    摘要: A method and apparatus detects (516) a baud rate in a digital signal (442). An N-state counter (404) counts at a rate N times the baud rate and the digital signal is sampled (504) to detect transitions of the digital signal. N tallies (202) record how many transitions occur coincident with each of the states of the counter, and a total number of transitions detected is computed (508). M groups (204-210) of the tallies are formed (510) corresponding to contiguous sequential states of the counter, and for each group a group number is calculated (512) indicating how many transitions are recorded in the tallies of the group. Each group is defined (514) transitional if the group number exceeds a percentage (413) of the total number of transitions, and the baud rate is determined present or absent based upon the groups that are defined as transitional.

    摘要: A system and method for adding images to a wireless audio service. The invention is adapted for use in a system for wirelessly transmitting and receiving an audio data stream and includes an arrangement for providing an image and a mechanism for inserting the image into the data stream prior to transmission thereof. In the illustrative embodiment, a third arrangement is provided for receiving and decoding the data stream to extract and a fourth arrangement is included for displaying the image while the audio signal is output. The fourth arrangement may be a digital radio, i.e., a radio adapted to process digital signals, such as a satellite radio, high definition radio, digital AM or other suitable primarily audio wireless communication system. In a specific embodiment, the invention includes an arrangement for automatically inserting a selected image in the stream. In the illustrative embodiment, this arrangement includes a source selector, an image editor coupled to the source selector, an image resizer, an image compressor, and an arrangement for allowing a user to add text, color, style and/or other information to an image output by the compressor. The invention further includes an arrangement for adding images from an archive to the stream and a graphical picture show composer for providing an image queue. An image server is included for feeding the image queue to the output data stream provided by a system server such as an XM or Sirius satellite radio server.

    摘要: A novel and useful apparatus for and method of securely downloading and installing a patch program in a processing device. Each processing device is assigned a unique key embedded therein during manufacture and has knowledge of a shared key. The program patch is encrypted using the shared key and transmitted over a communication link, such as a satellite radio link, to each device. The patch is decrypted using the shared key and re-encrypted using the unique key known only to the device itself. The re-encrypted patch program is stored in nonvolatile memory and upon reset of the device, the encrypted patch contents are read out of the nonvolatile memory, decrypted using the unique key and loaded into patch memory for execution by the processing device.

    摘要: Apparatus and methods for providing both commercial-free content and commercially sponsored content in a flexible manner to various subscriber classes of digital audio radio are presented. In exemplary embodiments of the present invention, lower tier subscribers can, for example, sample commercial free content as experienced by higher tier subscribers by means of flexible channel authorization. In exemplary embodiments of the present invention new non-subscribers can be allowed to sample some of the commercial content (such as, when, for example, a default UPC is stored in the radio before shipment) before choosing to subscribe. In exemplary embodiments of the present invention, a digital audio radio (receiver) can include a controller operable to receive and store an Uplink Package Code (UPC) in the digital audio radio. The radio can be further operable to receive, for example, a broadcast Package Definition Message (PDM) that maps the stored UPC to a list of authorized channels (obtained via a broadcast Package Authorization List (PAL)) for that receiver. In exemplary embodiments of the present invention, a method of channel authorization for digital audio radios can include assigning an Uplink Package Code (UPC) to, and storing the UPC in, a digital audio radio and receiving a broadcast Package Definition Message (PDM) that maps the UPC to a list of authorized channels (from a Package Authorization List (PAL)).
