experience planning a schedule for this type of project, the chances that we will be able to make a schedule and stick to it perfectly are very slim. To avoid this risk we will try to leave buffer zones in our schedule to allow some leeway in how much time we have to complete certain tasks. Another risk in the schedule category is the risk of someone dropping from the team. This would completely disrupt our scheduled plans; however, it is a low 23

In the technical category, the highest risk is not being able to figure out how to complete the final phase of the product: making it work. This is a very high risk because we cannot be sure of the technical difficulties we will have at this stage of the product development. To avoid this risk we will try to have a very well designed product before we actually start building it. A low risk in this category is the risk of it not being possible to create the desired product. This is a low risk because it is highly unlikely that the product we wish to create is not possible to make; however, the risk is still there and we must plan on what to do in case it arises. In the financial category there is only one risk: not having enough money to complete the project. Since the equipment needed for this project might be expensive, this is a high risk. There are a couple ways to avoid this risk. The first way is to design the product to be as low of cost as possible. The second way is to do fund raising and/or find sponsors to fund the project. Lastly, in the marketing category, there are no risks for this project. Since the product we are developing will not be sold on the mass market, there is no possibility for marketing risks. If our product was planned to be sold to the public, a marketing risk would be if another company released a product similar to ours before we have completed our product.
