LITE-ON BD B LH-2B1S Blu-Ray Drive


1. Introduction

LiteOn recently released its first Blu-ray drive, the LH-2B1S. Leveraging the support and technology of the Philips / BenQ joint venture, the Taiwanese company released the drive in a market which currently appears to be considering the Blu-Ray technology as "premium", and more suited towards professional users.

LiteOn's BD burner differs from the rest of BD drives appearing on the market by the fact that it comes with a S-ATA interface, making it ideal for the majority of the latest motherboards and offering easier connection to the PC system. Of course, the main strengths of the drive remain its specifications, which include support for all CD/DVD and Blu-Ray formats.

Writing speeds for the LiteOn BD drive are set at 12X for DVD±R, 4X for DVD±R DL and 32X for CD-R. The drive does not support the DVD-RAM format; a feature that found in the other first generation LG and Panasonic-based Blu-Ray drives (Plextor, Sony). However, it is the fastest when it comes to writing speeds for the "traditional" CD and DVD formats. But the most important thing is the 2X writing and reading speed for single layer BD-R and BD-RE media formats.

What is very interesting is the fact that the drive does not support reading or writing of dual-layer Blu-Ray discs. Most of our readers would expect this feature, especially considering that the corresponding drive from BenQ (BW1000), which practically shares the same technology, is expected to offer BD-R DL burning (1X) through a firmware upgrade. LiteOn has hinted that there will be no such a possibility with its LH-281S drive, claiming that it is a limitation of the current hardware.

At a glance, the basic features of the drive include:

In order to play HD content titles, a compatible HDCP monitor or HDMI TV set is required. While a number of graphics cards claim to be HD compatible, it is not always the case and there are still some issues involved. Certainly, the latest graphics drivers need to be downloaded from nVidia and ATI. Finally, region control has been implemented, similar to that used with DVD titles, so the correct region must be set. In addition, HDCP-capable play-back software is also required.

 

 

Bundled in the retail package, LiteOn offers a complete software suite, including the following:

Cyberlink BD Solution Power DVD Playback BD/DVD
PowerProducer Video Editing and Authoring
Power2Go Back up your files, create audio CDs and burn CDs/DVDs/Blu-ray Discs(BD), drag and drop operation.
PowerBackup PC backup solution. It analyzes, sorts, and archives files onto a hard drive, disc, or removable storage media. Supports CD/DVD burners.
InstantBurn Burning
Cyberlink BD/HD Advisor Checks whether the your PC configuration is suitable for Blu-Ray playback
Quick User's guide
SATA data cable
1 TDK BD-RE blank disc
Mounting screws

What's interesting in the drive's front panel, is the activity LED, which indicates the drive's operating status. When the LED is on, the disc is loaded and ready; when blinking, the drive is reading / writing / rewriting or the disc is loading. The LED lights up blue, red and green when a BD, DVD or CD respectively, is loaded.

A typical rear view, for a SATA optical disc drive. The 15-pin connector for DC power input (Serial ATA Power Connector) and the 7-pin connector for Serial ATA data interface (Serial ATA Data Connector) are present, as you can see in the image below.

Our test sample was manufactured in October 2006 in China.

The drive is built around the Philips Nexperia PNX7866EL chipset, an all in one chipset supporting all CD and DVD media formats, except for HD-DVD. It also has an Arima Optical Pick-up Unit (OPU) and a Philips DSP chip.

Installation

The LiteOn LH-2B1S was installed as a typical SATA drive and was recognized as "LITE-ON BD B LH-2B1S".


2. CD - DVD Reading

For our CD transfer rate tests, we used the Nero CD-Speed utility and a set of Pressed CDs. The drive can read CD media at a maximum speed of 32X. For reference, we present a comparison of the LiteOn Blu-Ray drive with the LG GBW-H10N, Sony BWU-100A and Plextor PX-B900A drives.

Pressed CD

With its 40X maximum reading speed for CD-R/ROM, the LG drive is fastest in this task.

