1.1 General Description
ZR36778
The Vaddis 778 can control disc loaders and read bitstreams using the following media:
DVDROM, DVD-R, DVD+R, DVD-RW, DVD+RW, CDDA, CD-ROM, CD-ROM (XA),
CD-R and CD-RW discs.
The Vaddis 778 can playback all discs conforming to the above standards (including support of
sub-pictures, highlights and closed captions) with the exception of DVD-Audio ASV transition
effects. The Vaddis 778 can playback MP3 (MPEG 1 Layer 3), MPEG 2, Layer 3 (including
low sampling rates) DTS, AAC or WMA type audio files from CD-ROM, CD-R and CDR/ W
discs. The Vaddis 778 can playback various types of JPEG, MPEG 4 and DivX bitstreams from
files on DVD-ROM, DVD-R, DVD-RW, CD-ROM, CD-R and CD-RW, or on flash cards, or
SACD with external SACD decoder chip.
It is assumed that the reader is familiar with the various discs, JPEG, MPEG 4, MPEG 2 and
MPEG 1 international standards and the industrial standards for DivX, DVD-Video, DVDAudio
and the various types of CD and flash card formats.
The Vaddis 778 receives data from the disc loader optical pick-up unit OPU through an
external RF amplifier, limit switches and other sensors and control the disc loader focus and
tracking coils, sled, spindle and tray motors through a servo amplifier external device(s). The
Vaddis 778 implements all the signal processing, multi-pass ECC, EDC, track buffer
management and servo functions that result in a (error corrected) bitstream.
The Vaddis 778 can perform the decryption processes for bitstreams originating from a DVDVideo
or DVD-Audio discs or from DivX bitstreams.
The max data read rate for all types of CD discs is 8x (8*1.411 Mbits/Sec). The max data read
rate for DVD discs is 2x (2*10.08 Mbits/Sec).
The Vaddis 778 outputs interlaced or progressive CCIR size (also called SD or D1 size), 4:2:2,
Y, U and V digital video. The representation of each component sample is 8 bits. Suitable post
processing , to transform the original decoded size and format (e.g., SIF size or CCIR size
MPEG 1 format, SIF size, "half D1" size, "2/3 D1" size or CCIR size MPEG 2 format) to the
interlaced CCIR size, 4:2:2, Y, U and V format, is performed by the Vaddis 778.
The interlaced video display frame rate is either 25 or 29.97 frames per second. Frame rate
conversion is performed from coded MPEG frame rates of 23.976, 25, or 29.97 per second, to
one of the two display frame rates mentioned above. For example, for display frame rate of
29.97 and coded frame rate of 23.976, "3/2 pull down" is performed.
The progressive video display frame rate is either 50 or 59.94 frames per second. Frame rate
conversion is performed from coded MPEG frame rates of 23.976, 25, or 29.97 per second, to
one of the two display frame rates mentioned above by a de-interlacing unit using 2 fields edge
adaptive interpolation.
The interlaced or progressive 8 bits digital video output is synchronous with an output video
clock and sync signals, and contiguous along each video line.
Image display "location" relative to the sync signals, and size (up to the max specified above),
are specified by Vaddis 778 SW. The size of the displayed part of the decoded image can be
less than or equal to the size of the decoded image Format conversion between PAL, NTSC,
16:9 or 4:3 is supported, with pixel aspect ratio conservation, using (e.g.) either the "Pan-scan"
or the "Letterbox" methods.
When the digital video output is interlaced, the Vaddis 778 output analog interlaced video
through a video encoder and four 10 bits DACs that are included in the Vaddis 778. Analog
outputs can be either composite (CVBS and Y, C of “S-video”) or component (R, G and B, or
DVDROM, DVD-R, DVD+R, DVD-RW, DVD+RW, CDDA, CD-ROM, CD-ROM (XA),
CD-R and CD-RW discs.

When the digital video output is interlaced, the Vaddis 778 output analog interlaced video
through a video encoder and four 10 bits DACs that are included in the Vaddis 778. Analog
outputs can be either composite (CVBS and Y, C of “S-video”) or component (R, G and B, or
Y, U and V). When the digital video output is progressive, the Vaddis 778 output analog
progressive video in components format only, through the three components DACs or
compatible interlaced video. The video encoder and DACs operate with a 54 MHz clock.
The audio output is 16, 18, 20 or 24 bits, two to eight channels, PCM samples at 16, 22.05, 24,
32, 44.1, 48, 96 or 192 KHz with each pair of (e.g., left and right) samples interleaved on a
serial bus according to several flavours of the I2S standard. Post processing of the decoded
audio and one stereo digital audio input, suitable for Karaoke and similar applications is
supported.
Audio coded data or reconstructed data can be output on a single line using an internal S/PDIF
transmitter. PCM or coded audio data can be also input through one of two S/PDIF (TTL)
inputs using a S/PDIF receiver to recover the input bit clock.
The Vaddis 778 can also output 8 bits, Y, U and V, 4:2:2, digital (“still”) video to the
HDXtreme companion chip, in various formats, compatible with the HDXtreme, as long as the
sample rate is less than 135 MHz and the width of the Y component is less than 2047. In this
mode, no other digital or analog video is output.
The Vaddis 778 uses Synchronous DRAMs (SDRAM) for external buffers and generates all
address and control signals for this external buffer. The required Synchronous DRAMs are of
- 7 type (max clock rate of 147 MHz). The required size is 64 Mbits using one 4M*16 bit
device. The internal structure of the devices has to be four banks of 2048 rows by 256 cells
each.
Some limited applications can be supported by a single or dual 16 Mbits device(s). A single
128 Mbits device with four banks of 2048 rows by 512 cells each is also supported.
The Vaddis 778 interfaces to the other devices of a player (e.g., IR remote control receiver,
front panel controller, audio DACs and ADCs) mainly through GPIO functions controlled by
SW to implement protocols like SPI and I2C. There are on-chip HW aids to interface to a
master SSC type device (e.g., a front panel concentrator).
