A system for recording a compressed video-audio stream includes a decoder for decoding the video and audio packets of the stream, a multimedia recorder for recording the video and audio portions of the stream, and a video frame editor. In one embodiment the multimedia recorder receives and ignores initial delta frames of the video portion of the stream while buffering the audio portion of the stream received until a first key frame arrives and is buffered and decoded and wherein upon receiving a command to record, the system writes a copy of the key frame at a predefined interval the first interval corresponding with the start of the recording of the audio portions of the stream, the write interval repeated successively until a next key frame arrives whereby the video and audio is then recorded as received.

A method includes processing media content. The media content includes audio data corresponding to a first audio playback rate and video data corresponding to a first video playback rate. Processing the media content includes identifying a speech portion of the audio data. The speech portion includes a consonant portion. The method further includes producing modified media content. The modified media content is produced based on modifying the video data and modifying the audio data. Modifying the audio data includes applying a non-linear transformation to the speech portion identified in the audio data. The method further includes storing the modified media content.

In a recording medium on which is recorded a multiplexed stream including a plurality of first packets (V_main) constituting a first I-picture in a first video stream and a plurality of second packets (V_sub) constituting a second I-picture in a second video stream, information for identifying the first I-picture and information for identifying the second I-picture are recorded on the medium. A recording medium can thereby be obtained that enables the rapid detection, from a small amount of information, of a particular picture included in a stream such as a TS in which multiple content streams are multiplexed.

A digital security surveillance system allows a user to store selected security surveillance feeds while the user is simultaneously watching or reviewing another feed. User control commands are accepted and sent through the system. The system parses the resulting digital stream and generates identifying information associated with at least one video segment of the digital stream. The video segments are stored on a storage device. When a security surveillance feed is requested for display, a corresponding stored digital stream is found and its video segments are extracted from the storage device and sent to a decoder that converts the digital stream into display output signals. The security surveillance feeds can be simultaneously sent to an external storage device such as a DVD recorder or VCR.

A distributed database management system provides a central database resident on a server that contains database objects. Objects, e.g., program guide data, to be replicated are gathered together into distribution packages called slices, that are transmitted to client devices. A slice is a subset of the central database which is relevant to clients within a specific domain, such as a geographic region, or under the footprint of a satellite transmitter. The viewer selects television programs and Web content from displayed sections of the program guide data which are recorded to a storage device. The program guide data are used to determine when to start and end recordings. Client devices periodically connect to the server using a phone line and upload information of interest which is combined with information uploaded from other client devices for statistical, operational, or viewing models.

A signal processing apparatus includes one or more memories configured to store instructions, and one or more processors configured to execute the instructions to acquire first time information, perform signal processing on an acoustic signal to generate first acoustic data including the acquired first time information, measure processing time for the signal processing based on the acquired first time information and the first acoustic data, acquire second time information indicating a time after measuring the processing time, perform signal processing on the acoustic signal to generate second acoustic data that does not include the first time information and the acquired second time information, correct the second time information based on the processing time, and record the second acoustic data synchronized in time with the corrected second time information.

Module compression/encoding plural images for recording, or an image recording apparatus or image recording system including the module. At least two first and second image input module types capture an image of frames from a video signal source, and convert into digital image data for output; an image input arbitration module arbitrates to place digital image data provided by the first type before digital image data provided by the second type. The first type image input module is provided with a real-time image. The apparatus or system further includes: a memory module temporarily storing the real-time image by a processing time for the arbitration module to process digital image data provided by the second type of image input module, an image encoding module compressing and encoding the digital image data, and changing a processing speed to perform a process of compression an encoding more in real time.
