  • Patent number: 9420023
    Abstract: An example method includes requesting a data stream using a buffer with an initial maximum window size for buffering received data associated with the requested data stream, receiving into the buffer one or more data segments associated with the data stream, removing from the buffer one or more data segments for use by a receiving device, and determining a current window size of the buffer, wherein the current window size is equal to the maximum window size less any data segments which have been received that have not been removed from the buffer. The method further includes comparing the current window size to a predetermined threshold, and in response to determining that the current window size is less than the predetermined threshold, increasing the maximum window size, and initiating a buffer size increase timer having a current timer value and a timer expiration value.

  • Patent number: 9414042
    Abstract: Video data is received in 2D or 3D format from different channels as a user scrolls through an electronic guide. The video data may be displayed in a portion of the on: screen display along with graphic and text associated with the EPG data. The received video data may be converted to a suitable format to be displayed with the Electronic Program Guide (EPG). The video data may be converted from 3D to 2D format to be displayed with the EPG data. The video data may be converted from 2D format to 3D format, while the EPG data displays in 2D format. The video data may be converted from one 3D format to another 3D format for display with the EPG data. Selection of converting the received video data can be based on a display format of a previously viewed channel prior to requesting the EPG to be displayed.

  • Patent number: 9386294
    Abstract: A method (300) and apparatus (400) for three-dimensional television (3DTV) image adjustment includes loading (342, 344) default 2D-to-3D image setting values from a default settings memory to a user adjustment settings memory, annunciating (346) the default 2D-to-3D image setting values, receiving (361, 362) a 2D-to-3D image settings value adjustment, saving (370) the 2D-to-3D image settings value adjustment in the user adjustment settings memory, and applying (390) the 2D-to-3D image settings value adjustment to a 2D-to-3D converted image. These methods and apparatuses allow individual users to set 3DTV image settings to their personal preferences to compensate for brightness reductions caused by 3DTV glasses, depth perception sensitivities, and other image quality factors.

  • Publication number: 20150341687
    Abstract: A content moving device which enables providing content stored on a first user device, such as a DVR, in a first format and resolution to be provided to a second user device, such as a portable media player (PMP) in a second format and resolution. The content moving device identifies content on the first user device as candidate content which may be desired by the PMP and receives the candidate content from the DVR. The content moving device transcodes the candidate content at times independent of a request from the PMP for the content. The content moving device may provide a list of available transcoded content to the PMP for selection, and provide selected content to the PMP. The content moving device may also provide information relating to any protection schemes of the content provided to the PMP, such as DRM rights and decryption keys.

  • Patent number: 8874634
    Abstract: Data are received at a receiving device from a server, where the data are encoded into one of a plurality of different versions, each version having a different fidelity level. A data stream having a buffer with an initial maximum window size for buffering received data is requested from the server, wherein the data stream initially has a first fidelity level. The maximum window size is managed to prevent the current window size from falling below a threshold that might trigger an adjustment by the server in the fidelity level of the data stream sent by the server, unless and until the accumulation of data in the buffer due to a decrease in the present processing capabilities of the controller of the receiving device falls below a threshold of processing power necessary for processing the data stream at the higher fidelity level for more than a transitory period of time.

  • Publication number: 20140143440
    Abstract: A method and apparatus for providing streamed media to client devices includes providing, for a client device, a variant playlist file that identifies a plurality of variant streams each corresponding to a different encoding of the same presentation but each presenting the same content having the same duration; and receiving, from the client device, a first request to provide a first set of identifiers that directs the first client device to a first set of media segments from a first variant stream of the plurality of variant streams in the variant playlist file, wherein the first set of media segments corresponds to a first encoding. The method further includes, responsive to the first request, providing a second set of identifiers that directs the client device to a second set of media segments, which corresponds to a second encoding, to use in downloading a first portion of the content.

  • Patent number: 8532462
    Abstract: A method, system, apparatus, article of manufacture, and computer program product provide the ability to non-destructively generate a file based master. A domestic source (having domestic audio and video content) with textless content (have portions of the domestic source that is devoid of text) is obtained. A localized source (e.g., localized audio-video) based on the domestic source is received. The localized video is compared to the domestic source to determine differences. The localized video is bladed and realigned with the domestic source. Metadata (of the differences) is transposed onto the domestic source. Texted portions in the domestic source are obscured with corresponding portions of the textless content. Texted material (based on the localized video and texted portions) is created. The localized video content and the textless content are discarded.
