MIP-921^e

EAS Compliance Solutions

The MIP-921 (Multiple Input Processor) has been specifically designed by HollyAnne Corporation to meet the Federal Communications Commission’s mandate for cable television system compliance with the new Emergency Alert System rules. HollyAnne Corporation’s 15 plus years of experience in the emergency warning industry has made it an acknowledged leader in the cable television warning field. The MIP-921’s designer collaborated with the National Weather Service in the development of the Specific Area Message Encoding system. The SAME system was the precursor of and is completely compatible with the new digital EAS protocol. HollyAnne Corporation and its distributors offer the knowledge and experience to ensure the most appropriate solution to your system’s needs.

The MIP-921 receives both national and local messaging via two internal AM, FM and/or weather band radios. It also can receive emergency messages via its telephone modem. The MIP-921 incorporates the required EAS encoder and decoder. It responds to the National Weather Service’s digital SAME protocol as well as the mandated EAS digital format.

Multiple inputs from the two internal radios, a telephone interface, and inputs for 2 external radios exceed the FCC’s requirements for a minimum of two alerting sources, allowing flexibility to handle additional alerting sources including local government agencies which may be dictated by franchise requirements.

The MIP-921 is capable of completely automatic operation. Events selected by system management in advance activate the MIP-921. These events include national warnings, weekly and monthly tests and those emergency events deemed important by system management. Logging is done by the on-board printer. The audio portion of the message is stored and played back by the internal digital voice storage module. A separate “Tune To” voice storage module is standard.

The MIP-921 immediately and automatically passes information to a character generator (to override video signals) and to each modulator’s I.F. interface (or combining network) to override audio signals on all channels carried by the cable system. The system is also capable of manual operation. All functions are password protected.

The MIP-921 has been designed to accommodate in home alerting devices to deliver necessary information that may be required by the FCC, via a 52 MHz carrier. These in-home devices feature contact closures to activate tactile signaling devices such as strobes and pillow shakers.

Audio/Video Override On All Channels
A cost-effective solution for cable systems with I.F. switching capabilities

Provides audio and video information on all channels on the cable system. Text appears full screen. To satisfy requirements of the Americans with Disabilities Act, deaf subscribers are alerted by the video information on every channel; the blind are alerted by audio on every channel.

The EAS encoder/decoder (MIP-921) drives a character generator that feeds an I.F. controller. In turn, the I.F. controller feeds an I.F. signal carrying the audio and video messages into each modulator and processor in the headend. All events are logged on either the on-board printer (optional) or a customer-supplied external printer.

When an emergency or test message is received, the I.F. controller’s modulator output delivers the override information to the input of each processor and modulator in the headend. The I.F. controller activates the I.F. switching modules on each modulator/processor, overriding the regular programming. Once the End of Message code is received, normal programming can be resumed.

Operators of cable systems with I.F. switching already installed for every channel may find this option cost effective. While direct input into each channel’s I.F. port can result in labor intensive installation, larger cable systems serving a considerable number of deaf subscribers may realize cost savings over Configuration Option 2.

Provides audio override with video interrupt across all channels, with one channel designated for both audio and video information. Video interrupt displaces the picture with a gray raster screen for short periods. To satisfy the ADA, an equivalent alerting function must be provided to deaf and hard-of-hearing subscribers throughout the system. This requirement is satisfied through separate in-home devices, such as a SAM™ A Receiver, that also activates deaf subscribers’ strobe lights, bed-shakers, etc. The SAM™ receiver also carries audio alerts and voice warnings.

This configuration does not require separate inputs to each processor and modulator on the system. The EAS encoder/decoder (MIP-921) drives a character generator, the output of which feeds a modulator for the designated audio/video channel. Combined with an audio input from the EAS decoder, the modulator’s output feeds a comb generator that also takes inputs from the combining network, and control and audio inputs from the EAS decoder. All events are logged on either the on-board printer (optional) or a customer-supplied external printer.

