Voice over IP SUPPORT

  • What type of stream is generated by the Athensa AirBox Streaming Option?
Program Stream or Transport Stream, unicast or multicast, UDP or RTP.
  • What is the output compression of Athensa AirBox Streamer?
Depends on the mode used: The "IP Pump" mode outputs MPEG2 files at their original compression properties, i.e. bitrate, profile, level, etc. It can "pump" out SD or HD MPEG2 content. The "MPO Stream" mode outputs MPEG2, H.264/AVC
  • What is the Athensa AirBox "Streaming Option" doing?
It expands Athensa AirBox capabilities beyond standard video playout. With this option it is possible to output a live compressed stream either to a UDP socket or to a DVB device. This feature is part of Athensa AirBox Pro.
  • What DVB tables are generated by Athensa DVB Muxer?
The current PSI/SI generator integrated into the muxer generates the following tables: PAT = Program Association Table, PMT = Program Map Table, NIT = Network Information Table, SDT = Service Description Table, All other tables that might be required can be generated by an external PSI/SI generator.
  • If I receive multiple channels from a satellite can I select just one for live input in Athensa AirBox?
Yes, Athensa AirBox allows you to select a Program ID from the list of channels that are incoming (MPTS). This selection is based on PID numbers. Clip Trimmer can be used to preview and select separate PIDs.
  • If I have multiple Athensa AirBox streaming channels, how can I get them as a single IP output ?
You can use any DVB multiplexer to do that. Your most cost effective option is to use the Athensa DVB Muxer which would get the multiple separate AirBox UDP outputs and multiplex them as a single stream through a UDP socket. (ASI output is only aviable in old configuration with 32 bit Windows because of the video board. No one is using ASI anymore)
  • How can I generate DVB subtitles for my channels?
You can use our SubtitlePlus DVB Server which can generate dozens of subtitle streams for single or multiple output channels. The subtitle multiplexing with the video and audio streams can be done by Athensa DVB Muxer or by a third-party multiplexer. SubtitlePlus DVB Server listens to all Athensa AirBox servers and generates the subtitle streams based on the currently running programs and exact timecode. It works completely automatically.
  • How can I activate the live stream option?
It is important to know what type of streaming is needed - live input or live output streaming. The live input streaming is part of the Athensa AirBox PRO option (SDI input as well) The live output streaming is part of the Athensa AirBox Streaming option. If both are required, then both options have to be purchased.
  • Can I use live input streams in the playlist while streaming?
Yes, if you have the Athensa AirBox PRO option. You have to limit the duration of such continuous live streams up to 2 hours in order to avoid streaming buffer underflows or overflows due to input/output rate discrepancies. This limitation does not apply if both the stream input and output are synchronized to the same clock (e.g. genlocked).
  • Can I stream out multiple channels from the same Athensa AirBox DVB streaming server?
Yes, by using the "IP Pump" mode. Make sure the LAN bandwidth is sufficient for the intended number of streaming channels and their total bitrate. At least 30% overhead must be calculated to avoid theoretical and actual bandwidth discrepancies.
  • Can I stream MPEG4 out?
Yes, you can stream out H.264. H.264 is also known as AVC or MPEG4-part10.
  • Can I insert graphics while streaming?
Yes, as soon as the following conditions are met, you can use the "Stream" mode: you don`t need multi-channel streaming from the same chassis, the host server has sufficient CPU power, you don`t mind video recompression.
  • Can I change the bitrate of input streams in Athensa DVB Muxer?
Currently this is not possible. Bitrate changing currently can only be done by re-encoding by any of the Stream modes.
  • Can I avoid recompression by using the Streaming Option?
Yes, as soon as the following conditions are met, you can use the "IP Pump" mode: you don't need to insert graphics, your source files are the same bitrate as the target output bitrate, your source files are the same compression as the output compression (currently MPEG2 only)
  • What OS is supported from Athesa software?