US RW CD

The following CD Speed graph shows the reading performance with US-RW media. For all the CDSpeed graphs, you can click on the image to see the full CDspeed snapshot.

Press for Larger Picture

- AudioCD

In the CD Speed Advanced DAE quality test, the drive's average speed was 24.70X with a quality score of 100.

A typical DAE task with an 80min non-protected Audio CD produced a 26.15X average ripping speed.

EAC's test for the drive's CD-ROM capabilities indicate that the drive does not support reporting C2 error information:


- 90/99 mins Audio disc

The 90min audio CD reading returned an error, as you can see in the screenshot above. On the other hand, the 99min audio CD was read, although the reading speed dropped sharply after the 92min mark:

In order to make certain of the drive's capabilities with the 99 min CD, we ripped the audio tracks from the disc onto the hard disc. Playing the last tracks produced interruptions and noise, indicating that the drive did correctly rip the full 99min contents of the disc.

- DVD Format

Now let's have a look at how the drive performs with DVD media. This time, a set of SL and DL DVD media was used. The drive is capable of reading at 12X maximum speed for single layer and at 8X for dual layer media.

DVD-ROM SL media -

PTP DVD-ROM -

The two layers of a PTP DVD-ROM disc are read sequentially with the drive starting reading from the inner part of the disc, which is the beginning of each layer, progressing towards its outer range.

OTP DVD-ROM -

The first layer of an OTP dual layer DVD-ROM is read exactly the same way as the first layer of the PTP disc we tested previously. The difference here is the reading strategy of the second layer of the disc. The beginning of the second layer is located in the outer part of the disc, so the drive starts reading from the outer tracks and progresses towards the inner part of the disc.

- DVD-R /-RW

A 12X CAV reading strategy for DVD-R and DVD-RW media:

- DVD+R /+RW

- DVD+R DL

-DVD-R DL

- DVD Ripping speed

Ripping a DVD-Video title to the hard disc is fastest for the LiteOn drive.

Average - 7.527 KB/S (5.4x)
Maximum - 10,375 KB/s (7.5x)


3. CD Error Correction

In the following tests, we check the drive's behavior when reading scratched / defective audio discs. The test discs used were the ABEX series from ALMEDIO.

- ABEX TCD-721R

For this test we could not perform the usual ripping task through the EAC software suite, since the CD ripping task would require some hours, and it would most probably not finish at all. The LiteOn LH-2B1S slowed down reading at 0.2X as soon as it reached the audio tracks that were placed in the "scratched" areas of the disc. Such a behavior could turn out to be of a profit for the end-users, since the drive would slow down reading in order to correctly read/rip their damaged disc. In our case, the drive read the contents of the demanding ABEX TCD-721R audio CD, as you can see in the corresponding CDSpeed test:

- ABEX TCD-726

Errors total Num: 0
Errors (Loudness) dB(A) Num: 0 Avg: -174.0 dB(A) Max: -174.0 dB(A)
Error Muting Samples Num: 0 Avg: 0 Samples Max: 0 Samples
Skips Samples Num: 0 Avg: 0 Samples Max: 0 Samples
Total Test Result 100.0 points (out of 100.0 maximum)

On the other hand, the drive ripped the ABEX TCD-726 test disc accurately. A perfect score for the LiteOn drive, which seems to be ready to handle the specific disc defects, which are artificial black dots and fingerprints.

- CD-Check Audio Test Disc

The CD-Check Test Disc is a very useful tool for evaluating the Sound Reproduction / Error correction capabilities of a CD player. The disc offers a signal combination with disc error patterns to rate the drive's abilities to read music and reproduce it completely. Five tracks on the disc contain a sequence of progressively more difficult tests. These tracks are referred to as Check Level-1 through Check Level-5.

The tracks are reproduced through a software multimedia player (e.g. Windows Media Player). Each level is considered as passed, if the tone is smooth, continuous without interruptions, skipping or looping. The higher the Check Level passed, the more reliable the sound reproduction of the tested drive.

