The signal is then stored and distributed. When attempts are made to use or access the signal, the signal is checked for the presence of a watermark containing the digital signature for the desired portion of the signal. If the watermark is found, the digital signature is extracted and used to verify the authenticity of the desired portion of the signal. If not found, the signal is checked for the presence of the strong watermark, which if found causes the system to inhibit further use of the signal, and if not found further use of the signal is allowed.

A system and method disposed to enable encoding, decoding and manipulation of digital video with substantially less processing load than would otherwise be required. In particular, one disclosed method is directed to generating a compressed video data structure that is selectively decodable to a plurality of resolutions including the full resolution of the uncompressed stream. The desired number of data components and the content of the data components that make up the compressed video data, which determine the available video resolutions, are variable based upon the processing carried out and the resources available to decode and process the data components. During decoding, efficiency is substantially improved because only the data components necessary to generate a desired resolution are decoded. In variations, both temporal and spatial decoding are utilized to reduce frame rates, and hence, further reduce processor load. The system and method are particularly useful for real-time video editing applications.

According to an embodiment, an information processor includes a first decoder, a controller and a display unit. The first decoder decodes the first video encoded data at a first speed to generate a first video. When the first video encoded data is received earlier than the second video encoded data, the controller controls the first speed so as to generate a period in which the first speed becomes lower than a ×1 speed until second time information of the second decoder catches up with first time information of the first decoder. When the first video encoded data is received earlier than the second video encoded data, the first video is displayed at the first speed until the second time information catches up with the first time information.

In automotive networking applications, data about vehicle's environment can be used in conjunction with a control policy to manage the performance and power usage of a networked device. The control policy can dynamically adjust the balance between link power and performance of the device's communications interface by taking into account the vehicles current situation and user preferences, e.g. location, destination, speed, sensor status, or the like. Controlling the balance between link power and performance of networked devices can be important in maximizing power savings without unacceptably decreasing network performance.

In various embodiments, an iterative encoding application encodes a source video sequence. The encoding optimization application generates a set of shot encode points based on a set of encoding points and a first shot sequence included in the source video sequence. Each shot encode point is associated with a different encoded shot sequence. The encoding optimization application performs convex hull operation(s) across the set of shot encode points to generate a first convex hull associated with the first shot sequence. Subsequently, the encoding optimization application generates encoded video sequences based on the first convex hull and a second convex hull associated with a second shot sequence included in the source video sequence. The encoding optimization application computes a new encoding point based on the encoded video sequences and a target value for a first video metric and then generates an optimized encoded video sequence based on the new encoding point. 1. A computer-implemented method for playing back digital content on an endpoint device , the method comprising:receiving an encoded video sequence comprising a plurality of encoded frame sets, each encoded frame set being encoded at an associated resolution and encoding parameter value based on a predefined metric value;decoding at least a portion of the encoded video sequence to generate a decoded video sequence; andplaying back at least a portion of the decoded video sequence.2.
