Problems solved by technology

[0017] The above discussion shows that prior solutions cannot provide both VOD and digital broadcasting in a single system
In contrast, prior solutions are limited by several factors
A major limiting factor is that prior art streams use the MPEG-2 Transport Stream

Abstract

The present invention teaches methods and systems for providing full digital services such as VOD, digital broadcast, as well as a universal set-top-box (STB) capable of handling this variety of digital services. A plurality of hardware architectures and complimentary data transmission methods identifying the distinct services through an electronic program guide enable such transmission. The universal STB of the present invention is capable of distinguishing the different services based upon information received in the electronic program guide, and is designed with unique hardware architecture including a large buffer. The present invention further provides viewing options such as multiple broadcasts and virtual VCR time-shifting features including pause, recording, and freeze-framing a broadcast without suffering the volatility and poor quality of an Internet streaming broadcast. Still further, this variety of digital services is provided via a uni-directional communication link.

Description

technical field [0001] The present invention relates to video-on-demand and digital broadcasting technology. In particular, the present invention teaches methods and systems for providing fully digital services such as VOD, digital broadcasting, time shifting from any broadcast medium, and set top boxes (STBs) capable of handling all of these kinds of data services. Background technique [0002] A wide variety of mechanisms are available for encoding and transmitting digital data. For example, the International Organization for Standardization (hereinafter referred to as "ISO / IEC") has introduced a standard (MPEG-2) for encoding moving pictures and related audio. Due to its ubiquity and its relation to the present invention, some preliminary description of MPEG-2 is necessary. [0003] The ISO / IEC MPEG-2 standard is stated in 4 documents. The document ISO / IEC 13818-1 (Systems) specifies the system encoding for this specification. This document defines a multiplexing stru...
