A video compression framework based on parametric object and background compression is proposed. At the encoder, an embodiment detects objects and segments frames into regions corresponding to the foreground object and the background. The object and the background are individually encoded using separate parametric coding techniques. While the object is encoded using the projection of coefficients to the orthonormal basis of the learnt subspace (used for appearance based object tracking), the background is characterized using an auto-regressive (AR) process model. An advantage of the proposed schemes is that the decoder structure allows for simultaneous reconstruction of object and background, thus making it amenable to the new multi-thread/multi-processor architectures.

System and method for object based parametric video coding

A device may include a communication interface configured to receive a request from a client device, where the request identifies a first video on demand (VOD). The device may also include logic configured to identify capabilities associated with the client device, the capabilities including at least one of a decoding capability of the client device, a content protection scheme supported by the client device, or a transport protocol via which the client device can communicate, and forward the request for the VOD to a service provider associated with providing the first VOD. The logic may also be configured to receive a media stream from the service provider, the media stream corresponding to the first VOD, process the media stream in accordance with the identified capabilities, and forward the processed media stream to the client device.

Video on demand processing

Exemplary customer premises equipment ('CPE') diagnostic, recovery, and reporting systems and methods are disclosed herein. An exemplary method includes a technical support server subsystem aggregating, over time, technical support data representing technical issues of CPE devices and operations performed to resolve the technical issues, identifying a subset of the technical support data, and providing the identified subset of the technical support data to a CPE device for local storage by the CPE device, locally stored technical support data configured to be used by the CPE device to self-recover from a future technical issue associated with the CPE device. In certain embodiments, the CPE device may be configured to function as a media server device and/or as an intermediary technical support device at a customer premises. Corresponding methods and systems are also disclosed.

Customer premises equipment diagnostic, recovery, and reporting systems and methods

A computing device receives instructions, from a user, to send an email message and determines if the email message includes an attachment. When the email message does not include an attachment, the computing device conducts a scan of text of the email message for implications that an attachment should be included. When the email message includes an attachment, the computing device conducts a scan of the email text for implications of a particular type of attachment. The computing device provides, to the user, a notification when there is a positive result from the scan of the email text for implications that an attachment should be included or from the scan of the email text for implications of a particular type of attachment.

Email attachment helper

A system is configured to receive, from a user device, a request for video content and closed captioning content associated with the video content; obtain, based on the request, device information that identifies a first video format that is supported by the user device; obtain the video content and the closed captioning content, where the video content conforms to a second video format, and where the closed captioning content conforms to a text format; convert the video content from the second video format to the first video format and the closed captioning content from the text format to the first video format; and transmit the converted video content and the converted closed captioning to the user device, where the converted video content and the converted closed captioning content enable the user device to play the converted video content and the converted closed captioning content without modifying the user device.
