Two way Hybrid Fiber/Coax (HFC) networks are being rapidly deployed by major cable TV companies. This paper proposes an open platform consisting of a home set top box plus supporting network elements that would allow cable operators to offer advanced services that other delivery media would have difficulty in matching. The platform would support both analog and digital video broadcast delivery as well as provide two way Internet Protocol (IP) connectivity to the set top box. The set top box would combine the capabilities of a digital broadcast set top box and a network computer-like platform. It is recommended that such a platform supports open API's such as HTML and Java. With such tools, integrated video and data applications can be developed. The platform would be based on open standards such as the Society of Cable Telecommunications Engineers (SCTE) Digital Video Subcommittee standards for digital broadcast and interactive standards such as MPEG Part 6 (DSM-CC) and DAVIC.

Services targeted to the home environment must deal with software and hardware heterogeneity of client and server machines. Distributed object based middleware is attractive for building distributed services in such heterogeneous environments for a number of reasons. In particular, distributed objects can hide the complexities that arise from distribution and heterogeneity in the underlying system. To deal with the scale of home based applications and to reduce the effects of high latencies in such environments, we have been exploring efficient implementations of distributed object systems that exploit caching and replication of service state. In this paper, we explore issues related to object state caching and communication for distributed object systems.

The residential gateway (RG) is a critical element in offering residential broadband services. An RG provides the interface between customer premise equipment (CPE) and the network provider's residential access network. This paper examines the impact of two broadband services on RG functionality: high speed data service and video service. Sample protocol architectures capable of supporting these services are analyzed to assess the types of RG functionality required. Based on this work, it is concluded that RG functionality should be viewed as a strategic issue for companies offering broadband services.

Considers the problems of Internet congestion and delays from an economic viewpoint and proposes a solution that properly aligns the economic incentives for both users and providers. As currently structured, economic incentives do not promote efficient usage. Furthermore, the current structure does not provide any incentive for service providers to increase capacity, and it does not allow them to provide the better-quality service that many users would be willing to pay for. We develop a properly incentivized economic scheme and an implementation strategy, taking into account the operational details of the medium and the realities of the market. The performance of the proposed plan is analyzed according to queuing theory, producing promising results.

This paper elaborates on the role and evolution of screen phones for the deployment of interactive services on the Public Switched Telephone Network (PSTN). Today, and for the next few years, Advanced Screen Telephony remains a means to enable the Public Telephone Network Operators to implement new services and offer them directly to the customer. With a modest investment in new equipment, they can create a highly loyal user base through the deployment of a variety of new services tailored to the needs of large communities of individual users.

In this paper, the situation of an emerging home network environment is examined. There are four driving needs for a home network. They are home automation, home computer, digital audio and video distribution, and digital access network. In the past, the home network is driven by home automation and analog audio and video distribution systems. Most recently, the effort on the development of a digital home network has been driven by emerging digital access and digital consumer electronics technologies. The system requirements are analyzed for different home network applications. The possibility of using IEEE 1394 protocol for a digital home network is explored.

Technical models from software development methods and metacomputer architectures can be adapted to meet many anticipated requirements.

The home PC, and the home computing environment in general, has undergone a significant evolution. We trace this evolution, and argue that the time is ripe for the development of an integrated networking infrastructure within the home, with the home PC as the focal point. Consumers to whom we have talked have definite ideas on what they would like to do with this infrastructure, and we discuss both their desires and their concerns. We present a high-level architecture for home networking, and describe IBM products and prototypes that represent the early stages of implementing this architecture.

In this paper we outline several high-performance prefetching protocols for the transport of VBR-encoded video on demand. For the same image quality and cost, our protocols allow a VoD service provider to provide significantly more video connections than what is possible with CBR-encoded videos. The protocols therefore allow VoD service providers to earn significantly more revenue without increasing cost. The protocols require each client to have about 10 Mbytes of memory dedicated to the VoD application. Our protocols are particularly well-suited for the provision of VoD from a cable headend or from an ADSL switch over a community network to household PCs or to Web-TVs. The protocols are designed for high-performance video-on-demand: They give immediate commencement of playback upon user request, they allow for instantaneous user interactivity, and they promise consistently high image quality. We present two protocols. The first protocol is appropriate for when all of the videos emanate from a single server. The second is appropriate for when the videos emanate from multiple servers.

Commercial deployments of digital TV provide a digital video broadcast (DVB) infrastructure. DVB is a large digital broadband network with data delivery capability and with digital terminals (set-top boxes) at the user premises. As such, it provides a powerful platform for delivery of additional information and data services that can not only enrich but fundamentally transform the television viewing experience. This paper provides an overview of an architecture for interactive service delivery to home via the DVB infrastructure in systems with and without the return channel. The presented approach relies on a novel broadcast model of computing which is ideally suited to the DVB infrastructure. This model works even with low-cost user terminals, such as the basic digital TV set-top boxes with limited computational and graphics capability and no local disk storage.
