Abstract: Embodiments facilitating mixed service use of bonded satellite transponders in communication systems are provided. An apparatus comprises a first multiplexer configured to receive first content from first channels of a first type of channel, a second multiplexer configured to receive second content from second channels of a second type of channel, and a transport stream processor (TSP). The TSP can be configured to output the received first content and the second content to modulators respectively associated with different channels for transmission of the first type of channel and the second type of channel, wherein the different channels are transmitted to a bonded satellite transponders, which transmits to a receiver. In some embodiments, the apparatus can comprise a multiplexer aggregator coupled between the TSP and the first multiplexer and the second multiplexer. The first content can be high bit-rate information and the second content can be lower bit-rate information.

Abstract: Methods and apparatus for broadcasting high quality audio “studio direct” with the same digital information employed in the studio by the video producer with AC-3 digital audio signals for broadcast to integrated receiver decoders (IRD). The methods and apparatus permit proper handling of AC-3 data by switching signals to encoders in response to detection of the encoded signals representing compression of the data. Control over individual data bits such as copyright bits is maintained by determining the bit status, comparing it to a preferred status, changing the status if it does not comply with the preferred status, and reevaluating cyclical redundancy check value in each data packet to avoid disruption in the data transmission. In addition, the system includes an uplink device which automatically checks, logs and reports errors in Dolby Digital AC-3 signals by a monitor which employs a processor, a digital audio card and an SMPTE timecode reader.

Abstract: Content delivery systems and methods to operate the same are disclosed. A disclosed example content delivery system comprises: a receiver station; a content server to transfer a file to a receiver via a point-to-point communication signal; and a transmission source that includes a computer readable medium to store the file containing pre-packetized content data and a controller to send the file containing the pre-packetized content data to a broadcast transmitter and to the content server.

Abstract: Audio level control is provided for compressed audio. Scale factors for the compressed audio are extracted from an MPEG audio data stream, the extracted scale factors are altered without decompressing the compressed audio, and the MPEG audio data stream is updated with the altered scale factors. All of the scale factors in the MPEG audio data stream are altered based on a parameter identifying how the gain levels in the MPEG data stream are to be altered.

Abstract: A system and method for merging of multiple encoded audio and video streams into a single program in the transport stream enables playback of any audio stream with any video stream. This is accomplished by first locking the frequency of audio and video input streams for a plurality of different programs to a source clock, independently encoding each program with its own PCR and PTS into a program stream, multiplexing the program streams into a transport stream, and then synchronizing the PCR and PTS of the program streams to a declared master PCR.

Abstract: Server accessible case records are generated for post-diagnostic and remote access viewing. First, a master sequence of digital video images is recorded. Next, a post-diagnostic case record is generated including a sequence of thumbnail images and a single lossless still image selected from the master sequence of images. The images of the post-diagnostic case record are formatted to be accessible by a browser over a dial-up connection. Each image of the sequence of thumbnail images includes a selection of interior pixels of one of the digital video images of the master sequence. The sequence of thumbnail images is a selection of consecutive images from the master sequence. The post-diagnostic case record and the master sequence are then stored on an image server. The master sequence is archived onto a secondary archive medium after a predetermined time.
