Problems solved by technology

While advances in physical transmission networks (such as fiber optics and higher frequency ranges) have facilitated the transmission of such greater bandwidths, continuous advances in user control and transmission formats have allowed service providers to carefully and efficiently manage the available bandwidth to effectively serve large numbers of users.

Embodiment Construction

[0021] The following example depicts channel allocation for video services in a video services environment. Other environments are envisioned, as are additional services beyond the depicted example VOD, SDV, and 3D services. The illustrated example depicts channel allocation for optimizing service delivery to users by satisfying the largest number and / or most profitable service requests.

[0022] The video delivery server allocates channels to service subscriber requests. Subscriber requests, such as VOD or SDV requests, have bandwidth requirements to satisfy the request. Additionally, each service may have multiple media types for delivery, such as standard definition (SD) or high definition (HD). Thus, each subscriber request corresponds to a media type based on the bit rate and service requested by the subscriber. The required bandwidth is determined by the bit rate of the requested media type. For example, a VOD request could be for High Definition (HD) selection and r...

Abstract

A channel allocation mechanism for manages bandwidth using a channel profile to assure an available channel for supporting the highest expected bandwidth request by leaving a contiguous segment available to support such requests. Configurations discussed further below define a profile for expected media types, and associate each channel with a profile designating the media types assignable on that channel. Each media type includes a service and a bitrate, thus different formats of the same service (such as SD and HD) are distinguished. Each profile specifies a media type, and each channel is associated with one or more profiles. Further, a mapping of channels to associated profiles includes a reserve designation, indicating that other (unreserved) be fully assigned before assigning the reserved channels. The reserved channels provide a contiguous block of bandwidth, so that large bandwidth requests do not encounter assignment failure from a plurality of sparsely allocated channels.

Description

Background technique [0001] Traditional cable TV systems are simply the wire medium used to transmit radio frequency (RF) signals that were originally carried over the air. Coaxial cable (coax) carries the set of all available broadcast channels to each TV (subscriber). The set-top box in such a system simply provides a replacement tuner to receive the additional channels available via the coaxial cable. Each set-top box receives the same set of channels via the analog signal carried on the coaxial cable. [0002] In this legacy system, selective services (i.e., such as HBO "Movie" channels such as ) provide these premium services with physical filters typically located on cable drops to individual premises. With the advent of digital transmission media, the same coaxial cable also carried digital signals. Modern set-top boxes have evolved into individually addressable network devices, so premium channels become switchable from the central office or headend. Selective vi...
