Resolution This relates to the display size/resolution used by the incoming video stream.
• Available resolutions: D1 (default) or SIF:
• D1 is a resolution standard. In the NTSC system, "Full D1" means 720x480 pixels @ 30
fps, and in PAL systems, full D1 is 720x576 @ 24 fps.
• SIF (Source Interchange Format) is a resolution standard defined as 352x240 @ 30fps for
NTSC and 352x288 @ 24 fps for PAL.
Scaling This is the ability of the Modero panel to scale the incoming NTSC or PAL video stream into the
following pixel resolutions:
•NTSC format:
- 12" VG Modero panel: 360x240 (SIF),720x480 (D1), and 800x600
- 15" VG Modero panel: 1024x768
- 17" VG Modero panel: 1280x768
• PAL format:
- 12" VG Modero panel: 360x288 (SIF),720x576 (D1), and 800x600
- 15" VG Modero panel: 1024x768
- 17" VG Modero panel: 1280x768
Audio: This read-only field displays the audio streaming information (Audio Streaming format, sampling
rate, and number of channels).
• The properties of this incoming (detected) audio stream is given as: Audio Codec,
Sampling Rate, and Audio Channels.
• An example would be: MP3 44100Hz 2Ch. This means that the accompanying audio
stream is using a 2 channel, MP3 audio stream with sampling rate of 44100 Hz.
Codec Supported audio codecs: AAC, MP2 or MP3
• AAC (Advanced Audio Coding) is a digital audio encoding and loss compression format.
AAC was designed as an improved-performance codec relative to MP3 (which was
specified in MPEG-1) and MPEG-2 Part 3 (which is also known as "MPEG-2 Audio" or
ISO/IEC 13818-3).
• MP2 (MPEG Audio Layer-2) is used as a file extension for files containing audio data of
this type. It remains a dominant standard for audio broadcasting. This file type allows the
coding of audio programs with more than two channels. The main difference between
these two types is that MP2 audio files are generally larger than their MP3 counterparts
and are mostly used with MPEG-2 video streams.
Note: MP2 is recommended for use with a high bandwidth video stream (ex: MPEG-4 or 6
Mbps - 3 Mbps).
• MP3 (MPEG Audio Layer-3) is a popular digital audio encoding and loss compression
format. It was designed to greatly reduce the amount of data required to represent the
original audio data, yet still sound like a faithful reproduction of the original uncompressed
audio to most listeners.
Note: MP3 is recommended for use with a low bandwidth video stream (ex: MPEG-2 or < 3
Mbps).
Sampling Rate This is the sampling rate used by the incoming audio stream.
• Sampling rate defines the number of samples per second taken from a continuous signal
to make it a discrete signal.
• Rate is measured in KHz (KiloHertz).
• Available audio sampling rates: 32KHz, 44.1KHz, and 48KHz.
• Some of the common uses for these rates include:
- 32,000 KHz - miniDV digital video camcorder
- 44,100 KHz - compact disc, also most commonly used with MPEG-1 audio (VCD, SVCD,
MP3)
- 48,000 KHz - digital sound used for digital TV, DVD, DAT, films and professional audio
Note: Currently, 32KHz is not supported within the Modero firmware.
Audio Channels The number of audio channels encoded within the incoming audio stream.
• Modero only supports 2CH (2 channel) audio.
Brightness: Use the UP/DN buttons to alter the brightness level of the incoming signal.
• Range = 0 - 255, default = 128.
