Hybrid broadcasting and communication services are made excellently implementable. A transport stream obtained by time-division multiplexing a first transmission packet including a predetermined component and a second transmission packet including information on the predetermined component is generated. The transport stream is transmitted along a predetermined transmission path. Information on a plurality of distribution protocols, the information on each distribution protocol including at least location information and protocol identification information, for acquiring a specific component to be acquired on a communication path, or acquisition information for acquiring the information on the plurality of distribution protocols is inserted into the second transmission packet, in relation to the specific component. A receiving side can excellently receive the specific component through a distribution protocol in accordance with its own distribution network environment.

A wireless communication device and an image display apparatus including the same are disclosed. An image display according to an embodiment of the present disclosure comprises a display, a memory to store country code information, a signal processing device to output an image signal to the display, and a wireless communication device to perform wireless communication with an external device, wherein the wireless communication device is configured to scan a beacon frame, set wireless channel and wireless transmission power based on the country code information stored in the memory in response to a beacon frame being not received within a predetermined period, and in response to the beacon frame being received within the predetermined period, extract the country code information within the beacon frame and set wireless channel and wireless transmission power based on the extracted country code information. Accordingly, it is possible to efficiently perform wireless communication.

A system for augmenting a broadcast with virtual content, the system including a client device for viewing the broadcast, at least one camera for receiving a primary image frame of the broadcast, at least one upstream device in communication and associated with the at least one camera, and, at least one downstream device in communication with the at least one upstream device, wherein the system is configured to determine client identification information associated with the client device, determine one or more virtual content based on the client identification information and augment the primary image frame with the virtual content to be displayed on the client device.

Techniques for real-time audience measurement are provided. The techniques include instant message protocol in a DVR environment to obtain real-time audience measurement data to modify the scheduled recording time of a media content in real-time, to bookmark in real-time, and to gather audience ratings on commercials and viewership in real-time.

A method is disclosed for monitoring the audience of an advertisement over a content distribution system, the advertisement comprising an advertising message associated with an audio content. The method comprises: inserting, within the message, an advertising identifier associated with the advertisement and distributing the audio content with the advertising message to a user of the content distribution system; at a first user device configured to receive the audio content, playing the audio content with the advertising message; at a second user device connected to the first user device and configured to communicate with a data collection server over a data communication network, retrieving a customer identifier uniquely associated with the user; and, during or after playing, sending by the second user device the customer identifier and the advertising identifier extracted from the advertising message to the server to monitor the audience of the advertising message.

A system and method facilitate digital marketing for sponsors of live television broadcasts. The system allows a user, using an application on a computing device while a piece of sponsored content is being broadcast, to express an interest in the broadcast piece of sponsored content and the interest of the user is communicated to a backend system that selects an endpoint destination associated with the broadcast piece of sponsored content wherein the endpoint destination is a pointer to further digital information about the broadcast piece of sponsored content. The system and method may periodically change the selected endpoint destination based on an event in the sponsored piece of content.

Systems and method for the transmission and receival of data between one or more sensors configured to measure physiological parameters and one or more further sensors and devices. In particular relating to data transmission where a direct connection is not formed between the sensors and devices and the transmission is initiated or controlled by a remote processor. In some cases a method of receiving medical data on a first device, the method comprising the steps of: Receiving, from a remote processor, transmission parameters for a second device configured to transmit physiological parameters; Monitoring a broadcast channel; Receiving, on the broadcast channel, a data packet from the second device; Determining the physiological parameters from the second device based on the transmission parameters.

Computer-implemented method (100) of mixing audio for a virtual audience (10) of a broadcast performance. Individual audience members of the virtual audience (10) participate via respective user terminals (6). Each audience member has a respective virtual position (12) in a model (14) of a real-world performance venue associated with a respective set of acoustic characteristics for modelling acoustic responses of the real-world performance venue at corresponding real- world position. The method (100) obtains a plurality of audio input signals sent from respective audience members and determines an audio output signal for output to a respective audience member, the audio output signal determined by adjusting the plurality of audio input signals to account for: (i) the respective sets of acoustic characteristics associated with the virtual positions (12) of the audience members; and (ii) a spatial relationship between the virtual positions (12) of the audience members.
