Abstract: Digital content encoded in a media file format may be presented by accessing the media file, reading parameters that describe the content, and processing the media file using the encoded parameters to “play” or generate output. Although the media file format may have multiple optional extensions, the media file generally includes one or more frames. Each frame may include a synchronized frame with the synchronized frame having a synchronized header, a video format indicator, an audio format indicator, a width indicator, a height indicator, a frame rate index, and a payload. Although the digital content may include different types and formats, the parameters used in the media file may be used to describe the digital content so that it may be processed independent of the underlying algorithm used. For example, multiple channels of audio signals may be described.

Abstract: The stream sourcing content delivery system goes to a database and builds a physical stream, based on a schedule. The stream source content delivery system works at a station ID (SID), finds the order of the delivery of content for the station based upon the schedule, and downloads a plurality of music files to its hard drive to enable play back. The stream source content delivery system then concatenates the files, to create stream, and awaits the request of one or more stream recipients. Some preferred system embodiments further comprise a fail-safe mode, whereby a loop of music is generated from the downloaded stream, and is delivered to one or more users when further access to content is interrupted, such that recipients experience an uninterrupted delivery of a plurality of files, e.g. songs.

Abstract: A multi-user vehicle telemetric system comprises vehicle interface units (VIUs), wireless gateways, and one or more central hosts. The VIU in a vehicle collects data over the OBD-II bus and stores the data in the form of DataPoint Records (DPRs) in an on-board non-volatile (e.g. flash) memory. When the VIU is within wireless range of a gateway, it establishes a WiFi (802.11b) connection with the gateway, and submits stored DPRs to the gateway, to be stored in permanent storage at the gateway. Although the DPRs are stored in permanent storage on the gateway, they are deleted from permanent storage on the gateway after they are successfully uploaded to the central hosts. The gateways are shared, and communicate with the central hosts over a wide area network (WAN). When a gateway has gathered new DPRs from a VIU, it submits these to selected central hosts.

Abstract: A method of determining fuel consumption in a vehicle through the OBDII bus is described. The fuel consumption is determined by using mass air flow (MAF) sensor data or manifold air pressure (MAP) sensor data, and obtaining and applying long term and short term fuel trim values for the vehicle, which respectively characterize deviations of air-to-fuel stoichiometry in the vehicle due to aging and vehicle's current operating conditions to determine the corrected fuel consumption in the vehicle. For MAP based method, an independent determining of Volumetric Efficiency of a vehicle's engine is also provided. The method is further enhanced by providing various sensing patterns for various sensor data, which depend on the rate of change of the respective data.

Abstract: A source accessed by a terminal may be changed by enabling a terminal to access a stream of data units on a first duplicating switch, determining that the terminal should access the stream from a second duplicating switch, and transitioning the terminal to the second duplicating switch to access the stream.

Abstract: Inserting audio content into one or more communications channels includes associating audio content with one or more corresponding triggers. A communications channel is established with an initiating device and a host, and a communications channel is established with a recipient device and the host. Voice communications are enabled to be exchanged, through the host, between the initiating device and the recipient device. A dual tone multi-frequency (DTMF) indicative of a pressed key on the device keypad is received from the initiating device. The audio content associated with the received IDTMF is identified based on the associated audio content with one or more corresponding triggers. The audio content identified as associated with the received DTMF is accessed. The accessed audio content is inserted in the communications channel with the initiating device and the host and the communications channel with the recipient device and the host.

The VIU in a vehicle collects data over the OBD-II bus and stores the data in the form of Data Point Records (DPRs) in an on-board flash memory. When the VIU is within wireless range of a gateway, it establishes a WiFi (802.11b) connection with the gateway, and submits stored DPRs to the gateway, to be stored in permanent storage at the gateway. The gateways communicate with the central host over a wide area network (WAN). When a gateway has gathered new DPRs from a VIU, it submits these to the central host. Databases in the gateways as well as in the central host are maintained and synchronized to track received DPRs by sequence number and originating VIU. In conjunction with specific protocols, all DPRs are thus collected reliably, even though communication with a vehicle may be intermittent. Efficient use of WiFi bandwidth is made by avoiding the unnecessary collection of duplicate DPRs.

Abstract: A method is provided which directs users to the closest mirror site for desired content. For each mirrored instance of a content store, the distance is determined to each of the networks from which users connect, wherein the determined distance is typically based upon the number of hops and or latency. The localization information is stored, such as by populating a localization database or a localization web service. Upon receipt of a user request for a web page that includes a link to localized/mirrored content, the stored localization information is queried, to determine the closest mirror to the user, based upon the IP address of the user terminal or network. A web page is then generated and transmitted to the user, which comprises a localized link to the determined mirror site. When the user selects the localized link, the user is automatically directed to the closest, i.e. local, mirror.
