A multimedia streaming service presentation method based on Hypertext Transport Protocol streaming, a related apparatus, and a related system are provided. The multimedia streaming service presentation method based on HTTP streaming includes: obtaining a media presentation description file of a multi-stream multimedia streaming service i; obtaining n1 multimedia streams of N multimedia streams from a content server; presenting X presentation objects formed by the n1 multimedia streams; when a presentation object a of the X presentation objects is selected, obtaining a media presentation description file of a multimedia streaming service j that has an association relationship with the presentation object a; and obtaining m1 multimedia streams of M multimedia streams according to the media presentation description file of the multimedia streaming service j. The technical solutions provided in embodiments of the present application help better implement flexible switching between a multi-stream multimedia streaming service and another multimedia streaming service.

Disclosed are a method of performing video call and a display device. The display device includes: a camera; a display, configured to present a window for a counterpart and/or a local window; and a processor, configured to: receive a push message sent from a server, wherein the push message is sent after the server receives a video call request sent from the mobile terminal; automatically establish a call process, and control the display to present the window for the counterpart and not to present the local window in response to the push message when the mobile terminal is authorized by the display device; and reject the video call request in response to the push message when the mobile terminal is not authorized by the display device.

A system and method for enabling the selection of audio associated with one or more concurrently displayed video programs to be controlled. This system and method enable a user to select one or more concurrently displayed video programs and consequently control the routing and volume of the audio associated with one or all of the concurrently displayed video programs. The concurrently viewed videos can be presented in a picture-in-picture format.

An image processing terminal in the media system comprises a receiving unit for receiving a control signal; and a processor for operating the image processing terminal in a specific mode according to the received control signal. A mode when the normal input is applied to a specific key differs that when the force input is applied to the specific key, modes differ depending on a sensing level of the force input, or the modes differ as the force input is applied to different keys, a first mode is changed to a second mode when the force input is applied to the specific key in the first mode, and a sensing level is calibrated to a first sensing level or a second sensing level, when an input applied to the specific key corresponds to an input between the first sensing level and the second sensing level.

Systems and methods for identifying, assembling, and publishing content are described. A content item, such as a video, having a first time length, is identified by a system to be included in a program scheduled for a first time period. The video may be hosted on a third party system. A first span of time within the first program is allocated for the video, wherein the first span of time is longer than the first time length. The system determines, prior to or at the first time period, a time difference between a current length of the video and the first span of time. At least partly in response to determining that the video has a time length shorter than the first span of time, the system selects supplemental content based at least in part of the determined time difference to be streamed to user terminals over a data network within the first time period.

Systems and methods are described herein for providing a media guidance application that resizes content based on a relative importance of the content. For example, a display may have first and second content generated for display. If the first content is more important to a user than the second content, a size of the first content will be increased with respect to a size of the second content on the display. If the second content is more important to the user than the first content, then a size of the second content will be increased with respect to a size of the first content on the display.
