20110173345 | Method and system for HTTP-based stream delivery - A method of delivering a live stream is implemented within a content delivery network (CDN) and includes the high level functions of recording the stream using a recording tier, and playing the stream using a player tier. The step of recording the stream includes a set of sub-steps that begins when the stream is received at a CDN entry point in a source format. The stream is then converted into an intermediate format (IF), which is an internal format for delivering the stream within the CDN and comprises a stream manifest, a set of one or more fragment indexes (FI), and a set of IF fragments. The player process begins when a requesting client is associated with a CDN HTTP proxy. In response to receipt at the HTTP proxy of a request for the stream or a portion thereof, the HTTP proxy retrieves (either from the archive or the data store) the stream manifest and at least one fragment index. Using the fragment index, the IF fragments are retrieved to the HTTP proxy, converted to a target format, and then served in response to the client request. The source format may be the same or different from the target format. Preferably, all fragments are accessed, cached and served by the HTTP proxy via HTTP. In another embodiment, a method of delivering a stream on-demand (VOD) uses a translation tier (in lieu of the recording tier) to manage the creation and/or handling of the IF components. | 07-14-2011 |
20110296048 | Method and system for stream handling using an intermediate format - A method of delivering a live stream is implemented within a content delivery network (CDN) and includes the high level functions of recording the stream using a recording tier, and playing the stream using a player tier.

20120265853 | FORMAT-AGNOSTIC STREAMING ARCHITECTURE USING AN HTTP NETWORK FOR STREAMING - This patent document describes, among other things, distributed computer platforms for online delivery of multimedia, including HD video, at broadcast audience scale to a variety of runtime environments and client devices in both fixed line and mobile environments. The teachings hereof can be applied to deliver live and on-demand content streams via computer networks. The teachings also relate to the ingestion of content streams in a given source format and the serving of the stream in a given target format. For example, a system might have machines in a content delivery network that ingest live streams in a source format, use an intermediate format to transport the stream within the system, and output the stream in a target format to clients that have requested (e.g., with an HTTP request) the stream. The streams may be archived for later playback. | 10-18-2012 |
20120275597 | Extending data confidentiality into a player application - In a content protection scheme, and in response to a request for a content segment received by a server, the server generates and associates with the segment a message that confers entitlement to a session-specific key from which one or more decryption keys may be derived. The decryption keys are useful to decrypt the segment at runtime as it is about to be rendered by a player. Before delivery, the server encrypts the segment to generate an encrypted fragment, and it then serves the encrypted fragment (and the message) in response to the request. At the client, information in the message is used to obtain the session-specific key. Using that key, the decryption keys are derived, and those keys are then used to decrypt the received encrypted fragment. The decryption occurs at runtime. The approach protects content while in transit to and at rest in the client browser environment. | 11-01-2012 |
20140337958 | SECURITY FRAMEWORK FOR HTTP STREAMING ARCHITECTURE - Methods and apparatus for preventing unauthorized access to online content, including in particular streaming video and other media, are provided. In various embodiments, techniques are provided to authorize users and to authenticate clients (e.g., client media players) to a content delivery system. The content delivery system may comprise a content delivery network with one or more content or “edge” servers therein. The requesting client is sent a program at the time of content delivery. The program may be embedded in the content stream, or sent outside of the stream. The program contains instructions that are executed by the client and cause it to return identifying information to the content delivery system, which can then determine whether the client player is recognized and, if so, authorized to view the content. Unrecognized and/or altered players may be prevented from viewing the content. | 11-13-2014 |

20120217978 | BACKGROUND NOISE MEASUREMENT AND FREQUENCY SELECTION IN TOUCH PANEL SENSOR SYSTEMS - A touch panel sensor system that can dynamically measure noise and automatically switch to a frequency with minimal noise is described. The touch panel sensor system includes a sensor configured to detect a change in capacitance associated with a touch upon a touch panel. The system also includes a drive module configured to generate a drive signal having a first waveform characteristic (e.g., signal having a periodic waveform characteristic) during a first phase (e.g., sensor phase) and a second drive signal having a second waveform characteristic (e.g., constant voltage signal) during a second phase (e.g., noise detection phase). The first and second drive signals are configured to drive the sensor. The system also includes a measuring module coupled to the sensor that is configured to measure noise having the first waveform characteristic (e.g., periodic waveform characteristic) during the second phase. | 08-30-2012 |
20120293455 | TOUCH PANEL TESTING USING MUTUAL CAPACITOR MEASUREMENTS - A capacitive touch panel is tested for the presence or absence of short and open circuits in drive and sense lines without the use of a tool that touches the surface of the panel. During a first stage of testing, drive lines of the touch panel are sequentially driven while the remaining drive lines are floated. Sense lines are read to indicate whether a driven drive line is shorted to an adjacent drive line, an open circuit, or coupled to a sense line that is an open circuit. During a second stage of testing, drive lines are driven while alternate sense lines are floated or enabled. The signals on the enabled sense lines are acquired to indicate whether the enabled sense lines are shorted to adjacent sense lines. This second stage can be repeated, switching the roles of the sense lines, to determine the locations of short and/or open circuits. | 11-22-2012 |
20130207923 | CAPACITIVE TOUCH PANEL HAVING PROTRUSIONS FORMED BETWEEN DRIVE AND/OR SENSOR ELECTRODES - A capacitive touch panel includes elongated drive electrodes arranged next to one another and having a characteristic spacing between adjacent drive electrodes. The capacitive touch panel also includes elongated sensor electrodes arranged next to one another across the drive electrodes and having a characteristic spacing between adjacent sensor electrodes. The drive electrodes and/or the sensor electrodes have protrusions into the spaces between adjacent electrodes. The characteristic spacing between the sensor electrodes may be at least substantially greater than the characteristic spacing between the drive electrodes. The sensor electrodes may have a pitch based upon a touch diameter of a finger, and the touch panel may be capable of sensing a stylus having a touch diameter substantially less than the touch diameter of the finger. | 08-15-2013 |
20130207924 | CAPACITIVE TOUCH PANEL FOR MITIGATING AND/OR EXAGGERATING FLOATING CONDITION EFFECTS - A capacitive touch panel includes elongated drive electrodes arranged next to one another and elongated sensor electrodes arranged next to one another across the drive electrodes. Together, the drive electrodes and the sensor electrodes define a coordinate system where each coordinate location comprises a capacitor formed at an intersection between one of the drive electrodes and one of the sensor electrodes. In implementations, the drive electrodes and/or the sensor electrodes are configured to block capacitance between a touch at a coordinate location and the drive electrodes during a floating condition for the panel. In other implementations, the drive electrodes and/or the sensor electrodes are configured to exaggerate capacitance between a touch at a coordinate location and the drive electrodes during a floating condition for the panel. | 08-15-2013 |
