Embodiment Construction

[0024] Except for the idea of ​​the present invention, elements shown in the drawings are well known and will not be described in detail. For example, familiarity with Discrete Multitone Transmission (DMT) (also referred to herein as Orthogonal Frequency Division Multiplexing (OFDM) or Coded Orthogonal Frequency Division Multiplexing (COFDM)) is assumed and is not discussed here except with the concepts of the present invention. describe. Again, familiarity with television broadcasting, receivers, and video encoding is assumed and not described here. For example, familiarity with current and proposed recommendations for TV standards such as NTSC (National Television Systems Committee), PAL (Phase Alternation Line), SECAM (Sequential Color and Memory), ATSC (Advanced Television System Committee) (ATSC), China Digital Television System (GB) 20600-2006 and DVB-H. Also, in addition to the concepts of the present invention, other transmission concepts are assumed, such as eight-l...

Abstract

A scheduler schedules multimedia content files for transmission over a broadcast network. Multimedia content files can be any sort of audio / video clips like, sports video, music video, news clip, movie sound track etc. In particular, the scheduler determines a transmission order for content files and generates an electronic service guide having a static part and a dynamic part such that content scheduled in the dynamic part may have a different transmission order in different versions of the electronic service guide. Schedule timing information and meta data information is transmitted over a broadcast network along with the clips so that receivers can do selective reception of their preferred clips, saving battery power and storage.

Description

technical field [0001] The present invention relates generally to communication systems, and more particularly to wireless systems, such as terrestrial broadcast, cellular, wireless fidelity (Wi-Fi), satellite, and the like. Background technique [0002] Today, mobile devices are everywhere, from MP3 players to personal digital assistants, to cellular phones, to mobile televisions (TVs). Unfortunately, mobile devices typically have limitations in computing resources and / or capabilities. In this regard, Internet Protocol (IP) data broadcasting over Digital Video Broadcasting-Handheld (DVB-H) is an end-to-end broadcasting system for delivering any type of files and services using IP-based mechanisms optimized for such devices . For example, see ETSI EN 302 304V1.1.1 (2004-11) "Digital Video Broadcasting (DVB); Transmission System for Handheld Terminals (DVB-H)"; ETSI EN 300468V 1.7.1 (2006-05) "Digital Video Broadcasting ( DVB); Specification for Service Information (SI) in...