Currently Athensa software support Microsoft Windows 7 Professional x64 with SP1.
  • Does your software run on Apple or Linux?
No, in an effort to keep our focus on software reliability we prefer to sacrifice flexibility and stick to the most popular operating system worldwide - Windows. If we had to support additional platforms we would face increased operational expenses (more development and testing personnel) and this would lead to an increased software price. We hope you can understand our position and use our products on Windows. If you have any concerns about Windows reliability, please let us know and we will be happy to explain.
  • Does Athensa AirBox supports subtitles? What subtitle formats are supported?
Yes, Athensa AirBox supports subtitles through integrated module called SubtitleBox (license option needed). Supported formats are Subtitle Plus (*.sub), Screen Subtitling/Win2020 (*.pac) and EBU t3264 (*.stl). We do recommend to use Athensa SubtitleBox with Subtitle Plus native format.
  • How can I generate DVB subtitles for my channels?
You can use our SubtitlePlus DVB Server which can generate dozens of subtitle streams for single or multiple output channels. The subtitle multiplexing with the video and audio streams can be done by Athensa DVB Muxer or by a third-party multiplexer. SubtitlePlus DVB Server listens to all Athensa AirBox servers and generates the subtitle streams based on the currently running programs and exact timecode. It works completely automatically.
  • Do you support CC (closed captioning)?
Closed captioning (CC) is the process of displaying text on a television, video screen or other visual display to provide additional or interpretive information to individuals who wish to access it. Athensa products support CC data for analog TV (EIA-608) with Decklink card and for digital TV (EIA-608 in EIA-708) with Deltacast card. CC data in MPEG2 TS and H.264 TS are supported.
  • What is the latest version of TitleBox?
You can check about the latest versions of all ATHENSA software from download section of our site https://athensa.tv/products/downloads/">https://athensa.tv/products/downloads/
  • When Titlebox 7 will be available for download?
TitleBox7 will be available for download at the end of June 2016.
  • Why is it not possible to edit content in Athensa TitleBox while it is in remote control mode?
Can you imagine the chaos that would be caused by local and remote control simultaneously? It won't be possible for Athensa AirBox to load a new template while the user is editing the old one, right? That's why once Athensa TitleBox begins listening to remote commands it doesn't allow the local user to interact with it. If your workflow requires template preparation or editing to be performed while Athensa TitleBox is slaved, we strongly suggest obtaining a preparation seat.
  • When I want to use RTF for a crawl the text retains the text formatting and does not crawl as a single line of text?
This is correct and logical. If you wish to run the text in a single line, it has to be a single line. Any new line in the RTF file is interpreted as a separate line of text to scroll.
  • What kind of scripting language does Athensa TitleBox support?
There is a native scripting language that allows Athensa AirBox or third-party applications to control Athensa TitleBox and its behavior. This language is described in the Athensa TitleBox API. Alternatively a simplified version is available through the Athensa AirBox graphic rules setup - it is described in the user's manual and lets the customer use a powerful titling automation engine based on clips metadata.
  • What is Athensa TitleBox Scripting Engine?
Athensa TitleBox Advanced Scripting Engine offers simple and powerful control of all objects and templates using Java, C# or Pascal to program the CG and graphics capabilities in either a scheduled or live environment.
  • What format do I need for high-quality animation in Ahensa TitleBox?
It is best to stick to the industry-standard 32-bit TGA sequence. You can import this sequence in Athensa TitleBox and it will create its own internal animation format. This format (unlike TGA sequence) is easily played directly from the hard-drive or from RAM (for small animations).
  • How can one insert a logo at the beginning and at the end of a crawl or roll that goes together with the text?
There are two approaches - insert a picture into the crawl/roll by using the Insert Picture button while editing the text object, or insert an tag. Please, refer to user's manual for detailed description.
  • Can Athensa TitleBox run on the same server as Athensa AirBox?
