A method and apparatus for secure transfer and playback of multimedia content enables the secure transfer of multimedia content from a digital video recorder (DVR) to a personal computer (PC) and further to a handheld device. A DVR determines which devices on a Local Area Network (LAN) are authorized to share and/or retrieve content from the DVR. The DVR receives a connection request from a PC on the LAN, authorizes the connection request and establishes a secure connection between the DVR and the PC. Once the secure connection is established, the DVR receives a request for multimedia content from the PC, prepares the multimedia content for transfer and transfers the multimedia content to the PC.

A MSS chunking method for an MP4 file, an MSS adapter, and a non-transitory computer-readable storage medium are disclosed. The method may include: receiving an MSS download request for downloading of at least one MSS chunk of a first MP4 file; determining, according to MSS chunk indexes and virtual chunk indexes of the first MP4 file, data segments in the first MP4 file corresponding to data of the at least one MSS chunk, each MSS chunk index containing a playing address of a respective MSS chunk of the first MP4 file, and each virtual chunk index containing a correspondence between the data of a respective MSS chunk and a respective one of data segments of the first MP4 file; sending a data segment download request to a media server and receiving data segments; and assembling contents of the data segments to generate the at least one MSS chunk.

Mechanisms for presenting media content items using multiple devices are provided. In some embodiments, methods for presenting media content are provided that include: detecting an offer to initiate a purchase of a content item being presented using the media device, wherein the media device has not been authenticated with a content service that provides the content item; in response to detecting the offer to initiate the purchase of the content item when the media device has not been authenticated with the content service that provides the content item, causing the media device to be discoverable by one or more mobile devices that are connected to a same local area network as the media device; encoding offer data corresponding to the detected offer to initiate the purchase of the content item; in response to receiving a status request from a mobile device that is connected to the same local area network as the media device, transmitting the encoded offer data associated with the purchase of the content item to the mobile device, wherein the encoded offer data causes a payment user interface to be presented on the mobile device; receiving a cast request from the mobile device to cast the content item on the media device; and in response to the cast request, executing a receiver application on the media device that accepts the cast request from the mobile device and causes the content item to be presented using the media device.

Methods and systems for routing key commands received from a remote-control device are provided. The method and/or system may include receiving, at a device, a key command from the remote-control device, generating a first message that includes the key command, sending, from the device, the first message to a keystroke router, and determining, at the keystroke router, a system network controller associated with the device. Moreover, the keystroke router may send the key command to the system network controller.

Providing and using a branching narrative content service can include receiving from a user device a request for branching narrative content including a first segment. A live manifest can be generated with time metadata, a first content segment identifier that identifies a first content segment of the first segment, and a second content segment identifier that identifies a second content segment of the first segment. The live manifest can be provided to the user device, the user device obtaining the first content segment and the second content segment using the content segment identifiers. The user device obtains a selection of a branch while the first segment is being played and an updated live manifest is generated with updated time metadata and a third content segment identifier. The user device obtains the third content segment using the third content segment identifier and plays the second segment at the user device.

A method and apparatus for performing an integrated search is provided. An interface is provided that allows users to search and select any data related to a searchable term. Searchable terms may comprise titles of content, actors, and tags. Upon receiving results from the initial search, the user progresses through the initial search by selecting a result from the initial search and conducting a further search of that selection. The search may progress through many layers of searching in order to find information useful to the user and the user may perform actions based upon results of the search. The search implements a display with two columns, the first column displaying selectable data, and the second column displaying results to the selected data. The search is further customizable based upon a privacy level selected by the user.

Systems and methods for providing access to media content by connecting, to a public device, a private device that has an installed application associated with the media content. A media guidance application may receive a communication from a private device, running a private interface application, requesting to access content using the public device. In response, the media guidance application may retrieve, at the public device, a public interface application associated with the private interface application, from a content provider of the content. The private interface application may be configured to control a graphical user interface of the public interface application. Accordingly, the user may be able to access content via the public device when the private device is within a predetermined proximity to the public device.

A method and an apparatus for data interaction in a live room are provided, which relate to the field of livestream technology. According to the method, a first interaction control is displayed on a first live streaming interface of the live room in response to trigger information sent by a server being obtained, the trigger information indicating that amount of interaction data in the live room exceeds a preset threshold; and a first interaction panel is displayed on the first live streaming interface in response to a trigger operation on the first interaction control being received. An audience and an anchor in the live room interact with each other through the first interaction panel.

Disclosed are a video transmission method, a client, and a server. The method includes: a recommended viewport for playing a virtual reality (VR) video is determined; and at least one video file corresponding to the recommended viewport is requested from a server.

Systems and methods are disclosed herein for storing configuration data as a set of master data and override data where one set of configuration data is defined as the master and every other set of configuration data is defined as override configuration data. A media guidance application may generate master configuration data including the most common configuration data used in the geographical region served by the media guidance application, and number of override configurations which contain only those data which differ from the master configuration data for a number of sub-regions of the geographical region. This reduces duplicative configuration data, and the media guidance application need only store one full set of configuration data, namely the master configuration data, and a number of smaller override configurations.
