A user can simply and easily change the contents of the Next control data set by operating the Next change operating section, and operability can be improved.

Abstract: Dynamically allocating virtual or physical CPU cycles for use in processing a video stream. Video complexity information for two or more digital video streams actively being processed by one or more video encoders is determined at periodic intervals. Video complexity information describes the complexity of digital video carried by the digital video streams across a bounded number of consecutive digital frames which includes digital frames not yet processed by the one or more video encoders. A determination is made as to whether a number of CPU cycles allocated for processing a particular digital video stream should be adjusted based on the determined video complexity information. The number of CPU cycles allocated for processing the particular digital video stream may be dynamically adjusted by changing an amount of CPU cycles allocated to a virtual machine in which the stream is processed or by processing the stream in a different virtual machine.

Abstract: Display with an appropriate luminance dynamic range is realizable on a receiving side. A gamma curve is applied to input video data having a level range from 0% to 100%*N (N: a number larger than 1) to obtain transmission video data. This transmission video data is transmitted together with auxiliary information used for converting a high-luminance level on the receiving side. A high-level side level range of the transmission video data is converted on the receiving side such that a maximum level becomes a predetermined level based on the auxiliary information received together with the transmission video data.

Abstract: A system includes a primary playback system and a secondary playback system. The primary playback system plays back selected content. The secondary playback system plays back supplemental media associated with the content played back on the primary playback system. A media playback function (such as associated with the secondary playback system) monitors playback of the content on the primary playback system. For example, a first processing thread of the media playback function initially synchronizes playback of supplemental media on the secondary playback system with respect to playback of the content on the primary playback system. Based on further monitoring of playing back the content on the secondary playback system, a second processing thread of the media playback function verifies synchronization (and, when needed, initiates re-synchronization) of playback of the supplemental media on the secondary playback system with respect to playback of the content on the primary playback system.