Yes, this is possible. Please note that the plug-in used in this case is different than the one used in stand-alone Athensa TitleBox installation. The installation process is explained in the user's manual and in case that you don’t find the information specific enough, please contact our support team.
  • Is AirBox7 available for download ?
AirBox7 will be available for download in June 2016.
  • What is the last AirBox version?
You can check about the latest versions of all ATHENSA software from download section of our site https://athensa.tv/products/downloads/
  • Do you generate an EPG (Electronic Program Guide)?
This is a job for the scheduling system as it deals with the actual program scheduling.
  • I have converted my DV files into upper field first, but they still plays as lower field first
Native field order for DV files is lower field first, and in order to re-encode them correctly to upper field first, “field blending” option must be used (in editing software)
  • Some of my files are having flickering/jerky motion, while other files plays OK
Customer is trying to play files with Upper Field First, Lower Field First and/or Progressive in same playlist. This is very poor practice since playing more that one type is not possible. Customer should choose one type of fields for all his files and reencode them to same field order.
  • What is MPO?
MPO stands for Multi Parallel Output. Athensa AirBox MPO enables the running of two or more outputs so that broadcasters can easily provide parallel outputs in any combination needed to deliver the content. For example, HD SDI and IP streaming at the same time.
  • Is it possible to change video and/or audio stream PIDs in Athensa AirBox?
Yes, but they are not user-definable. They can be changed by experienced technical personnel. The factory-default values are fixed at: Video = 256 (hex 100), MPEG audio = 512+ (hex 200+), AC3 audio = 768+ (hex 300+).The plus sign means that additional audio channel PID numbers increment, e.g. the second stream is 513, the third one is 514, etc. PID remapping can be easily done by DVB Muxer.
  • Is it possible to apply "video resize" to a single file in the playlist?
Yes. Each resizing is triggered by a scaling event in the playlist. Applying a resize to a single item can be easily done by inserting a scale event before this item.
  • Is it possible to trim clips with multiple video or audio channels?
Absolutely! If you use such a clip in Clip Trimmer, all available video and/or audio tracks are listed and you can choose which one to view/hear. Based on the video selection Athensa AirBox will play out the specified video track. The audio track selection is only for listening convenience while trimming - the audio tracks will be played out up to the extent of defined output audio channels (optional) and in the same order they are found in the original file, unless otherwise specified.
  • Can I resize the desktop video preview window?
Yes, if you make it an external window, you can set it any size. Look for the appropriate setting in Athensa AirBox Settings menu.
  • Is it possible to run more than one TV channel from the same server?
Yes, if you obtain additional Athensa AirBox licenses, you can playout as many channels as your hardware cards are. In most cases 4 or 5 channels is the maximum depending on the hardware cards and additional requirements (e.g. storage type, case size, etc.).
  • Is it possible to have mixed compression files in the same playlist for playout?
Yes, it is possible to playout files of various compression formats and containers, such as MPEG2, DV, IMX, MXF, H.264, WMV, etc.
  • Can Athensa AirBox read Cue tones for automated commercial insertion?
Yes, it can read many types of cue "tones": Analogue audio, SDI embedded audio, Live UDP audio stream, Live UDP stream with SCTE-35 markers. Based on pre-defined DTMF combinations Athensa AirBox can execute various commands, in a similar manner to GPI input.
  • Can Athensa AirBox playout content with slow motion
No, Athensa AirBox is not intended to be an instant replay server, and is not targeted for slow-motion VTR replacement.
  • Can you quickly explain what VoIP is?
VoIP stands for Voice over Internet Protocol. VoIP phone service, sometimes referred to as broadband phone service or digital phone service, is a phone service which operates using your high-speed Internet connection. There are mainly two kinds of VoIP services: phone-based and computer-based. These services allow you to make phone calls using either your regular phone or a computer headset with a microphone, respectively. As opposed to a traditional landline, when you use your phone or computer to call a number the call is sent over the Internet instead of over copper wires running out of your house.
