US Patent:

6594361, Jul 15, 2003

Filed:

Jan 30, 1997

Appl. No.:

08/792816

Inventors:

John William Chaney - Noblesville IN
Michael S. Deiss - Zionsville IN
Billy W. Beyers - Greenfield IN

Assignee:

Thomson Licensing S.A. - Boulogne-Cedex

International Classification:

H04N 7167

US Classification:

380221

Abstract:

An access control system for signal processing applications includes an integrated circuit (IC) card, or âsmartâ card, that provides both security control and data descrambling functions. A security control processor in the smart card IC performs functions such as entitlement management and key generation. The smart card IC also includes a descrambler for processing data, such as video data, at high data rates. Mechanical characteristics of the smart card satisfy the ISO standard 7816-1. In addition, the interface to the smart card is via eight-terminals arranged on the surface of the card in accordance with ISO standard 7816-2. The eight terminal interface provides both high speed data I/O (input and output) required for data descrambling and ISO standard low speed serial data I/O.

International Classification:

H04N 7167

US Classification:

725 31, 725151

Abstract:

Apparatus in a receiver, for processing transmitted entitlement control information, includes a packet transport processor for selecting signal packets having payloads containing a conditional access payload header and a remaining payload of entitlement data. Respective payload headers include groups of bytes which are coded in a manner to allow or disallow the respective receiver from processing the entitlement data. A conditional access filter preprogrammed with a subscriber specific conditional access codeword examines respective byte groupings of the conditional access header for a match with the subscriber specific conditional access codeword. Only if a match occurs is the processor permitted to process the entitlement data. The entitlement data is thereafter utilized to generate decryption keys for descrambling portions of the transmitted signal.

US Classification:

725 25, 725 31, 725 27, 725 28, 725131, 725139

Abstract:

A method and an apparatus for processing a packetized transport stream that determines whether a sequence of transport packets are received in a proper sequence and whether an error is present in a particular transport packet. The method includes the steps of determining a packet identifier for identifying transport packets associated with a selected program and parsing a packetized transport stream to identify and capture the desired sequence of transport packets in response to the packet identifier. The method further includes the steps of detecting a counter portion, determining whether a desired sequence of transport packets has been received in response to the counter portion, detecting a one bit toggle portion, and determining whether an error exits in the associated transport packet in response to the one bit toggle portion. An apparatus for implementing the method is also disclosed.

International Classification:

H04L012/56

US Classification:

370389000

Abstract:

A method and apparatus for processing a packetized data stream comprising audio and video components and program guide information. The program guide information has a predetermined service identifier and includes service identifier information associated with audio and video program components. The program guide information is used to identify service identifiers associated with a selected program. The identified service identifiers are used to acquire data packets associated with the selected program. The acquired data packets are processed in accordance with a video signal standard to generate output signals representative of the selected program.

International Classification:

H04N 974
H04N 550

US Classification:

3581911

Abstract:

It is herein recognized that it is desirable that a television receiver provide preprogrammed labels for many widely-used television networks. The user has only to select the proper channel and then select a corresponding preprogrammed label from a list in order to associate the channel and label. In one embodiment the preprogrammed label is a graphically-formed logo or service mark of the television network.

US Classification:

358182

Abstract:

It is desirable that a television receiver provide a prominent visual indication that it is about to automatically turn off. On-screen display (OSD) circuitry automatically reduces the viewable picture area to a small area before turning off the receiver. Reduction of the viewable area may be performed by displaying and gradually enlarging at least one graphically-generated margin of the OSD display.
