Virtual playback speed modification

A multispeed playback system is described herein that allows for playback of smooth streaming media presentations at speeds other than the normal speed or direction, while still using an underlying platform that does not natively support multispeed. The system provides frames to the underlying platform so that the platform is still playing 1× content while the system manipulates video and/or audio samples being fed to the platform to make rendered data look appropriately for a selected speed and direction. The system may feed the underlying platform frames at a faster rate or skip every other frame for faster playback, or may feed each frame to the underlying platform multiple times for slower playback. Thus, the multispeed playback system allows a client application developer to provide users with expected multispeed playback at the client without encoding multiple different streams at the server.

Method for efficient processing of BTP enabled MPEG4 stream

A system is provided for providing a trickplay operation using a digital video recorder (DVR) when the video includes Broadcom Transport Packets (BTPs) designed for MPEG-2, but in an MPEG-4 video steam. In a first embodiment, to enable trickplay to function properly with MPEG-4 video, the BTP descriptors included with each group of data frames are disabled so that a single descriptor provided without BTPs that would otherwise be provided in MPEG-4 is all that remains. In a second embodiment, the 5 descriptors for MPEG-4 are combined into a single descriptor. In a third embodiment, the pace of decoding of the MPEG-4 descriptors is increased so that the speed of encoding all the 5 descriptors is comparable to the pace of decoding a single MPEG-2 descriptor.

There is provided an information processing apparatus, an information processing method, a recording medium, a playback apparatus, a playback method, and a program that are designed to prevent an unnatural change in luminance during random access. The information processing apparatus according to one aspect of the present technology generates dynamic metadata including information regarding luminance of a picture, and encodes HDR video data such that the dynamic metadata is added to each picture serving as a random access point. For example, the dynamic metadata can be allowed to be added to the first picture of a GOP, the first picture serving as the random access point during fast-forward playback/rewind playback or cueing playback. The present technology can be applied to a Blu-ray (registered trademark) Disc player.

Systems and methods for recording and playing back programs having desirable recording attributes

Systems and methods for recording multiple copies of a program are provided. The method may include receiving a user instruction to record a program. A determination may be made to record multiple copies of the program. In response to the determination, multiple copies of the program may be recorded. A user instruction to display the recorded program may be received. A copy of the program may be played back. The user may switch to another copy of the recorded program if the original copy lacks desirable recording attributes, or the interactive television application may automatically switch to another copy of the program.

USER CONTROL FOR DISPLAYING TAGS ASSOCIATED WITH ITEMS IN A VIDEO PLAYBACK

A video scene is displayed in a either a tag mode or a tagless mode. The video scene depicts a plurality of visually perceptible items. The tag mode displays one or more visually perceptible tags in conjunction with the video scene. Each tag is associated with a visually perceptible item appearing in the video scene. The tags are categorized into a plurality of categories. In response to a request to display the video scene in the tag mode for a first one of the plurality of categories, the display device displays the video scene in the tag mode displaying tags in the first one of the categories. In response to a request to display the video scene in the tag mode for a second one of the plurality of categories, the display device displays the video scene in the tag mode displaying tags in the second one of the categories.

TOUCH GESTURE CONTROL OF VIDEO PLAYBACK

A method of touch gesture control of video playback is discloses. The method includes providing a video item for playback The method also receives an indication of a touch gesture made by a user of mobile user device. The method further determines whether the touch gesture is a swipe gesture within a portion of a user interface (UI) including a media player to play the video item. The method also moves the playback of the video item from a first point in time to a second point in time by a predetermined amount of time in response to determining the touch gesture is the swipe gesture within the portion of the UI comprising the media player.

A set-top box apparatus includes at least one input module to receive one or more media content streams, at least one memory device, an Ethernet port, at least one wireless transceiver to access a communications network to enable communication with at least one external media player device, an HDMI connector to provide a communication path to a multimedia presentation device, wherein the set-top box apparatus is configured to process at least one of the received one or more media content streams from the at least one input module into multimedia data, to send the one or more received media content streams to the at least one memory device to be stored, and to convey the multimedia data on the communication path to the multimedia presentation device.

Marking media files

Methods, systems, and products insert markers into recorded media modules. A pair of reference points is received that marks a position and another position in a recorded media module. A copy of the recorded media module is retrieved from memory. Portions of the copy of the recorded media module occurring before the position, and occurring after the another position, are discarded. The copy of the recorded media module occurring between the position and the another position is then presented to a user.

Persistent review buffer

A method of content recording and playback is carried out in a receiving device by selecting one of a plurality of digital content streams (80, 82, 84), which have respective distribution arrangements. A content segment (90) of a review buffer (88) is established and configured for the one content stream. While recording the one content stream in the review buffer (90), a content source change operation is performed to record another content stream in the review buffer (88) by discontinuing recording of the one content stream, and iterating establishing, configuring and recording with a new content segment (92). Recorded content of the content segment (90) and new content segment (92) are stored in respective data stores (102, 100). The content streams may be replayed in an order or a reverse order of recording thereof by retrieving data from respective content segments or data stores. Related apparatus is also described.

Information reproduction system, information reproduction method, information reproduction device, and access analysis device

A system, a method, and a device that can reproduce a reproduction target file recorded on a portable information recording medium and a network file acquired in response to a request of a content application are provided. In the system including video reproduction devices, the vehicle-mounted video reproduction device transmits an NF entry transmission request, stores a received NF entry as an NF table, acquires in advance an NF on the basis of a stored NF entry and stores it, and if it is determined that an NF entry corresponding to a reproduction target file exists in the NF table when an optical disc is reproduced in a player unit, executes a proxy response for reading an NF identified by the NF entry corresponding to the reproduction target file from an NF storage unit and for supplying it to the player unit.
