A television program switching method includes that a program selection instruction entered by a user is received when an electronic program guide (EPG) screen is displayed on a mobile terminal, where the program selection instruction includes a program identifier, and where the EPG screen includes at least two program identifiers and first program information corresponding to each program identifier. The EPG is searched for program frequency information corresponding to the program identifier according to the program identifier, and the program frequency information is sent to a to-be-controlled television.

The present disclosure relates to a receiving apparatus and a method therefor which are capable of decreasing a processing load and efficiently improving reproduction quality. A packet accumulating unit stores packets and packet type, and another packet information. A statistics information accumulating unit accumulates statistics information (e.g., an error ratio, performance (processing condition) of the receiving apparatus, a condition of a stream, and a condition of a buffer). A packet-correcting-method selecting unit selects a packet correcting method from a packet correction table generated in accordance with the packet information and packet identification/statistics information from the statistics information accumulating unit, and supplies a packet to be corrected to a packet correcting unit in a case where the packet in process is determined to be a target of correction. For example, the present disclosure can be applied to a communication system that transmits and receives data.

This invention is directed to a receiver device to simultaneous display mirroring streams conforming to at least two different screen mirroring protocols, the different screen mirroring protocols being provided by different device vendors.

Processing circuitry of a connectivity device can receive an audio video signal from a first source. The processing circuitry can also receive an audio signal from a second source. The processing circuitry can transmit the audio video signal to a sink device. When an audio level from the second source exceeds a threshold, the processing circuitry can send the audio signal from the second source along with the video signal from the first source to the sink device.

A method of recording data received as part of a multi-channel data stream includes writing a first subset of initially-received channel segments of a multi-channel stream to corresponding main store locations instead of a write cache while writing a second subset of initially-received channel segments of the multi-channel stream to a write cache instead of corresponding main store locations. The method further provides for writing continuation segments associated with the first and second subsets of the initially-received channel segments to the write cache and flushing a collection of same-channel segments out of the write cache responsive to a determination that the same-channel segments satisfy a coalescence condition.

Original transmitters of television broadcast content, such as national broadcasters, may tunnel various data such as SCTE-35 messages through a special closed captioning service before handoff to their local affiliates. The tunneled SCTE-35 messages may thus survive the re-encoding of both the local broadcaster to an over-the-air (OTA) retransmission, and re-encoding by any subsequent cable or satellite television providers as well. An uplink center and television service provider (e.g., a cable or satellite system) may receive the transport stream from the local broadcaster, may strip out the tunneled SCTE-35 messages from extra closed captioning streams at the uplink, re-create the SCTE-35, and then process it at the uplink of the satellite system, for example, by performing ad insertion, re-muxing the SCTE-35 for the satellite broadcast, and/or modifying it and sending it over the satellite broadcast on a separate PID to the set top boxes for those STBs for ad insertion.

In particular embodiments, one or more computer systems of a social-networking system determine a first media device of a first user of a social-networking system and determine a second media device of a second user of the social-networking system. The one or more computer systems access a social graph of the social-networking system, update the social graph based on the determined first and second media devices, and stream media from the first media device to the second media device using the updated social graph. The social graph includes nodes and edges connecting the nodes, the nodes including user nodes that are each associated with a particular user of the social-networking system and concept nodes that are each associated with a particular media device.

A television program switching method and apparatus, relate to the field of communications network technologies and applicable to television program switching, thereby resolving a problem of cumbersome user operations of viewing television program information. The method includes a program selection instruction entered by a user is received when an electronic program guide (EPG) screen is displayed on a mobile terminal, where the program selection instruction includes a program identifier, and the EPG screen includes at least two program identifiers and first program information corresponding to each program identifier, the EPG is searched for program frequency information corresponding to the program identifier according to the program identifier, and the program frequency information is sent to a to-be-controlled television.

Methods and apparatuses for detecting timestamp discontinuities and video resolution discontinuities within a packet stream and marking locations of the detected discontinuities within the packet stream are described. Prior to transmission of the packet stream, an electronic device may perform timestamp discontinuity detection by acquiring a sequence of packets to be transmitted, identifying a first timestamp associated with an earliest packet within the sequence of packets, identifying a second timestamp associated with a latest packet within the sequence of packets, determining a timestamp time difference between the first timestamp and the second timestamp, determining a maximum chunk time difference based on a data rate at which the sequence of packets were encoded and a data size of the encoded packets, and detecting that a timestamp discontinuity exists within the sequence of packets if the timestamp time difference is greater than the maximum chunk time difference.

The present invention is intended to permit both real-time display of a picture represented by a non-compressed video signal on a television and display of a picture represented by a compressed video signal at any desired time by simultaneously transmitting the compressed video signal and non-compressed video signal via one interface. An STB packetizes a compressed video signal, and multiplexes the compressed video signal and a blanking signal combined with a non-compressed video signal. Thus, both the video signals are transmitted simultaneously. A picture represented by the non-compressed video signal is displayed on a television in real time. The compressed video signal is stored in a storage medium incorporated in the television, read at any user's desired time, and decoded so that a picture represented by the compressed video signal can be viewed at the user's desired time.
