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.

The appetite for online video is growing at an unprecedented pace. Consumers seem to devour content online as fast as it can be posted, and there doesn’t appear to be anything 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: over-the-top content delivery of catch-up or on demand services enable users to capture and view their desired programs at any time. This paper discusses key ingredients for deploying premium content over the top, and highlights the ground-breaking deployment by Portugal Telecom (PT) of 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.

In this paper we compare tTS over UDP.IP and TS over TRP/UDP/IP transport mechanisms with the so-called “native RTP” transport of MPEG-4 – the direct carriage of MPEG-4 encoded data in RTP packets. We highlight the benefits of the native RTP approach, focusing on IPTV applications such as broadcast and video on demand (VOD).

Scalable coding and multi-rate coding are the main solutions to address the problem of adaptive video streaming over heterogeneous networks. The variety of capabilities and qualities of different networks and decoders obliges content distributors to produce assets targeted for particular bandwidths and decoding platforms. This white paper describes how multi-rate coding is handled within Envivio products.