Error Level
1
2
3

The drive achieved flawless reading with the first 4 tracks. Playing the fifth track gave back audible sound interruptions and clicks.

- Summary

Overall, the drive appears to have good CD Error correction capabilities.


4. DVD Error Correction

In the following tests, we examined the DVD reading capabilities of the drive with scratched / defective DVD media. For the tests, we used CDVD Benchmark and Nero CDSpeed. The reference test media comes from ALMEDIO.

- Single Layer media

ABEX TDR-821

This is a single sided, single layer DVD-ROM with a 4.7GB capacity, and its surface has an artificial scratch of dimensions varying from 0.4 to 3.0 mm.

The following transfer rate picture comes from the CDVD Benchmark v1.21 transfer rate test.

Respectable reading with no read errors from the LiteOn drive.

ABEX TDR-825

This is also a single sided, single layer DVD-ROM of 4.7GB capacity. The data structure of the disc is exactly the same as that of the TDR-821, with the difference that there are no scratches on it but instead, defective areas of dimensions ranging from 0.5 to 1.1 mm.

There are also fingerprints sized between 65 and 75 micrometers.

No issues for the LiteOn LH-2B1S drive, continuing its good performance:

- Dual Layer media

ABEX TDR-841

This is an 8.5GB dual layer, single sided DVD-ROM disc with artificial scratches of dimensions ranging from 0.4 to 3.0mm, on both layers.

ABEX TDR-845

The disc is a single sided, dual layer DVD-ROM disc with a capacity of 8.5GB. The only difference between the TDR-845 and the TDR-841 is that the first includes defective areas and fingerprints.

The dimensions of the defective areas range from 0.5 to 1.1 mm and the fingerprints are sized from 65 to 75 micrometers.

ABEX TDV-541

The TDV-541 is a single sided, dual layer DVD-VIDEO disc, with a capacity of 8.5GB.The disc is based upon the TDV-540 series which is designed for inspection and adjustment of DVD-VIDEO players. The disc checks the layer switch operation from layer 0 to layer 1 and also includes test pictures and test signals for DVD sound files.

The current TDV-541 also checks the error correcting capabilities of the drive and includes scratches from 0.4 to 3.0 mm.

There were no errors and the drive read the disc flawlessly at 8X CAV.

ABEX TDV-545

The TDV-545 disc is based on the TDV-540 series. It is a single sided, dual layer DVD-VIDEO disc with a capacity of 8.5GB.

The TDV-545 includes artificial black dots on the data surface, sized from 0.4 to 1.0 mm. It also has 65 - 75 micrometer fingerprints.

- Summary

Overall, excellent error correction mechanism with DVD media.


5. TDK CDR

As a side-note, the LiteOn LH-2B1S supports 32X P-CAV maximum burning speed, using a power calibration function that runs in real-time, during the actual burning process.

For this test, each CD-R disc was burned to its maximum capacity and at its maximum speed. Then the same disc is read with the CDSpeed software, and the disc was scanned for digital errors (BLER, C1 and C2) with our system provided by Clover Systems. To simplify the presentation, we present the BLER, E31 and E32 error rates for each disc, which unveil the most serious errors on each disc.

Writing Quality - Clover Systems

A good overall writing quality, with low E31 and zero E32 (uncorrectable) errors. The E12 flag is out of limits, but these kinds of errors are correctable.

- About Clover Systems

The Clover Systems CDX Compact Disc Analyzer is a tool to quantitatively measure the quality of a CD. It will analyze CD-DA, CD-ROM, CD-ROM XA, CD-I, CD-R, Photo-CD, Enhanced CD and CD-RW discs at 4X, 8X, 24X, 32X or 40X speed. It effectively measures disc quality by examining the quantity and severity of CIRC errors generated during playback. It also provides the capability to measure signal parameters related to pit geometry, such as asymmetry and reflectivity. Together, all these bits of information provide a thorough analysis of disc quality. The Clover Systems Analyzers can also perform various format-checking tests on data discs, and do bit-for-bit data comparison on all types of CDs. All tests are carried out at the speed of 4X.

