Key Feature Description
SuperVCD support
The ZR36215 provides full support for all the requirements of the
SuperVCD specification. This include MPEG2 video decoding for
2/3 D1 content, MPEG audio decoding, OGT, etc. In addition to the
SuperVCD support, the ZR36215 supports the VCD1.1 and VCD2.0
specification, thus enabling the development of a SuperVCD
systemwith full back compatibility with the existing VCD standards.
Karaoke
Karaoke is a popular feature for the Asia market. Karaoke features
are possible in the ZR36215, thus elimnating the need for an
external karaoke processor. Basic features of Karaoke are Voice
Cancellation, Echo, and Key Control. Voice Canceling is a feature to
elimnate the singers voice on a CD by filtering out the vocal
content, allowing you to sing along. The echo function provides the
effect of singing in a large auditoriumand slightly modifies the
singer's voice to enhance the sound. Key Control adjusts the pitch of
the music by quarter tones to allow the pitch of the music to be
shifted to match the pitch of the singer.
MPEG Video Decoding
High quality video is accomplished using MPEG-2 video encoding in
comparison to the VCD standard of MPEG-1 encoding. SuperVCD
encodes the video in MPEG-2 to achieve the higher quality in
comparison to VideoCD. The ZR36215 supports both MPEG-1 and
MPEG-2 decoding, thus supporting SuperVCD and VideoCD
requirements. Additionally, the ZR36215 support the decoding of
Variable Bit Rate (VBR) encoded content. VBR is an effective
method of increasing the video encoding efficiency of MPEG-2. The
more complex the video content, the more bits are allocated. For
simple video content, much less bits are allocated. VBR maximzes
the video capability for SuperVCD and thus achieves a higher quality
motion picture.
MPEG Audio Decoding
For higher storage capacity of audio data, MPEG audio encoding is
performed. For high quality audio, sampling rate of 44.1 or 48 khz
are used. MPEG-2 provides multi-channel capability in addition to
backwards compatibility to MPEG-1. MPEG-1, currently used for
VideoCD, provides mono or stereo audio outputs. The ZR36215
supports both MPEG-1 and MPEG-2 audio decoding with 44.1khz or
48khz sampled data.
Programmable DSP
The ZR36215 has an embedded 40 MIPS DSP which can performa
variety of post-processing audio algorithms. Music mode algorithms
enhance the existing stereo or multi-channel audio source and
provides various listening environments by affecting the delay, echo
and other key characteristics of the audio signal. 3D audio can
provide the effect of a multi-channel systemin a two speaker
environment. The ZR36215 can performthese operations in
addition to the Video and Audio decoding.
Multi-language support
The ZR36215 can support up to four languages as required by the
SVCD specification. Multi-language capability provides the ability to
view content in various languages as supported by the SVCD disk.
