1 Introduction to the DTS Audio Format Several major consumer audio formats that exist today are listed in this table: Note 1 - All formats require decoders, except Stereo and THX. THX is not a processing system but an audio/video quality control approval system. Its certification stamp means that the video and audio quality at theaters and CD/DVD [...]

2 What is DTS? Digital Theater Systems has developed a digital audio compression method similar to Dolby Digital AC-3. DTS processed audio is not as compressed as Dolby AC-3. Therefore it is said to have more surround detail (separa- tion), envelopment and better bass because of less compression (losses). What do I need to play the DTS surround for[...]

3 Why won’t my older DVD player play DTS DVDs? The DVD DTS flag was not established until Nov 1998. This flag must be inserted into the DVD’s digital coax or optical output for the receiver to recognize and decode DTS. Therefore DVD units that are not marked “DTS ready” will not play DTS even though they have digital outputs. Can DVD movies[...]

4 Global Bit Management Once compression has taken place, an examination of the six data streams for density is made. Bit groups are tagged and moved from a high-den- sity channel to a low-density channel equalizing the amount of data. 0011100011000011111001010101 channel 1 0000001011000000000000000000 channel 3 Variable Length Coding Common fixed [...]

9 Video and Audio Processing After the servos have begun, RF data will come from the optical assembly within the base unit. The “eye pattern” RF data is split into two paths to provide: 1. Feedback signal to lock the servos; and 2. Video and audio information. In the A/V processing chain, the RF data is processed by the following ICs: Audio / V[...]

49 KHM-220A DVD Optical Block Sony DVD players had two independent laser assemblies. One was used to play DVD and the other used to play CDs. In 1999, a single DVD laser in the KHM-220A block was used to play both discs. There were two additional G & H photo detectors added to the optical assembly, but they are not used. By examining disc focus[...]

55 Focus Mechanical focus of the laser beam on the information layer of the disc is accomplished by moving the laser’s objective (final) lens closer to or away from the disc. Applying a current to a coil that is attached to the lens controls the lens position. When the lens moves up and down, so does its corresponding focus point at the disc area[...]

61 Spindle Motor The spindle motor has a “kick” mode and a run mode. The kick mode is used to start and stop the motor, bringing the motor up to speed or to a stop quickly. The CLV PB mode utilizes the pits on the disc surface to regulate the spindle motor speed. Kick Mode IC202 issues the kick command to start or stop the spindle motor. After-[...]
