Field testing for parcel collection and delivery operations with the use of a prototype light commercial electric vehicle (EV) built by MMC has begun, according to an announcement by Yamato Transport Co., Ltd. (Yamato Transport) and Mitsubishi Motors Corporation (MMC).

1. BackgroundYamato Transport is working to reduce environmental burden in all areas of its express home delivery operations through a series of initiatives which include: restricting the size of its delivery vehicle fleet; introducing low-emission delivery vehicles; promoting eco-friendly driving habits; reducing driving distances and promoting modal shift*. The Yamato Transport fleet comprises around 45,000 vehicles and the company is intent on contributing to the realization of a low-carbon society through the active introduction of next-generation eco-friendly vehicles. (As at the end of March 2010, the fleet included 11,538 low-emission vehicles, of which 4,659 utilize hybrid propulsion systems.)

MMC is the pioneering manufacturer in the field of mass-produced electric vehicles. The company launched the i-MiEV new-generation electric vehicle to the Japanese market in July 2009 targeting corporate, government and local authorities. In April of this year MMC started sales of i-MiEV to individual owners. The EV is the ultimate eco-car because its zero CO2 tailpipe emissions allow it to effectively address such environmental issues as air pollution, global warming and the shift away from oil. By adding a light commercial vehicle to its EV lineup – which, unit for unit, clock longer life-cycle driving distances than passenger cars – MMC is aiming to do its part to quickly make possible a low-carbon society.

Yamato Transport has been studying the use of commercial EVs which, of all next-generation vehicles, hold high promise for making possible a low-carbon society, and together with MMC, which has been pushing ahead the development and manufacture of electric commercial vehicles, has agreed to work in conducting a program of collection/delivery field tests using a light commercial EV.

*Modal shift: the shifting of road transport to rail and sea in order to reduce traffic congestion and environmental pollution.

2. Field testsFor the purpose of the field tests, the two companies will employ a prototype light commercial EV based on the Minicab market model but powered by the same EV powertrain and components as used by the i-MiEV. The gathering and analysis of a wide range of driving data and information through this program will allow the companies to ascertain the feasibility of using light commercial EVs in collection/delivery operations.

Beginning on October 15, the field tests will be conducted from Yamato Transport’s Higashi Kojiya 1-chome Depot in Ota-ku, Tokyo and will cover collection/delivery operations throughout the Ota-ku region.

3. Future prospectsYamato Transport views the start of these field tests as a major step in putting more next-generation vehicles on the roads in the transport industry as a whole. The company has already introduced 10 i-MiEV electric cars for the purpose of training drivers in the areas of safety and eco-friendly driving habits. On the basis of the results stemming from the field tests the company will also be looking at the use of light commercial EVs in its collection/delivery operations as part of its drive to make commercial vehicles eco-friendly.

For its part, MMC will feed back the field test results into its product development as it aims to bring a light commercial EV to market as early as possible.

This paper explores the challenges Video Encoder (MPEG, JPEG, WAVLET Compression) Equipment Manufacturers face when assessing video quality. Assessing video quality ultimately depends on the customer’s reaction on their new display (PC, POD, TV, etc.).

For visual and audio data, some loss of quality can be tolerated without losing the essential nature of the data. By taking advantage of the limitations of the human sensory system, a great deal of space can be saved while producing an output which is nearly indistinguishable from the original. These lossy data compression methods typically offer a three-way tradeoff between compression speed, compressed data size and quality loss.

The question must be asked. How much data can be removed before the customer has a violent reaction. So testing is increasing important. The test setup simply stated is
* Start with a known video sequence.
* Compress the video sequence.
* Decode the processed video sequence.
* Capture the processed video sequence.
* Display the original and processed video sequences.
* Bring in experts to subjectively vote.

Complexity arises as
* New Video Processing systems may need new equipment to playback the video sequences.
* The original and processed video sequences should be displayed in random orders.
* Expert viewers are expensive and do not produce repeatable results.

So a need arises to perform quantitative, repeatable objective scoring of the video.

Previous Options
Each vendor builds unique test equipment to verify their new algorithms. So the first job is to debug the test equipment before it can be used to verify a new design. Debugging the test equipment can take as long if not longer than debugging the display equipment.
Easier Solution
To streamline the process, equipment for video quality testing needs to be defined, which can capture, play, and analyze any two video sequences. Further, as new input/output modules are continuously under development, the test equipment should use an open-architecture approach to ease upgradeability.

Video Clarity defined the ClearView product line with these objectives in mind.
* Capture video sequences in as many formats as possible.
* Convert all video sequences to user-selectable resolution.
* Translate all video sequences to uncompressed Y’CbCr 4:2:2 or RGB 4:4:4.
* Support 8 and 10-bit data paths with upgradeability to future 12-bit modes.
* Store the video sequences as frames (fields) so that they can be played at any rate.
* Display the video sequences in real time in multiple viewing modes.
* VTR controls – play, shuttle, jog, pause
* Integer-based zoom & pan.
* Apply objective metrics to the video sequences.
* Export pieces of video sequences to further analyze off-line.
* Use a standard operating system so that the operator can run 3rd party analysis applications.

To further simplify the work flow, any video sequence can be played; while capturing another video sequence, thus, combining the video server and capture device into one unit. By doing this, the original source is already inside the test equipment so captured content alignment is easily obtained.

The original and processed video sequences can be displayed – side-by-side, mirrored, or seamless split – on a single display. This eliminates the need to calibrate two separate displays.

ClearView applies various objective metrics to the video sequences, generates graphs, and calculates an objective score. ClearView includes PSNR, Spatial Information and Temporal Information (as proposed in ITU-T P.9210). These metrics are the basis for more sophisticate metrics like VQM, JND, which are being analyzed by organizations like VQEG, VPQM, and SMPTE.

ClearView displays multiple video sequences, even if they are played at different rates (i.e. mobile phone video compared to TV) for the expert viewers; while recording the objective metric scores. While the MOS cannot be repeated, the objective metric can, easily and readily.

Since the system is based on an open, Windows-based architecture, any objective measurement algorithm can be modeled off-line using the stored video sequences.

Benefits
* Repeatable tests, quantitative results, and a streamlined setup.
* Analyze 2 video sequences in real-time up to 1080P.
* Input virtually any file type or capture from any digital or analog source.
* Multiple viewing modes are presented on a single display – no need to calibrate 2 separate Television displays to compare video sequences.
* Integrated uncompressed, high definition Video Server and Capture Device.
* Ability to Play 2 fully uncompressed, HD Streams in Real-Time.
* Hybrid Solution with Integrated Objective Metrics and Subjective Viewing Modes.

Case Examples
In all of the following examples, the tests can be performed using software mockups of the actual hardware unit. ClearView exports video sequences as files and accepts video files as inputs.

An Encoder manufacturer needs to
* Source for their video processing or encoders in SDI, Component, or DVI.
* Capture the output of their unit.
* Capture the output of their unit after it has been decoded.
* Visually inspect the new algorithm compared to the original and/or previous algorithms.
* Generate a Score for repeatability.

Summary
ClearView takes advantage of the high-reliability of today’s off-the-shelf computer platforms. This ensures that products are made with state-of-the-art hardware, while at the same time avoiding the high cost of custom designs.

ClearView provides broadcasters, video researchers, compression developers with the unique ability to capture, play-out, and analyze video sequences. Objective measurements are generated and logged for repeatable tests.
