20110235991 | MOVING CONTENT BETWEEN SET TOP BOX AND END DEVICES IN HOME - 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. The content moving device performs the often computationally intense and time consuming transcoding of user content to enable the user to move content between different user devices in a convenient manner. | 09-29-2011 |
20110273534 | Program Guide Graphics and Video in Window for 3DTV - 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 Electronic Program Guide (EPG). The video data may be converted from a 3D to a 2D format to be displayed with the EPG data. The video data may be converted from a 2D format to a 3D format, while the EPG data displays in a 2D format. The video data may be converted from one 3D format to another 3D format for display with the EPG data. The 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. | 11-10-2011 |
20120079054 | Automatic Memory Management for a Home Transcoding Device - 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 assigns a priority level to the content. The content moving device transcodes the candidate content in order of highest priority first and lowest priority last. The content moving device may also use the priority level to manage deletion of the transcoded content from the storage on the content moving device. The lowest priority level content may be deleted first as storage space is needed. | 03-29-2012 |

20130232228 | MANAGING ADAPTIVE STREAMING OF DATA VIA A COMMUNICATION CONNECTION - 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. | 09-05-2013 |
20140082144 | USE OF A RECEIVE-WINDOW SIZE ADVERTISED BY A CLIENT TO A CONTENT SERVER TO CHANGE A VIDEO STREAM BITRATE STREAMED BY THE CONTENT SERVER - A method for transmitting video streams from a server to a media device includes selecting by the server first encoding parameters for a first set of video streams based on a first current bandwidth capacity for a network and based on a first current window size of a receive buffer of the media device, and transmitting the first set of video streams from the server to the media device. The method includes selecting by the server second encoding parameters for a second set of video streams based on a second current bandwidth capacity for the network based on a second current window size of the buffer. The first current bandwidth capacity is different from the second current bandwidth capacity or the first window size is different from the second current window size. The method includes transmitting the second set of video streams from the server to the media device. | 03-20-2014 |
20140089469 | METHODS AND DEVICES FOR EFFICIENT ADAPTIVE BITRATE STREAMING - Methods and systems for a content server to select sets of video streams having different encoding parameters for transmitting the sets of video streams to a media device are disclosed herein. In some embodiments, a method for transmitting video streams for a media program from a server to a media device includes: selecting, by the server, first encoding parameters including a first bitrate for a first set of video streams for the media program based on a first estimated bandwidth capacity for a network linking the server and the media device, transmitting the first set of video streams from the server to the media device, determining, by the server, second encoding parameters including a second bitrate for a second set of video streams for the media program, and transmitting the second set of video streams from the server to the media device. | 03-27-2014 |
