Converged Media

The process of convergence is particularly complicated as it involves bringing numerous divergent aspects, including technology, working processes, business approaches and even particular mind sets, together into a single cohesive whole. At ITAG, not only we tackled the problems of coming together of the network, devices, and Services to enable seamless interconnectivity with IP core network but also we are offering capability to provision business processes & workflows independent of access, devices and services.

  • Network Convergence

 

ITAG Video & Media Unified Network platform collectively provides an end-to-end information and entertainment ("infotainment") services platform that is extended from traditional fixed and broadband networks over broadband wireless networks to users of mobile devices in mobile environments. Our open platform architecture enables the convergence of network applications including:

• Data networking
• Security
• Network infrastructure
• Network applications
• Network management


ITAG delivers core network functions via a foundation of open-source software and general purpose Intel computing hardware. With this foundation, ITAG offers full flexibility, transparency, scalability, and expandability. ITAG product concept comprises layers of software components, called modules, operating potentially on multiple operating systems running on general purpose Intel/AMD-based hardware. Rather than relying on traditional proprietary hardware/software appliance structure, our platform allows the administrator to select the appropriate network and security applications that run on each device. ITAG enables

  • Device Convergence

 

What we are seeing here is a paradigm shift from an A/V content-centric home entertainment environment to a connectivity centric ecosystem of which A/V content is delivered to a multitude of devices. In our development and testing, the delivery mechanism, from user interface to back end transactional support, we design the ecosystem carefully in order to safeguard the consumer experience. With the convergence of media, we expect the emergence of appliances that will be able to display some sort of standardized media format. These devices will most likely vary in size, intended placement (living room, kitchen, bedroom), and functionality, but will have the common capability of being able to interpret the given converged media format. This means that the television in the living room will no longer be just a television, but it will be an "information" appliance. In addition to being able to display video streams, it will also be able to present other types of information-web pages, on-line stock quotes, interactive city maps, virtual lectures, etc.-that are encapsulated in the media stream, in other words a complete interactive system. As you know there a multitudes of OS such as Java, EBIF, iOS, Android, Blackberry, Symbian, MeeGo, Windows, Windows7Mobile, MacOS, and on and on are exist today. So an app not only has to work on all of them, but also work across all of them. This is an enormous challenge. At ITAG we support communication and media consumption to PC’s, STB’s, Tablets, mobile phones and we offer porting and testing of applications to multiple OS. Our offer includes but not limited to

  • Encoding: Input video is formatted to QVGA and compressed using H-264/AVC or H-264/AVS standard. We offer different video profile and data rates that can be applied using the encoder configuration. Output of encoding is a high-quality video at low bit rates suitable for mobile end-user terminals. Output from the encoding and encryption (optional), content could be directed to the IP-encapsulator or multiplex for packing and framing.
  • ESG/EPG: Formats channel and programs guide/schedules information as per ESG/EPG standard for broadcast transmission. ESG/EPG file packets are sent to the multiplexer.
  • Multiplexing: Multiplexer combines ESG, multiple audio/video channels and conditional access information into MPEG-2 transport stream package that is forwarded to distribution. Distribution network can be Satellite, WiMax, Canopy, microwave or optical fiber to transport multiplexed packed to the TV broadcast/streaming network.

Digital Media TX8-A
8-Channel MPEG-2/H.264 Transcoder for Mobile Applications

Reliable Carrier Grade Advanced TCA Solution

pic_mobile_applications_tx8-aAs the mobile market evolves broadcast operators need to deliver more content reliably and cost-effectively to their subscribers. The Digital Media TX8-A transcoder responds to this need providing the most powerful, efficient and cost-effective solution on the market today.
The Digital Media TX8-A is an 8-Channel MPEG-2/H.264(MPEG-4) Transcoder supporting a wide range of mobile applications allowing broadcasters to set up each of its 8 channels independently for optimum bandwidth utilization of their transport network.
The modular architecture based on a common ATCA blade simplifies system deployment, maintenance and scalability.

Scalability

The Media TX8-A scalable architecture can fit into any project: small or large. The broadcaster can even extend the number of video services at any time by simply adding more units without interrupting the existing services and seamlessly for the subscribers. The number of encoding cores on a single blade is configurable which adds additional flexibility during head-end deployments.

High Availability

The Media TX8-A is based on a telco-grade ATCA platform and the reliability of the whole encoding system is embedded into each transcoder. The Media TX8-A system of transcoders can be configured as a reliable and redundant system without the need of any external management component. In case of failure of an operational unit the backup unit(s) will take over and generate SNMP alarms and other notifications to an interested monitor.
The inherited reliability and high availability from the Advanced TCA architecture and shelf management makes the Digital Media TX8-A transcoder the best choice for complete head end solutions.

  • Service Convergence

 

Service Convergence is one way to popularize and monetize a specific service but in a Fixed Mobile convergence environment it is difficult to identify a unique blended service that it delivers on the converged media promise but also improves on services already available, in terms of efficient delivery and cost reduction. Here at ITAG we offer a strong, simple and clear message about the value added service of FMC convincing customers to use it. There are various attributes that have been bandied about as the core selling points of FMC: increased productivity in the enterprise sector; presence-based services integrated with other applications such as voice; VoIP and collaborative working models. However, these are all relatively vague and not easily marketable. Currently there is a lack of consistency and no discernable marketing strategy in place from any of the value chain players involved in converged media services.

As an example of our FMC-specific service is ITAG VoIP services. ITAG offers the use of VoIP in the wireless environment as a way to reduce calling costs when connecting with the core network through fixed wireless technologies. The primary usage models for ITAG VoIP are in the home, through applicable routers/access boxes, and in the outside environment, through Wi-Fi access in commercial hotspot zones. When no fixed wireless is available ITAG VoIP reverts to cellular carriage using cellular voice technologies as VoIP uses between 24Kbps to as much as 128Kbps of bandwidth compared with 3G, which delivers voice at 12Kbps.