  • How does one place or receive a VoIP phone call?
With a phone-based service you would use VoIP the same way you use a regular landline, by picking up the phone to answer it or dialing a number to place a call. With a computer-based service, you can call using a headset with a microphone plugged into your computer.
  • Can I call any phone or just VoIP phones?
Most providers allow you to call any phone number in the world, whether that number be a local, long-distance, mobile phone, or international number. However, some computer-based providers may limit you to other subscribers to that service (Commonly known as “User to User”). For your convenience, we list only those providers who allow their customers to call the regular phone network. Additionally, you may be able to speak with more than one person at a time using a feature typically titled either “Conference Calling” or “Three-way Calling.”
  • How is the voice clarity?
The quality of VoIP voice has dramatically improved over the past few years, reaching the quality level of a landline phone and sometimes even exceeding that level. However, voice clarity may differ from provider to provider and will also depend upon the speed and quality of your broadband connection. Before signing up, you may wish to consult other VoIP users by visiting either our forums or the user reviews for each specific provider.
  • Do I need a computer to call?
No, you do not need a computer for phone-based VoIP services. An adapter (often provided free of charge by the VoIP provider) connects the phone to a high-speed internet connection. A computer can be helpful to utilize and manage different features offered by the provider; however, it is not needed.
  • What differences are there between making a local call and a long-distance call?
In terms of technology or how you dial the number, there are no differences. Call charges, however, vary from plan to plan. Rates for long-distance calls are usually quite low. Furthermore, many VoIP providers offer unlimited long-distance in which case the calls are free.
  • Can you give me a technical overview of VoIP?
As the name implies, Voice over IP refers to calls that traverse networks using Internet Protocol (IP). The voice stream is broken down into packets, compressed, and sent toward its final destination by various routes (as opposed to establishing a single, 'permanent' connection for the duration of the call as with a traditional phone line), depending on the most efficient paths given network congestion, etc. At the other end, the packets are reassembled, decompressed, and converted back into a voice stream by various hardware and software elements, depending on the nature of the call and its final destination. For a more detailed technical overview of VoIP technology, please see our article: VoIP 101.
  • What can a VoIP phone do that a landline phone cannot?
A VoIP or broadband phone service can help you save up to 90% of your monthly phone bill. VoIP providers offer many features which are covered in the monthly fee, such as voicemail, caller ID, three-way calling, and call waiting. Many providers offer unlimited long-distance with their plans, which saves customers the trouble of having to purchase long-distance phone cards. Furthermore, most providers offer unlimited calling to other subscribers of the same service, allowing you to talk to those users for as long as you wish at no additional cost. VoIP service is best suited for you if you can relate with any of the following comments: - "I have a high speed internet connection and would like to lower my phone bills." - "I make expensive long-distance or international calls and would like to reduce those costs." - "I run a small business and phone bills make significant part of my overhead." - "I like the convenience of taking my number with me as I travel anywhere in the world." - "I'd like to utilize attractive features such as conference calling, choice of any area code, voice mail, caller ID, call waiting, etc." - "I'm frustrated with excessive taxes and long-distance company monopolies." - "I live outside the U.S. but I need a local NYC number for my business."
  • What are the disadvantages of VoIP phone service?
Some VoIP services do not work during power outages and the service provider may not offer backup power. Also, some providers do not give you the option to list your number amongst the white pages of your phonebook.
  • Does it come with 911?
Although most providers offer "Enhanced 911" (E911), it may be difficult for some VoIP services to seamlessly connect with the 911 dispatch center or identify the location of callers using VoIP. If you are troubled by this, you may wish to consider VoIP as an additional phone service instead of an alternative to a traditional phone line.
  • Can I keep my number?
Most providers allow number portability so you can use the same number which is given by your traditional phone provider.
