摘要:
The disclosure relates to a method of determining complexities and/or quality of video segments of a video program and providing data indicating the quality of video segments to user devices. Such data may be included in a manifest file of the video program. Based on the data indicating the complexities and/or quality of video segments, a user device or the system may choose a bitrate version for each video segment that minimizes network bandwidth usage while providing sufficient video quality.

The present technology relates to a receiving device, a transmitting device, and a data processing method that can flexibly control operation of an application associated with content. Effective period information indicating a period in which an application associated with content can specify one of a first mode for controlling operation of the application according to the period and a second mode for controlling the operation of the application according to intention of an end user and, in a case where the second mode is specified as the effective period information, the operation of the application is controlled in response to an operation by the end user. The present technology can be applied to a television receiver or the like, which can receive terrestrial broadcast, for example.

A method and apparatus are provided for performing adaptive streaming according to a streaming environment based on information about a plurality of elements for determining qualities of a plurality of media data with respect to the same content.
摘要:
A method and an apparatus for synchronizing media data and auxiliary data received by a service through a broadcast network or a communication network in a multimedia broadcast service are provided. The method includes receiving regular media data provided for a broadcast service, receiving and storing control information regarding adjunct media data comprising auxiliary data regarding the regular media data, determining location information of the adjunct media data included in the control information, and receiving and storing the adjunct media data according to the location information. If an identifier of the adjunct media data is included in a header of the regular media data, reading the stored adjunct media data corresponding to the identifier of the adjunct media data, and executing the adjunct media data in synchronization with the regular media data according to synchronization information included in the header.
摘要:
A configuration is realized such that a playback application applied in a receiving device can be determined using a service category identifier recorded in an SLT that can be received in advance. The service category identifier capable of identifying an application applied to a provided service such as a program provided by a transmitting device is transmitted to the receiving device. The receiving device performs a continuation process on an application applied before service transition when the service transition occurs and when applications applied to services before and after the transition are same. The service category identifier is an identifier capable of identifying the service by determining whether to apply a residential playback application or a broadcast playback application for playback of the service.
摘要:
Emergency alert information is suitably transmitted by utilizing a broadcast service. A preamble section 31 of a transmission frame having a 100 ms interval includes a tuning data section 31A and a reserved bit section 31B, and is made up of a designated total bit length. The tuning data section 31A stores L1 data for tuning to a relevant broadcast channel on the receiving side. Also, the reserved bit section 31B inside the preamble section 31 stores emergency alert information processed by an emergency alert information processing unit 202. In a predetermined message mode, emergency alert information having a predefined message is expressed in a binary format and transmitted in just one frame.
摘要:
The present invention proposes a method for transmitting a broadcast signal. The method for transmitting a broadcast signal according to the present invention proposes a system capable of supporting next-generation broadcast service in an environment supporting a next-generation hybrid broadcast which uses a terrestrial broadcasting network and an internet network. Also, the present invention proposes an efficient signaling method which can encompass both the terrestrial broadcasting network and the internet network in an environment supporting next0-generation hybrid broadcast.
