Description

The DVDPlayer 4 MOST uses a multimedia processor OS8805. This chip communicates with the MOST network and its built-in firmware controls the DVD module as well as the MPEG encoder circuitries without any glue logic. Even the parallel bit stream port of the MPEG encoder interfaces directly to the DSP0's external memory port. A fiber optic unit for MOST network interface and an external industry standard I²C EEPROM for parameter storage along with a clock reference device and a power supply completes the setup.

DVD Module

An I²C-controlled automotive DVD module is used for accessing and decoding a broad range of media. The DVD module includes the drive mechanics and a single-chip DVD processor. The software driver for the DVD module is included in the OS8805 multimedia chip.

MPEG Encoder

An RS232-controlled MPEG encoder is used to scale audio and video data delivered by the DVD module. The scaling is adjustable. All common MPEG1 and MPEG2 formats can be selected for output on the MOST network. The firmware supplied with the OS8805 multimedia processor includes a software driver for the MPEG encoder and it features additional VideoCD_2.0 scrambling for MPEG1 data in DSP.

Flash Handler

The DVDPlayer 4 MOST has the capability of being re-flashed remotely over the MOST network. A flashing tool is available for programming the player using an OptoLyzer Interface Box, a MOST Tool Kit (a MOST PC Card or a MOST PCI Board) from SMSC.

Available Outputs:

• Analog composite CVBS (direct output)
• MOST PCM Audio
• MOST VideoCD_2.0
• MOST MPEG1 System Stream
• MOST MPEG2 Program Stream
• MOST MPEG2 Transport Stream