CIRC error correction uses two principles to detect and correct errors. The first is redundancy (extra information is added, which gives an extra chance to read the disc), and the second is interleaving (data is distributed over a relatively large physical area). The CIRC error correction used in CD players uses two stages of error correction, the well known C1 and C2, with de-interleaving of the data between the stages.

The error type E11 means one bad symbol was corrected in the C1 stage. E21means two bad symbols were corrected in the C1 stage. E31 means that there were three or more bad symbols at the C1 stage. This block is uncorrectable at the C1 stage, and is passed to the C2 stage. Respectively, E12 means one bad symbol was corrected in the C2 stage and E22 means two bad symbols were corrected in the C2 stage. E32 means that there were three or more bad symbols in one block at the C2 stage, and therefore this error is not correctable.

BLER (Block Error Rate) is defined as the number of data blocks per second that contain detectable errors, at the input of the C1 decoder. Since this is the most general measurement of the quality of a disc, you will find BLER graphs for all media tested below. If you click on the images you can see a more detailed table, indicating error levels. The Red Book specification (IEC 908) calls for a maximum BLER of 220 per second averaged over ten seconds. Discs with higher BLER are likely to produce uncorrectable errors. Al low BLER shows that the system as a whole is performing well, and the pit geometry is good. However, BLER only tells us how many errors were generated per second, and it does not tell us anything about the severity of those errors.

There are three measurement modes:

The checking status is shown graphically in real time while you can save the error graph at the end of the test. The reported errors are the PI and the UncPO. In the case of PI, it counts the number of rows corrected by the PI error correction in each group of eight consecutive ECC blocks. In the case of UncPO, it counts the number of ECC blocks in which more than one byte is uncorrectable in eight consecutive ECC blocks. For our quality scans, we set for 1X CLV and Fine Mode which is the slowest and with the safest results. Also, we chose to measure all the media burned at the maximum available writing speed.

53. Conclusion

LiteOn's first generation Blu-Ray drive has left us with a good overall impression, showing an overall positive behavior in the basic tasks of this review.

As a Blu-Ray drive, the device successfully burned all the BD-R and BD-RE media we used in this test. Having compatibility in mind, we tested the burned discs in the other Blu-Ray drives that are currently available on the market. All discs were readable except for the TDK 50GB BD-R disc, which is not supported by the drive. Early announcements of the LiteOn LH-2B1S drive indicated that the drive would be compatible with dual-layer (50GB) BD-R media but currently, the company claims that hardware limitations do not allow this kind of support, while it promises it in the next generation of drives.

How about using the drive as a Blu-Ray movie player? Unfortunately, we were unable to test any titles with the drive, since as yet, no releases have been forthcoming in the European region. But the drive is only one link in the chain of devices required to play a HD title. As it is widely discussed over the internet, in order to play HD content titles, a compatible HDCP monitor or HDMI TV set is required as well as an appropriate graphics card (HDCP) and the latest Nvidia or ATI drivers.

The drive is very fast with the more traditional CD and DVD media in either writing or reading. The supported 12X writing with DVD±R media provides the drive a small edge compared to the other Blu-Ray drives currently on the market, as well as the 32X speed for CD-R.

In our suite of tests, the drive proved a very capable reader with both CD and DVD defective media. With burning CD and DVD media, it provided adequate quality, probably in part due to the fact that burning was done at lower speeds. However, some MIDs were not supported by the drive, making the specific discs unreadable. In some other cases, the drive refused to complete a burning session. But all these issues may be fixed through a firmware release, so we expect that LiteOn will update the drive soon.

All in all, the LiteOn LH-2B1S could be an attractive triple-format Blu-Ray burner for all those who are willing to pay US$545-699 (according to online prices).
