Abstract:
A method and system for multiplexing of multiple channels of video data through a single analog broadcasting channel is disclosed. The method enables a spatial and temporal multiplexing of videos of each of the multiple channels. The multiplexed content is created as a result of multiplexing that is encoded to generate digital transport stream that is transmitted through analog medium. The system enables a STB receiver to decode each of the videos from the stream. At least one video from the multiple videos is played on the television based on user selection.
Abstract:
The disclosed apparatus for receiving a broadcast signal including 3D content comprises a receiving unit configured to receive a broadcast signal including video data for 3D content, a decoder configured to decode the video data for the 3D content from the received broadcast signal, a signaling processor configured to parse depth information from the decoded video data, a graphic engine configured to determine a depth for displaying an on screen display, OSD, of a receiver, a formatter configured to form images including the OSD located at the depth for the 3D content, and a display unit configured to display the images, wherein the depth information includes partition information indicating partitioning pattern of an image, several regions of the image are defined by the partition information, wherein the depth information further includes max disparity information specifying maximum disparity value in the image and min disparity information specifying the minimum disparity value in a region of the several regions.
Abstract:
A method of operating a multi-stream reception scheme, such as DOCSIS (Data Over Cable Service Interface Specifications), comprising at least two receivers (10, 12, 14) having respective voltage controlled oscillators (16), the method including monitoring a change in local oscillator frequency in a selected one of the at least two streams and, if the frequency distance between the local oscillator frequencies is below a value likely to cause pulling or coupling between the voltage controlled oscillators of the at least two receivers, resetting the frequency planning of the selected one of the at least two streams to maximise the frequency distance of the voltage controlled oscillator of the selected stream with the voltage controlled oscillators of the or the other streams.

Abstract:
Disclosed is a broadcast receiver. The broadcast receiver comprises a signal receiver for tuning and outputting a channel of a digital broadcasting signal, a demodulator for demodulating a signal of the received channel and checking a lock state or an unlock state of a gain control signal and a timing control signal of the channel, and a demodulation controller for controlling an operation of the demodulator and detecting a lock state of the channel based on the lock state of the gain control signal and the timing control signal.
