Embodiment Construction

[0017] 1 is a block diagram of a digital video receiving system for demodulating and decoding broadcast signals from multiple broadcast sources in accordance with the principles of the present invention. Although the disclosed system is described as being used for receiving a terrestrial broadcast video signal incorporating timing information and specific ancillary programs in an MPEG compatible format, it is illustrative only. The MPEG data format has been widely adopted and specified in the MPEG2 (Moving Picture Experts Group) picture coding standard, hereinafter referred to as the "MPEG standard", (ISO / IEC 13818-2, Issue 10, June 1994, and ISO / IEC 13818-1, Issue 20, January 1995). Specific program and timing information can be of various types. For example, it may conform to the Program Specific Information (PSI) requirements specified in section 2.4.4 of the MPEG Systems standard or may conform to the previously mentioned PSIP standard or other ATSC standards. In additio...

Abstract

A system processes packetized program information, from different broadcast sources, containing programs and program specific information including associated content rating data. A program specific parameter of a desired program is selected (310,320,330) based on its source from equivalent parameters from alternative broadcast sources. The desired program is processed (337) for display, recording or playback using the selected program specific parameter. The selected program specific parameter may comprise a content rating that is mapped (323) to a different program content rating system and used in multi-level validation (315,335) of authorization to access the desired program.

Description

technical field [0001] The present invention relates to the processing of programs received from multiple broadcast sources and associated content rating and system timing information for program play, recording and playback. Background technique [0002] In digital video and audio broadcast applications, packetized program information sent to a video decoder, such as a high-definition television (HDTV) receiver, contains broadcast channels from multiple broadcast sources, e.g., Fox 5 TM , Channel 13 TM . Packetized program information for a single broadcast station may contain data content for several program sub-channels occupying the frequency spectrum previously occupied by a single analog broadcast channel. Sub-channels may include, for example, digital services including the main programming channel, financial services providing stock quotes, sports news services, and shopping and interactive channels, all carried within the 6 MHz bandwidth previously allocated to a ...
