Building on its expertise in low bit rate mobile broadcast and IP-based video networks, Envivio has expanded the capability of its statistical rate control (SRC) within its encoding platform to address the requirements to broadcast high quality HD and SD services using MPEG-2 and MPEG-4 encoding in mobile, terrestrial, satellite and cable distribution networks. The new SRC provides the highest quality video services in a bandwidth-constrained environment for a wide range of applications and distribution formats. This paper describes the open head-end architecture as well as the quality improvements and bandwidth efficiencies gained by using Envivio Statistical Rate Control.

To address the challenges and opportunites created by the changing dynamic of TV consumtion, and to make the most of new distribution opportunities, Envivio has developed Genesis™—a standards-based, universal, mezzanine output format that transforms TV headends into efficient multi-screen delivery engines. This paper explores the TV Everywhere dynamic and how Genesis slashes backbone bandwidth requirements by simultaneously supporting the multiple bit rates and resolutions needed to service the range of consumer devices and networks.

The personal video recorder has had a tremendous impact on the way people consume television content. Increasingly it is not only freedom from time, but freedom of place that is driving consumer habits. The ready availability of high-speed broadband networks and the increasing appeal of video-enabled mobile devices are diverting consumer eyes away from the fixture of the traditional TV and drawing them to alternative devices such as PCs and smartphones. This paper explores the challenges and opportunities that face operators as consumption of TV services evolves.

The technology and business of television have changed dramatically in recent years. Consumer viewing habits have shifted, fueled by new choices made possible by the Internet, the proliferation of broadband to a range of wired and wireless devices, and a revolution in the variety and quantity of content available. How content is acquired by consumers is evolving rapidly. While most people still turn to the television to watch video, the availability of mobile broadband is making it possible to watch that same content in many different places and at any time that is convenient.

The appetite for online video is growing at an unprecedented pace. It started with YouTube, and has been fueled by new service launches like Hulu and Vevo. In the U.S., Netflix is transforming itself from a DVD rental company to an online streaming service. Consumers seem to devour content online as fast as it can be posted, and there doesn’t appear to be anything that will slow the pace. With huge audiences finally embracing new television distribution models, leading technology companies have begun developing new services that take advantage of the new devices: Internet TV and over‐the‐top (OTT) content delivery of catch‐up or on‐demand services enable users to capture and view their desired programs at any time. This paper, co-authored with Verimatrix, explores the requirements and provides a solution overview for a multi-scrfeen environment.

Today people are watching more television programming, from more sources, on an increasing variety of screens than ever before. And with new mobile devices coming to market at faster and faster paces, the demand will continue to grow. There is a huge opportunity to capture a rising percentage of a viewer’s time, if one overcomes the challenge of delivering a great viewing experience with exceptional quality to multiple devices, whatever the network conditions. This paper explores the importance of video resolution and optimization for each device and screen, and makes recommendations for producing the best quality video in every situation.

Portugal Telecom (PT) is the largest telecommunications and broadband service provider in Portugal. In April 2008, PT launched MEO, an IPTV and satellite TV service composed of 120 channels and +2,000 VOD content. With advanced functionalities such as pause TV for live channels, PVR and interactive service guide, MEO reached over 500,000 subscribers in less than 17 months. This paper discusses key ingredients for deploying premium content over the top, and highlights the ground-breaking MEO@PC, a joint Envivio/Microsoft Silverlight-enabled service .

Mobile TV has become a key, if not the key, application that mobile operators need to deploy to attract new subscribers, or simply retain their existing base. Even before the business models and killer applications for mobile video have been fully explored, mobile operators and broadcasters already face a wide variety of mobile video distribution standards, devices, and applications that deeply impact the way in which those services are deployed. This presentation will focus on the knowledge gained from early deployments of MPEG-4 encoders for Mobile TV. Featured highlights include case studies on the Orange (France) 3GPP deployment, with an overview of its technical challenges as well as current requirements for successful Mobile TV deployments.

For many years, the broadcast industry has used expensive and proprietary hardward to provide statistical multiplexing features in MPEG-2 transport stream-based networks. With the advent of IP-based networks,t he notion of multiplexing and de-multiplexing sources that are bundled together is becoming less important, while the requirement to fit bultiple channels in a bandwidth-constrained network remains essential. This paper explore the Envivio approach to these challenges.
