METHOD FOR ENCODING/DECODING OF VIDEO SIGNALS AND DEVICE FOR THIS Russian patent published in 2022 - IPC H04N19/625 H04N19/18 

FIELD: IPTV.

SUBSTANCE: invention relates to the field of Internet Protocol Television (IPTV) and, in particular, to a method for changing a channel. Methods, systems and devices for wireless communication are proposed. In order to communicate over a predetermined wireless communication network, a wireless device may first perform a cell acquisition procedure (eg, to determine cell specific information such as timing and frequency offsets, bandwidth, control channel formatting, etc.). In some systems, aspects of timing information may be carried using scrambling codes applied to a master information block (MIB). Physical Broadcast Channel (PBCH) payloads, including MIB transmissions, may be jointly coded with sync signal indices. Bursts of MIB transmissions can thus be decoded without blind decoding, while maintaining error protection and low latency that may be required to retrieve critical system information in the MIB.

EFFECT: invention provides a channel change method and corresponding device, increase the channel change rate, reduce the channel change time, and save bandwidth.
