2.2 Product Application & Description
Application:
EQAM-420B (EdgeQAM with EAS)
is designed to allow CATV operators to aggregate multiple SDTV/HDTV programs
received in IP format and to deliver them over a standard coaxial distribution network.
The EQAM-420B is capable of accepting unencrypted
(clear)
UDP or RTP
streams in one of the following two modes:
SPTS Mode:
Accepts and processes up to sixty-four
(64)
MPEG-2/H.264 Single Program Transport Streams
(SPTS).
In SPTS
mode the EQAM-420B can select a maximum of any four
(4)
SPTS and multiplex them for transmission on QAM outputs
up to a maximum of 38.8 Mbps/QAM. Each SPTS can contain one
(1)
video and up to one
(1)
audio Elementary streams.
MPTS Mode:
Accepts and processes up to sixteen
(16)
MPEG-2/H.264 Multi Program Transport Streams
(MPTS)
. Each
MPTS is limited to a maximum of six
(6)
programs and not to exceed 38.8 Mbps/QAM. Each MPTS can contain one
(1)
video and up to three
(3)
audio Elementary streams.
The streams are aggregated in up to sixteen
(16)
QAM RF channels in the 54-1002 MHz range. The unit is configured with
four
(4)
QAM output modules, each capable of delivering four
(4)
adjacent QAM channels. Each QAM channel can contain
up to four
(4)
programs in SPTS mode and a maximum of 6 in MPTS mode.
The EQAM-420B supports network-based EAS program switching
(Soft/IP enabled Trigger)
based on the SCTE-18 standard.
Upon receipt of an appropriate SCTE-18 EAS trigger the system replaces all the video and audio programs with the EAS
messages. Therefore, all viewing locations will display both the video and audio EAS messages. An SCTE-18 conforming
TV or set-top box is not required.
The unit also allows the operator to maintain the QAM RF output unencrypted, or to encrypt it with Pro:Idiom™ against
content piracy. To utilize the Pro:Idiom™ encryption feature, the input streams must be received on a dedicated GbE
port and must meet the Pro:Idiom™ requirements. When Pro:Idiom™ encryption is activated, Pro:Idiom™ capable TV, or
external Pro:Idiom™ decrypter is required to view Pro:Idiom™ encrypted premium channels.
Comprehensive remote monitoring and control is accomplished using any standard Web browser via a front-panel
10/100BaseT Ethernet connection. Also, the unit provides system health information to a user maintained server via Syslog.
This is an extremely valuable tool for troubleshooting system related issues.
Features:
• SPTS Mode: Accepts up to sixty-four (64) MPEG-2/H.264 Single Program Transport Streams (SPTS); 1 video + 1 audio
per program
• MPTS Mode: Accepts up to sixteen (16) MPEG-2/H.264 Multi Program Transport Streams (MPTS), each MPTS
with maximum 6 programs and not to exceed 38.8 Mbps; 1 video + 3 audios per program
• Supports IGMPv2 and IGMPv3 protocols
• Configured with 4 modules, each with four (4) adjacent QAM channels, for a total of 16 QAM channels
• Provides network based EAS switching based on SCTE-18 (by program substitution)
• Comprehensive GUI-based menu for remote monitoring and control via standard Web browsers
• Provides a front-panel RF test point (at 20 dB below primary QAM output)
• Accepts variable and constant bitrate streams
• Provides Null packet insertion and deletion
• Provides PCR correction
• PSIP manipulation for SPTS
• PSIP pass thru for MPTS
To utilize the Pro:Idiom™ encryption feature, the input streams must meet the Pro:Idiom™
requirements. All QAM RF outputs will be encrypted regardless of the number of output modules
present or the number of QAM RF channels assigned on each module.
