A communication system includes a content repository storing a content file and a video transport processing system receiving the content file and dividing the content file into a plurality of content file portions, forming a leading data portion, determining a cyclic redundancy check value, forming a trailing data portion with the cyclic redundancy check value therein, forming a content data stream from the leading data portion, the plurality of content file portions and trailing data portion. The system also includes a system communicating the content data stream to a user device.

Method and system for forming a formatted content stream and using a cyclic redundancy check

A system for delivering satellite signals to a plurality of display platforms. A system in accordance with one or more embodiments of the present invention comprises a first transmission system for delivering the satellite signals to a first display platform via at least one satellite, and a second transmission system, coupled to the first transmission system, for delivering at least a portion of the satellite signals to at least one second display platform, the first transmission system and the second transmission system transmitting in a substantially simultaneous manner, wherein the second transmission system transmits a data stream formatted for compatibility with the at least one second display platform.

Mobile streaming processing system for video and audio content

A communication system includes a content repositorystoring a content file and a video transport processing systemin communication with the content repository. The video transport processing systemreceives a plurality of conditional access information, stores a relative time of arrival of each of the plurality of conditional access information and encrypts the content file using the plurality of conditional access information and the relative time of arrival to form an encrypted content file.

Method and system for forming a content stream with conditional access information and a content file

A system and apparatus for generating an output signal includes a receiving systemgenerating a plurality of signals having a first format, an encoderencodes the plurality of signals into a plurality of transport streams and a multiplexer. A local area networkroutes the plurality of transport streams to the multiplexer. The multiplexercombines the transport streams to form a combined signal and inserts a digital video effect into the combined signal. A modulatormodulates the combined signal to form a modulated signal. A systemforms the output signal from the modulated signal.

Method and system for inserting digital video effects into a video stream at a multiplexing device after routing

A communication systemincludes a content management systemdetermining a programming schedule and a video transport processing systemreceiving a content file in forming a transport stream from the content file having a plurality of packets, each having a header with a first packet identifier in the header and a data portion. The communication systemfurther includes a content repositorystoring the content in a satellite transport processing systemchanging the first packet identifier to a second packet identifier in response to the programming schedule and communicating the transport stream to a user device.

Method and system for communicating content having modified packet headers through a satellite

A system and method of generating an output signal includes a receiving system generating a plurality of signals having a first format, an encoderencoding the plurality of signals into a plurality of transport streams and a multiplexer. The system also includes a local area networkrouting the plurality of transport streams to the multiplexerto form a combined signal, a modulatormodulating the combined signal to form a modulated signal and a systemforming the output signal from the modulated signal. In one aspect, the output signals may be satellite uplink signals.

Method and system for generating uplink signals from a ground segment

A broadcast system includes a program guide system, a traffic and scheduling system having a traffic and scheduling database having a program schedule therein. The system also includes a broadcast operation channel management system initiating a channel mapping change or channel definition change using the program schedule and communicating a change notification to a traffic scheduling system from the broadcast operation channel management system, extracting channel data from the channel mapping or channel definition change. The broadcast operation channel management system communicates the channel data to a program guide system.

Method and system for communicating changes in a broadcast system to other broadcast components

A system and apparatus for generating an output signal includes a receiving systemgenerating a plurality of signals having a first format and communicating the plurality of signals simultaneously through a primary path and a secondary path. A digital video effects moduleinserting a digital video effect into at least a first signal of the plurality of signals in a primary path. An encoderencoding the plurality of signals into a plurality of transport streams and a multiplexer. A local area networkroutes the plurality of transport streams to the multiplexer to form a combined signal. A modulatormodulates the combined signal to form a modulated signal and a systemforms the output signal from the modulated signal.

Method and system for inserting digital video effects into a video stream in redundant paths before routing

A system and method for distributing requested content includes a content management systemand a devicesuch as a set top box that selects a selection corresponding to content in the content management systemand transmits a first material identification to the content management system. The content management systemtransmits the content to the device with a second material identification associated therewith. The devicereceives the content and the second material identification and compares the first material identification to the second material identification. When the second material identification corresponds to the content, the device continues downloading the content. When the second material identification does not correspond to the content, downloading of the file is discontinued. A content prefix may also be used alone or in combination with the material identification. The content is prevented from being transmitted if the content prefix does not correspond to the content type.

Method and apparatus of verifying that requested content matches content to be downloaded

Methods of testing receiver video fidelity are disclosed. One example method includes producing a video test signal; coupling the video test signal into an input of the receiver, wherein the video test signal is configured to cause a decoder to output a step function signal upon processing the video test signal; coupling the step function signal to a display rate converter; and measuring signal characteristics of signals provided at a receiver output.