When an emergency or test message is received, the MIP-921 activates the character generator, which passes the emergency text messages to the modulator for the single A/V information channel. The MIP 921’s output and the audio information for all other channels are fed to the comb generator, which feeds the distribution system, overriding the regular programming with video interrupt. A separate 52 MHz carrier from the EAS decoder delivers the same emergency messaging to activate in-home devices for the deaf. Once the End of Message code is received, normal programming is resumed.

Less labor intensive than Configuration Option 1, the R.F. solution will appeal to cable operators whose headends are not already I.F. equipped. This option also offers efficiency for those who estimate a relatively small number of deaf subscribers on their systems.

Provides audio and video information full screen on all channels on the cable system (up to 117 channels). To satisfy requirements of the Americans with Disabilities Act, deaf subscribers are alerted by the video information on all channels; the blind are alerted by audio on all channels.

This configuration does not require separate inputs to each processor and modulator on the system. The EAS Encoder/Decoder (MIP-921), drives a character generator/switcher, the output of which feeds an audio/video comb generator. The comb generator is fed with the combined RF outputs of the cable headend, allowing the “trunk out” of the headend to be switched during the activation, feeding all channels with emergency audio and video. All events are logged on either the on-board printer (optional) or a customer supplied external printer.

When an emergency or test message is received, the MIP-921 activates the character generator which passes the emergency message video to the comb generator where it, along with the emergency audio from the MIP-921, is inserted on all channels (up to 70). There it replaces normal programming until the digital end of message signal is received by the MIP-921. If desired, a single channel may be selected as a details channel. If this option is selected, the details channel may be left in place for a variable length of time, such as for the length of the emergency (directed by the MIP-921). The details channel option requires a band pass filter as shown in option 2.

Less labor intensive than configurations 1 and 4. The audio/video solution will appeal to cable operators whose headends are not already IF equipped, but who wish to provide both audio and video warning on all channels. This option offers efficiency for operators of medium to large systems who estimate a relatively large number of deaf subscribers.

Provide audio and video emergency information on all channels on the cable system. The video information appears as a crawl at a location on the screen that does not interfere with closed caption messaging. To satisfy requirements of the Americans with Disabilities Act, deaf subscribers are alerted by the video crawl on each channel. Blind customers are alerted by the audio message on every channel.

The EAS Encoder/Decoder (MIP-921) drives a character generator that feeds a base band processor. This processor synchronizes the program video with the emergency video from the character generator. The MIP-921 also transmits emergency audio to the base band processor. Each cable channel requires an audio/video generator lock module. All events are logged on the on-board printer (optional), or on a customer-supplied external printer.

When an emergency or test message is received, the MIP-921 sends data to the character generator and audio to the base band controller. The character generator provides the emergency video to the base band controller. The controller activates the audio/video generator lock modules to synchronize the emergency video on each channel’s regular program video and replaces the regular program audio with emergency audio. Upon receipt of the End of Message signal, normal programming is resumed.

Operators of cable systems that choose this option will be able to provide emergency announcements and test messages in a less intrusive manner than other options that produce a full screen interruption. While direct interruption of each channel’s base band audio and video results in a relatively labor intensive installation, larger cable systems that serve a large number of deaf customers may find this option more desirable than ones that require the installation of in-home receiving units for deaf customers. While this “crawl” option is more costly than those that depend on full screen interruption, the less intrusive nature of a crawl may pay for itself in improved customer relations.

A less intrusive solution for cable systems that wish to crawl emergency messages over program video

When an emergency or test message is received, the MIP-921 sends data to the character generator and audio to the base band controller. The character generator provides the emergency video to the base band controller. The controller activates the audio/video generator lock modules to synchronize the emergency video on each channel’s regular program video and replaces the regular program audio with emergency audio. Upon receipt of the end of message signal, normal programming is resumed.
