Abstract: A mobile device may be registered to participate in selection of television programming for presentation by a display device external the mobile device. An indication of selection of particular television programming for presentation by a display device may be received from the mobile device. A determination may be made, based on the indication of selection, whether a collective indication of selection tally of the particular television programming is greater than a collective indication of selection tally of other television programming. The particular television programming may be output for presentation by the display device when the particular television programming has a collective indication of selection tally greater than a collective indication of selection tally of other television programming.

Abstract: Systems and methods are presented that permit an individual to share digital video between video devices using a cable television system. A first video device streams digital video to a cable headend, which transcodes it and stitches it with other video content, such as a menuing system. The headend then transmits the digital video to a second video device, such as a set top box, for display. The data stream may be controlled using a standard set top box remote control, and the system may be used without purchasing additional hardware or software, or configuring a wireless local area network.

Abstract: A method of and apparatus for allowing a user using a communications device (14,15) to interact with first media material that is broadcast on a first broadcast channel y a first broadcast media source and second media material that is broadcast on a second broadcast channel by a second broadcast media source, the first media material and the second media material include a first media ite and a second media item, respectively, the first media item and the second media item are associated with a first representation of the first media item and a representation of the second media item, respectively, that are received and presented by a broadcast reception device while the broadcast reception device is tuned to a third broadcast channel. The method includes maintaining in a temporary storage an item identifier, the item identifier identifies one of a first media item-related information and a second media item-related information. Additionally, when the broadcast reception device is tuned to the third broadcast channel and presents the first representation of the first media item, the method includes providing the item identifier as a basis for identifying the first media item- related information, the first media item-related information is a basis for a response to an interactivity activation made in reaction to presentation of the first representation of the first media item by the broadcast reception device. When the broadcast reception device i tuned to the third broadcast channel and presents the first representation of the second media item, the method includes providing the item identifier as a basis for identifying the second media item-related information, the second media item-related information is a basi for a response to an interactivity activation made in reaction to presentation of the representation of the second media item by the broadcast reception device.

Abstract: A method for transmitting system information on a PBCH is described herein. A transmission/reception point (TRP) may generate a concatenated master information block (MIB) transport block that includes information bits associated with system bandwidth information, timing information, system frame number (SFN), a beam sweeping configuration, and a control resource set (CORESET). The TRP may then attach at least 16 cyclic redundancy check (CRC) bits to the concatenated MIB and then prioritize the concatenated MIB and the at least 16 CRC bits based on content. The TRP may then perform channel coding of the prioritized concatenated MIB and the at least 16 CRC bits to produce coded bits using at least one polar encoder with a coding rate that is less than 1/3, perform rate matching via repetition on the coded bits, and then transmit the rate matched, coded bits on the PBCH of a radio frame.
