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.
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).
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.
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.

11 Power Supply Block The power supply is on a single board located to the left of the DVD mechanism. This board contains both the standby and the main power supply. The input line filter L101 and the board connectors are the only parts that are not available.

21 Communications Block Both serial and parallel bus structures are used in the same unit of today’s DVD players. The serial data bus is a simple way to provide communica- tions between ICs. On one line, data is transmitted one bit after another to the next IC in 8, 16, 20, 24 or 32 bit groups.

23 Serial Data Communications A close examination of the serial bus structure shows there are two serial buses. Both are active as long as the set is ON.

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.
50 Three Laser Beams from One Laser Although there is one laser, there are three spots of light on the disc’s information layer. The three spots are made by diffraction grading inside the laser assembly.
51 Photo Detectors The three beams of light are reflected from the disc and returned to the optical assembly. They land on the photodetectors within these three groups.
52 NOTES.
53 Disc Identification DVD Player models DVP-S330, S530D, S550D and S705D identify the disc during focus search as the laser’s objective lens is rising. Photo detector group A-D in the optical assembly is used for this detection pro- cess. These detector outputs are matrixed by the RF amplifier IC001 to produce several outputs.

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.

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.

65 Tracking Servo The purpose of the tracking servo is to keep the laser beam positioned at the center of the disc’s data (stream). This is achieved mechanically by attaching a lightweight coil of wire to the laser’s objective (final) lens. This coil faces a stationary magnet.

69 Tilt Servo Operation The laser is mounted on a platform that pivots at the center and rests on an incline gear at one end. The tilt motor controls the incline gear and consequently the angle of the laser beam with respect to the disc.
