Embodiment Construction

[0021] BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a block diagram of a digital video receiving system for demodulating and decoding broadcast signals in accordance with the principles of the present invention. Although the disclosed system is described in terms of a system for receiving a video signal containing program specific information including program guide data in an MPEG compatible format, it is exemplary only. Program specific information can be in a variety of forms. For example, it may comply with the program-specific information (PSI-Program Specific Information) requirements specified in Section 2.4.4 of the MPEG system standard, or it may comply with the requirements of the American Advanced Television Systems Committee (ATSC-Advanced Television Systems The high-definition television (HDTV) signal standard "HDTV Transmission Digital Television Standard (DigitalTelevision Standard for HDTV Tvansmission)" formulated by the Committee or other ATSC standards.

Abstract

Packetized program information used in video processing and storage medium formats includes multiple text strings. A decoder decodes packetized program information containing multiple text strings associated with a program. The decoder determines from a first indicator in the packetized program information a type of coding and compression employed in encoding a first text string. The decoder decodes the first text string with a decoding function selected in accordance with the determined type of coding and assembles decoded text string elements to form an output text string.

Description

technical field [0001] The present invention relates to the generation of program guide, system information and program specific information for MPEG compatible processing. Background technique [0002] In video broadcast and processing applications, digital video data is typically encoded to conform to the requirements of a well-known standard. One such widely adopted standard is the MPEG 2 (Moving Picture Expert Group) image coding standard, hereinafter referred to as the "MPEG standard". The MPEG standard includes a system coding part (ISO / IEC 13818-1, June 10, 1994) and a video coding part (ISO / IEC 13818-2, January 20, 1995). Data encoded to the MPEG standard is in the form of a packetized data stream that typically includes data content for a number of program channels (eg, content corresponding to cable TV channels 1-125). Additionally, several digital services and channels can occupy spectrum previously occupied by a single analogue channel. The 6MHz bandwidth prev...
