  • Page 79: Kencast File Delivery Over Satellite

    iPump 6420 User’s Manual sent in the first packet. If OK, the file is copied into the i6420 HDD filesystem at /u/user, creating new folders as necessary. This completes the immediate file delivery process. However, to keep the i6420 from wasting time accepting files not intended for it, it will receive a follow-on command from Compel ordering it to stop listening on the original UDP port.

  • Page 80: Http File Delivery Over Internet

    iPump 6420 User’s Manual 3.3.4. HTTP File Delivery over internet An alternate method of file delivery from Compel, that does not require a continuous satellite connection, is HTTP File Delivery over Internet. Here, the i6420 is commanded by Compel to request a file download from the Compel server using HTTP messages over IP. If a path to the server can be found, and the file is ready to send, then the i6420 may “pull”...

    iPump 6420 User’s Manual 3.3.6. “Asset Healing”, a content modeling & recovery utility After delivering files using AFD, WEGENER has a utility to allow the customers to model the files loaded to the field iPump6420s. This utility includes a function in the uplink control system and within the i6420.

  • Page 83: Insertion Of Audio From Stored Files

    iPump 6420 User’s Manual 3.4. Insertion of Audio from Stored Files This section discusses the reason Store/Forward implementers have purchased and deployed WEGENER iPump6420s. The essential function is to allow local file-based content to play in place of the live audio stream, synchronized to overlay specific time epochs we call “spot avails”.

  • Page 84: Playlists

    iPump 6420 User’s Manual 3.4.2. Playlists “Playlists” give the user the opportunity for insertion command indirection that makes localization convenient (see Figure 1-2), while allowing for more powerful file-based audio functions. By defining the same playlist name on many field iPump6420s, but each pointing to its own local files, the network, by requesting an audio insert with that playlist, can get a group of field i6420s to do a synchronized local insert.

  • Page 85: Timing Model

    iPump 6420 User’s Manual 3.4.3. Timing Model The timing model for insertion of file audio into the live audio stream is illustrated by the example shown in Figure 3-17. From the audio feed and companion closures emitted by the customer’s automation system looking forward, WEGENER’s Compel and iPump6420 both provide tools to align the local file insertion onto a network “avail”.

  • Page 87: Insertion Profiles

    iPump 6420 User’s Manual 3.4.4. Insertion Profiles Overview Insertion “profiles” are optional modifiers that are applied to an entire temporary insert, whether a discrete file or a playlist. This is invoked only by in-channel Compel commands. A field in the insertion command may specify a profile. Zero (‘0’) is the normal default in Compel commands and means “use no profile”.

  • Page 88: File Selection Keywords

    iPump 6420 User’s Manual 3.4.5. File Selection Keywords File selection keywords give the user the ability to play files in “random” order. These are typically used in temporary inserts ordered by Compel commands. However, they can be used as file specs in loop-forever playlist plays, a permanent Decoder (port) setting. The “keyword” signals to the playback process a method to select an audio file from a specified i6420 asset folder, whether top level, or deep in the directory tree.

  • Page 89: Figure 3-18: Example Of Using The Shuffle File Selection Keyword

    iPump 6420 User’s Manual Figure 3-18: Example of using the SHUFFLE file selection keyword Use of SHUFFLE keyword, a simple playlist example: Consider the following playlist definition: /assets/Song/Song_A.mp2 /assets/Spots/SHUFFLE /assets/Song/Song_B.mp2 /assets/Spots/SHUFFLE /assets/Song/Song_C.mp2 /assets/Spots/SHUFFLE Note that each time this playlist is invoked, it will play 3 files, each randomly selected from the / assets/Spots directory using the SHUFFLE keyword.

  • Page 90: Asset Aliases

    iPump 6420 User’s Manual 3.4.6. Asset Aliases Asset “aliases” are another simple method of indirection used to get localization. To use this, one must use asset-based files downloaded and managed from the uplink control system. In any file spec, whether used in a discrete file insert, or used in a line item of a playlist being inserted, the top level asset directory name must appear in the path.

  • Page 91: Am/Fm Tuner Setup

    iPump 6420 User’s Manual 3.5.1. AM/FM tuner setup Compel or the local user may setup the AM/FM tuners. The setup consists of programming the desired band and frequency. Once an external antenna connection has been provided, a user may use either the local user web or front-panel interface in order to check for received signal quality.

  • Page 92: File Return For Audit

    iPump 6420 User’s Manual 3.5.3. File Return for Audit As the captured OAR files accumulate on field i6420s, the Compel system may regularly request that they be returned so that they are available for auditing. This is done through the Return Path OAR file return report.
  • Page 93 iPump 6420 User’s Manual the currently-running application will checksum the received image, and if OK, process and load it to the non-volatile Flash storage, in the backup position. It will also mark the application image status flags. If the file was installed by a local user, the flags are always set to “OK” and that is the end of it.

  • Page 94: Non-Volatile Parameter Management

    iPump 6420 User’s Manual 3.6.2. Non-volatile Parameter Management All non-volatile unit settings (NV parameters) are retained in the internal flash memory storage, the same physical location as the Linux OS and the application images. At unit boot-up, these NV parameters are read into volatile memory for use. As these parameters changes, new values are written to the NV storage.

  • Page 95: Time Management

    iPump 6420 User’s Manual 3.6.4. Time Management Master Time Reference The iPump6420 makes use of a real-time clock (RTC) for many different functions, not just elapsed time. In most missions, the i6420 RTC must be synchronized to some other reference. In the majority of missions, this is the Compel clock.

  • Page 96: Hdd Failure

    iPump 6420 User’s Manual 3.6.5. HDD Failure The iPump6420 features an internal metal hard-drive (HDD) for storage of media files, playlists, databases, and logs. It also includes a small partition called the “Install partition”, but this is only useful to advanced users who may need, under WEGENER supervision, to rebuild or replace their Compact Flash memory cards.

  • Page 97: Microcasting (Aka "Automation Mode")

    iPump 6420 User’s Manual 3.7.1. Microcasting (aka “Automation Mode”) Microcasting is a new premium feature offered in the WEGENER iPump6420.* This allows the functions of the customer automation system to be embedded in the remote field i6420. Because of this, i6420s with no satellite access may provide operating radio stations with the same rich set of centrally-controlled services provided by their satellite brethren: live media (music/talk/news etc.) play, local spot insertion, cueing closures, RBDS messages, etc.
  • Page 98 iPump 6420 User’s Manual normally. What this means in practice is that operations will be moved up in time until the next “hard time marker”, at which time the unit should return to normal operations. To monitor a Microcasting session, the local web interface features an (Automation) sub-tab under Status for each Decoder.

    iPump 6420 User’s Manual 3.7.2. ShowShifting Overview ShowShifting is an exciting new premium feature in iPump6420 which allows satellite network operators to reduce the daily satellite bandwidth, and uplink storage, needed to distribute syndicated radio shows. In ShowShifting, a syndicated talk show (for example) can be air’d on the satellite a single time each day, but, at each of many field i6420s, that show episode can air on the respective local radio stations any number of times, with no start-time necessarily occurring at the original satellite air time.

In the Events file, all Compel commands which were associated with the audio stream while being recorded are themselves recorded. These are stored with precise timestamps indicating the exact time the command is to be executed, relative to the beginning of the episode.
