54555701, Oct 3, 1995

Filed:

Oct 7, 1994

Appl. No.:

8/320107

Inventors:

Alex M. Cook - Lawrenceville GA
Luis A. Rovira - Atlanta GA
Curt M. Kuban - Snellville GA

Jeffrey C. Ting - Lawrenceville GA

International Classification:

H04Q 100

US Classification:

34082522

Abstract:

A remote control system including a hand held remote control unit with an alphanumeric information display, for controlling and communicating with a first controlled device, such as a digital music tuner connected to a community antenna television (CATV) cable, and for controlling a selected one of a plurality of second controlled devices, such as CATV set-top units, VCRs, or television sets. A first, high speed, error free display information communications protocol is utilized for transmitting program content or other information from a device, such as the CATV-connected music tuner, to the remote control unit for display. A second or control communications protocol is utilized by the remote control unit for controlling the first controlled device and a selected one of the second controlled devices. The CATV cable-connected music tuner utilizes the 44. 1 kHz Compact Disk (CD) clock signal embedded in digital music signals provided via the cable to derive clocking signals for implementing the display information communications protocol, resulting in an efficient, low cost electronic design.

International Classification:

H04N 7167

US Classification:

380 15

Abstract:

A television system having sync suppression scrambling and descrambling which includes in band and out of band signaling methods. The in band signaling method modulates the IF sound carrier of a premium video channel with timing and data pulses while the out of band signaling method modulates the previously modulated IF sound on a separate carrier onto a separate out of band data carrier. The in band signaling method uses a descrambler which tunes a channel before demodulating the timing and data pulses from the sound carrier while the out of band signaling method tunes a selected data carrier to demodulate the timing and data pulses. In both methods, the timing pulses are used to restore the levels of the synchronization pulses in the sync suppressed video signal, and thus descramble the signal, while the data pulses are used for addressable messaging to the descrambler including authorization. The out of band descrambler provides broadband sync restoration for a particular channel and thus does not need a broadband tuner for the video signal.

Appl. No.:

6/897878

Alex M. Cook - Lilburn GA

Assignee:

Scientific-Atlanta, Inc. - Atlanta GA

International Classification:

H04N 7167

US Classification:

380 20

Abstract:

Method and apparatus is disclosed for programming a CATV channel authorization unit. In a cable television (CATV) system, a CATV transmitter provides a plurality of CATV system channels to a channel authorization unit which in turn supplies only selected ones of the system channels to a user. The CATV authorization unit determines which selected channels the user will receive by receiving channel authorization data from a CATV system programmer. The channel authorization data is received via an infrared data communication link such that programming can be done without physical disassembly of the CATV channel authorization unit and without the system programmer being physically present within the users household. In a further embodiment, the CATV channel authorization unit is also responsive to a user transmitter for determining which of the selected channels the user is presently viewing.

International Classification:

H04W 48/20
H04W 36/32
H04W 36/30
H04W 24/02

Abstract:

Systems, methods, and devices are described for establishing communication with an access point. A wireless device may determine to switch to another access point radio based on a variety of factors. The wireless device may use a dynamic threshold to determine whether to switch to another access point radio. The dynamic threshold may be based on a current state of the wireless device. The wireless device may determine other access point radios to switch to directly or indirectly. An access point radio may broadcast information associated with the access point as well as information associated with other access point radios.
