A system and method dynamically supporting the concurrent storage of both quadrature amplitude modulated formatted and Internet protocol formatted video content. In particular, this dynamic support is based, at least in part, upon the recognition of format of the content being stored or retrieved from a memory. This memory is typically a hard-disk drive associated with a media gateway appliance. The system and method enable the provision of an improved content viewing and storage experience for users.

System and method for adaptive storage of video data

A system and method enabling the seamless transition between viewing a recorded portion of a program and rejoining a live stream of that program. The system and method enable the rapid provision of live-streamed content upon the exhaustion of the playback of recorded content. This achieved by utilizing a universal resource locator associated with the source of the content.

System and method for seamless content transition

A system and method enabling an upgraded digital recorder to detect, retrieve, decrypt, encrypt and securely store digital content retrieved from one or more legacy digital recorders. The legacy digital recorder is placed into a mode permitting access to stored digital content. An upgraded digital recorder then interfaces with the legacy digital recorder and mutual authentication is performed. Following successful authentication, the upgraded digital recorder disables most of the legacy digital recorder's functionality. Utilizing a digital key protecting the stored content from unauthorized access, the upgraded digital recorder retrieves and decrypts the digital content from the legacy digital recorder. The decrypted content is then analyzed and if needed converted to a format compatible with the upgraded digital recorder. The digital content is then indexed, encrypted and stored in the upgraded digital recorder. This process can be enabled via head-end provisioning and therefore requires little or no consumer or technician participation.

System and method for the migration of legacy digital content

Methods, systems, and computer readable media may be operable to facilitate an anticipation of an execution of a process termination tool. An allocation stall counter may be queried at a certain frequency, and from the query of the allocation stall counter, a number of allocation stall counter increments occurring over a certain duration of time may be determined. If the number of allocation stall counter increments is greater than a threshold, a determination may be made that system memory is running low and that an execution of a process termination tool is imminent. In response to the determination that system memory is running low, a flag indicating that system memory is running low may be set, and one or more programs, in response to reading the flag, may free memory that is not necessary or required for execution.

Low system memory detection

A system and method dynamically adjusting the rate at which incoming content data is transferred into a media gateway appliance, and the rate at which outgoing content data is provided to one or more client devices by the media gateway appliance. This dynamic adjustment is performed in accordance with a predetermined program and as a function of real-time data streaming rates and predetermined rate parameters and preferences. The system and method enable the provision of an improved viewing and content acquisition experience for users.

System and method for dynamic adjustment of content streaming rates

A method of processing a sequence of coded video frames conveyed by a digital data stream, where each frame represents an image, includes receiving the sequence of coded video frames at a recording device, determining a frame interval between presentation of an ith coded frame of the sequence and an (i+1)th coded frame of the sequence, calculating a stream time stamp for the ith coded frame, and calculating a stream time stamp for the (i+1)th coded video frame based on the stream time stamp for the ith coded video frame and the previously determined frame interval.

Method of processing a sequence of coded video frames

A method and apparatus is provided for recording a program. The method includes storing, in response to a user request, at least one content file that includes first and second program segments that are spliced to form a single program. At least one index file is created and stored. The file index includes program specific information associated with the first and second program segments. The index file also includes an identification of a splice point denoting a transition between the first and second program segments. In addition, a splice index is created and stored. The splice index includes timing information specifying a time at which the splice point occurs.

Digital video recorder recording and rendering programs formed from spliced segments

Systems and methods for a self-correcting DVR record pipeline may provider for simpler, lower cost transport producer hardware elements. A free running transport pipeline producer may fill transport buffers without waiting for feedback from the data consumer that data has been completely processed. The pipeline data consumer independently detects transport buffers that are overwritten before processing on the buffer content is complete. The pipeline data consumer drops or deletes any invalid content or stream data to recover from the data overflow condition.

Self correcting record pipeline

A method of modifying a digital data stream composed of a sequence of frames, where each frame represents an image and includes a data field specifying a presentation time stamp value for the frame. If there is a discontinuity in presentation time stamp value between a next frame and a first frame, a value representing a stream time stamp of interest is assigned to a variable for representing the value of the stream time stamp of interest at a point of discontinuity in presentation time stamp, and a value of the presentation time stamp is assigned to a variable for representing the first frame's clock time based on presentation time stamp, and the next frame is stored in a database using as an index the value representing a stream time stamp of interest.
