Description
The ZL10320 is a DVB-T PVR-on-a-Chip solution which enables the rapid development of cost effective and
feature-rich DVB-T based Personal Video Recorders (PVR). To achieve this, Zarlink has integrated two DVB-T
compliant COFDM demodulators, an MPEG-2 audio/video decoder, a PVR controller and a full suite of set-top
box/iDTV interfaces together with a high performance CPU into a single System-on-a-Chip (SoC) solution.
The ZL10320's PVR Controller can sustain the simultaneous transfer of three MPEG-2 Transport Streams with a
hard disk drive, permitting, for example, simultaneous recording of two TV Channels and playing-back a third;
essentially three VCRs in a box. The key capability of PVR technology is the ability to live-pause and time-shift live
broadcast television, where a recorded stream can be played back before its recording has completed. The
ZL10320 supports this function, and in addition allows the simultaneous recording of a second digital channel. This
is made possible by high-performance on-chip DMA controllers, which transfer bitstreams between the PVR
Controller, SDRAM and IDE Hard Disk(s) efficiently, with minimum CPU overhead.
PVR functionality places considerable demand on the software environment, which necessitates that such systems
are based on robust multitasking operating systems, supporting virtual memory and memory management. Linux,
with its wide range of capabilities is ideally suited for such applications. Consequently the ZL10320 uses the high-
performance PowerPC 405 RISC processor, which fully supports the requirements of the Linux Operating System.
The ZL10320 is able to share a common Linux Code base at the device driver, middleware and application layers
with the entry-level ZL10310/ZL10311 solutions, which are also available from Zarlink Semiconductor.
Also available is the ZL10321 DVB-T PVR-on-a-Chip, which additionally offers Dolby
Digital

decoding, and Macrovision

Copy Protection for applications requiring Dolby
Audio and Pay TV services.

General purpose individual bit I/Os
If not required in a particular system, any of the peripheral interfaces can be replaced by individual I/O bits from
internal general purpose registers. These can then be used for additional purpose, such as interfacing to switches
and displays.
Typical Applications
Free-to-Air Terrestrial PVR Receiver
Figure 2 on page 3 shows a typical Free-to-Air DVB-T compatible Terrestrial DTV PVR receiver block diagram
employing a ZL10320 device. In its minimal configuration, the ZL10320 requires two 64Mbit SDRAM devices, an
audio DAC, a Flash ROM, two Terrestrial Tuner Blocks (Zarlink can provide reference designs for modular tuners
and 'tuner-on-motherboard' solutions), a dual multiplexed 10-bit analog to digital converter and an IDE Hard Disk
Drive.
The compelling capability of PVR technology is the ability to live-pause and time-shift live broadcast television,
where a recorded stream can be played back before its recording has completed. The ZL10320 extends this
capability by additionally offering the ability to simultaneously 'Pause-Resume' on one TV channel whilst recording
a second TV channel.

The Terrestrial Tuner sections perform an independent down conversion of the received DVB-T signal from the
Antenna, to an IF frequency in the range of 30MHz to 57MHz, dependent on television system (typically 36.17MHz
Center Frequency, with
4MHz span). The analogue IF is then converted to the digital domain, with a 10-bit ADC,
clocked at 20.48MHz and the resulting Digital output is centered on 15.69MHz. This Digital signal is applied to the
ZL10320 via the ADC_IN[9:0] input pins, in the form of a 10-bit parallel signal.
The ZL10320 converts the digitized IF from a Terrestrial TV Tuner into an MPEG-2 Transport Stream, which can be
optionally de-scrambled (if CA scrambling is used by the broadcaster), and de-multiplexed into separate Packetised
Elementary Streams (PES), which are routed to the MPEG Audio and Video decoders, and SI data to the PowerPC
405
TM
subsystem. The PVR controller block contains an additional 64 level PID filter for the efficient selection of
the desired programme for recording.
Decoded Video can then be mixed and optionally scaled with On-Screen Display (OSD) Graphics generated by the
DTV application software. The resultant combination of video and graphics are then routed to the PAL/NTSC Digital
ENCoders (DENCs) for display on the TV via the on-chip 10-bit video DACs. The Video DACs can then produce
Analog Video in either Composite Video (CVBS), or Component Video (RGB or YPrPb).
Decoded Audio is output directly from the audio decoder sub-system to the I
2
S (Inter IC Sound) and S/PDIF
(Sony/Philips Digital InterFace) outputs.
The Decoded Audio and Video from the ZL10320 can either be provided via standard Analogue Video and Audio
connections to a Television Monitor, or can be used to provide the inputs to a UHF re modulator to provide a UHF
Analogue Television signal to connect to a standard analogue TV.
Free-to-Air Dual-Standard Terrestrial and Satellite PVR Receiver
The ZL10320 can be used to implement multi-standard DVB receiver with the addition of external demodulator
devices. Figure 3 on page 5 shows the block diagram of an example application of a dual-standard dual-channel
selectable Satellite and Terrestrial PVR receiver. Zarlink Semiconductor's Satellite Tuner technology allows for the
DVB-S and DSS Satellite television standards to be received. With the advent of Free-to-view satellite services in
some countries, this concept has potential applications in regions where some TV services are available only on
one or other standard (Terrestrial or Satellite) but not both.