  • Can I get a number of an area code other than mine?
Yes, your VoIP provider may permit you to select an area code different from the area in which you live. This means, if you live in Austin and get a New York number, you will NOT incur long-distance charges while calling a New York number regardless of geography. It also means that your "local" calls, in Austin , will be charged long distance and that your friends in Austin will incur long-distance charges calling your New York Number. Additionally, most providers offer virtual numbers (sometimes known as “extra numbers”). With this feature you may obtain a number from a different area code in addition to your current area code. This would enable you to have relatives living in another area code dial a local number to reach you, saving them the cost of long-distance charges.
  • Can I take my number with me when I travel?
Yes, most providers allow you to use your VoIP service wherever you travel as long as you have a high-speed Internet connection available and your phone adapter is with you. In this case, calling would work the same as if you were dialing from your home or business and you would not incur additional charges.
  • Can I try a service for a limited period?
Yes, many providers offer a no conditions 30-day money back guarantee so you can try a service without risk to see if it meets your needs.
  • What are other useful features?
VoIP services offer many features. We have identified about 70 different features. Note that by clicking on the name of each feature, the site will bring up a small window which provides the definition of that feature. To view which features are available under your desired plan, click on the link for your plans “Details” and then scroll down to “Advanced features.”
  • How secure are VoIP calls?
Although the media likes to play up future security threats in VoIP, so far, documented instances of VoIP security breaches have been few and far between. Also, the recently introduced encryption for VoIP subscriber units laid to rest many VoIP security questions. For more information see our articles: VoIP Security and FUD, and VoIP Encryption.
  • How do I get VoIP working for me?
There are mainly two kinds of VoIP service providers. Those that offer phone-based services such as Vonage and SunRocket, and those that offer computer-based services such as Skype. Each phone-based provider has different phone plans that are suited to meet different requirements. Since most computer-based services are limited to their own subscriber base (their basic service does not let you call any phone which doesn’t subscribe to the same service) we predominantly offer listing of phone-based VoIP plans. You can compare different plans available for your area and select the one that suits your needs best.
  • Do I need to be a computer expert?
For phone-based services you do not need to be computer savvy. Even computer-based services are not too difficult to set-up.
  • What kind of equipment do I need?
A broadband (high-speed Internet) connection is required. This can be a cable modem or a high-speed service such as DSL or a Local Area Network (LAN). To place a call into the regular (PSTN) phone network you will need a VoIP service provider. The VoIP service provider will send you an adapter that you can plug into your Internet connection and then you can plug your regular analog phone into the adaptor. Alternatively, you can hook up a relatively inexpensive microphone to your computer and send your voice through your computer and its high-speed Internet connection.
  • Will I have to buy the equipment myself?
The equipment is often provided free of charge by the VoIP service provider. Such equipment is usually to be returned in the event you cancel the plan. Some providers also give you the option of keeping the equipment by letting you purchase it during sign-up.
  • How fast does my internet connection need to be?
The average DSL or cable connection is usually sufficient. A few providers offer service to dial-up internet customers. VoIP service with dial-up is not advised due to common complaints of poor voice quality and reliability. We recommend you check your connection speed here to determine the quality of your connection. http://www.VoipReview/voipspeedtester.aspx
  • Can I use my computer during a call and does it have to be turned on all day?
You can use the computer; depending on your service provider, a router may be required. Your computer need not be turned on if you are making calls with a phone and adapter or a special VoIP phone, but your broadband Internet connection must to be active. As an added note, you can use your computer and surf the internet while talking on the phone without greatly affecting voice quality.
  • How do I get started?
You first need to determine which plans are available in your area and then select one you like best. You can start a search for plans from our homepage.
  • Where can I find more info?
If you have questions about using this site, please view our Site FAQ (which immediately follows this article). In addition to our many articles on VoIP, you may view user reviews of different providers to learn about the experiences of those users or you can pose a question in one of our forums.
